Frack!

I don't know enough about hydrofracturing to get oil out of the ground to determine whether it is alright or not. But injecting chemicals into the ground to aid it? That is nuts.

http://www.nytimes.com/2011/04/17/science/earth/17gas.html

WASHINGTON — Oil and gas companies injected hundreds of millions of gallons of hazardous or carcinogenic chemicals into wells in more than 13 states from 2005 to 2009, according to an investigation by Congressional Democrats.


Companies injected large amounts of other hazardous chemicals, including 11.4 million gallons of fluids containing at least one of the toxic or carcinogenic B.T.E.X. chemicals — benzene, toluene, xylene and ethylbenzene. The companies used the highest volume of fluids containing one or more carcinogens in Colorado, Oklahoma and Texas.

Millions of dollars have been spent remediating older leaking underground storage tanks used at gasoline stations. the primary contaminants were BTEX.

I live in PA, right in the center of a shale formation being fracked right now. There are two sides to every story.

Gasland is utter sensationalist bullsh#t. I can't even start a conversation with it because every single facet is twisted to be inflammatory.

People are in an uproar becuase they are injecting diesel fuel in places with the frack water. Where do you think the diesel came from?! The fact that the aquifer is 100 feet down and the gas is 5,000 feet down seems to go over the heads of many folks.

I've seen wells lit on fire around here for decades before the gas companies showed up. The natural gas is, well, natural. It's been in the water here for as long as people have been drilling water wells.

There are some companies doing a lousy job. Cabot Oil and Gas seems to have an environmental policy along the lines of "it's better to ask forgiveness than permission".

Forunately, they seem to be in the minority. Overall it seems to be a fairly low-impact means of feeding our fossil fuel habit. I think the debate on the sources of and issues with that habit belong elsewhere. But accepting that it's going to come from somewhere, even with all this occurring in my back yard, I'm not crying NIMBY.

No matter how the PR campaigns paint it, if you take a look at what they have done around the country already, you will come to the conclusion that fracking is not good for any human being, or animal.

Hi Base.. thanks for that explanation of drilling and fracking. That was cool. Can you help me understand something. The NY times article says they use chemicals in the process of fracking, including things like benzene, but you seem to say that they only use fresh water.

Maybe I misread this, but would you address the use of chemicals? It does appear to me that you are saying that ground water is being protected by all of these steps you explain, the cementing and such.. But could you expand on the use of chemicals? And what that article is saying.

We have a big energy problem on this planet. Nuclear looked good until the Japan incident, much of the world's oil has a big political issue, and wind&solar can't fill the gap. We should conserve and use less but this won't fix the problem.
Shale gas and shale oil will go a long way on this continent to helping us manage for longer. Shale gas in particular is abundant in some areas and should play a much bigger role in the future as it is probably less damaging than the alternatives. In fact we should stop using coal for electricity generation and use more gas.

Thanks Base,

when I started this thread my main concern was in two areas; the potential for contamination to groundwater, and that the regulators actually do not require the fracking fluid to be identified. I saw that the "recipe's" are proprietary, and my response is that it is my earth too and I want to know what is being injected, pretty simple.

Base, you posit that oil business is not extracting oil in ways that may be dangerous because they are afraid of environmental costs. I counter that that fear of a possibility of punitive measures versus the certainty of profit now has led to many abuses. For example, what happened in the gulf.

My mom worked for an oil businessman and asked him if he wasn't concerned about global warming affecting the polar bears. He said, "Who cares about the polar bears?"

I haven't seen anybody ask about what happens to the fluids after they are used in the fracking process for disposal?

Much of it is flushed through municipal wastewater treatment plants that is then flushed downstream in rivers used for drinking water of 18M people!

This fracking fluid contains BARIUM, STRONTIUM, AND OTHER RADIOACTIVE ELEMENTS. And who knows what else is in the fluid as the O & G industry is not required to reveal what they use in their fracking fluid...

But hey, no big deal...people can buy bottled water if they are worried about their tap water being contaminated.

Our drinking water is precious. One of the reasons that we Americans have good drinking water is not because of high tech water and wastewater treatment, but because we protect the raw water supplies (surface and ground).

It is sometiems scary what Publicly Owned Treatment Works (POTW) can process through their wastewater treatment systems. Frequently, those technologies employed do not remove the contaminants, but through shear volume the dilution will then allow the POTW to meet effluent requirements.

At one Superfund Site I worked on, the Record of Decison (ROD) was to treat through Carbon Adsorption some 1 million gallons of pesticide (compounds such as Aldrin etc. now banned) contaminated water. I designed and specified a system for the contractor do do this. When the contractor was out getting ready to do the work he called me and wanted relief as he said that the local POTW that discharged into the Mississippi River would take the contaminated water with no pre-treatment. There would have been minimal treatment of these compounds in that plant. Given the logic, that the POTW would not have removed the contaminants, it was then a dilution process. Needless to say that contractor was unhappy as I disallowed his request.

The point here is that protecting our groundwater is essential. I totally understand that there are instances where the fracturing will have no impact on GW aquifers. However, for a regulatory process to not even understand what is being injected is unacceptable and not confidence inspiring.

Base - good to hear from someone with experience in the drilling industry. I read through most of your posts (but hey, they're waaay long), and they nail it pretty well. When it really comes down to it, the probability of aquifer contamination from the actual fractures down-hole is extremely low.

Dick Luger brings up the more important point - where we are taking the contaminated fracking fluid. That's how it's getting into our drinking water. The article he posted is very informative.


Sort of off-topic, but sort of not: it seems that everyone forgets about geothermal energy as a sustainable almost zero emission source of energy/electricity. There is a technique called Enhanced Geothermal Systems that uses hydrofracturing to create fracture zones in "hot, dry rock" that, if someone can figure out how to get it to work, could open up huge potential all over the west for geothermal. Perhaps we can learn from the mistakes we're making now in hydrofracking when using the technique for other avenues...

Edit: Also to add: Studly - the companies that be are constantly monitoring the status of their existing wells, mostly to monitor their output. There's a special wireline caliper tool that can measure the thickness of the casing - if there is a spot in the casing that is showing more wear, or the possibility of cracking, the company will go to steps of repairing it.

Yeah, I was on a tear of deleting my posts for a while. Sorry.

The problem is that the hysteria is so wrong. They don't even know why the Marcellus in the northeast is a terrible place to frac. I can explain it in two paragraphs. I am working, though.

I am on a long consulting contract with one of the biggest horizontal companies in the country, so I get to sit in on the engineering meetings and all that. I know pretty much every play in the country.

It isn't a problem in TX, LA, OK, ND, etc. We have the infrastructure and good geology to deal with the fluid disposal.

In the northeast they have no way of disposing of the water, which is bad when it flows back because it is mixed with formation water that is high in chlorides. Saltw#ter in the groundwater is the worst. You can't clean it up. I heard that they were using produced saltw#ter to salt roads in Pennsylvania or one of those Marcellus areas. You would go to prison in OK for doing that.

Frac jobs involve moving a lot of fluid around. It isn't that nasty, but I wouldn't drink it.

The real crime here is that 90% of the hysteria is based on zero science. Nobody noticed that Obama opened up the Chukchi and Beaufort Sea to drilling. Much of the Beafort area starts at the three mile limit offshore of ANWR. The eskimos are a maritime people, so they wanted the onshore drilling. They are freaking out about the offshore drilling permits and have joined in lawsuits.

Now. Those places have ice 9 months or so out of the year. How are you going to have a spill plan? The Chukchi is also really shallow, and at least near the shore, the ice bulldozes the sea bottom. I have no idea how they are going to protect the pipelines. That is the reason that the proposed gas line from AK to the lower 48 had its route changed. The Canadians wanted it to follow the coast and pick up the McKenzie Delta stranded gas. Too risky.

All this happened a while back, and nobody noticed. The leases in the Chukchi Sea (north of the Bering Sea) went for billions, so there must be some damn good geology over there.

Gasland is total crap. There is actually one part of it that is a real pollution problem.

Gas prices are in the toilet, so the drilling has really slowed down. It is all oil zones right now.

B104: That is the reason that the proposed gas line from AK to the lower 48 had its route changed. The Canadians wanted it to follow the coast and pick up the McKenzie Delta stranded gas. Too risky.

Would it not have also picked up oil from the Canadian side of the Beaufort Sea, and perhaps farther east in the Arctic? IIRC, they did quite a lot of exploratory drilling in the Beaufort Sea, and found a fair bit of oil (and gas), with promise of more. It's been sitting since then, as it's too expensive to safely get out and ship, plus the tar sands came on stream. And no one really knows how much is there, plus our countries continue to squabble over where the Beaufort Sea boundary is.

MH,

The proposed line was a natural gas line, not an oil line. The economics simply aren't there for any route at this time. Who knows maybe they'll end up needing the gas to produce the massive heavy oil field that lays under prudhoe bay, but which is currently not technically or economically able to be produced. As it is the gas has been used to help with Enhanced Oil Recovery (EOR) for the past several decades, so it really has been better to recycle and use a portion of the gas to get the more valuable oil to market then to ship it South.

There currently is some production occuring in the Beufort, Endicott Island has been producing for decades, and Northstar has now been in production for a decade.

Been some time but maybe two-three years ago they used this system if I recall just north of San Francisco, Napa Valley area? Drilled down to cap geothermal energy and their thinking was using crack systems would work better. Started a few earthquakes in the area and had to stop production so lost investment.

Core drilling for thermal storage is OK there is a difference. Software for soils underneath to show compostion where water and fines,rock and voids.

Doing one here myself will supply heat and cooling for three houses, if I go deeper add more bore holes can have my own utility company and supply 30-40 homes. Passive solar plus electric. Net zero but calculations going for -15. -15 meaning I can sell extra eletricity or have the swimming pool heated during the winter time 24 hours.

Despite having had graduate level courses in Hydrogeology, I dont know enough to have a informed opinion on whether hydrofracking is alright or not. However, using fracking fluid that contains contaminants to our drinking water supplies is just plain wrong. You can't dump unknown fluids above ground or in surface water supplies and trust me, it is way more difficult to clean up if it is in the groundwater. At a minimum, hydrofracking fluids should be regulated to prevent the introduction of contaminants into the ground.

So Base regarding the EPA findings

Chemicals found in a Wyoming town's drinking water likely are associated with hydraulic fracturing, the Environmental Protection Agency said Thursday, raising the stakes in a debate over a drilling technique that has created a boom in natural-gas production.

The agency's draft findings are among the first by the government to link the technique, dubbed "fracking," with groundwater contamination. The method—injecting large volumes of water, sand and chemicals to dislodge natural gas or oil—has been criticized by environmentalists for its potential to harm water supplies, which the industry disputes.

Are you saying the EPA is wrong or just a case of a good technique backfiring by being used in wrong places?

What to do? The industry moans about regulation but when unregulated, somebody abuses it until theres a deadly mess

I saw the EPA release this morning. All of that stuff gets sent to me.

My "guess" is that it is probably real. I am pretty sure that where they are working is the Jonah field. That sucker has so many wells in it that it is like a pin cushion. It isn't a horizontal shale gas area, though.

I will tell you this. There is nothing as nasty as an old oil field. Wells that were drilled in the fifties and sixties are usually depleted and plugged by now, but they are famous for groundwater problems. The biggest problem by far is saltw#ter contamination from old water floods. There are huge problems with that, and it is mainly historic.

What freaks all of us out about the EPA is that in the older producing states we have a very strict regulatory structure on groundwater protection. It isn't very expensive to do, so I have never heard a peep.

The base of fresh water is known pretty much everywhere in the producing basins. The state requires that you case and cement off the fresh water. Most wells have several casing strings between the producing casing string and the annulus of the surface casing. The string over fresh water is called surface casing.

Anyway, to even get approval to drill a well, the state gives you orders on casing requirements to protect the groundwater. It is no big deal at all, technology or money wise. It is now super difficult to get approval for a waterflood. That is where you go into an old, depleted, field, and inject produced saltw#ter back into the formation to bring the reservoir pressure back up and then "sweep" it from the injection wells to the producers.

If there is an old well in the area that was drilled from the sixties or earlier, it probably doesn't have adequate surface casing. So as you pressure up the reservoir, that saltw#ter migrates right into that old wellbore and right up into the groundwater. To get approval, you have to go back in and plug those wells properly, which is often not possible because when they plugged a well back then, they threw all kinds of junk down the hole. So if you do have that problem, most companies won't even try it.

There are other things that are state specific. In southern Kansas, there is a salt layer that is 1000 feet thick in some places. It outcrops around Hutchison, KS, and there are big mines there.

So when you drill through it, your drilling mud chlorides go way up and if it doesn't get hauled off and handled properly, you can get chlorides in your groundwater just from leaking through the pit. So the state of Kansas, who has known about this problem from zillions of wells, makes you deal with it in a very specifically regulated way.

Another thing in Kansas. There is a zone in the mesozoic section called the Cedar Hills sandstone. Where it exists, the saltw#ter in it is notoriously corrosive. It will eat through your production casing in three years and you will totally lose your well. So in those areas, you have to run what is called a DV tool or port collar. It is just a device that you screw into your pipe when completing a well. After you do the initial cement job you have to come up and then do a second cement stage uphole over the Cedar Hills.

Also, in dry holes, when you plug them you are required to set a big cement plug over the Cedar Hills, because it is beneath the Dakota and Ogalalla aquifer. It doesn't cost jack to set that extra plug.

The problem is that you can't re-enter old dry holes in that area of Kansas because when you are drilling out the cement plugs to get down to some old, by-passed pay zone, the drill bit will not stay in the hole. It will hit that cement plug and kick off into the Cedar Hills 75% of the time. So nobody even tries it. They just drill a new well.

There is all kinds of specific stuff like this that the old producing states know about. In the modern age, nobody wants an environmental problem. It isn't a fine from the EPA or state you worry about. It is a landowner lawsuit for trashing his groundwater. Those are enourmous lawsuits and can bring a small company to its knees. They are a nightmare for big companies because it makes the press and the bad news is also a nightmare.

I tell ya. The bigger companies who drill in the U.S., which are almost all big "independents," have massive environmental compliance departments. If there is a blowout or spill, they show up all moon suited up within hours.

Bullwinkle has a link upthread to a shale gas well that somehow got loose when it was flowing its frac water back. That was a mess, but it was contained and cleaned up.

The big independents are the ones who developed the shale gas technology. Now the majors are in on it as either joint venture partners or by buying an existing company.

I hate watching the Exxon commercials about how we have all of this safe natural gas around. Well, yeah, we do have all of this natural gas in certain shale formations that we can now recover, but the guy has a sneer like a used car salesman. Plus, I don't like the major companies too much anyway. A lot of these companies are run by true believers who rip global warming and all kinds of environmental concerns.

Hell, I have been reading stuff on climate change for twenty years. I believe it. I certainly feel that it can't be discounted willy nilly like Rush Limbaugh does.

Iran provides a good example. In the middle east, and specifically Iran, there are truly monstrous natural gas fields. Since there is not much of a market for stranded gas that far from a market, it just sits there.

Iran's production has peaked and is now declining. Well, they make all of their money from oil exports. So they are converting to natural gas as a transportation fuel and selling the oil that would have been used domestically.

We are in a similar situation, although our energy requirements are huge. We are swimming in natural gas. It makes a great fuel, but you have to fill up your tank much more often.

Fleet vehicles like USPS, UPS, buses, etc. are all moving into natural gas if they haven't already done it.

Now. Burning any hydrocarbon or coal puts carbon into the atmosphere. Natural gas is the least carbon intensive, so it makes sense to switch to natural gas while waiting on cleaner technologies.

Trust me. I shout from the hilltops that we need to stop burning hydrocarbons. The problem is that no matter how expensive oil gets, it always seems to be cheaper than alternatives.

Biofuels are just a way to make fake oil. No good. All you wood burners are even worse.

It makes me ill to see all of the SUV's and other gas guzzlers out there on the road. Just count them as you drive.

Like anything, you have to educate yourself on issues just to be able to climb above the bullsh#t. Frac jobs are no problem in most places. When a problem is discovered, it should be acknowledged and fixed. Simple.

Now imagine some kid lording over your drilling intent documents who doesn't know jack about how anything works. That is why we like the states, who have been dealing with this issue forever. A rule for the Cedar Hills in Kansas doesn't apply for a well in the Arkoma Basin. The Cedar Hills was never even deposited there.

That is why we fear the EPA. They will take a normal well and then turn it into a paperwork circus that accomplishes nothing.

That said, in the Marcellus Shale in the NE, some of the states have little history of oil and gas production. So they don't have a regulatory arm that is worth a damn. On top of that, they have no way to deal with the used frac water, although they are trying to recycle it and other crazy things.

But drilling isn't inherently bad. The reason that I am so opposed to drilling in ANWR is almost asthetic. I have been there quite a few times. I would hate to see it industrialized. That and the reserve numbers are always inflated or imaginary. I have read the 2 CD set on the USGS assesment.

But hey! Obama just opened up the offshore up there. Dealing with a spill on land is easy. Dealing with a blowout on land is easy. In water, everything is harder. In an area covered with ice most of the year, I can't even imagine how a problem will be dealt with.

So everyone is crying about frac jobs and in the meantime you haven't heard a peep about that.

Base - 1st, I gotta say sorry for no believing a word you've got to say about the subject of hydrolic-fracturing. If you get paid to do it, then it seems to me that you would probably say just about anything to keep the money flowing. Just like hookers want to legalize prostitution.
I'm also sorry if it seem that I am making smaller an issue out of this than it is (to you/others)

I go on the basis of a few easy steps/questions to get to the bottom of wether I feel the search and extraction of underground natural gas is a good thing or a bad thing.
My biggest question comes down to water: How long has the water been flowing cleanly? After a frack operation is put in place is the water safe? If I had access to the GreedEO I'd hand him a glass of fresh tap water from the places that he drills in and ask him to take a drink.

Second question is: If its so safe… then why are there any questions about any of it? In other words if you dig a hole in my next door neighbors backyard and pump water/chemical slough into the ground and get all kinds of gas/goodies out of the ground and I don't know about it…? Would I have a problem? NO!!!! I'd not have a f*#king problem with that because I have not been effected. However, in the same situation I find that within months my tap water has a funny taste/smell/fumes….? THEN I HAVE A F*#KING PROBLEM!!!!!

If it was all that safe nobody would really know too much about it. But because it isn't safe.. we've all already heard enough.

In 50 years the original protective casing will rust out and voila, there is your pathway between aquifers. Very few energy/engineering companies want to do those corrosion/material evaluations as they will then show negative results that must be dealt with. It is simple for companies that are out to turn a profit. If you don't want to know the answer, then don't ask the question.

Aside from the above issue, Base, what is your position on injecting proprietary fluids into the aquifer in order to frack?

It can be safe or it can be dangerous, depending on the formation and who does the work and how carefully. The real quetion is, what form of energy has the least environmental impact? There is no green energy source, neither is there a source that has no environmental impact. In many cases natural gas is a good source of energy that can be produced w/o trashing the environment, but not in all locals.

Just like climbing, some people shouldn't climb because they'll best their azz even on a G rated route, whereas there are others that can lay it on the line even on the diciest routes.

However, using fracking fluid that contains contaminants to our drinking water supplies is just plain wrong.

I'd be more worried about gas and hydrocarbons making their way up through the microfractures over a longer period of time, rather than just the initial fracking fluid.

Once a well is drilled, the companies will often pump steam and water down the wellbore to help extract the gas from the formation (am I right Base?). Doing this over a period of several years strikes me of having more of an effect on an aquifer than just the initial fracking.

Also Golsen - for what it's worth, yes wellbore casing can rust through, but companies are generally required by law to "plug and abandon" wells that have too much environmental risk or are just tapped out. Generally operators have a pretty good idea of the condition their well casings are in. If anything, they'd fix a bad casing job because it means more resource from the formation ($$$), rather than for environmental concerns...

I understand what you are saying jfailing. But abandoned casing will rust around the whatever material is used for sealing the well. Whether or not that is a significant enough conduit for groundwater migration through the now non-existant casing will be dependent upon a number of factors such as pressure, gradient, etc. of the affected aquifers.

My main point is that proprietary or unregulated substances should not be allowed into the fracking process. In my opinion, the rules about adding any substances to anything underground should be similar to those above ground. 50 years ago we also though it was ok to dump into the oceans. Out of sight out of mind. We seem to have the same mentality here and my concern is that it will come back to bite us.

Lostinshanghai - the drilling program you're referring to never actually made it to the point of hydrofracking... I think they had a grip of problems with the well they were drilling, got stuck a few times, and abandoned the project. So no, they didn't create any earthquakes from that particular project.

Technically it is possible to induce seismicity through fracking - we like to call it "microseismicity." And there are measures that folks can take to minimize sizable seismic events, like drilling through a known "smaller" fault. Ideally you frack a seismically stressed area that will open up fractures that have been healed by secondary mineralization - essentially just speeding up a natural process.

The reason that the Geysers project rose so much controversy over inducing earthquakes, was because it's close to Santa Rosa. People were flipping out over the drilling folks causing earthquakes... Even though... They freaking live ON the San Andreas fault... NIMBY I guess.

Edit added:

Base - 1st, I gotta say sorry for no believing a word you've got to say about the subject of hydrolic-fracturing.

Drilling/fracking is a lot different than prostitution. One reason this subject has become so controversial is because people don't actually really know what's going on. They listen to the media and Gasland and base their knowledge off of that... So refusing to listen to Base just because he works in the industry and may be biased is silly.

No. Not nuts. Risk/benefit analysis says drill baby drill.

http://myprogressnews.com/content/marcellus-shale-and-horizontal-drilling

Underneath our feet are virtually underground “vaults of money” just waiting
to be unlocked. Land owners who hold mineral rights to these “vaults” have
seen their stock rise exponentially over the past years.

A common ten dollar per acre offer several years ago, can now yield up to
three thousand dollars per acre in our reading area. A 100 acre property
once worth one-thousand dollars in mineral rights, today can yield $300,000
plus royalty payments.


....many companies utilize a technique called “Rotary Steerable”.
Essentially this method rotates the whole drill string instead of just the
mud motor. Rotary Steerable enables a driller to drill faster as it
provides a better penetration through the formation. And at an
approximate $25,000 per day for a horizontal rig, quicker translates into
a higher profit margin.

Once the horizontal drilling is compete, the next phase or the frac begins.

Three earthquakes strike Gorda plate near northern California
December 9, 2011 – CALIFORNIA -

Three earthquakes rumbled through Northern California late Wednesday and early Thursday, but the temblors probably weren’t connected, geologists said.

A magnitude 4.0 quake hit around 9:19 p.m. Wednesday roughly 85 miles southwest of Eureka. The quake was 1.2 miles below the ocean floor, geologists said. Then just before 2 a.m. Thursday, a 3.3-magnitude quake struck about 25 miles north of Santa Rosa in The Geysers, where geothermal energy reaches the surface. Roughly seven hours later, at 9:16 a.m., a magnitude 3.8 quake hit 25 miles south of Eureka – 60 miles from where the Wednesday night earthquake was centered.

No damage was reported in any of the temblors. The collection of quakes was probably nothing more than coincidence, said David Schwartz, an earthquake geologist with the U.S. Geological Survey. “It is very hard to say that there is any cause and effect between them,” Schwartz said. “In any 24-hour period, you could get quite a number of earthquakes in California.”

A major earthquake can set off a chain reaction, Schwartz said. But “these quakes are so small and their effects are so local, that I have trouble believing that they are related.’ The earthquakes erupted along the tension point of the lower Juan de Fuca, or what is known as the Gorda plate as can be seen in the 2001 map above. –SF Gate

We are getting innundated with fracking wells here in Appalachia.

Our nice, quiet rural areas are now populated with noisy steel towers that run 24-hours a day and are brightly lit. There is one well 2 miles from my home. I used to be able to see the stars from my back deck, but there there is so much light at the well I can't even see the stars anymore. And when I lie in bed at night all I can hear is the noise from the well site.

The politicians are in the pockets of industry. Whatever solution they are pumping into the ground has been declared "proprietary information" by law. The mining companies don't have to tell anyone what they are pumping into the ground and it is unregulated.

One of the local towns passed a law prohibiting fracking within city limits, and were promptly hit with a $5 billion lawsuit from the industry.

Our quiet country roads are now busy byways, full of large trucks and HALIBURTON pickup trucks with out-of-state license plates speeding at 70 m.p.h. through our formerly quiet neigborhoods where the speed limit is 40 m.p.h.

I had one of these large solution trucks pass me on a double-yellow line even though there was on-coming traffic. He didn't care, he just made everyone get out of his way. I was doing 55 m.p.h in a 55 zone and he passed my like I was standing still. The on-coming cars were forced off the road by the truck. The police won't do anything.

An important aspect of fracking that nobody seems to recognize is the amount of water that is being diverted from watersheds to facilitate the fracking process. Millions of gallons of water are used for a single well. This water is adulterated with the fracking fluids and is no longer a viable source of drinking water. Multiply this by the 1000's of wells being installed, and it becomes evident how much water is being lost in this process. The public has no idea what is at stake here, as the demand for water continues to grow while its availability shrinks.

Another important trend to watch is the purchase of public water supplies by private entities. It is likely that water rates will increase in areas where these diversions are occurring as the water resource becomes depleted.

Greedy villains? What planet are you on?

I'm not a greedy villain. I drive an old beater, am comfortable with the science behind climate change (got over that one in the mid-nineties), and give money to anyone who asks for it on the street if I have any.

I am reading the EPA report right now. It was prepared at a facility in my boyhood hometown. My dad used to work at that lab, as well as my best frien's dad and my scoutmaster. It is about twenty miles from the Arkoma Basin, which has been drilled like a pin cusion for shale gas. There have been no pollution problems that I am aware of in the Arkoma, but there were surely surface spills and that kind of stuff.

You guys just don't understand the first thing about geology, or at least petroleum geology (and all of the permeability and pressure analysis) and engineering of modern wellbore design. I haven't heard of a single problem in Oklahoma, but we aren't the biggest shale gas state. We do drill a lot of other zones horizontally now though.

I was in a meeting today. Part of it covered fracturing efficiency in the various lithofacies in this play, which is oil. Only idiots are drilling for gas right now. 99% of those shale gas wells aren't making their money back. They are just there to hold the leases and the reserves in the ground. When gas prices come up they will drill the increased density wells. Usually 6 to 8 per square mile, parallel. The fracture height and length is limited by physics, and those wells can only drain a couple of hundred feet around the wellbore in a 300 foot thick shale. These shales aren't just any shales, either. For a sedimentary basin to produce, you have to have an organic rich source rock, typically shales full of dead algae, bury it to a sufficient depth to reach a temp/pressure window to cook the carbon into oil and gas, and that rock sources billions of barrels and many trillions of cubic feet of gas.

In Oklahoma, the Devonian Woodford Shale is the source rock for almost all oil in the state. Oil and gas also migrated up into the TX Panhandle and the entire state of Kansas as well. You can type the oil back to that one rock layer, the Woodford. I could show you how to find the Woodford on a geophysical log in thirty seconds.

It covers vast areas, but there are only certain areas where it is in the optimum thermal maturity window to be full of gas. It isn't much of an oil shale like the Bakken in North Dakota because of lack of a really good natural fracture set, and the pore throat size barely allows a methane molecule to migrate to the induced fracture.

On top of the Woodford you have..Several hundred feet of Mississippian aged limestones that are also good horizontal targets. You have to stage frac the Miss as well. Above that lies the entire Pennsylvanian package, which is filled with porous zones that either contain hydrocarbons or saltw#ter. Then you have the Permian section which includes a thousand foot thick salt/anhydrite layer. 12,000 feet of rock above the targeted Woodford, which is maybe 150 to 400 feet thick.

So I am in this meeting and we were trying to figure out the optimal way to drill and treat this zone. A lot of science goes into a possible new play area. It is so intense.

You probably don't know about this, because the newspapers don't know jack, but we were checking out micro seismic data sets of horizontal frac jobs in this lithofacies group. Yep. You can lay out a geophone array just like shooting a 3D seismic cube, and rather than using vibe trucks as an energy source, you listen to the rock fracturing. It isn't like you could put a glass to your ear, lay it on the floor and hear it. This is sensitive stuff.

You see a 3D model of where the fractures are going. The entire point is to fracture the pay zone. If you get out of it, you are risking fracturing into an adjacent saltw#ter bearing formation and just getting a saltw#ter well. Otherwise known as a dry hole.

All but about 5 fractures stayed in zone, and the ones that didn't went maybe fifty feet outside into dense limestone. There were areas where the frac job was not efficiently fracturing the zone, and the chief engineer in the play was commenting on lots of technical stuff that will improve it. Another part of the play has a nice oil zone only fifty feet above another porous zone that is full of saltw#ter. That won't work with fracs. You will just frac down into the water and the water K being greater than oil K, you will just make saltw#ter.

I have been wondering if I could post a well log on here, from surface to the Woodford source rock, just to give you guys an idea of how many zones that you would have to frac through to reach the surface. Ain't gonna happen around here.

To all of you Appalachian people: The problem with the Marcellus is that there isn't a porous and permeable saltw#ter disposal zone in the basin. So what do you do with it?

Here is how a frac works. You drill and case the well. Now they are running two surface casing liners. One down to 2000 feet in many areas. 800 grand extra, but if it will make people sleep better at night..

After the well is drilled and the rig moves off, the frac crew shows up. Now even on a moderately sized normal old vertical frac this is an impressive array of equipment, but with the shale gas fracs it is HUGE. So the number of trucks will blow your mind. That, and they have to haul incredible amounts of clean fresh water via trucks.

So you frac a well. If it is a high permeability zone that didn't need a frac to open up low permeability rock, the shut in pressure on the wellhead would be zero. It is a lot of fluid, but a good porous sandstone can hold that volume in a forty acre area.

Shales were never considered to be proper reservoir rocks in almost all cases because permeability is in the nanodarcy range. It can take a full year for a methane molecule to migrate to a fracture. The pore throats are that tiny. When you frac a low perm rock, the wellhead will have fairly high pressure on it. You open it up and it flows the water back. Eventually the gas comes in and spits out the rest of the load. Doesn't take long. Days to a month in most cases. So you get that fluid back. Now it isn't nice clean fresh water with a drag reducer. It brings back water from the shale as well, and that usually has very high chlorides. At depth in a hydrocarbon basin, every pore is filled with saltw#ter, oil, or gas. Occasionally you will hit something weird like pure nitrogen.

So that used frac fluid comes back with crazy things, depending on the area. I know that there is a barium problem in the Marcellus. If you ran spent frac water through a municipal treatment plant that discharged into a river in Oklahoma, you would probably go to jail.

I read a story about how they were using the produced saltw#ter to de-ice roads in Pennsylvania once. Stupid.

In the producing states we have very strict rules about dealing with fluids. They aren't even hard to comply with. If the EPA suddenly gets into the exploration end of the oil and gas industry, we will be screwed. The state has a hundred years of experience dealing with it, and groundwater is nigh the only thing that they are rabid about. Depth to base of treatable water is known, and you are required to follow a strict set of operational guidelines. This is no big deal. We know the cost of drilling a well first. Then we look for reserves that will at least pay back the cost of the well. At 3.50 gas, very few of the current crop of shale gas wells are paying out. If you think the companies are greedy, just go buy some stock in one of the bigger domestic independents with lots of gas reserves.

I have tried to keep this within the realm of understanding, but the general consensus now is that the battle is lost. Not through science but through public belief. Kind of like the world ending in 2012, or Obama being a muslim born in Kenya, or whatever.

There are some really scary things going on in the arctic that nobody even notices.

As for the sudden industrialization of your countryside, dude from Appalachia, I know how it is. The Arkoma was pretty much drilled up within a few years. It seemed like 75% of the traffic was tank trucks. It has been pretty much developed and things are back to normal now.

It is dealing with the transport and proper disposal of the spent frac fluid that is the environmental problem. The aesthetic problem also can't be ignored.

edit: Yes, the amount of water is a big problem in the NE. It is no big deal down here. We have been frac'ing wells for 60 years or so. I guess the cities are used to selling fresh water. They charge a good fee and make $$ from it.

The industrialized part of it will die down. It is just a boom right now. If gas was ten bucks/mcf, there would be a lot more drilling. All of the gas rich independents are kind of hanging on by their fingernails right now. Go check stock charts on DVN, CHK, XTO, Newfield, etc. A lot of those wells cost 7 to 9 million to drill. They are lucky to pay out at these prices.

I have indeed seen my home town overrun with all of the tanker trucks. The trucks moving rigs, moving pipe, moving you name it. It was crazy. The Arkoma was like that for five years. Absolute mania. It seemed like every other vehicle was a big red tank truck moving water around. It has slowed down, though. Most of the drilling in the sweet area of the Woodford has been done.

I did however, want to clear this up. Most POTW's (Publicly Owned Treatment Works) that are large scale take in all manner of industrial chemicals so their acceptance of the fracking fluid is based upon the specific contaminants. FYI - I have seen Superfund Waste sent to POTW's (with banned pesticides) as well as wastewater generated from the destruction of nerve agents. Based upon my experience it is not inconceivable that Spent Fracing fluid could be sent to a POTW.

All they know is "journalism," which is important, but not a substitute for knowledge of the subject matter. In a way, it's like someone with a degree in education, but no science background, trying to teach physics or chemistry.

Unfortunately, none of us has the technical background in every subject of public interest, and we end up relying too much on those with journalism skills rather than on those who know. Our collective decisions often end up correct, but the discussion in getting there often resembles irrational babble -- or maybe just the ST forum.

You can't prevent it from contaminating the local well water.

But the fracking industry has gotten legislation pushed through that relieves the industry from liability for well water contamination.

After all, jobs are at stake!

What is surprising is that Republicans are leading the fracking industry cavalry charge. Historically Republicans have championed landowner rights. But now the Republicans are demanding that landowners forfeit their rights to their land and clean water in the name progress.

Historically Republicans have also championed local control. But now Republicans are calling for state and federal oversight to prevent local communities from regulating local fracking.

I wonder if this fracking contamination problem is somewhat limited to the Northeast and the Marcellus... It seems that many wells are located near or on people's properties, which might mess with their drinking water more-so than say somewhere in Oklahoma.

There's plenty of fracking all over the US. Just seems that most of the water contamination complaints are coming from Pennsylvania, where lots of people live very close to fracked wells. It doesn't seem like there are many complaints in the Dakotas, where there are like 150+ drilling rigs fracking like crazy...

So does that make it safe if it's far away from civilization?

I'm not stupid. Although I would prefer a full-on push for non-fossil fuels, the reality is that I'm stuck putting gasoline into my car and heating my home with natural gas.

So I'm not opposed to coal mines or fracking or whatever -- but I am vehemently opposed to the manner in which it is curremtly being conducted.

Under GWB, there was a ruling that filling river vallies with debris from strip mines did not require an environmental impact statement. So now the mining companies are stripping off mountain tops and dumping the material into river basins. Then they abandon the strip mines without reclaiming the land, and leave it up to the state to clean up the mess using levies collected from each ton of coal. But the levies are so small that the clean-up efforts are less than 50% funded.

Now with fracking - contaminated water, trampling of landowner rights, speeding trucks - it's a mess.

We do have a few large wind farms here in WV. Apparently the largest wind farm was put up in a major bird migratory path and a major bat area. The bird and bat kills from the turbines exceed the usual kill rates associated with other wind farms by an order of magnitude.

This is what our creeks are like around here. The Cheat River is a major river that, until recently, was completely dead. Thanks to groups like the Friends of the Cheat and West Virginia Rivers Coalition, there is a lot of work being done to buffer the acid mine drainage before it reaches major waterways. Usually the buffering is done with limestone and precipitating catchment ponds. It's all being done with private funds because the state can't afford to reclaim abandoned mines.

So it's really a manner of conduct.

Yes, the Marcellus is a unique animal in many respects.

In most basins disposing of saltw#ter that is produced along with oil and gas in the normal production process is separated at the tank battery. Nothing fancy there. It is collected and hauled to either commercial disposal wells, or onsite disposal wells, all of which are tightly regulated by state regs. Those wells are tested every year for casing integrity via a mechanical integrity test (MIT) where you set a plug above the injection zone and then pressure up the casing to check for leaks. If the pressure doesn't hold, it means you have a casing leak.

The disposal zones vary, but all are deep and full of saltw#ter. The fresh water table is shallow and easily mapped.

The big disposal zone in the midcontinent is the cambro ordovician Arbuckle/Ellenburger group, a massive limestone that is both very porous and very permeable. It is also very thick, so it is nigh impossible to pressure it up from injection.

Old frac load water is injected along with the saltw#ter, and trust me, the saltw#ter is way more nasty than the frac water when you are talking about those shale gas fracs.

It is a really easy way to get rid of that water. The Marcellus, from my reading, is unfortunate geologically. There is no good deep zone to put the salt water or frac waste water into. This has lead to all kinds of crazy things like recyling and treating.

Saltw#ter disposal isn't that big of a deal in most areas, and the same goes with spent frac water. The well flows that frac water back and then becomes a gas well, ya know.

As for the shitty comments like Republicans like this. Yeah, they like it because they don't give a crap about the environment if you are a Limbaugh head. I am a democrat with a very deep and cynical distrust of the Right Wing in this country. The Right has moved so far to the right that they are no longer in the visible spectrum. Most of you don't know me, but I have spent as much of my life as possible outside, and am really rabid about ANWR. Because I have BEEN there. Four times. I spent a whole summer in there walking across it and back alone. I have crossed the coastal plain 8 times or something now. Incredible place.

And my hometown gets its water from a huge spring from the Arbuckle Limestone, about ten miles from some of the biggest Arbuckle disposal wells in that part of the state. Great water. Now that water supply is in great danger because the suburbs of Oklahoma City have been buying up water rights in the aquifer and are going to pump it and send it to OKC. Hey, it is great water, but when you lower the water table, all of those great springs are gonna go dry. Then we will have to drill our own wells back home. It all has to do with withdrawal and recharge rate, and I am not a hydrologist.

So yeah, I drink the water like a fish. My parents still live there along with half of my friends. It is only an hour away. It is beautiful hilly and forested country.

We just haven't had the problems that the hysteria spouts. Mainly because the hysteria is 90% bullsh#t, and the 10% that isn't bullshit is so poorly understood. I just want to toss up my hands and shake my head.

Remember the BP Macondo blowout? After about a week the main description of how the blowout occurred became pretty widely known in the industry. BP was insanely negligent IMO and many others. BP is not liked in the industry.

Well, there were all of these experts on the news channels. They were all bright guys from Universities and stuff, but it was obvious that most didn't have much of a practical background. I saw a long lecture on the web with a guy from some university describing the horrors of frac jobs.

They mispronounce words and pull things out of their ass.

So I am sitting there watching this blowout play for weeks and pulling my hair out at the insane garbage I was hearing. That well should have NEVER blown out. It was already drilled and was being plugged before moving the drilling rig off and putting a production platform in. Which might take years.

Look. Pretty much any petroleum geologist will tell you that we need to get off of oil from just a strategic and economic reason. Plenty believe in climate change. It isn't like you get fired over it.

Most of our electricity comes from coal. Even in Texas. Coal is a cheaper and more efficient fuel, but it is nasty stuff. Meanwhile we swim in so much natural gas that the price is where it was in the nineties.

Switch to natural gas. Then switch to something cleaner. Biofuels and all of that is bullsh#t. You are still burning something and tossing carbon into the atmosphere.

Look. People cry wolf. No way would an entire company do this. The big independents all have huge environmental compliance departments just to avoid screwups.

The Marcellus problem is not directly related to the frac process. It is indirect. No place to put the water. One of my clients is big into acquisitions. They won't touch anything in the Marcellus.

I wish that I could give a two week lecture and field trip to you guys.

Clean groundwater is huge. All that is happening is that the EPA is going to jump down throats over something that is not a problem in the rest of the country.

It seems all I do is answer frac questions anymore. Geez. Didn't anyone notice that Obama opened up the offshore Beafort and Chukchi Seas for leasing and exploration? The Beaufort federal leases start three miles off the north coast of Alaska. That would be three miles off the coast of ANWR, where it is covered with moving ice 9 months or so out of the year. Nobody seemed to notice that.

I see how easily people are manipulated from watching and listening to news coverage of this and the Macondo blowout. All of the talking heads were lost with their heads up their ass on the BP blowout. It was a very simple thing on that blowout. Everyone in the industry knew what happened. All of the "experts" on TV kept getting it wrong.

It made me sick to my stomach. All of this safe deepwater drilling was ruined because BP cut a couple of critical corners and made a few huge engineering errors. That blowout should have never happened. The well had been drilled and cased for production. Worse, it was oil. Oil is heavy and flows with less pressure than gas. I hadn't seen an oil blowout in the U.S. in ages.

So you can get the Marcellus straightened out or go remove hillsides and burn coal til the end of time.

Also, the next time you fill up your tank, squirt a gallon of gas over your head. The nasty end of oil and gas is the exhaust pipe. It isn't totally snow white on the land Exploration end, but in the sceme of things, it isn't much. Problems with fracs are very rare. I know how they can go wrong, and it usually means that you lost your well or you had a surface spill. The idea that it is plumes of poison migrating to the surface through blasted rock is not how the problems happen.

I have no axe to grind. I am not even in the unconventional reservoir business. I do work with horizontal wells in conventional oil and gas reservoirs, though.

For something nasty, go look at a gas station with leaky underground tanks. Or a dry cleaner. Or an air force base that has been dumping its solvents down the drain for the past fifty years. I get to hear an earful over that. My wife is a big honcho at the state DEQ. I have a bunch of friends up there. We talk about this all of the time.

Those wells will be depleted and plugged in twenty years. You won't even be able to see where they were except bulldozed roads through timber and pipeline right of ways. Those mountain tops don't grow back.

Coal is nasty stuff. You won't find a petroleum geologist on the planet who likes coal. It is the most carbon intensive fuel of all. Natural gas is the least. Still bad enough for the atmosphere though.

This is like an argument between a coca farmer in Peru and a drug addict in Los Angeles.

Most of the guys I went to school with are groundwater guys. I know a bunch of other guys who do nothing but Superfund work, including my wife.

I have been listening to my wife and her buds for twenty years. She used to run the state's end of all of Superfund. So I get to hear about some super nasty stuff. Dealing with the Corps and the EPA. The EPA does things that just don't make sense sometimes. Literally, not politically.

Hydrology is similar to petroleum geology. Permeability and fluid flow in porous media. We just deal with super high pressures and a lot of petrophysics. I could teach you the petroleum end in a year. You seem a smart guy. We deal with millidarcies, though. Those shales have nanodarcies of permeability, hence the big fracs.

I get called in to work difficult clastic and carbonate stratigraphy. I do cross sections and reservoir characterization over a hundred miles long every day. It is a lot of fun, but very difficult.

People just don't understand how oil or gas gets into the groundwater. Sometimes it is totally natural. Those are really obvious spots, though. Super shallow oil and gas. That EPA study was in a very shallow gas field where there were gas zones in the fresh water. I can show you oil at 70 feet. Totally natural. Weird stuff. That EPA study was in the Wind River basin. Man. Ground water flow in mountain basins is super active.

The most common oilfield pollution is saltw#ter in the groundwater. You can't clean that up. The groundwater is trashed. A surface saltw#ter spill is awful as well. Chlorides get into the clay minerals and nothing will grow for decades.

Being greedy is where you cross a moral line for money. I am pretty comfortable with frac jobs. I am just not so sure about the Marcellus. So many chances for error trucking all of that water around. Not to mention the million pounds of sand.

One thing about oil and gas companies. They have little muscle politically. The de facto national energy policy has been cheap oil at any cost since Reagan. That puts companies into bankruptcy. The domestic industry can't compete with Saudi Arabia when it comes to setting oil prices. Sure we benefit when prices are high. We also bleed when they dump oil and prices crater. You can take every private oil company in the world, add them up and they are a flea on the ass of the nationalized companies in the big exporting countries.

I can't stand those Exxon commercials where the nice guy comes on and sweet talks shale gas. It is just propaganda, true or not. Exxon is a micro player in the shale gas plays. It is dominated by the big domestic companies. You can't go make a dump like they do in Nigeria or some place.

I desperately would like the world to move beyond hydrocarbons. People bitch and moan, but they still buy SUV's and big trucks that they don't need. We burn oil like it is water.

edit: Why do you think we have our fingers up the nose of every country in the middle east? Why do we have all of these Nimitz class aircraft carriers hanging out down there? It ain't because we like sand.

That end of it is kind of like blood diamonds. Nobody gives it a thought when they fill up their tank. They just want it cheap.

No. The real one was K. 3% KCl water is a pretty common frac fluid. Benzene was from the old days. Benzene is a common component of crude oil or gas condensate. I just need to go through the report and finish it up. I know one thing. They don't know how to read a cement bond log. This field has been drilled in since the fifties, and in the fifties, groundwater issues weren't as strict as they are today.

They frac'd a shallow zone and it got into one of the wellbores drilled back in the fifties with poor surface casing, it seems. The field is incredibly shallow, and the fresh water very deep.

The EPA had to really scour the earth to find that one. Those are called "Black Swans."

I have been saying this over and over again. A wellbore is the conduit to groundwater, not some mysterious fracturing of 10,000 feet of overlying rock.

Southern Oklahoma has a big field called the Allen District. It has fresh water down to about 100 feet. There is a gas zone at 300 feet, and oil at 500 feet to about 2200. These are all shallow. Anything under 1000 is super shallow. There may be a hundred wells in a square mile. There are waterfloods with old uncased wellbores. I can't believe it, but they haven't had contamination. Fracs aren't that useful at such shallow depths. You really have to overpressure the formation for it to work.

This is totally unlike 99.9% of modern production. Mainly because shallow zones have low pressure and poor reserves.

Where things get really trashed is if you waterflood a zone like that with old, poorly cased wellbores. You really pressure up a waterflood, and it can migrate into an old wellbore and straight up into the groundwater. There are huge areas of chloride contamination in the groundwater from old waterfloods, but they all involve old wells. It just isn't done that way now. It happened in the old days, though, and there a fair number of big chloride contaminated fresh water aquifers. It is almost all historic.

To get a waterflood permit these days, you have to re-enter every old wellbore and fill them with cement. You also install monitoring wells if you are smart. The OCC won't permit a waterflood in those instances. A permit takes ages, and is gone over by hydrologists and petroleum engineers working for the state. They know how to spot a bad idea.

The EPA case is totally unlike the shale gas fracs. Those are at great depth and have multiple surface casing strings that cover way more than the fresh water table.

The Powder River basin saw a coalbed methane boom about ten years ago. They drilled into those massive Fort Union coals and produced gas. The interesting thing was that it was up in the fresh water table. The coals weren't even that far downdip from the strip mines.

The wells were small, but you could drill them in five hours with an air rig. The big boys stayed out of it. Not enough reserves for them to turn their spotlight on it.

Maybe someone here can enlighten us, but I am not sure what became of that. A lot of the water was being used in farming, but coal has some nasty stuff in it, like mercury in some places. So just letting it go on the surface is probably not a good idea. Drinking it in the first place sounds kind of spooky to me.

Want to hear a really good groundwater case? A fairly common one now?

I live on the Garber/Wellington aquifer. The water isn't that great. It has high arsenic and other nasties in it. So the city blends the good wells with lake water to bring everything down to EPA limits. It is a huge aquifer, though, and very important economically.

About five miles south of my house there is a big area that is heavily contaminated with nitrates from agriculture fertilizer. It is OK to drink if you aren't pregnant. The word got out around fifteen years ago not to drink the water if you are pregnant. I am pretty sure that they tied in to the Norman water system and don't use much well water in that area.

I need to finish the EPA report. I am about halfway through it but am trying to work if you would quit calling me a liar. That is the problem with getting into a bitch session on this place.

I have enough of a groundwater background that I spent some time during the last price bust on test wells for a landfill. I got a lot of help from my friends at the state DEQ. I didn't like it. I don't think the permit passed.

That overlying sal-tw#t-er is presumably in a relatively permeable unit, no? That sal-tw#t-er is more dense than the underlying petroleum, no? And it is separated by the confining layer/trap, no? Connect the two via an unintended fracture through the impermeable layer and the sal-tw#t-er will flow down while the petroleum flows up, no?

I don't know if those fractures penetrate the cap rock... and I don't think the oil companies/hydrofrac'ers do either. I'm not saying it is currently an issue, I'm saying it may be an issue... one I seriously doubt oil companies spend much time contemplating... other than what will happen if brine enters their reservoir, in which case they shut it down and walk away... out of site, out of mind. But the buoyancy forces persist...

No. The overlying rocks are interbedded shale, sandstone, and limestone formations. They all have names, and I know most of them. You need to understand that at these pressures many of the rocks have a plastic quality. If you put some fractures up into a saltw#ter zone, you better pray that it doesn't connect to the shale target. If it does, you will get a saltw#ter well. Besides, those zones also produce in areas and they take their own frac just to increase perm and produce.

I'm not sure where you are going with buoyancy. Water is heavier than both oil and gas. That is the main way oil and gas accumulations trap. They float on water and migrate towards the surface until they hit a barrier and stop, creating the accumulation.

The tar sands in Canada are just a huge oil field that has eroded and all of the volatiles have escaped. That stuff is pretty nasty. About as bad as coal, but you can't put coal in your gas tank.

edit: I see where you are going at with buoyancy. See above. All oil and gas basins have hydrocarbon traps. It is a miracle that the stuff has so few surface seeps. Just go get a book on petroleum geology at the used bookstore. The migration and trapping of hydrocarbons is extremely well understood. That is what we do. Look for those traps where oil and gas were prevented from migrating higher.

Most shales are very clay rich, and that stuff is a really good trap and seal. The Devonian source rock shales don't really frac well unless there is a high silica content. I was amazed at how much silica is in those shales.

Then you have a thousand feet of evaporites sealing most of the basins around here. The best hydrocarbon basins have evaporite seals. Salt or anhydrite.

Wes,

Sorry. I shouldn't have said that liar bit. I know you aren't accusing me of that. I just get pooped about going through petroleum engineering 101 over and over again.

When I tell people that I am a petroleum geologist, I have to go over the frac thing all the time, and it gets tiresome.

I didn't have time to finish the EPA report. Hopefully I will have some time to finish it and then get back rather than letting this thread die.

A short answer to one of your questions about frac'ing zones with offsetting wells having insufficient surface casing, it is not common, but it is done. The shale gas monster fracs are nothing at all like this.

One funny thing. Even before Drake's famous first oil well, there were some places, I think in New Jersey, where the Marcellus outcrops, and it was common to drill super shallow wells, less than 100 feet, to provide gas for heating.

Gas isn't a very good shallow target. With gas, reservoir pressure equates to more reserves. At a shallow depth the reserves for gas are small. This area has gas at very shallow depth.

Believe it or not, there have been more fracs in oil wells than gas wells. Permeability is usually related to pore throat diameter, and methane can produce naturally in lots of low perm reservoir rocks. The relative permeability of thick old oil is less. So oil reservoirs are more affected by low permeability.

These shales also have vast areas where the thermal maturity window is in the less cooked oil window. Oil molecules are just too small to make it through almost all shale pore throats. The obvious exception is the Bakken in North Dakota. It is a different animal.

Again, typically the sedimentary section is 90% shale anyway. The gas and oil shales are very specific zones. They are very specific. These shales are the organic rich source shales. They may be only a couple of hundred feet thick, but they have sourced trillions of cubic feet of gas and billions of barrels of oil. You can't target just any shale. It is almost all Devonian source rocks in Paleozoic basins.

And the EPA did have to scour to find that specific field. It is very unusual in the fact that there are very shallow gas zones that lie within the deep fresh water table. This is really uncommon, but not unheard of. This is in no way close to the geology in the shale gas frac areas. Those zones are deep.

I will try to get back on this. I certainly didn't intend for it to die without answering you. I am just soooo busy.

I do have an email circulated through a lot of the geoscience community about the EPA study outlining the nuts and bolts. Since it came from the oil and gas sector, I haven't posted it. There is propaganda from both sides on controversial issues. The guy who wrote the response is quite the stud, but I want to go over the EPA report several times.

I'm not dimissing the EPA report at all. I am just saying that from a geology standpoint, it is unusual.

A mine is a hole in the ground with a big pile of rocks next to it. Unfortunately, those rocks are from very deep and have not been through the weathering process. So they get chemically weathered and spit out all kinds of stuff.

I have nothing against mining, but that mountain top removal looks totally insane. It isn't like they are gonna haul all of that rock up and rebuild the mountain, correct?

I had knee surgery yesterday morning so my judgement is a little off for the next few days.

As for the new Pavillion data, you knew a response was coming. EPA certainly could have done a better job, but it doesn't mean that if they resample that they won't find the same things. You have to watch anyone who has a dog in the hunt.

It will get sorted out, but their deep wells were within the shallowest gas zones. I know that much. There is a problem with blowouts in the deeper stock wells. Typically livestock water can have higher chlorides than a human source by quite a bit. As you go deeper you get out of the fresh water and it is all saltw#ter from there on down other than a few kind of exotic locations.

It doesn't take much to blow out a well that isn't keeping the hole filled with heavy drilling mud. I know of quite a few areas with that problem. It usually means that the accumulation has unusually high pressure.

Finding stuff in the gas zones isn't that strange. If they find it in the shallow low chloride human use aquifer, it is a big deal. Still, that field is not in any way the normal type of field. So shallow and stock quality water at that depth.

Peak oil, not a concept, but likely reality. It seems to have arrived sometime in the last 6 or 7 years. One factor that bears thinking about is how good we are at exploiting and accelerating production in existing fields due to horizontal drilling and waterflooding. Once these fields start to go they will crater very quickly.

Thanks, Wes and BASE, for an informative discussion. As Wes knows, my daughter's best friend in college is a graduate student in hydrology, and I've used some of her input in my work on attempting to measure marginal costs and benefits in carbon emission regulation. What I always find intersting is discussion among people particularly versed in different disciplines, but examining the same phenomena.


When I compare your discussions with the more simplistic and either alarmist or nihlist approaches of so many others on this topic, it makes me appreciate all the more the thought you two put into a discussion that, as wes would say, is only on the taco stand.

Peak oil is just a catchy phrase for a simple topic:

When will the world's production rate peak and then start to decline?

Most of us think it has already happened.

You just look back at Hubbert's work on U.S. oil production. Everyone thought that we were finding plenty of new fields and would have excess production capacity for decades into the future. He nailed it within a few years.

It is more complicated with worldwide production capacity, given that remaining reserves in the largest and most important fields are state secrets. The biggest fields in Saudi Arabia have been on enhanced recovery for some time.

It is only important if you figure in production capacity vs. demand. Oil is like air. You can't invent new reserves. You can change demand very easily. Carter took us from 20+ million bbls/day of consumption down to 15+ in only a few years during the seventies oil shock. All it takes is a little fine tuning of bad habits to cut demand.

So you see that the equation can be managed on the demand end. We should have been keeping it up since Carter, but oil prices collapsed and we have enjoyed incredibly cheap gasoline until the past few years.

We just waste it. Hell, why not go buy an SUV? Everyone likes to point fingers at oil companies, but nobody likes to look in the mirror.

I can rant on this for days. We go spend our money on stupid wars in oil producing areas instead of building light rail and other wise infrastructure investments for the inevetible future of high energy prices.

Face it. We are stupid.

Since I am laying on the sofa gulping pain meds from my knee surgery I will go a little further.

We have had a very well defined national energy policy since Reagan: cheap oil at any cost.

I never can see how so many oil people are parrot talking conservatives. When oil prices went to ten bucks a bbl under Reagan, it was bloodshed in the industry. Total collapse. You couldn't get a job unless your daddy owned an oil company.

Now prices are rising as expected, to my long hoped for dream of 100 bucks a bbl. The only pain in the ass is that a well may cost 4 million bucks for the same recovery as a well that cost 500 grand twenty years ago.

Oil companies have zero control over price. It has always been that way. The big exporting nations control the majority of reserves, and all the Saudis had to do in the eighties was open the spigot. Took down the Soviet Union. Took down much of our domestic industry along with it.

Natural gas is plentiful. It sells for what it did twenty years ago. All of those shale gas plays haven't come close to being fully developed. Natural gas has the lowest carbon footprint of any fossil fuel, it is cheap as hell. We should have been converting to natural gas as a transportation fuel a long time ago. It is in our strategic interest as well as the health of the planet. Switch trucking over to nat gas now.

The only problem is that you have to refill more often with natural gas, so it is less convenient. It can be a bridge fuel to clean technology and a much more efficient transportation infrastructure.

Save oil for making things out of. Hell, morphiene is made out of oil now.

Use it for those certain circumstances where you need the incredible energy density of a cup of oil. Airplanes and the like.

Iran looks like it has passed its production peak. There are massive gas fields in the middle east with no market. A truly massive one is in Iran. So they are doing the smart thing: Convert to natural gas as a transportation fuel and sell the oil for the country's income.

By trashing Iraq, the country who kept Iran busy as an enemy, we now have a pro iran government in Iraq. Iraq was always vastly underexplored. More than any other Arab country. So Iran just de facto more than doubled its oil reserves and is the big powerhouse in the middle east.

Happily, when they run out in the next couple of decades, they have no industry to take over and will go back to camels.

People are only going to conserve energy when it gets really expensive. Trust me. No matter how good people we think we are, we are not altruists.

So yeah, "Peak Oil" is plain as day. Nobody seems to care if they can fill their tank tomorrow. We are incapable of thinking past the two year congressional election cycle. This country can no longer think ahead. Politics is that f*#ked up.

I'm also aware that, to the best of your knowledge, hydrofracers take every necessary precaution to prevent any contamination... but we are both aware that people cut corners and accidents happen (BP via Halliburton).


Yeah, it's like saying most congressmen are good god fearing people so reports of gay GOP congressmen tapping their feet in men's restrooms are likely BS!

Cause somehow or another, the pollution somehow associated with fracking is hitting people's water and we've heard enough from intelligent industry turning out to be untrue that nobody is buying the "Don't worry, we're careful and know what we're doing" assurances. I'm sure the folks at Fukushima were total experts and had lots of money and expertise behind them

Fracking is here to stay cause of peak oil, which is MAJOR. Yes demand can be cut for short time but don't forget that China has trillions in surplus and wants to develop and india is in line behind them not to mention the rest of the third world would prefer to move up to second world

Sad to say, but the same forces will demand we drill ANWAR. The only question is whether it takes $7 a gallon gas or $13 a gallon.

Says you with nothing to back it up. The Saudis officially announced they would be keeping the price of oil at $25 for decades but were able to do no such thing, even with Bush begging and kissing them for more production, lower prices

from 2008
http://www.time.com/time/world/article/0,8599,1715308,00.html

Racing between OPEC meetings in Vienna, Saudi Arabia's powerful oil minister Ali Al-Naimi told a reporter that the cartel was "determined" to keep the price of oil at around $25 a barrel, rather than risk a slump in the market by boosting its production.
Wait a minute. $25? Al-Naimi said that in April 2003 — less than five years ago — when a barrel of oil cost one-quarter of this week's whopping $100, and when prices were regarded as high enough to keep oil-rich countries happy......
In fact they said that back as far as 2001 as well

From 2001
http://www.albawaba.com/business/saudi-opec-wants-oil-price-25


Saudi Arabia oil minister Ali al-Nuaimi said Saturday that OPEC wanted the price of oil to be $25 a barrel, avoiding brutal swings either up or down.



"We (OPEC) want it to be at $25, rather than $30 or $38," he said at a seminar at the annual meeting of the World Economic Forum. Crude oil prices are currently around $25 or $26 a barrel.



"Our revenues come from oil and we need to make an accurate assumption of what the oil price will be," he said.



"I am sure that if the oil price should go up or down in a precipitous manner we will work together for a stable oil market," he added.



Al-Naimi said that the recent decision by the Organization of Petroleum Exporting Countries to cut oil production was taken to prevent a freefall in price and "keep it towards the $25 per-barrel target."


They sure are taking there time stabilizing the old oil market. Didn't seem to pick up much slack when Libya went offline.

OF course you can't be faulted for not knowing whether the Saudi have excess capacity or not because it's a deep secret that nobody knows. The ones with some personal experience say that's it's twilight time on saudi oil abundance

He uncovers a story about Saudi Arabia’s troubled oil industry, not to mention its political and societal instability, which differs sharply from the globally accepted Saudi version. It’s a story that is provocative and disturbing, based on undeniable facts, but until now never told in its entirety.

Karl,

I was insulting to you, and I apologize for that. That is not my nature.

The Saudis are saying the same thing about 100 dollar oil.

I am downloading about 200,000 wells right now just to show you some maps of how many shale gas wells have been drilled in some basins I work. I don't know of any groundwater pollution problems in these areas. I would probably have heard about it.

The big drillers like Chesapeake have huge environmental compliance departments. One screw up is a huge disaster for companies like them. I have consulted for them, and they are dead serious about that. They had a spill on a Marcellus well and the moon suit guys are on a jet in a couple of hours to take care of it.

Halliburton, no matter how evil they are overseas, is the gold standard in well completions. The Macondo blowout had nothing to do with Halliburton. BP was utterly negligent. They make me sick. Nobody likes BP.

Arkoma Basin Woodford Shale. This one has been going on for years. I grew up here and it still is pretty country. The bad thing is all of the roads that were put in for the wells. When the wells are plugged the location is cleaned up, topsoil is replaced and you can't spot where they are without a stout metal detector.

There are 46,000 wells in this dataset, but if I print the whole basin it just looks like a buckshot pattern. The lines are the horizontal paths. Depth to zone here is 8,000 to 10,000 feet. The Woodford is a few hundred feet thick.

This is a horizontal play targeting a low perm sandstone oil reservoir. Each square in these maps is a square mile.

Sorry. I didn't have time to download the landgrid overlay on the Texas Panhandle side to the west.

Every well on the map has been frac'd going back to lord knows how long ago. The horizontal play has been going on here for over five years. This one is beneath the Ogallala Aquifer. No problems I have heard of. This is all farmland.

OK. Fracs are nothing new. I don't know how many tens of thousands of these types of wells have been drilled now.

Sorry. I don't have Marcellus data. I just log on to the data server and download the well locations. No secret here. This is all public data, but it is easier to see when run through professional mapping software.

I could do this for the next week.

I live in NY and follow the fracking issue very closely, including most reports, news articles, studies, what the EPA has done, what the NY DEC has done, what's gone on in PA and the PA DEP, etc. I've been to multiple frack sites in PA, talked and met with a number of families in both PA and NY who are victims of fracking contamination (in NY vertical fracking), met with industry folks and countless environmental and advocacy leaders, and heard hours of testimony from experts on both sides of the issue. At this point there is an enormous amount of misinformation out there about fracking. With that, let me put out just a few things to consider, the bottom line being that fracking as it is going forward right now is a desperate form of fossil fuel extraction, that holistically is similarly bad as coal for the climate given the amount of methane released into the atmosphere (methane being a particularly heavy greenhouse gas). Although fracking has in some capacity been happening since the 1800s, the fracking that is going on now is not like the fracking back then, the fracking in the 40s, the fracking in the 80s, or even the fracking in the 90s. It's a new technology. There is no good evidence that this fracking can be done safely, and there is a very strong case to be made that fracking should not go forward now or any time soon, especially in the northeast.

Some of the many points that are sorely lacking here:

 Official review and regulations of this industry are extraordinarily limited given that it is exempt from the Clean Drinking Water Act, the Clean Water Act, the Clean Air Act, and the Superfund Act.

 There is a tremendous amount of evidence linking fracking to well over a thousand cases of water contamination. You don't hear about these and they don't get documented because most of these cases are between relatively poor landowners and the gas industry, and those landowners make a legal settlement with the industry or face over a decade long legal battle. Obviously, pretty much no one who would lease their land for fracking can undertake such a legal battle, and hence settle. Those settlements include non-disclosure agreements, i.e., legal gag orders that prevent those people from speaking out and prevent the EPA or other agencies from pursuing study of those cases.

 Yes there are many well casings and it is far down, but over time methane and other (worse) chemicals can naturally travel up to our groundwater and the surface outside of the outer-most casing. You could have 50 layers of casings, but that doesn't seal the space between the outer layer and the dirt that is on the outside of the hole you drill into the ground. And remember, the frack itself, a mile or more underground as it may be, blasts holes in the casing as is necessary to pull out the gas.

 Here’s just one example of the technology that is being touted as so great and safe. With extreme pressure used to blast millions of gallons of water thousands of feet underground—enough pressure to push open rock fractures—an enormous amount of faith is put into a one piece of technology called the “blowout preventer.” You'll recall this from the BP oil spill in the Gulf of Mexico - it blew out and we all know the rest of that story. The primary company that makes these devices, Cameron International, is considered the gold standard. By Cameron International's own field test results in the wake of the Gulf spill, they reported that their blowout preventers fail 62 out of every 90,000 uses. Doesn't sound like a lot but with the number of wells planned in NY, we'd be looking at well over 60 disasters in NY from that problem alone. Cement casings themselves have much worse rates of failure.

 There is no impressive rapid response to problems. There are two companies that can deal with real disasters such as blowouts: Boots and Coots, and Wild Well Control, both from Texas and with names that suggest a cowboy mentality that presumes this destruction is just a wild ride. When we had a massive well blowout in PA, Chesapeake Energy had to fly them in from Texas, meaning it was more than 12 hours before anyone was even on the ground who had any idea what to do, as it would always be.

 Every stage of the fracking operation releases known and suggested human carcinogens and volatile organic compounds such as benzene (from the wellheads themselves and formaldehyde (from compressor station engines) that are closely linked to various forms of cancer, asthma, respiratory illnesses, destroy air quality, etc. There are serious concerns to prenatal health, brain development, and countless diseases and health conditions.

 The justification for fracking is of course money, primarily jobs. The job creation claims are vastly overstated, and are almost always numbers of "new hires" not net jobs (meaning two people hired on the same day that two people get fired still means two jobs get counted as created). Hand in hand come significant losses to other industries including agriculture, small businesses, tourism, housing values, etc. Furthermore, communities suffer from increased crime rates, transient workers, damage to local infrastructure such as roads and bridges, increased strain on emergency workers, and the burden of having a heavy industrial operation literally in people's backyards. Also in NY for instance, all estimates and projections for economic benefits are currently based on an estimate of accessible gas that is over 400% greater than what the USGS believes is there. Whoops.

 We need energy but we have plenty of natural gas in the US right now. The main draw to increasing fracking is to ship it overseas where it is worth generally at least 3 times as much, hence why we are seeing more and more plans for liquefied petroleum gas facilities being built. We should be investing in renewable energy sources, energy conservation, and a smart grid. Doing so would create more jobs and a far better economic boost for regions where gas drilling would otherwise come in.

Base,

Do you know anything about the gas geysers that were coming to the surface out around Okarche, OK and Kingfisher, OK? I hadn't heard anything about it in a long time. Early speculation was blaming it on a well being drilled by Okarche. There was some fear of it contaminating the ground water. There seemed to be a media blackout of it so I never heard anything more about it, just tidbits that I would hear from my friends in the oil industry.

Fructose, for some time I've been doing environmental work, organizing around various environmental issues. Early in 2011 I left a different job to focus on fracking in NY with Frack Action as it became apparent to me that NY would be terribly mistaken to go down a path of fracking as PA has done. As for Gasland, I think it is effective in getting across many of the significant concerns and yes, even facts, about fracking. At this point it is pretty outdated, given how much new information we learn about fracking each week. Nevertheless, most of what is presented in Gasland is fair, as many analyses have found. The gas industry did put together a smear campaign in an effort to discredit it. Of course it is a documentary, and being limited by the time appropriate for a movie and factoring in a story, it doesn't go into as great detail on every point as possible.

FortMental, I'm not Claire but I work with her and I think I copied two sentences or so - standard points that we bring up as they are rarely realized - from a reference doc that was probably used in that Assembly testimony. If you look more closely, you'll see that I just wrote 95% of my post...just not the one or two lines re stats that I always look up in order to make sure that I not get my numbers wrong.

Oh,man.

I haven't heard about gas geysers near Okarche, but I can guess. Back in the mid nineties there was a well being drilled down in the SW part of the Anadarko Basin. They were drilling through a high pressure deep gas zone and gas got into the groundwater. In that area there had been a bunch of seismic exploration going back to the old days and the old shot holes all started spewing saltw#ter around the rig.

The old shot holes were for dynamite shots, and about a hundred feet or so deep. These days almost all seismic is done with vibrators. You get a full frequency sweep with those.

You aren't going to get a true blowout from a shale. The permeability is so low that you can perforate that zone and nothing will come out of it. The problem around Okarche, which is actually on one of those maps I posted is that the Woodford is beneath the Springer sandstone series, and the Springer is overpressured gas. So you have to run an extra intermediate casing string in that area. That would be the map of the Cana area that has a zillion vertical gas wells (red star symbols) in it.

There was a Continental Resources well that blew out around there late last summer. Rig burned, the whole bit. That is really rare any more. Pressure control is a pretty refined art now.

If anyone was going to drill on my land, CHK would be at the top of my list. They have a massive environmental compliance division. HFCS could probably get a job with them for huge bucks. They are super serious about everything. One black eye for CHK just isn't worth it. I will post on what happened on the CHK spill last year if anyone wants a pressure lesson on fracs.

As to the list of stuff Alpine Thrills posted, there is a kernel of truth buried in many of the statements, but they are insanely exaggerated. That is the way it is if you have an agenda. You take a kernel of truth and then build a big house of bullshit around it. Oil companies do the same thing. I saw a BP commercial the other night and it made me ill.

I should go work with one of the anti frac'ing outfits just to nab their heads, hold on tight, and point them in the direction where the real environmental risks are.

OK.

First, why do some reservoir rocks need a frac and others do not?

Permeability of the reservoir rock.

Shales have such low permeability that it can take a year for a methane molecule to migrate five feet towards an induced fracture and make it up the wellbore. These shales are only prospective where they are in the gas thermal maturation window. If it hasn't been cooked to a high enough temperature in the past, it will be oil or heavier gas liquids. They can't make it through a lot of shale reservoirs simply because the molecular diameter is too big to make it through the incredibly small pore throats in the shales.

Shales have such low permeability that they were not even considered to be a target, although it has been known for decades that the mainly devonian shales are the very rocks that source all of the conventional vertical oil and gas wells of entire sedimentary basins. You would drill through the Woodford and get a great gas show on the gas detector present on drilling rigs to look for "shows" of oil and gas.

Many productive basins produce both oil and gas, and they trap in the same way. The hydrocarbons in the basin was in most instances entirely or primarily from these carbon rich shales. Not just any shale will do. They are specific and piss easy to identify and map. That said, there are fairways in all of these plays where the wells are better, mainly due to the physics of the rock. They need to be brittle, and this means a high silica (sand, but very small particles) that will actually fracture.

There are many high permeability zones that do not need a fracture stimulation to produce economically. You drill to the target, hope you hit it, and then simply perforate the casing over the zone and produce the oil or gas. The wells deplete over time, some quite quickly, and eventually the reservoir pressure is so low that the well cannot produce in sufficient quantities and is plugged. Plugging is highly regulated by the producing states, although if you go back to the fifties and sixties, the casing and plugging requirements were poor. That is the primary pathway where subsurface gas can make it to the surface: Old Wells. The regulatory infrastructure in the big producing states are super strict on casing and plugging activities. In Oklahoma, protecting groundwater is the A #1 priority in the entire process. It doesn't cost that much to do it right, and if you read the link to that testimony, they insanely exaggerate problems with modern cement and casing jobs. That is just a fact. A fact, a fact, a fact. No company wants a casing leak or bad cement job. Say what you want about Halliburton, but they are the gold standard for well completions. I have rarely been in wells that used Halliburton because they are super expensive and just not necessary in plain old low pressure oil and gas zones. So company B is usually sufficient for most cementing and frac operations. Not so with the shale fracs. They are super technical, and just finding the appropriate frac recipe in each of these shale zones in various basins has improved to fit each rock.

So. You drill the well and case it for production. I know in the Marcellus that they are now using an extra 2000 foot casing string to cover the fresh water table.

OK. The permeability is so unbelievably low in those shales that you can drill the well, perforate and acidize the perfs (acidizing is where you pump 15% HCL into each set of perforations to dissolve the cement which often invades your formation for a few feet around the wellbore. I have been on tons of acid jobs. The injection pressure is way lower than a frac, and it flows back as CO2, water, and Calcium Chloride. Calcium Chloride is the salt that you see stores tossing on slippery ice at the front door. You can buy it by the ton if you want. So acid jobs are small and are only for cleaning up the perforations.

Back to perfs. After the well is drilled and cased, it is surrounded by an annulus of cement. You lower down a "gun" which is just a pipe with small shape charges to shoot holes in the casing over the specific zone you want to produce. Cementing is now a super refined science. It isn't just any old cement. It is complicated stuff and modern cement jobs are pretty darn good. For instance, I work a lot of limestone reef formations in Kansas. There are stacks of these porous zones on top of each other. You may have a 15 foot thick oil stratum with ten saltw#ter zones within 50 to a hundred feet above or below your target. So you perforate the oil zone and the cement keeps the adjacent saltw#ter zones from flowing into your wellbore. That ruins the well, basically turning it into a saltw#ter well which is plugged. So you only perforate your target. Cementing off the other porous saltw#ter bearing zones is a necessity. It works well, but there are occasionally poor cement jobs that do not isolate your zone and you lose the well and have to plug it. You know instantly when you have a bad cement job. BP should have known it on the Macondo well.

So you now have a drilled well with the target zone isolated and perforated. Shale reservoirs have such low permeability that you can open the sucker up to the surface and all you will get is a puff of gas at the most. The perm is so poor that gas can't migrate to the wellbore without inducing a fracture set.

Frac Process: This is a big industrial looking operation no matter how you look at it. The shale gas wells are frac'd along the 4500 foot to 9000 foot length of the horizontal section, so it is frac'd in stages along the wellbore. What this accomplishes is basically getting the equivalent of anywhere between 4 to 30 vertical wells along the length of the lateral. A vertical well might have a couple of hundred feet of the target shale in a vertical wellbore. If you drill horizontally you have thousands of feet of it in the horizontal leg of the well.

On the shale gas wells it takes a truly huge amount of fresh water. This part of the process is the A #1 problem in the shale fracs. It takes an incredible amount of freshwater (millions of gallons per well), and this puts all kinds of strains on local water supplies. The water had to be very clean from any mud (clay minerals) because those contaminates can clog the fractures. So you are having to truck millions of gallons of water around, and a water truck can only carry about 170 bbls of water per load. So it is an endless supply of trucks taking the water to the site, where it is stored in a pit lined with a thick poly liner similar to what is used in landfills. You have to use a high quality liner, or that fresh water will seep into the groundwater. At this point it is still fresh water stored on location. Nothing added. That happens during the frac job when it all gets blended and injected.

The frac: This involves an incredible amount of horsepower. Not so much to reach the pressure where the failure modulus of the rock to fracture it, but to inject at high rates. After the formation breaks you have to inject at a high rate to propagate the fractures. Since shales have such poor permeability, the aim is to create as many fractures as possible. It is so hard to do this that you can typically only get a fracture radius of a few hundred feet laterally from the wellbore. That is why you see 8 wells per square mile just to drain the accumulation.

Fracs are done in stages. It isn't just pumped in there willy nilly. The wells are perforated in small clusters a hundred to a few hundred feet along the lateral. So in essence, you frac one stage along the wellbore, isolate it with downhole packers, and then move back up and frac'ing a number of stages. The number of stages in some zones is as much as thirty these days, depending on the area and the rock mechanics. These shales are cored first, sent to a lab, and all of the rock physics is worked out to optimize the frac.

In essence, you are creating the equivalent of maybe thirty vertical wells along the length of the fracture for the cost of one very expensive horizontal.

When you frac a low permeability rock, the frac fluid is under high pressure. When you move the frac operation off of the pad, the well is under high pressure. You open up the well and that frac fluid comes screaming back at you. It is now contaminated with salt from the saltw#ter liberated along with the gas, so it needs to be handled with care. Chloride contamination of an aquifer is a disaster. Your water well suddenly becomes a saltw#ter well. You can't fix it, and you are looking at a big time landowner lawsuit.

This fluid comes back and is flowed back to the lined pit to be hauled off and disposed of in a deep porous injection zone. This is no big deal, disposing of the water. The Marcellus unfortunately has no sweet injection zone like we have in the mid continent...the Arbuckle/Ellenberger group.

You won't get all of the frac water back, but you get almost all of it back in a month or so. As the water flows back it begins to turn into a gas well which lifts the fluid and eventually the frac fluid is recovered and you have a gas well. Water in the wellbore creates high hydrostatic pressure and in essence kills the well until you can get that water back.

The high pressure part of the operation is the frac. Shale gas wells have notoriously low flowing pressure which is directly related to the low permeability of the shale itself. So after they go online, they are actually easy to control. The scary part is when you move in a small completion rig and open up the well to flow the load water back.

It is much scarier to drill a 22,000 foot gas well into an overpressured zone. That well might have 10,000 psia at the wellhead. Those are plain un-frac'd high pressure wells. There is infinitely more risk of having gas migrate up the annulus of the casing strings in these types of wells. 10,000 psi at the wellhead is a lot scarier than 1000 pounds of pressure at the wellhead. And shale gas wells have a very steep decline. They are pidly little gas wells after a year or two, sometimes as little as a few months. They will continue to produce for a long time at much lower rates, but the flowing pressure is low and the rates settle down. This is a hyperbolic decline curve, and I can look at a well decline and get an idea of permeability at a glance. I look at that many wells.

You also may need a million pounds of sand, which is also injected as a proppant to keep the fractures from closing after the frac job. Do you have any idea of how many truckloads it takes to put a million pounds of sand on a drilling location? That is why the roads are covered with trucks hauling material around. After the drilling is done in your area this dies back to almost nothing. So these people have to live with what is basically an industrial operation going on in their neighborhoods and they don't like it. That is totally valid and understandable.

The real problem with shale fracs is that this all involves an incredible amount of trucking and puts a strain on municipal water supplies in certain areas. It is no big deal in most places, but I see a lot of bitching in the Marcellus, and I assume it is factual. This is the root of the problem. Drilling and completing these wells is a big industrial process, and if for none other than aesthetic reasons, it is a beehive of industrial activity just hauling that stuff around. Hauling is where the surface contamination is also at most risk simply from spills.

The spent frac water that flows back is usually high in chlorides...plain old table salt, and chlorides in the groundwater will ruin an aquifer. That is why casing integrity is so important. And hey, if you get a casing leak in your production liner, you know it. You have a wellhead on there that connects to each casing string. If you blow your production liner you will see a huge spike in the annulus between that string and the shallower intermediate string. I mean, you know it instantly. A well with that problem is not that common, but if it happens you have to go fix the casing leak or plug the well, as it won't produce properly.

You know instantly of a casing rupture because the wellhead has pressure gauges on each casing string. The pressure gauge on the annulus of the producion string will spike, and the pressure on the production string will fall dramatically. Anyone with two feet can sneak onto a location and look at the pressure gauges. It is simple.

So you inject the frac water, mixing it with sand at the appropriate ratio, and also at that point mix it with the dreaded chemicals which are mainly drag reducers and clay stabilizers. The well will flow almost all of this fluid back. Remember that. Now you have to deal with it. Running it through city treatment plants or spraying it on roads for deicing is crazy, but has been done in the Marcellus. It isn't some cyanide laced deadly mix, but the load water picks up dissolved solids from the actual shale formation which famously includes barium and other things that you just don't want in your rivers and lakes. This is the big problem with the Marcellus: disposing of the frac water that flows back. It is no big deal in most basins because there are deep porous zones that will take zillions of bbls of fluid injection without pressuring up the disposal zone. The Marcellus, from my research, has a big problem becuase it lacks a deep disposal zone that is full of salwater and always will be full of saltw#ter.

It isn't like you explode the subsurface and rip holes in the surface. These zones are very deep, and although it sounds like a lot of fluid, it is nigh impossible for it to migrate through the rock itself to the surface. The obvious and well known permeability pathway to the surface is the wellbore itself. I know that Chesapeake is going overboard on the surface casing, running not only the surface conductor string and the surface string over any aquifer, but tossing in a 2000 foot cemented string for good measure. I heard that this is costing about 800 grand per well. They don't have to do it, and I'm not sure if other operators go the extra mile on this, but Chesapeake realizes that the frac issue is no longer about science. It is about public opinion. Chesapeake has its own rig fleet. Top of the line. I know people who work there, and they are the cream of the crop.

The only place that I know of with a problem of radioactive formation water is the Permian Basin in SW Texas. They had been using old production tubing for fences, playgrounds, you name it. Then they figured out that the scale accumulation in the tubing was loaded with NORM. Naturally occuring radioactive material. So that was a major freakout that was frantically cleaned up by removing all of that tubing. This was discovered in the seventies and is now well known.

Now. How do you actually know where these fractures go? This is something that nobody seems to know or admit. In order to study the fracs and maximize thier effectiveness, microseismic of frac jobs has been going of for over a decade. It is a lot like 3D seismic, where you get a great picture of subsurface features. It is super hot science.

You hire a seismic company for this. They lay out an array of geophones, which more or less listen. As the fractures propagate, they make noise, and the surface array can pick this up and model it. It shows you where the fractures are going. I have seen it up in the 3D room, and it is really cool. The objective is to maximize fractures in the shale and not to let fractures get out of zone. This can be a huge problem in parts of the Barnett in Texas because it lies on top of saltw#ter filled zones in some areas. If you get a fracture height that busts into the water zone, you lose your well. It will produce saltw#ter.

So you can see where the fractures are going. They do this to actually increase the frac effectiveness. On all of the ones I have seen, you may see one or two fractures that get fifty or a hundred feet out of zone..and these wells are 8000 to 10,000 feet deep. The problem is you find places along the wellbore with poor fracture density and hence it won't recover the oil or gas. I have seen it in shale gas wells and normal oil zones that are now being drilled with the big fracs.

I mean, I look at physics. And it isn't complicated.

The problem with the Marcellus is that it was never an oil or gas field and suddenly there is this massive rush of drilling and all of the damn trucking and industry that invades their countryside. I understand this and it is a super valid point. What they need to realize is that after the drilling in an area is done, you will end up with just wellheads producing gas. Not an oil field with wells every forty acres, which would be much worse, but bad enough for some people. Quiet farms are now overrun with massive trucking and huge rigs drilling. I saw the same thing in the Arkoma Basin. The drilling there has really slowed down because the sweet spot has been developed. Now you have a bunch of wellheads producing natural gas, and they behave like any normal gas well. Better in most cases because of the low flowing pressure of the wells.

I read that link above to the testimony that person gave and it is so skewed and crazy. He said that these wells are like thousands of dirty bombs just waiting to go off. Lying and exaggerating are not going to serve these people well.

I was sent a link to a 30 minute lecture from a guy from Princeton or some place. The guy had evidently worked at Schlumberger in the past and was passing himself off as an expert. He had his facts so wrong and it was so full of falsehoods. The guy didn't now jack. Now how are these people going to know the difference?

This is a lot like ANWR. What has happened is that the drilling boom there has caused a lot of concern because of the big industrial nature of these well completions. I can understand that. I don't worry about it in some places, because there isn't an inch of land that hasn't felt the plow or the logger. A corn field is not natural.

The coastal plain of ANWR is probably the most breathtaking wild country that I have ever seen, and most of you know that I have spent whole summers up there wandering around alone.

It is mainly the state of Alaska that spits out the propaganda over ANWR. Only 2000 acres will be disturbed and that crap. Well, the coastal plain will be politely industrialized. That is it. I am rabidly against drilling there for that reason. It is pretty easy to control land spills, so I have no doubt that it can be done fairly safely. I just don't want to see the wildest area in the U.S. to have a ton of production sites all over it. I have crossed that coastal plain at least 6 times on foot. I know what it is like. It is heaven.

Sure, when the wells are depleted it will be restored, but that tundra shows every scar on it for a thousand years. Yeah, it is mainly aesthetic, but the USGS put out a resource assesment inflating the probable reserves and the state of Alaska needs the money from the production, which is taxed in all states I know of except California. Alaska has no visible means of support and since 90% of the wankers never leave Anchorage, they don't give a damn about the place.

So I do understand the feelings over all of this industrialization of the countryside. It is limited to the well pads and pipeline right of ways, but it isn't pretty until the drilling part is over. So I understand it on a purely aesthetic basis. That should be good enough, and the anti frac people only do themselves a disservice when they make crap up.

The state of Alaska funds this outfit called Arctic Power, and they post pictures of all of the happy caribou around Prudhoe Bay. It is propaganda, and I hate it no matter which side is dishing it out. Arctic Power is f*#king evil. Go hit their website someday. It is the worst pro oil outfit that I have ever seen. I believe Exxon even stopped giving them money they are so bad.

I also know that the fresh water in upstate New York is unbelievably high quality. So the onus should be on the industry that they can do it right. They can do it right, but New York just has little experience in this area. So they are scared. I understand this, but the anti frac crowd should stop being stupid about the science and look at it from a factual point of view. The shale gas wells put a big strain on fresh water supplies, and moving all of that stuff around by truck is a nightmare.

Other than that, it is a gas field. The same thing goes on in droves all over the country.

As for Gasland, there was one example of pollution that was very real. The problem was that it was impossible for the average person to tell what was real and what was cherry picked information. I hold that film right up there with the BS coming from the other side in Arctic Power in Alaska.

Phew.

Below is a link to an article about the gas geysers by Okarche. I want to say that I am not stirring the pot or anything like that. I am fascinated by the oil industry and are genuinely curious about stuff like this. I remember watching the local news one night and they lead into a story about this and was going to come back to it after the commercial, but when they came back they didn't say anything about it. I thought it was odd.

I have a friend who drills water wells and he told me that one of the oil/gas companies was supplying people in the area with drinking water until they determined if the ground water was effected. I asked a friend of mine who is a petroleum engineer about it and he told me that (at that time) it wasn't yet determined what the cause was, but that it was looking like the problem was traced back to one well that had been drilled without following certain precautions that are required in this particular area from some reason. He said that his company won't even drill in this area because it is too risky for things like this to happen. I asked him about it recently and he said that it kind of died down and he really hadn't heard what the final conclusion was. I have always been curious what the outcome was but have never been able to find anything about it other than the initial news articles.

That is in the Cana Woodford play. Lots of activity there.

What most likely happened was that they had a problem with the overpressured Springer formation, which you have to drill through to get to the Woodford in this area. There is a ton of Springer production here.

No way is gas in the groundwater natural in that area.

That can happen when you have to drill through an overpressured zone. An overpressured zone is just a gas accumulation that has higher pressure than a normal pressure gradient of around .445 psi/ft. They are scary and you can blow out. This is the area where a blowout occurred this summer, also from the Springer. Rig burned and all that. You don't see too many blowouts these days like you see in the movie "Hellfighters." It does happen, though.

This happened twice back in the late nineties down in the deep Anadarko. It isn't the end of the world for the aquifer, like saltw#ter contamination is, but it isn't good in any way.

Hey, stir the pot on real world issues.

You are also correct that many companies avoid this area simply because of the greater cost associated with getting through the Springer Sandstones to the underlying Woodford Shale. There is an area over to the west in Ellis County where the Morrow formation is also overpressured.

El Guapo,

I read those news stories about the gas geysers near Okarche. I couldn't place it until I saw the date...2005. That is long before the horizontal play kicked off in that area.

That was a plain jane vertical well that was drilling. Same thing happened down north of Granite in the 90's on a Marathon well.

So that is one of the two famous cases in OK that I have been citing as examples of how gas usually gets into groundwater.

That Okarche well and the one down in Beckham County are famous, and the only big cases I know of in OK since I got out of school back in the eighties.

You ought to read the link posted above that shows the public comment this person gave. He called all of the gas wells dirty bombs just waiting to go off.

If you read nothing that I have said, read this: After the frac the well flows back all or nearly all of the frac water that is injected. It doesn't turn into a gas well until it spits all of that fluid back. Fluid in the well can kill a gas well. The hydrostatic pressure of the fluid column in the wellbore can exceed the formation pressure. So the well won't flow.

After you get the frac load back it is just a gas well. And the shale gas wells are low pressure gas wells to boot.

So Base104, the area around Twilight (my mom's farm, now mostly in the ownership of a good cousin, though we have retained a bit) outside of Wheeling WVA, is a 'safe bet'. I don't like the idea of us still relying on fossil fuels (though I have, somewhat benefitted financially from it), but I am still a realist (I think).

I just know if the sh*t hits the fan (in Ireland, EU and even US) that I still have a plot of (safe) land that Jennie and I can settle on. Just a shame the sea is so far away from WVA, after all, Jen grew up near the Irish Sea and myself the Bay Area, but we do have Wheeling Creek coursing through our land.

And yes, in these days and time if Chesapeake can return me some money, as long as environmental standards are kept, I'll gladly bank the check.

The problem is that the hysteria is so wrong.



When each of the gas company executives has a fracing well all around their homes and they don't truck in their drinking/bathing water…. Then I may consider the hysteria wrong… Until then (and I know it is highly unlikely that it will ever happen) I have to say no thanks, do proper studying, back to the drawing board, find a safe way to gather energy….

And now that I think about it….

Why don't they, the gas companies, go in search of their gas in major population centers?

Is it because there just happens to be no gas available in major population centers?
Is it because they (gas companies) know that its not safe, and they would never hear the end of it from the populations within those centers?

I think we all know the answers. Its too bad that even on a climbing site there are folks who would advocate such destruction of the environment...

That is pretty funny. Oklahoma City lies on top of the Oklahoma City oil and gas field, the biggest in the state. There is still drilling going on regularly inside the city limits.

A company that I do some work for has been in a number of wells in the NW part of the city....all frac'd. Big fracs.

That is also the rich part of town. The entire BOD of two of the biggest natural gas companies in the country live there. I can drive you by their houses. I have seen Aubrey McClendon's house, anyway. He is the CEO of Chesapeake. Devon Energy and SandRidge are also in OKC. That covers much of the biggest horizontal companies in the US.

There are wells drilled beneath Lake Hefner, the city water supply. The city likes the royalty checks. You can't use any motor boat on that lake. Sailing and kiting only.

I've been reading this thread with a somewhat detached curiosity until I got to this:

The only place that I know of with a problem of radioactive formation water is the Permian Basin in SW Texas. They had been using old production tubing for fences, playgrounds, you name it. Then they figured out that the scale accumulation in the tubing was loaded with NORM. Naturally occuring radioactive material. So that was a major freakout that was frantically cleaned up by removing all of that tubing. This was discovered in the seventies and is now well known.

My father was a production engineer for Shell Oil for over forty years and I was a child of the oil fields. As an aspiring hippie/environmentalist we had "lively" discussions over the record of the oil industry. I cut him some slack since it was clear to me that my middle-class upbringing was financed by big oil. In 1970, my dad was transferred to the Permian Basin, and I finished high school in Midland, TX.

In the summer of 1972, after my freshman year of college, my dad secured me a summer job at a plant in Midland called "Tube-Kote." The plant received daily truckloads of 40' joints of 2 1/2" oilfield tubing that had been pulled from wells after the tubing had become clogged with unmentionable gack and was now unusable. The joints of tubing were loaded on a rail car, run into a massive gas oven, baked at hellacious temps for several hours to burn out the gack. Then the insides of the tubes were sandblasted with long wands and all the charred detritus was blown out the ends using compressed air. The final step was to spray the inside of the tubes with a plastic/teflon coating and the re-furbed tubes were trucked back to the oilfields for a presumed new and longer life.

And now you're telling me all that gack that I burned, breathed, and shoveled all day every day for an entire summer was likely radioactive???

Something else to worry about, thanks.

Good evidence BASE104.
Good post.

So, you mean that hydro-frac is for the most part safe as can be. I'm assuming then that the cases of some (many?) populations drinking water being contaminated with unknown substances (mainly because the substances are proprietary secrets) is rare in your view, and possibly due to the shady practices of those companies that you don't work for....

Would you say that it is always best to do the frac anywhere and everywhere possible then?

Yes, it is complicated.
Yes, I have limited (i.e. not industry specific) information about the process of hydrolic fracturing and gas extraction.

Does this mean I cannot or should not raise questions about it?

Instead of heralding the successes of those companies that have extracted without incident of their secret poisons leaching into ground waters you be better served by raising the boats of those companies that leave destruction in their wakes. Sort of bringing up all companies to the level of those successful ones.

Also, minimizing the dangers never a good thing. Think how it would be if anyone who started climbing thought that they would live forever by doing so.

It is because it is inherantly dangerous that it should be taken seriously.... becuase it is.

Whoa, I hope I didn't add to the hysteria or throw fuel on the fire by asking my questions or posting those links. That wasn't my intent. I was curious about how that one particular event happened and turned out. Some of you guys turned my question into proof that wells are dangerous.

I live in the area that Base talked about with the wells in a metro area. They're pretty common. They're almost like (but not as numerous as) a telephone pole, a fire hydrant or an electrical transformer. They're just there and you drive by them and don't even notice them. I've seen wells right in the middle of housing developments. The wells were there first and the development was built around them.

I develop land, or used to before the economy went down the tubes. Most people don't think twice about living in proximity to a well, as long as it's not too close to their house (asthetics/view). We have bought land before that has a well on it and developed around it. In those cases really the only thing you're worried about is will the location of the well make it difficult to lay out streets/lots/etc or make it an unavoidable focal point as you drive in. We looked at one property that had three wells on it. Unfortunately the location of the wells made it almost impossible to lay out a neighborhood. If they had just drilled the wells all over at one side it would have worked out, of course when they drilled them many decades ago the land was in the middle of nowhere and the last thing on their mind was the future sale-ability of the land for a purpose other than agriculture. The owner is not going to be able to sell his land as long as the wells are there, but it's not because they're hazerdous. It's because they're all in the "wrong" spot.

I also built a house for a friend of mine who is a petroleum engineer. He is on a water well. An oil well went in about one mile from his house. He wasn't concerned about it. I guess that says something.

Studly - This is really only a small percentage of a very small percentage of a fraction of all the fracing operations going on all over the US….

This is certainly no real indication that hydro-fracing is not completely safe, or very minimally dangerous.

Just listen to Base104…


Base - Sorry if it seems that I am still not a believer in the line I'm being fed. I know that anyone making money in the business can hardly be an impartial judge to any of it… Just ask anyone on an oil-rig if drilling for oil is safe (not just for people, but for ecosystems as well).

Whoa. Stop the presses. You guys just missed it!

The link above to gas in groundwater is absolutely not to be dismissed. That new paper was published in the Proceedings of the National Academy of Sciences, the best journal in the U.S. Peer review in that journal is extremely thorough. It is the cream of scientific journals.

So I emailed a buddy of mine at Chesapeake and said that every Marcellus well should have pre-installed monitoring wells installed around it.

He just emailed me back, and Chesapeake is already doing it, and has been for some time. I need to ask whether they are sampling existing water wells or actually drilling a network of monitoring wells. Chesapeake is that serious about it, though. No modern large company wants a pollution problem. They just want to drill to the deep gas and produce it with no fuss. For a company like Chesapeake, even one incident isn't worth it.

Now it should be noted that in the paper they didn't find any evidence of actual frac fluid in the groundwater sampling. That doesn't surprise me one bit.

The PNAS paper couldn't tell where the gas was coming from, so this needs to be figured out. With a ton of monitoring wells it should be fairly easy.

No way to know without really getting after the study and trying to verify the results in the PNAS paper, though.

The PNAS also has some sweet global warming articles. Papers in super reputable peer reviewed journals can't be dismissed with a wave of the hand. Rush Limbaugh can say it all he wants, but he can't change physical evidence.

Believe it or not, there is great evidence of CO2 caused global warming in the fossil record. Unfortunately it gets shouted down by the deniers, who will never accept anything. Who know this? Mainly the petroleum geologists who work the subsurface and very old rocks. I will tell you that most petroleum geologists are conservative Limbaugh clones, though. I feel pretty lonely sometimes.

I accepted human induced climate change back in the nineties. The science was that good even back then.

Such is science when you have a bunch of non scientists interpreting the evidence however they like, though. Limbaugh or Exxon or Frack Action can get it all wrong, and nobody knows the difference.

So here is some good science that needs to be addressed.

I know the probable source, but I will wait on the science. I will say that this most likely has nothing to do with the frac. Those big freshwater fracs are the most benign fracs of them all. You ought to see a big crosslinked gelled saltw#ter or an acid frac or a CO2 or Nitrogen foam frac.

Yeah, disposal wells have been associated with earthquakes for decades. It is really rare, but it isn't difficult to correlate to the disposal well. The earthquakes are very shallow, up in the sedimentary rocks.

The Ohio case, just from the basic numbers that I read, make me 90% certain that it was caused by the disposal well.

There are zillions of disposal wells. Almost all oil wells also produce saltw#ter. Some wells make thousands of barrels per day of saltw#ter.

They either have a disposal well on the location or truck it to a commercial disposal well. Those wells are tightly regulated and have to go through annual casing integrity tests. That is called an MIT, or mechanical integrity test.

The earquake/disposal well link really came about from a couple of hazardous waste disposal wells at Rocky Flats in Denver, where they work with nukes and stuff. There were earthquakes associated clearly with the disposal wells and they were plugged. Earthquakes stopped. There used to be a few hazardous waste disposal wells for industry, not oil and gas related. I am pretty sure that they have all been shut down now. That was an old and bad idea.

The Ohio well will be shut in and plugged, trust me. It was shut in right after the earthquake. What happens is that if you inject with enough pressure you will pressure up your disposal zone. There are old faults all over the place in the interior US. If you increase the pore pressure it can lubricate the old fault plane and cause it to slip. That said, I know of many, many disposal wells right next to faults and they have no problem.

There is also a big correlation with geothermal wells and earthquakes as well. It is really common on some hydrothermal injection wells, which is clean energy.

The difference between a frac job and an injection well is this: The biggest frac jobs may inject 80,000 barrels of water, and the well immediately flows most of that right back in the first month. The injection wells may inject more than 10,000 barrels per day. And they do it for decades. A barrel is 42 gallons.

We have a perfect disposal zone in the mid continent: The Arbuckle/Ellenburger formation. It is super porous and permable, and usually at least a thousand feet thick. You can pump water into that sucker until the end of time without pressuring it up. Unfortunately, the Marcellus area is not blessed with such a good disposal zone. So what to do with all of that frac water that flows back? That is the real problem in the Marcellus.

There has to be at least 100,000 saltw#ter disposal wells in the country. The earthquake cases are super rare. The solution is to stop the injection in that particular well.

A basic principle of science is this: correlation does not equal causation. If you go off all half cocked on causation you run a huge risk of not determing the true cause. That goes for all sciences. There is experience, although uncommon, of injection wells causing earthquakes. The location of the disposal well to the Ohio earthquake and the shallow depth that it occurred makes it likely that it was caused by the disposal well. I don't know for certain, but I am sure that they have it nailed after a week of study. It isn't THAT complicated.

Yeah, as for what people call "Peak Oil," most geologists, and even bean counters, in the industry now think that the world has already passed its production peak.

That is not the really scary number. The scary number is when demand exceeds supply.

We are so insanely addicted to oil that it is like air. If you have a room full of people and the room is running out of air, people will pay anything for one of those last breaths. Oil prices are going to do the same thing. Rise to insane levels. The only reason that gas is expensive is because of demand.

We will see it in our lifetimes.

The way the US can stop the bloodshed is simple: use less.

We used to use a little over 20 million barrels per day. During the Arab oil crisis in the seventies, Carter put in all kinds of conservation laws. Does anyone remember him giving talks to the nation in a sweater? Everyone got behind it and turned their thermostats down to 68 in the winter instead of 72. Tiny cars like the Civic ruled the market and Detroit gas guzzlers went out of style.

Result? Carter took us from 20+ million bbls/day down to 15+ million bbls/day. That has never been remotely reached before or since. Prices crashed in the early eighties and gas was cheap again. Everyone started driving gas hogs again. Even now everyone thinks that they need a Dodge Ram or SUV. Result? We now consume more than 20 million bbls/day all over again.

That is the secret energy policy of Dick Cheney: Cheap oil at any price.

We can cut our dependence on foreign oil by a massive amount just from changing our habits. The damn Republicans keep blocking lower CAFE standards, though. They are neanderthals when it comes to energy and climate change.

No lie. Carpool when you can. Buy a high mileage car. Don't fly too much because that is the most fuel intensive form of transportation of them all.

We should also be using natural gas as a transportation fuel. It is the least carbon emitting of any of the fossil fuels and it is abundant and cheap. It won't last forever, but it will bridge us towards truly clean energy. US oil production is declining rapidly and nothing will really change that. "Drill baby, drill" is the biggest load of bullsh#t.

The only fuel we have in abundance here is coal and natural gas. Coal is filthy, but it is by far the most efficient fuel for electricity generation. Odds are that your computer is burning coal at this very second.

They even build coal fired power plants in Texas and Oklahoma. That really makes the natural gas industry ill.

Everone is all hung up on fracs. The real pollution comes out of all of our tailpipes. I wish it was purple so people could see it.

That is not the really scary number. The scary number is when demand exceeds supply.

I know of no economist who disagrees with your first paragraph, BASE, but I'm not sure what your last sentence means.

By "demand" do you mean quantity demanded? If so, that (and the quantity supplied) depends on price. Thus an inequality of supply and demand implies an inappropriate price. If you mean a schedule of quantities demanded at various prices (or quantities supplied at various prices), then an inequality of supply and demand follows by definition -- you would not expect to find the same quantity supplied and demanded at any particular price. That would occur only at an equilibrium price.

What I find scary is governmental attempts to manipulate petroleum and fuel prices (usually to make them too low). Since most of the economic players are well aware of the oil extraction situation, and are similarly aware that dependence on petroleum-based fuels at current levels is unsustainable, current prices, supply contracts, and long/short positions already reflect anticipated future events.

Despite this, I still read on this forum and elsewhere analyses (not yours) that imply that the price will stay at the current level, then suddenly jump to infinity when we "discover" we're out of petroleum. In fact, the market's actors already know we're out of petroleum; they just don't know when. Long-term prices reflect the participants' best guesses as to when.

While I can justify CAFE standards, for example, by noting that markets discount future pain, I personally think the real advantage of things like CAFE comes elsewhere. Specifically, one of the disadvantages of driving most modern low-consumption vehicles is their relatively slight mass. In a collision with a vehicle of greater mass, the more fuel-efficient but lighter vehicle usually ends up with the worst of it. CAFE, for all its other faults (and there are many), is at least a way to deal with the external safety cost to other drivers of potentially colliding with a tank disguised as an SUV, say.

I realize this has little to do with the topic at hand, but I personally think the topic of "peak oil" has had way too much sway in certain non-economic circles, and led to some often absurd analyses.

"Coal is nasty stuff. You won't find a petroleum geologist on the planet who likes coal. It is the most carbon intensive fuel of all. Natural gas is the least. Still bad enough for the atmosphere though."

Natural gas is not as clean as we thought.
Due to leaks, a lot of methane enters the atmosphere.
Methane is 23 times higher at greenhouse effect than CO2.

No one knows the exact leakage rate, but some have estimated roughly 4-7%.
4.5 x 23 = 100% additional greenhouse effect, which is a doubling.
So natural gas may be not be a great improvement in terms of greenhouse effect, unless the leakage rate can be decreased to 2.5% or less.
Some efforts are being made to do that.
Natural gas is still cleaner than coal in many other ways.

Methane is indeed a powerful greenhouse gas. If you look into it the only thing good about that is that Methane breaks down within 15 years or so. The only real way to sequester CO2 is for little tiny foraminifera and other bugs with a carbonate shell to die and rain down to the ocean floor.

OK. Peak Oil. This is much simpler than it sounds. The peak refers to the maximum production capacity.

For instance, oil was discovered in the US around the turn of the century (for practical reasons, that date is good). There was a huge amount of drilling, and with new discoveries the production capacity of the US grew. It far exceeded demand at several points and was actually cheaper than a barrel of water.

Anyway, the production capacity grew and grew and grew with more discoveries. Back in the early seventies, the production capacity in the US peaked at X number of bbls per day. It has been falling ever since.

Production capacity is one thing. So many bbls per day.

Demand is a totally different number. X number of bbls per day of consumption.

It is very easy to look back and actually see the peak in production capacity in the US, and the US has already produced more oil than any country other than the total reserves of Saudi Arabia. 190 billion bbls or so.

Lets say that production capacity was 100 million bbls per day. Demand is 80 or 90 worldwide. I haven't looked it up in a while.

So production capacity peaks at 101 million bbls per day. There are new discoveries all of the time, but depletion of older fields is greater than new discoveries are taking place. So lets say that 101 million bbls per day is the number.

You can drill all you want and not increase production capacity. Most production comes from the super giant fields that were discovered pre-1950 or so.

Production capacity starts to fall from that 101 million bbls per day number. Production has peaked and will now fall until the end of time.

Demand is still 90 million bbls per day, so even though production has peaked, you still have 10 million bbls/day of excess capacity out there. Controlling the spigot on this 10 million bbl per day is entirely in the hands of the few countries with the excess oil: Saudi Arabia mainly.

Since production is now falling, supply will now start falling until it meets the demand number.

When the production capacity number hits the consumption number, you then have a problem. When demand starts to exceed supply, it will be bloodshed. Oil is like air for our species at this point in time.

See? They are actually unrelated numbers.

You can't control the world's physical supply of oil. You can control, to a large extent, the world's demand of oil. So if everyone on the planet pulls their heads out of their ass, you can take demand down to 60 or 70 million bbls/day.

So the production number is really only important when it closes in on the demand number. That is when you will see the price of oil go through the sky.

It will be a good thing in my mind. Humans are nuts. We keep on burning fossil fuels because of one thing: greed. It is cheaper than the alternatives. When prices go through the roof, that will be the only time that people act. There are no altruists out there to speak of. Humans will only reduce their consumption of oil because of price.

A sad thing to say, but it is clear as hell.

Look at what you are driving. Look at how much flying you are doing, as that is the least efficient. Start sharing rides.

I know that you can afford to drive a big pickup or SUV, but do you really NEED that vehicle? My plumber does, but I don't.

It is coming, my friends. Most geologists that I know believe that we have reached our production peak already. As it falls, it will meet the demand number. From there it will be bloodshed.

This country funds a massive military that has a couple of aims. The first is protection of the US from attack. The only real way that will happen is with nukes. So we have subs and silos and a retaliation force. Mexico or Canada isn't going to invade us, and if they did, it would require a much smaller military to handle it.

So we have some huge number of Nimitz class aircraft carriers, with at least one or two always hanging out in the Middle East. We are fighting two wars in the middle east.

Other than blowing the Taliban to bits, which was achieved in the first year of the war in Afghanistan, it is all about oil.

You may think that oil companies control this card game, but they don't. Who controls this game is the hungry gullet of consumption. I will defend that statement until the end of time.

A really great read on oil and its relationship with power can be found in the book "The Prize." I highly recommend it if you want to understand oil.

We agree on that, BASE. I'm just being difficult because of definitional issues in economics. What an economist calls "demand" means a schedule of quantities demanded compared to the price of the commodity. The amount of petroleum products we demand at any given price is the "quantity demanded."

Thus, the "hungry gullet of consumption" varies its hunger based on the price. When gasoline is relatively expensive, we buy more hybrids and fewer gas-guzzlers. While this price sensitivity takes time to affect the quantity demanded, so does adjustment of the size of inventories of petroleum products.

I think it's these timing issues that confuse the non-economists (specifically populist politicians and the press). They say, for instance, "the amount of gasoline available is relatively unchanged, but the price rose sharply, so it must be some nefarious price manipulation." No, it's not. It's the price adjusting to anticipated future market conditions.

As long as the price is allowed to do so, we can keep that "hungry gullet" under control. When the price gets manipulated downward, however, then watch out!

Ohio earthquake was not a natural event, expert says
CLEVELAND (Reuters) - A 4.0 magnitude earthquake in Ohio on New Year's Eve did not occur naturally and may have been caused by high-pressure liquid injection related to oil and gas exploration and production, an expert hired by the state of Ohio said on Tuesday.

Ohio's Department of Natural Resources on Sunday suspended operations at five deep well sites in Youngstown, Ohio, where the injection of water was taking place, while they evaluate seismological data from a rare quake in the area.

The wells are about 9,000 feet deep and are used to dispose of water from oil and gas wells. The process is related to fracking, the controversial injection of chemical-laced water and sand into rock to release oil and gas. Critics say that the high pressure injection of the liquid causes seismic activity.

Won-Young Kim, a research professor of Seismology Geology and Tectonophysics at the Lamont-Doherty Earth Observatory at Columbia University, told Reuters in an interview on Tuesday that circumstantial evidence suggests a link between the earthquake and the high-pressure well activity.

"We know the depth (of the quake on Saturday) is two miles and that is different from a natural earthquake," said Kim, who is advising the state of Ohio.

Data collected from four seismographs set up in November in the area confirm a connection between the quakes and water pressure at the well, Kim said.

"There is circumstantial evidence to connect the two -- in the past we didn't have earthquakes in the area and the proximity in the time and space of the earthquakes matches operations at the well," he said.

A spokesman for Ohio Republican Gov. John Kasich, a strong supporter of oil and gas exploration in the state, said Ohio could announce a preliminary decision whether to continue the suspension of the wells as early as Wednesday.

The state was already looking into the cause of earlier seismic activity from 10 previous earthquakes, beginning in March, 2011.

According to Kim, this is not the first time Ohio tremors have been linked to human activities. "We have several examples of earthquakes from deep well disposal in the past," Kim said.

A quake of 4.2 magnitude in Ashtabula, Ohio, on January 26, 2001, was believed to be due to deep-well injection, he said. And in 1987 there was an incident with a correlation to high pressure deep well injection, he said.

There are 177 so-called "class two" deep wells in Ohio, according to Tom Stewart, executive vice president of Ohio Oil and Gas Association. They all operate under federal guidelines spelled out by the Clean Water Act.

There is no evidence that the wells in Youngstown were operating at higher pressures than allowed, Stewart said.

"We haven't seen anything from anyone at (the state agency) that would lead us to believe that the well was not operating properly," he said.

Kim said that even though the wells have stopped pumping water into the rock, the area might not have experienced its last earthquake. "It could take a couple of years for the earthquakes to go away. The migration of the fluid injected into the rock takes a long time to leave," Kim said.

Ohio's Democratic Senator, Sherrod Brown, said the quick response by the state shows it is a serious issue.

"There are things we need to know about drilling and earthquakes," Brown told Reuters on Tuesday.

Brown said he supports new energy exploration that brings jobs to the state but has questions about how companies will handle fracking and wastewater disposal. "They have got to answer the question of what they are going to do with the waste just like nuclear power," Brown said.

So what do you think would be a good guess as to when demand will meet supply in a way that causes things to really get weird? How do you predict it playing out after that? Do you think it will be more of a decades long event where we start to switch over to other forms of fuel (natural gas, ethanol, electric) or do you think we will just go after all the oil we can any way we can even if it means going to war over it?

You suggest natural gas for road transportation. If we were properly motivated by oil shortages, how long do you think it would take to get a useful number of gas stations equipped to sell natural gas? How hard is it to handle compared to gasoline (transporting it to gas stations, storing it, putting it into automobiles)?

The process is related to fracking, the controversial injection of chemical-laced water and sand into rock to release oil and gas. Critics say that the high pressure injection of the liquid causes seismic activity.

From what I've gathered, using the term "fracking" is a misnomer in this Ohio earthquake case. It sounds like they were just injecting waste material into a disposal well, which is probably pretty routine (I imagine). Yes, you can create seismicity (earthquakes) through fracking, but injecting water/waste down a deep well through a pre-existing fault zone - which sounds like was the case in Ohio - can cause seismicity as well. So saying it was caused by "fracking" isn't quite accurate... Routine injection? Yes. Fracking? No.

Besides, it's only a magnitude 4.2 fer cryin out loud. I'm curious as to what the highest magnitude earthquake directly caused by fracking or injection is. In Basel Switzerland a few years ago, they canceled an Enhanced Geothermal Systems test because they were inducing microseismicity, and there were a handful of magnitude 4's and 3's, but that's about the worst I've ever heard of.

There is also a big correlation with geothermal wells and earthquakes as well. It is really common on some hydrothermal injection wells, which is clean energy.

True dat - we can track specific seismic events (based on location, depth, magniude, and time) that directly correlate with fluctuating injection rates in an adjacent injection well. This works as a fantastic tool for measuring response in the reservoir - it's real-time data! These events are mostly between 0.1 and 2.0 magnitude - nothing anyone would ever really feel.

Also: this thread is great! No back and forth bitching like other OT threads. Lots of info is provided on both sides, and a respectful discourse is upheld. Keep it goin!

The were injecting wastewater from fracking opperations, so while it wasn't a fracking opperation that caused the quake, it was related to fracking.

Base, have you any info on the Shell exploration in the Chuckchi? The one tidbit I'd heard is that they say their seismic work indicates the geology is some of the best they've seen since the 30's, which puts it on par with Saudi, i.e. a mega field. Of course until they drill and delineate nobody knows for sure what it'll prove out to be.

The real question is are people on a global scale wise enough and self controlled enough to move towards energy efficiency and alternative energies in a timely enough manner to account for declining oil production over the long term. I'm generally an optomist, but I see a bumpy road due to greed and selfishness.

See? Look at the post above....

OK. There are probably at least 100,000 saltw#ter disposal wells in the country. You can use them to dispose of spent frac water as well. This is by far the safest method and it has a history going back to the beginning of oil.

Most oil wells, and many gas wells, make saltw#ter. Most oil wells make so much oil, so much gas, and so much saltw#ter.

Some wells make thousands of barrels per day of saltw#ter. They are only economic if they make enough oil to cover the disposal expense.

If you have a really sweet disposal zone, like the Arbuckle/Ellenburger cambro-ordovician limestone, that is usually 1000 to 2000 feet thick and already full of saltw#ter, a disposal well can inject thousands of barrels of saltw#ter per day. There are also numerous oil fields that are on secondary recovery waterfloods. That is where you inject saltw#ter to sweep unrecovered oil into producing wellbores. That has been going on since the beginning of time.

The relatioship between earthquakes and disposal wells is well known. If you overpressure your disposal zone, which can happen if it doesn't have great permeability, then the increased pore pressure can lubricate an old fault. The interior US is totally riddled with old faults that are pretty much dead. So it can cause one to slip. They are small earthquakes, but it is easy to correlate them to a specific disposal well because of their shallow depth. You shut down the disposal well and the earthquakes go away. Most of them are sub mag 2.0, but occasionally you get a bigger one like the Ohio one the other evening.

A frac job may inject 3 million gallons of fluid or more. This sounds like a lot, but if you consider the actual volume of the reservoir you are frac'ing, it is quite small. That frac fluid also flows right back.

So a big frac is maybe 80,000 42 gallon bbls of fluid. The injection wells take over 10,000 bbls per day, and they do it for decades. So you actually lower pore pressure in frac'd wells as they produce and the reservoir pressure declines as the well produces gas (all wells decline, and shale gas wells decline like crazy in the first 12 months).

So disposal wells and frac jobs are not related. Two entirely different animals from a physics point of view.

The real famous case of injection wells causing earthquakes was at Rocky Flats (Rocky Mountain Arsenal) back in the sixties. They had hazardous waste injection wells that were causing small earthquakes. Injection was stopped and the earthquakes stopped.

The thing about this is that it is not predictable. There are hundreds of thousands of class 2 commercial disposal wells and on site saltw#ter disposal or secondary recovery injection wells. Many of them are in places where there is intense faulting. The age of the faults in most of the paleozoic hydrocarbon basins are Pennsylvanian or older. Pre dinosaur old.

These faults regularly have little micro earthquakes on them, but they are dead. If there is a little stress on them they can still move a little, though.

I have said this before, but it bears repeating. In Pennsylvania and New York, there is not a geologicaly good zone to dispose of saltw#ter. Sure there are porous zones at depth, but just the power needed to inject saltw#ter makes it nuts. Ohio does have a good injection zone, and they are actually shipping spent frac fluid down to Ohio to get rid of it.

This is the entire problem with the Marcellus. You frac the well, the well flows the frac water back, bringing with it high chlorides and exotic things like Barium, and there isn't really a safe way to handle it. Treating it in municipal treatment plants is nuts. To really clean that water up it would take some kind of wicked reverse osmosis factory. Like the ones that convert ocean water into fresh water.

In the mid-continent, the Arbuckle is the deepest rock in the sedimentary section. Right on top of granite basement. It is super thick, super porous, and super permeable. It is already loaded with saltw#ter brine. You can inject an incredible amount of saltw#ter without having to inject at high pressure. It is so vast that you can't fill it up.

The geology here is great. There is a class 2 disposal well every fifteen miles or so. Saltw#ter and frac fluid get trucked over there and they are safely disposed of. So we don't see the groundwater issues that they see in Pennsylvania.

In a nutshell, disposal wells are totally different. I know of only one instance where a frac caused an earthquake swarm. It was in southern Oklahoma a few years ago. The were all mag 2.0 or much lower, so they weren't felt. They were picked up by the seismograph network. They were super shallow and could be correlated to the frac.

I know a frac sounds huge, but it is small when compared to the available pore space in the target rock, and the well flows that frac water right back at you. Disposing of it properly is the problem in the Marcellus.

There are thousands of horizontal stage frac'd wells in Oklahoma and Texas, and they are being constantly drilled in many plays, not just shale gas. We don't have any problems. The geology here is just very fortunate.

And remember. The biggest fracs may inject 100,000 barrels. And you get most of that right back. A disposal well may inject over 20,000 bbls each DAY.

The class 2 wells are super regulated and monitored for casing integrity. All of the smaller disposal or waterflood injection wells are tested annually.

I wish that it were easy to correlate injection with earthquake risk, but I don't know how, other than studying increasing pore pressure in the injection zone. There is a blizzard of dispoal and injection wells, and the one that will cause an earthquake is like trying to find a black snowflake in a storm.

I wish I could bill this time out.

Also, the disposal zones are way deep.

It is true that Fracking CAN cause seismicity, but it is only triggering the strain, not the stress. In other words, the stress builds up in the absence of Fracking and can potentially cause a larger Earthquake in the future. Fracking is only "lubricating" the fault zone to the point where slip occurs.

It is conceivable that we could trigger a magnitude 8 by injecting into the San Andreas, but it would likely happen anyway. We are overdue.

OK. I finally found somebody who hit the damn nail on the head.

I should give Paul a Supertopo Nobel Prize.

Yeah, there are problems with dealing with all of that water in the Marcellus, and it looks like they are having a real problem with gas in the groundwater from the PNAS paper. That can be dealt with, but it may require some big changes.

Everyone is all just jumping on this like it is the end of the world. Like companies are injecting cyanide into the dirt.

So. Obama opened up the Chukchi and offshore Beaufort Seas to oil and gas leasing a few years ago. I can't believe nobody jumped on this.

Offshore Beaufort starts 3 miles offshore from the coastal plain of ANWR, and all points west. I have peed in it a number of times I count my oceans by urinating in them.

The Chukchi Sea is the sea north of the Bering Sea. North of the Seward Peninsula, north of the Bering Straits.

It is covered with ice 9 months or so out of the year, and ice can blow onshore at any time of the year. Nobody knows how to clean up a spill on ice. Hell, you need an icebreaker just to get equipment out there in the winter months.

It is probably the most environmentally sensitive and difficult are to drill on the planet. There have been a few true offshore wells drilled in the offshore Beaufort, but none were put into production. You have to find a large enough accumulation to justify putting in a drilling and producing platform.

The Chukchi lease sale brought in billions of dollars. So there must be some really big structures beneath it.

A land blowout, even one like Macondo, would have been put out in a week or less, and it would have trashed a small area. The Macondo well wouldn't have even blown out if it were onshore.

That area has already been shot with seismic, so they know the traps are there. It is now just a question of whether or not they contain oil, gas, or saltw#ter.

Everyone is knee jerking about frac jobs, which have been around forever and are well understood. The geology in the areas is well understood. Yes, you can have problems with anything, but drilling in the arctic ice is spooky. The Canadians have been doing it, but that is mainly gas in the McKenzie Delta. Not fullblown offshore drilling. Just drilling is one thing. Modern engineering is up to the job.

The real problem is with the twenty or thirty years when the wells are producing.

I know of noplace where they are drilling 30 miles offshore arctic, like the Chukchi will be.

The Chukchi is also extremely shallow, so there has always been a worry about dealing with seafloor pipelines. The arctic ice is realtively thin, but it is still god's own bulldozer and scours the ocean bottom like crazy.

Yes, the biggest earthquake problems with injection have been with geothermal. You inject water and it comes back up as steam.

Just on the map I have open right now there are at least 100 saltw#ter disposal wells (no fracs needed in this area). There are tons of old faults. No earthquakes. It is rare and has nothing to do with fracs. Entirely different physical setting.

While not Arctic, the Kashagon field in the North Caspian is quite similar to the Chucki in terms of being offshore, 70km from Atarau as I recall, but it's been over 12 years since I was there. They are also shallow, as I recall about 10m deep, amazing that far offshore. They do get a fair bit of ice buildup as well during the winter and see -30F. Now that field is scary, high pressure ~10,000 fps, high H2S content, it was estimated 30% of the gas was H2S and high CO2 content, so very corrosive. I haven't kept track of that development, the rig was just starting to spud the first exploratory well the last time I was there.

I agree, cleaning up a blowout or spill on the ice would be very difficult if not impossible, depending on how thick/stable the ice was during the blowout. If it happened during breakup, forget it. It's unfortunate that there aren't more mega fields in easily accessed and developed environments, but alas the easy oil has been produced decades ago. Unfortunately technology and regulations only advance after catastrophes, and sadly have to be re-learned. One would think that after Piper Alpha the industry would not take shortcuts offshore, but sadly the Deepwater Horizon proves that is not the case.

But geothermal is forever and always.

Rokjox - the idea of using fracking to open up an artificial geothermal reservoir is amazing. It's almost too good to be true. Folks have been trying to do it for years. It's also known as an "Enhanced Geothermal System." Only a handful of companies have been met with success however, under very particular and restrictive circumstances. Therefore not many are willing to invest in furthering its research and development.

With all the fear associated with fracking these days, I can't see a lot of people getting behind the idea...

B104, worth mentioning that the Norwegians and Russians recently agreed on rights in the Barents Sea, south of Svalbard and Franz Joseph Land, and at least some exploratory drilling has started in the Barents Sea, and perhaps the Kara Sea. Likewise, much of the Chukchi Sea is north of Siberia, and there are significant possibilities for oil and gas all along Siberia's north coast - about half the world's circumference. You wonder how well prepared they are for exploring for, let alone exploiting, oil and gas there.

That has already been covered in depth.

It was a disposal well, not a frac'd well. A big frac injects maybe 100,000 blls of fluid, and you get almost all of that right back as the gas comes in.

A disposal well can take 20,000 bbls of saltw#ter or spent frac fluid for decades.

The disposal wells can overpressure the strata that they are pumping into. Permanently. A frac'd well flows the frac fluid right back and then the gas flows and depletes the pressure in that strata. Disposal or injection wells have a long historic relationship to earthquakes, although there are hundreds of thousands of them that never cause a problem. There is only one good case I know of where a frac job caused earthquakes. Most were mag 1.0 or so. The largest was mag 2. Stopped the next day.

Oklahoma and Texas have tens of thousands of these horizontal mega frac'd wells with no problem. The big problem is getting rid of the spent frac fluid.

Base,

I've worked for a couple different EPC companies doing oil field design work on fire and gas and control systems for the past ~14 years, a combination of EOR projects and facility upgrades. Mostly in AK, but one stint in Kazakhstan on the drilling rig that did the exploratory wells on the Kashagon field helping them with permitting and shaking my head in disbelief at the politics involved in oil and gas companies, both the owners and the contractors.

Even though my expertise has nothing to do with formations, drilling or production, I find it's a good idea to learn as much as possible about the industry you work in. So between countless HAZID and PHAZER meetings, project documentation and internal company and client meetings, I've picked up quite a bit over the years. Amazing what you can pick up at a drill sight waiting for an operator just by looking at the map of the wells and what wells are producing, what are injecting, etc as well as production numbers.

I suppose I also have a vested interest in seeing Alaskan oil production steady over the long term as that's what provides my bread and butter, and what pays for our states government. I've seen several boom bust cycles and have been able to ride them out.

While I've never worked with Statoil, they have a steller reputation and it diddn't take much google fu to get some details.

“This is a public hearing!” Josh shouted as he was led away. “I’m being denied my First Amendment rights.”

Approximately 16 Capitol Hill police officers entered the hearing room and handcuffed Josh amid audible discussions of "disorderly conduct" charges, according to Democratic sources who spoke to the Huffington Post.

The filmmaker did not have "proper credentials", and an ABC News crew did not make the committee aware that they would be filming, according to the Capitol Hill newspaper The Hill.

After reading all this my fears are not of fracking specifically but globally what we are doing to our water supply. Land subsidence is one thing but have the true costs as far as contaminating water ever been properly assessed?

Comparing peak oil to peak water "While oil is non-renewable and limited, it is replaceable by other more costly alternatives; water is renewable and relatively unlimited, but there is no substitute and it is only useful in the precise places."

It is the entire global water-energy-food nexus being upset that worries me. Virtual water is nice but entirely dependent on energy. Fracking and the energy sector in general are a only a portion of the problem/solution.

Are we losing sight of the forest for the trees?

OK, this discussion is moving beyond theoretical to directly and immediately affecting my future. After scoping neighborhoods across the Los Angeles basin last weekend, our most likely spot to plan a life is Culver City. Our favorite house to purchase has one major drawback: walking distance to the Inglewood Oil Fields.

PXP is the company that owns or drills these fields, and apparently promised decades ago that they were shutting down, but as of this year they began exploratory hydrofracking.

I'm inclined to JUST SAY NO to buying there, because there is insufficient regulation and accidents seem probable in the next few decades. But then again, there are oil wells all over LA basin, and I've got no idea about the connectedness of groundwater in the region.

According to Culver City website, they do get municipal water from groundwater as well as piped in from other sources.

So all this thread that I read through has not mentioned the oil drilling history of the Los Angeles basin... any insights BASE104?

Would you buy a house and plan the next few decades of your life in a place that was within a few miles of known hydrofracking?

Would I die faster from smog against the foothills or groundwater contamination of hydrofracking? Is it practical to maintain a whole home water filter of activated carbon to block the hydrocarbons? That doesn't address any radioactive stuff....

Damn LA Basin. Damn economics. Damn limited locations of employment for basic science research, and ridiculously competitive job market. I'm freaking out a little now, like a frog thrown in hot water, but I'll probably get over it, like a frog in a slowly heating bucket of water.

Base, I appreciate reading all of the detail you have provided in your many posts, I have learned lots about oil and gas exploration... many thanks.

One question: You don't seem to draw a distinction between fossil carbon and biomass carbon. In terms of climate change, I think this distinction is critical.. using biomass carbon (wood, biofuels) for energy is only altering the kinetics of existing carbon cycling, while fossil carbon additions from hydrocarbons increase the total pool of atmospheric carbon. Big difference in climate change implications of those energy choices I think.

So I see a huge difference between using biomass carbon, which is going to end up as CO2 at some point anyways, for energy, versus fossil carbon, whose fate is almost certainly not to end up as CO2 unless we extract it and use it.

Thoughts?

I am still having a local battle with fracking issues that don't make the headlines, but are very real problems nonetheless.

Big mining trucks are still speeding wildly on our local rural roads.

It's a money-driven feeding frenzy.

Offhand I'd say fracking has a lot in common with nuclear industry from the standpoint of a lot of cutting corners on implementation / operation and a lack of financial accounting for the full lifecycle costs of appropriate pollution controls and waste disposal.

I think by the time this goldrush is brought under control a whole lot of damage is going to be done by slipshod / wildcat operators; either that or they'll institutionalize stupidity as they have with mountaintop removal in coal.

Bruce,i was waiting to hear from base myself. Fracking is hardly"methane neutral",wells have blow offs or pressure relief valves to let off pressure.This pressure ,released, is in the form of methane,amongst other chem vapors or solids.Methane does occur naturally,from swamps,caves,unnaturally from landfills and old wells.All this means,fracking just adds ,while we have no measure,a lot of methane to the atmosphere ,increasing greenhouse gases.

Next up, Fracknation. From this link: http://hotair.com/archives/2013/01/20/film-review-fracknation/

Film review: Fracknation
posted at 9:31 am on January 20, 2013 by Ed Morrissey

Full disclosure: I’m a friend of filmmakers Phelim McAleer and Ann McElhinney, producers of the new documentary Fracknation. I’ve been looking forward to this effort for some time, interviewing Phelim and Ann during the last couple of years as they prepared for and produced the film. Outside of friendship — and Ann and Phelim are a truly lovely and delightful couple — I wanted to get the other side of the fracking dispute represented in the cinematic arena, especially after Gasland and now Promised Land.

And make no mistake — this documentary succeeds in rebutting Josh Fox, the producer/director/writer of the documentary Gasland that touched off much of the anti-fracking activism. Phelim steps through a number of Fox’s claims inside and outside of the documentary, systematically undermining each of them. He includes a clip of his in-person challenge to Fox, which Fox tried to suppress, and another with a state official that cozied up to Fox — whose lawyer hilariously demands the film of the interview immediately afterward. (It’s amazing how little some lawyers know about the First Amendment.) Instead of speaking with Hollywood actors and the UAE (which provided some funding for Promised Land), Phelim speaks with the farmers in the supposedly-blighted areas of Pennsylvania, New York, and the Delaware Rivery Valley, as well as experts on fracking, water science, and environmental agencies.

The best part, however, comes near the end. One couple in the area have been particularly effective activists, giving interviews, appearing in Gasland, and protesting about their contaminated water supply. The EPA even came to Dimock based on their complaints to test the water supply specifically in their wells, which they claimed were contaminated by the fracking that had taken place in the region. When Phelim asks to interview them for Fracknation and to get the results of the test, they get belligerent enough to call a policeman (who turns out to be one of the most reasonable of all the people in the film) as well as threaten to pull a gun on Phelim. Only through a FOIA request does Phelim find out why — the EPA didn’t find anything wrong with the water, and they were smart enough to tape the meeting in which they told the couple the results.

Fracknation delivers a powerful debunking of the scare campaign against fracking and domestic natural-gas production. But don’t take my word for it — here’s Variety on the impact of Fracknation:

Those nursing the suspicion that Hollywood politics are awash in knee-jerk liberalism may well have their cynicism validated by “FrackNation,” a counterargument to the outcry over the natural-gas retrieval process known as “fracking” recently explored in Gus Van Sant’s feature “Promised Land.” But the more thoughtful and politics-oriented auds targeted by this well-reasoned film from helmers Phelim McAleer, Ann McElhinney and Magdalena Segieda will find plenty to chew over, including the possibility that perhaps all is not as simple as it seems in the world of nonrenewable energy.

Irish journalist McAleer narrates and serves as host to this briskly paced, low-budget and mischievous pic, presented as a rebuttal to Josh Fox’s Oscar-nominated “Gasland,” a docu that has been instrumental in building political resistance to a process seen by different factions as a godsend and an antidote to Big Oil. Fox is clearly depicted as the villain in “FrackNation,” from a “Gasland” post-screening Q&A where Fox refuses to answer McAleer’s simple questions, to a scene at Los Angeles’ Hammer Museum where Fox literally flees the camera.

McAleer makes a good case against Fox’s movie. From the farmers of the Delaware River Basin, for whom fracking hysteria has meant a loss of crucial income, to experts like James Delingpole, who somehow makes a fairly reasoned case that the anti-fracking people are the tools of Russian President Vladimir Putin (for whom the natural-gas market provides political leverage), most of the voices entertained here make a good deal of sense. But the filmmakers might have done well to address the animosity so many Americans feel toward the energy business in general.

And what did the New York Times think? You’d probably guess … and you’d be wrong:

Narrated by Mr. McAleer, whose previous documentaries have also argued against environmental concerns, “FrackNation” is no tossed-off, pro-business pamphlet. Methodically researched and assembled (and financed by thousands of small donations from an online campaign), the film picks at Mr. Fox’s assertions and omissions with dogged persistence. Much of what it reveals is provocative, like a confrontation with Mr. Fox about the presence of methane in the water supply decades before fracking began.

What’s clear is that Mr. McAleer knows his way around the Freedom of Information Act and has done his legwork. Besides talking to carefully selected scientists and water experts, he visits pro-fracking residents of Dimock Township, Pa., who are annoyed that their community is being characterized as a toxic wasteland. And he’s not above taking a sentimental detour to Poland to commiserate with a pensioner who can’t pay her energy bills, or reveling in the odd gotcha moment, like accusing a public official of “inappropriate ties” to Mr. Fox.

More than anything, “FrackNation” underscores the sheer complexity of a process that offers a financial lifeline to struggling farmers. Whether it also brings death to their water supply is something we won’t find out by listening to only half of the debate.

Fracknation will air on Tuesday evening on Mark Cuban’s AXs cable television channel at 9 pm ET. It’s a brilliant effort by Phelim and Ann, and it’s appropriate for all ages. The only violence in the film comes, unsurprisingly, from people who don’t want to have Phelim asking inconvenient questions.

I find it of interest that the filmaker specifically limited the size of his individual donations which were requested via Kickstarter.

Opps, sorry, "demonizing" individuals, don't see where I did that, posted a review of a movie...can you copy past the specific part where I demonized you? It's true that I must have just posted an unpolitically correct thing. Thanks for correcting me. As John notes above, additional facts are not needed or worthy of debate, Hollywood has already come out with their "truth".

The truth, Mr Beer, in the real world, is that every type of energy has environmental consequences that heads towards or are horrible. We pick and chose our poison, but until you stop YOUR energy consumption, you're just another hypocrite. I will say that Dr Steven Chu has been a welcome addition to the debate and implementations of policy, sad to see him leaving. May his replacement be as capable.

Of course, curiously, fracking wasn't shut down or even slowed down by him and his hires. Clearly he didn't consult you about it or perhaps he would have. But all he had was a damned fine brain, a Doctorate, extensive work in physics, he was the Director of the Department of Energy's Lawrence Berkeley National Lab, where he led the lab in pursuit of alternative and renewable energy technologies. He also taught at the University of California as a Professor of Physics and Professor of Molecular and Cell Biology. Previously, he held positions at Stanford University and AT&T Bell Laboratories.

His research in atomic physics, quantum electronics, polymer and biophysics includes tests of fundamental theories in physics, the development of methods to laser cool and trap atoms, atom interferometry, and the study of polymers and biological systems at the single molecule level. While at Stanford, he helped start Bio-X, a multi-disciplinary initiative that brings together the physical and biological sciences with engineering and medicine.

The dude is the holder of 10 patents, and has published ~250 scientific and technical papers. He remains active with his research group and has recently published work on general relativity, single molecule biology, biophysics and biomedicine, and on scientific challenges and opportunities in clean energy. Over 30 alumni of his research group have gone on to become distinguished professors and have been recognized by dozens of prizes and awards.

Dr. Chu is a member of numerous honorific societies including the National Academy of Sciences, the American Philosophical Society, the Royal Academy of Engineering, the Academia Sinica, the Korean Academy of Sciences and Technology, and is an honorary member of the Institute of Physics, the Chinese Academy of Sciences, and a Lifetime Member of the Optical Society of America. He received an A.B. degree in mathematics, a B.S. degree in physics from the University of Rochester, and a Ph.D. in physics from the University of California, Berkeley, as well as 23 honorary degrees. and in fact had recieved the NobelFRIKKANPrize for Physics work. BUT HE WAS TOO STUPID TO CONSULT YOU ABOUT HOW HORRIBLE FRACKING IS SO FRACKING WILL JUST CONTINUE UNABATED. Obviously, in re-reading your post, I can see that YOU and Debra Winger know more than him based on a Hollywood movie.

Stay warm. Clean gas. Or we can stay with "clean" coal like you are suggesting. The US currently gets 50% of it's energy from CLEAN Coal. Maybe you can look into coal as a fuel source and the issues associated with it. Whatevaaaahhh works.

Ahh. It is beyond discussion from my end. It isn't that technical if you have been around wells for ages, but it is impossible to keep up with the information, both real and exaggerated, if you are a normal person. Who are you gonna believe? An actor or some slick oil company commercial?

Frack jobs on these horizontals use so much water and sand that it is just a huge industrial 24 hour per day process for anywhere from a few days to weeks. It takes so many trucks that it tears up roads and pisses off the residents. If you look at a place like the Arkoma Basin, where most of the drilling is done, it has settled down.

As far as methane in groundwater, when I was at Chesapeake, they had been doing pre-drilling sampling of all water wells around their pads. If there weren't any wells, they drilled them. Water wells are really shallow and cheap. They also had a division in geosciences that did nothing but study the natural methane that exists in some places of the Appalachian Basin.

Like I have always said, the mess exists moving that stuff around the surface. In the past year everyone has started using a company who can recycle the flow back load water and remove the solids and use it over and over. This saves money because fresh water is expensive, and it also relieves the strain on local water supplies.

There are so many places in oil and gas exploration that are being ignored because of the frac hysteria. In that respect it makes me a little sad.

I'm fracking a well next week. It will be a much smaller one because we aren't in a shale. Conventional reservoirs use vastly smaller fracs. I can sample the flow back water in gallon jugs. Anyone can go out to a location and do that on the sly. It isn't like they have armed guards out there.

You will find a lot of those nasty chemicals in your gas tank. I've never heard of them being used in a freshwater frac.

Right now, with gas prices in the gutter, drilling has slowed to a crawl in the shale gas plays. Everyone is drilling for oil. The joke is if you hit a gas well you will be fired.

It is just so hard for people to understand simple concepts. I watched the Macondo blowout play out on the big news networks, all with their own experts from academia. None of them could get it right. I could sit down with two beers, a piece of paper and a pencil and show you how BP negligently tried to cut a tiny corner. Everyone I knew knew exactly how that well blew out within a week as the info came out. BP was never admired, and now they are pretty much despised.

The problem with the exploration end of things is that the only people who are knowledgable about the technology work in the industry. College professors are usually not up to snuff. They don't let you go on TV and explain how the Macondo blowout happened. They get some expert professor on there and they get it all wrong.

We are drilling almost nothing but horizontal stage fracked wells in Oklahoma and Texas right now. We have really good regulatory agencies with almost 100 years of experience. Simple rules that are easy and not expensive to follow.

I'll say it for the thousandth time. An American uses something like thirty times more resources than your typical third world citizen. So when you talk about our 0.9% population growth, the effect is much higher. We are a little country, 5% of the world's population, and use 25% of the world's oil.

The whole shitty mess is going to be a nightmare for our grandkids, and it won't be fracking. People need to stop screwing and stop driving big cars and stop buying one car per person and stop the crazy train we are on as a species.

I see it in a geologic time sense. This period will have a groovy fossil record, a reasonably large extinction event, a big climate event, and the rise of some other species to take over our mess.

I'll just say this: I work with smart people who care about the planet as much as anyone, and we all shake our heads that the public seized on frack jobs to blow a fuse on. Meanwhile the real problems get pushed aside. We just shake our heads.

New York is doing it right. Anyone with a brain knows the quality of that watershed.

Sorry. I just don't feel like talking science over and over and over. Just stop using the stuff.

You state the following: "I really feel with all of this that i have been cornered into defending my turf.Local government has been bought,farmers around here do not want fracking.They want windmills.Yet ,fracking, will sail right through,so you could see the dismay of mine and plenty of others here."

I agree that local sentiments matter. In my neck of the woods, those who burn wood to heat their homes are villains this time of year, because the pollution from the particulate matter constitutes a much greater health hazard than the pollution from electricity generation or methane combustion. Your locality is apparently different.

And windmills here are now getting a bad rap because the local environmental community says they cause widespread destruction of migratory birds. As BASE104 says (or would say), all energy remains imperfect.

Your statement about farmers selling out confuses me. If they don't want fracking, but they're selling out, what's going on? Are the energy companies taking their mineral rights by eminent domain, or do these involve private, voluntary transactions? I don't want to work, either, but I gladly trade my time for money. Does that mean I'm being treated unfairly?

Finally, you ask who I would believe. I believe people in the industry, such as BASE104, on technical issues, because they are the ones with first-hand knowledge of what actually goes on in the field. I am particularly skeptical of Hollywood, because it is in the business of creating fantasy, and of the conventional, unspecialized media, because they are ignorant and subject to group think. Also, the conventional media seems to be more and more enamored of "advocacy journalism," or, as we used to call it, propaganda. When advocacy groups on either side of the fracking issue provide arguments, I examine their data and explanations and make my own decisions. I don't choose what to believe before hearing the evidence.

John,firstly,burning firewood is one of the cleaner ways to heat.Yes ,the particulate goes in to the atmosphere,there it combines with a variety of compounds and settles out through gravity,in effect cleaning our atmos phere.The same thing is said of forrest fires.As a geology prof once said"a solution to pollution is dilution".Not only does firewood do that ,it is carbon neutral,burning methane is not.

Secondly,windfarms are big here,and only getting bigger,farmers make more on their leases and less physical land is used employing mills=more crop yield.There are less[other than those you mentioned]possibly bad repercussions to their crops/livestock.Most farms around here grow vegtables for Birds Eye,a leading food company,they do not want to risk losing those contracts if things were to turn south with fracking.I can understand why farmers downstate[delaware river valley] want fracking,because the DOA has been buying them out and relocating them for decades.The farming sucks because of poor water/soil conservation practices.

And finally,Josh Fox,a resident of ny,grew up in pa.[as did i]From what i know,he made a documentary,had trouble getting distribution,accepted money from an actress,amongst others[yes liberals],to get the thing distributed.It was not made by hollywood.You can read into that whatever you want.The premise of the film was to show exactly what Base has said,what a huge industrialization fracking is.
What kills me is that all they[gas industry] have debunked is that the guys tap water does not light up.They have not even tried to say anything about what the rest of the documentary states,i.e.condensate pollution,surface and wastewater disposal,land use,misuse,etc.

Now if this were in the name of energy independence,maybe i could get behind it.But in light of recent findings that the gas companies want less restrictions, so they can export gas to countries that will pay more than us,i and many round here are more than against it.Especially with the things that COULD happen to OUR environment.

There are always solutions. But you are not going to get them from the ones profiting and you wont get reasonable ones from the hysterics.

I have been cleaning up the worst stuff in the USA for over two decades now, dealing with the results that the profiteers left behind and trying to find reasonable solutions that the hysterical people end up disagreeing with.

In every single clean up I have been on it would have ALWAYS been cheaper to not pollute in the first place. Allowing Frackers to inject "proprietary" chemicals into the ground is stupid. It may not "fix" the overall problem that Base refers to, but I dont see anyone on this thread willing to say, "No, I am not climbing this weekend to save gas so I can save the environment". Thats because it is not a real solution in this day and age. Which is not to say that we do nothing. We absolutely need to try and conserve. But at the end of the day we have to fix the problems that we can fix and not throw our hands up.

There needs to be tighter controls on fracking in terms of pollution pprevention. Pay now, or pay a LOT more later.

right now, with gas prices in the gutter, drilling has slowed to a crawl in the shale gas plays. Everyone is drilling for oil. The joke is if you hit a gas well you will be fired.

There in lies the rub, the cheaper the fuel the less money we will spend to find better fuels. So in reality, if oil could go really high then we could move on.

This is why building pipelines from the oilsands is not a good idea in the name of moving onto a cleaner alternative.

It would involve fewer regulatory hurdles - after all, they'd simply double an existing pipeline on existing rights of way, and increase the amount of tanker traffic through an already heavily used and regulated waterway.

It still crosses two provinces which makes it a federal gig, so still quite a few hurdles, less than keystone but more than within a single province

I'll say it for the thousandth time. An American uses something like thirty times more resources than your typical third world citizen. So when you talk about our 0.9% population growth, the effect is much higher. We are a little country, 5% of the world's population, and use 25% of the world's oil.

And another reason why we dont need the rest of the world trying to catch up, bottom line as BASE said, stop using it....if they lose customers...

Essentially to point out that central North America is rapidly producing more oil and gas,

Which is why they want to sell to Asia, to get at the world price of oil, right now they have to sell it cheaper in the North American oil market, they are losing billions and billions

Funny that what within a decade we completely blew out the notion of peak oil, we are set for centuries...so we really do need to figure out a way to move on

All boils down to what the cheapest energy source is.

Regarding the LNG and methane, I think if you look at the pollutants from coal and oil and compare it to the ones from LNG you end up putting less into the atmosphere with LNG.

However making gas liquid requires quite a bit of power so you need or should include that in your final calculations. This is why these plants will grab all the IPP power and go green.

Thanks Wilbeer for the edumacation that woodstoves are teh cleanest stuff out there. As Reagan announced and clarified years earlier, "trees are the largest producer of methane in the world". So I suppose if we cut them all down and burn them the world will be a much better place.

As far as your comment:
"i have not seen fracknation,so i cannot comment on Dr Chu"
Fracknation is a movie which has not come out, whereas Dr Chu has been the Secretary of Energy for over 4 years. I have this program on my computer called Google, I use it research things. Click here to learn more. http://bit.ly/JGvtyo

Hope that helps, you can enter "Who is Dr Steven Chu" to get more info.

You might want to clue the EPA in on the point you make on how clean woodstoves are, those idiots have it totally wrong as their chart shows.


Next, increasing the price of oil has been a goal of this administration. Gasoline for autos has doubled in the first 4 years of the Obama administration. However, despite what is noted upthread - this natural gas being fracked isn't so much competing with oil as with coal. The major use is production of electricity. Coal is the leading way we get electrical power and the numbers are shocking and staggering. A quick search of "clean coal" as an energy source should dissuade you that burning coal is a good thing on any level.

So if you want to stop the increased production of natural gas via fracking, have at it. But realize that what you will be getting then in place of natural gas for electricity production, is so much worse. As far as exporting it via liquefaction, have at it I'd say. It will increase the price and help reduce consumption (although the elasticity models of power don't show it to be significant, power is price elastic).

Unless we all go to those beautiful EPA certified clean burning woodstoves and can manage to make all those nasty "methane producing trees" to disappear off the planet.


BTW Wilbeer, the "solution to pollution" comment started out as twisted humor. That it has been advocated by academia now is a scary thought.

Wilbeer said:
"John,firstly,burning firewood is one of the cleaner ways to heat.Yes ,the particulate goes in to the atmosphere,there it combines with a variety of compounds and settles out through gravity,in effect cleaning our atmos phere.The same thing is said of forrest fires.As a geology prof once said"a solution to pollution is dilution".Not only does firewood do that ,it is carbon neutral,burning methane is not."

Oh, as far as your attempt to slam me for being a "republican", I'd rather be a republican than a dumbass any day. I may be a dumbass but sorry to inform you I am not a republican.

I do have a dog in the fight I'll share. I've invested a shitload of money into natural gas related companies and I suggest you look at doing the same. If you are interested in my thoughts on that, I'd be fine with sharing them but the short version is that because natural gas is so damned cheap right now, I've concentrated on companies that have large proven reserves. One hickup in the middle east and gas will go crazy due to speculation. Long term it's a no-brainer winner as well, as natural gas (and again, it's prime use will be electricity production) is one of the healthiest of our energy sources, there will be additional uses found and exploited as time goes on (car and truck conversion, new pipelines installed etc etc) and useage will increase thus driving up prices again. The Obama administration is trying to make coal go away and encourage that it go over to China. Talking long term on Natural Gas, it's a winner. Does fracking suck? Yes. Sorry, it causes environmental issues it really does. We know that. Is it a better choice than coal? Yes. Hands down no question. Dr Chu was a breath of fresh air after 8 years of Bush and an excellent choice by President Obama. With him controlling the game, I don't feel I need to micro manage the issue and that the peoples interest isn't being looked after, and you might consider that idea as well.

In either case, wish you well.

Couch,when we say fine particulate matter,Do you know what that is?Do you know what oil or ngas put in the air?Do you know what carbon neutrality means?Please educate me on that.
Particulates from wood burning, are far less toxic than carbon monoxides and unburned petrochemicals left behind from burning fossil fuels,while the fossil fuels have far less particulate in amounts,the matter they do leave behind is far more toxic.There are no perfect fuels and or energies ,but some are much" greener" than others[chemically speaking].
It is somewhat very similar of a discussion between diesel exhaust and gasoline exhaust,yeah the diesel has way more particulate[and looks dirty],but the gasoline exhaust has way more harmful chemicals.
I am sure you can pick this apart to.


And by the way in your previous "movie review" ,i would like to know how saying people against fracking are actually covertly with Putin .You are right ,thats not demonizing anybody.
Where did i say i dont know who Dr, Chu is?From your text,i took it as he had said something in the movie[which i have not seen,and all my previous comments were about the"review" of it]

DMT answered the question technically accurately, though as someone who spent nine years in the LA area, what constitutes "bad air" and what feels like "bad air" differ. Nonetheless, the San Joaquin Valley is one huge basin with prevailing winds that carry air -- and everything in it -- to the base of the Sierra and Tehachapi mountains. During the winter, a thermal inversion keeps that air stagnant, and particulate matter becomes a real health hazard.

Just look at what each fuel pumps into the atmosphere and then decide which is the best one, for now. So that we dont head past the amount of what we can put into the atmosphere in order to not surpass the 2c limit of warming.

Thats something like 565 giga tons more, which works out to about 16 years at the current rate with a 3% increase per year.

So if we can get into LNG we may be able to lengthen that time to transition to something else and start conserving

Not sure if this point was covered or not. It's well-known (that's punny!)that many oil and gas wells are not properly sealed when they are shut-in or abandoned. Operators are supposed to plug certain know zones where groundwater resides. So, if that is at 5,000 ft. they need to cement or shove bentonite down to those zones in the casing to prevent transmission of fluids in the event the casing erodes or is compromised.

Not sure of the frequency, but I know it happens more than we realize from well inspectors BLM and actual oil and gas personnel that have done this practice. A favorite practice to seal wells is just to plug the first several feet of the top of the well/casing and call it good and not even plug the zones where groundwater is found. Once the casing erodes and fills up to the groundwater zones, contamination is inevitable.

I wouldn't count on being able to use groundwater in areas of oil and gas development within 50-100yrs. after drilling began, give or take.

Base104: Casing leaks happen in certain areas

healyje: I'd say it's the combination of an inevitable percentage of casing leaks in combination with shoddy flowback disposal that are the problem with fracking. I'm guessing the former happens infrequently but can have fairly serious consequences, but having worked around the mid-south and having a pretty good feel for the kind of fly-by-night operators who are out there leaves me with far greater concerns with the latter.

So to the former, how pervasive are casings failures and how often are there serious environmental / health consequences as a result. To the latter, how many bad players are there and how big a problem is shoddy or criminal flowback disposal?

Maybe this is the better thread for asking this question...

Every casing leak that I have ever seen has happened years after any frack flowback. It takes that long for a corrosive zone to eat through that stout steel.

I'm sorry, but you guys have zero knowledge of how drilling and production works. If I could have a full day and a chalkboard, I could give you the basics, but a seminar on oil and gas production for non scientists costs several grand. Those courses are usually for non science types who work in or around the oil business. Management, land, banking, those sorts.

I'd try to explain more, but I'm tired of doing it over and over.

Every casing leak I have seen is from corrosive fluid on the backside of the production string. You still have two strings beyond that which cover groundwater. When you buy casing, it is drifted, pressure tested, and right before it goes in, the threads are electronically inspected. If a thread doesn't pass, it gets red spray paint and doesn't go in.

I get that probably most folks do things by the book and also that sh#t sometimes happens.

With regard to casings I'm simply trying to ascertain what the likely frequency of such casing failures as a percentage of the total number of wells (say per thousand wells) assuming the incidence is somewhere north of zero.

And I already know all about sketch crews in any number of fields - in this case I'm just trying to decipher - from someone who seems to me like they really know what they're talking about - what percentage of the fracking is done by crews likely to cut corners and cause problems - again, assuming the number is somewhere north of zero in the real world.

Having some idea of both, in combination with aquifer and water sourcing info in any given area, I should think would give at least a rough idea of the overall risk to drinking water supplies over time and how much state and federal oversight is required.

I also get that no one likes negative waves in the midst of a gold rush. I'm just trying to cut through all the hype on both sides to get a rough idea of the risks involved.

Close John,

The kelly is basically a square pipe that you screw into the top of the drill pipe at every connection. It goes through a square hole in the rotating floor and spins the drill string.

Now you remember, eh? The roughnecks sit in the doghouse getting warm, staring at that kelly going down. When you are drilling very deep you might have a ten minutes/foot rate of penetration. That's 300 minutes between connections. If they are lucky, morning tower gets to sleep all night....

Fracking waste deemed too radioactive for hazardous-waste dump

By John Upton


A truck carrying fracking waste was quarantined and then sent back to where it came from after its contents triggered a radiation alarm at a Pennsylvania hazardous-waste landfill. The truck’s load was nearly 10 times more radioactive than is permitted at the dump in South Huntingdon township.

The radiation came from radium 226, a naturally occurring material in the Marcellus Shale, which being fracked for natural gas in Pennsylvania and nearby states. “Radium is a well known contaminant in fracking operations,” writes Jeff McMahon at Forbes.


From the Pittsburgh Tribune-Review:

Township Supervisor Mel Cornell said the MAX Environmental Technologies truck was quarantined Friday after it set off a radiation alarm at MAX’s landfill near Yukon, a 159-acre site that accepts residual waste and hazardous waste.

[Pennsylvania Department of Environmental Protection] spokesman John Poister confirmed the drill cutting materials from Rice Energy’s Thunder II pad in Greene County had a radiation level of 96 microrem.

The landfill must reject any waste with a radiation level that reaches 10 microrem or higher.

“It’s low-level radiation, but we don’t want any radiation in South Huntingdon,” Cornell said.

Poister said DEP instructed MAX to return the materials to the well pad where it was extracted for subsequent disposal at an approved facility.

Pennsylvania is currently studying radiation issues associated with fracking of the shale and disposal of the industry’s waste.

"Of course, curiously, fracking wasn't shut down or even slowed down by him and his hires. Clearly he didn't consult (any of) you about it or perhaps he would have. But all he had was a damned fine brain, a Doctorate, extensive work in physics, he was the Director of the Department of Energy's Lawrence Berkeley National Lab, where he led the lab in pursuit of alternative and renewable energy technologies. He also taught at the University of California as a Professor of Physics and Professor of Molecular and Cell Biology. Previously, he held positions at Stanford University and AT&T Bell Laboratories.

His research in atomic physics, quantum electronics, polymer and biophysics includes tests of fundamental theories in physics, the development of methods to laser cool and trap atoms, atom interferometry, and the study of polymers and biological systems at the single molecule level. While at Stanford, he helped start Bio-X, a multi-disciplinary initiative that brings together the physical and biological sciences with engineering and medicine.

The dude is the holder of 10 patents, and has published ~250 scientific and technical papers. He remains active with his research group and has recently published work on general relativity, single molecule biology, biophysics and biomedicine, and on scientific challenges and opportunities in clean energy. Over 30 alumni of his research group have gone on to become distinguished professors and have been recognized by dozens of prizes and awards.

Dr. Chu is a member of numerous honorific societies including the National Academy of Sciences, the American Philosophical Society, the Royal Academy of Engineering, the Academia Sinica, the Korean Academy of Sciences and Technology, and is an honorary member of the Institute of Physics, the Chinese Academy of Sciences, and a Lifetime Member of the Optical Society of America. He received an A.B. degree in mathematics, a B.S. degree in physics from the University of Rochester, and a Ph.D. in physics from the University of California, Berkeley, as well as 23 honorary degrees. and in fact had recieved the NobelFRIKKANPrize for Physics work.

This is not frac water. This was drill cuttings. When you drill an 8 inch hole for 5000 horizontal feet, it is quite a bit. In most places it is just covered and buried in the pit, because in verticals this never happens.

I will have to check in on this, because there are thousands of Marcellus wells and this is the first one to have high radioactivity, which is common in certain areas. The Marcellus actually outcrops over a large area, so that rock is in the aquifer that people have been using for centuries.

The drilling in the Denver Julesberg Basin targets the Niobrara formation, which is a much younger and much different rock. The Niobrara has turned out to be kind of a bust. It is really only good in the Wattenburg field, which consists of thousands of wells around Denver up to just east of Boulder. Not IN Boulder.

I'll check on this. I don't work the Marcellus up in the NE, where this is, but I do work with other shales, and this doesn't happen.

I'm leary about this, because so many thousands of wells have drilled through the Marcellus, and there is a lot of hysteria over it. I'm sure right now that everyone is checking the drill cuttings. If it is at that level, it will have to be taken to a hazardous waste landfill. My wife regulates those. It is more expensive to use a hazardous landfill, but in the 9 million dollar cost of these wells, it is just a nuisance.

Remember. This isn't from water. This is from the actual rock cuttings that are circulated up and separated from the mud stream. I have sat at least a couple of hundred wells, and the geologist looks at samples gathered at every ten feet.

The only real NORM problem that has occurred, is in the Permian Basin. Almost every single oil well produces associated saltwater, and over the years you can get scale buildup inside the production tubing, which isn't casing. It turned out that this scale from one zone was highly radioactive. The old tubing, which has to be replaced every decade or two, had built up a very radioactive scale, but it took many years to build up.

So all of that tubing, which had been used for fences and even things like swing sets, had to be found and disposed of properly.

Frac fluid is only in the formation for a few weeks. Most of it comes flowing back in the first few days. I've never heard of radioactive frac fluid.

This is a huge concern in the exploration industry, because public perception, even if it is false, has an impact. Right now we are seeing the really big companies coming in and buying out the smaller guys. The big companies have the resources to handle almost anything. If the Macondo blowout had happened on land, it would have been controlled within a few days, and could have been cleaned up.

Over the past few years, the flowback fluid has been recycled and used over and over again instead of purchasing clean fresh water, which is a big expense. The service companies now have "green" frac fluids that don't contain any toxic materials, and in general have been dealing with the problems that are unique to the Marcellus, which lies in Pennsylvania and associated areas.

These big stage fracs have been under a lot of scrutiny. You or anybody can go out to the pit and take samples of the flow back fluid, and this has been done many times. This case has nothing to do with the fluid. It was the actual rock that comes up in the drilling. I've NEVER heard of this before, but the shales are more radioactive than other shales. One of our logging tools is a gamma ray scintillomiter, and is run on modern wells. We know how radioactive the rock is that we are drilling through, and in all of the mid continent and rocky mountain basins (which are not "in the mountains.")

Everyone here knows how green I am, and if this isn't a spiked load of cuttings, it will have to dealt with. It isn't radioactive waste type radioactivity. It is just above the line for type one landfills.

The drill cuttings, if this pans out, will now have to be examined.

This is in the Marcellus, which is upper Devonian. The zone in eastern Colorado is the Niobrara, which has been produced for decades in vertical wells. Underneath the Denver area, the geothermal gradient is higher because it is in line with the Colorado Mineral Belt. The Niobrara is failing in most places other than the Wattenburg Field, so the whole Niobrara is very patchy. It isn't thermally mature in most other areas. There is a small place in the Powder River that I know of, but it is pretty small. Shales are really high tech, and I'm learning about the geomechanics, chemistry, capillary pressure and lots of other stuff that.

Do you guys know the association with Young's modulus and Poisson's ratio? These shales are examined with electron microscopes, x-ray diffraction, and the mineralogy is well understood. Every shale is a little different, and there is a learning curve to make economic wells.

I'm bummed today because a buddy of mine and his son were killed in the El Reno tornado two days ago. This guy was huge in the meteorology community, Nobody can believe that he was killed chasing. He did a lot of important work with Texas Tech on windspeeds and damage, along with successfully planting instruments that were hit by tornadoes, something that only he could pull off after zillions of attempts. His son and partner died with them when a tornado veered its course and caught them in their car, sending it flying and killing all three.

You are totally biased being a worker in the industry. Not totally sure how much weight we're supposed to put in your "Its all safe" call.

One question: Can you say with certainty that every frac operation is run to your exacting standards and integrity?

If not, then you cannot say that everything is always safe with any sincerity.

Bruce - Right, I guess I too have allowed my anti-frac bias to get the better of me, in that I read Base to be pro-frac at all costs. Yes, he will look into something further, but in the meantime let the fracking continue regardless of the consequences to the people and the environment the people live in.

It's almost like reading the idea that spins the commercials that suggest that there are no problems in drilling for oil i the gulf and how much better the place is because of the drilling… I haven't been to the south, but from what I've heard there are more people down there on some kind of public assistance than anywhere else in the country.

If it (the frac) was really safe, there would be no need to report anything. We never hear stories on the people that continue to breath as this is what people do. Never hear the story about the numerous cars that start every day… That's just how things work. And if fracing were truly safe we would have never heard about it because life would have continued without a hitch. But as it stands there seems to be enough of the bad news so as to outweigh the good news, not to mention who false the claims of "making a community all better" economically.

I agree with Bruce. I've always appreciated Base for what he contributes.

We do get blinded when we stand for a cause and we have to be careful about that.

My teachers points out that in his tradition their approach is to look at all the positives and benefits and ways that other opinions might be right before taking it apart. I think often times the approach is to understand deeply your opinion on something (fracking, clear cutting, whatever) and use those strengths to tear down the opposition *before* understanding fully the oppositions strengths. The inherit problem there is if you are proven wrong you undermine not only the point you are trying to make but also your broader goals.

Base - do you have any information regarding the fracking that is looking to begin probably starting June 11th here in Boulder Country? (June 10th is when the moritorium is lifted).

Very sorry to hear about your friends, Base - I'm really enjoying lurking and reading this one - brings back a lot of memories of the oil and gas wells drilled into the Devonian shale on my parent's land when I was 4 years old in the West Virginia hills.

Read Sinclair's 'Oil' a few years back and was absolutely amazed at how little had changed in the process of drilling from 1920's to the 70's. looking back at the family pics from those days makes it look like they were using the same equipment!

I remember the strange grey fracking waste was pumped into a pit that was then covered over; nothing at all grew in those filled pits for years and years

Jesus, the stupid Rubes in the White house have screwed the pooch again! This time the idiots have selected ANOTHER (see Dr Chu note above) PRO FRACKING HACK, a guy who is a MIT physicist no less (Ernest Moniz) to be the next Secretary of Energy.

Are they all just that stupid? He wants MORE electricity, cheaper. Where are they getting all these idiots? They clearly are not familiar with this web site, or they would be against fracking. Sh#t, do they just give about anyone a Doctorate these days? Sorry boys, looks like the new sheriff in town wants you to PAY LESS for electricity, which in turn will add shitloads of new jobs throughout the country as the cost to Mfg decreases, and you'll breath cleaner air while all that crap occurs. No way around it, they seem intent on cleaning up the environment by MORE fracking, not less. Ya can't even turn around and vote in the republicans either.

“Mr. Moniz has been supportive of nuclear power, clean coal as well as renewable energy. He is perhaps best known for a study published by MIT on the future of natural gas, which was presented to the Senate Committee on Energy and Natural Resources in 2011.”

“It’s cheap, there’s lots of it and there’s lots of it in places with high demand, namely the U.S., China and India,” says co-author and M.I.T. physicist Ernest Moniz. “Sequestration,” he adds, “is a key enabling technology for coal use in a carbon-constrained world.”

“The world needs both more electricity and less pollution. The goals are not incompatible, but the solution will require better management of demand, smarter use of coal as well as renewable energy sources, and increased use of nuclear power.”

Clearly the academics don't know sh#t about shinola these days. Pfft, pro-fracking and he's a Doctorate from MIT.

There are a ton of little gas wells that have been drilled in and produce from the Marcellus. There is a town in Pennsylvania where back in the olden days, they drilled incredibly shallow wells to light the town. This is also where the water caught fire in the movie Gasland. He didn't show the water from the other 4000 people in the town who deal with the same thing and have since day one.

I'm not proanything that trashes aquifers or makes people sick.

This all started in the Marcellus Shale in the Northeast. There have been no problems of any significance in the thousands of horizontals in the Woodfod Shale in the Arkoma Basin, the Anadarko Basin, or the Sherman Marieta Basin.

All I'm saying is that there is a ton of misinformation out there. Casing leaks for example. We have been dealing with those for decades. In parts of Kansas, there is a sandstone called the Cedar Hills formation. It is full of saltwater, but it is corrosive for some reason, and if you don't run an uphole cement tool to cement across it, you will get a casing leak within a few years and lose your well.

I take offense to you calling me biased. For the past five years I have been working limestone and dolomite reservoirs. Not shales, but I go to the meetings and see a ton of data.

So the general public is scared of this. Although we know that most of this stuff is so stupid that a one year geologist knows it is bunk, that doesn't matter anymore. The big companies who do a lot of this are doing all sorts of stuff that isn't necessary just to prove that the wells are safe.

I spent a year at Chesapeake, who was drilling more shale gas wells than any other company, and they had an entire hydrology and groundwater division that studied the aquifers in the Marcellus. They did pre-drilling sampling of all nearby water wells, and drilled monitoring wells. They didn't have to do it, but they spent a ton of money on it. Nobody wants a problem.

If you are going to call me biased, well you are wrong. I get to see microseismic, which records each fracture and where it is in relation to the wellbore. I've never seen a fracture get more than 100 feet out of zone.

These shales aren't everywhere, and many shales aren't suitable. The productive shales produce from silica rich layers that have clay rich ductile layers between them. The frac science is designed to frac the silica rich zone, because you can't frac the ductile shales. They have to be brittle to take a frac. The economic trends in the shales are usually 10 or 20 miles wide and maybe several hundred miles long. A lot of it has to do with thermal maturity of the Type II kerogen. It has to have been heated to a certain point for these organic rich shales to source the gas in the whole basin.

Right now I am reading everything about shales, because I am probably going to work in the Bakken in North Dakota, where all of the farmers are millionaires.

The U.S. has produced more oil than the reserves of any other country on the planet besides Saudi Arabia. There are so many wells in the producing basins that a map of them looks like a bird shot pattern. The wells that cause problems are the ones up to about 1965. They didn't have to case off the groundwater, which has been mapped in every state. They also didn't plug them worth a damn. Today, plugging standards are far tougher, but the thing is, plugging it properly is not expensive at all.

All of these basins have gas production dating back to he twenties or thirties. The gas shales are deep. 8000 to 12000 feet. The thickest one I know of is 400 feet. It is overlain by a sedimentary sequence that is thousands of feet thick. The typical sedimentary sequence is 90% shale, but not the organic rich shale that is brittle enough to be fracked, and it doesn't carry organics to begin with.

I was on a rig once when the operator let the mudpit overflow. I was woken by a very irate inspector, and happily gave him the home phone number of the operator, leadint to a fine, although it wasn't a toxic release. I never worked for them again.

I'm desperate to get off of hydrocarbons. I believe in global warming, because these organic rich shales were deposited in anoxic conditions cause by ocean acidification, which was caused by CO2 forced hothouse conditions just like we are doing.

Natural gas is by far the lowest carbon fuel, but our country has a huge gullet for oil. We now import over half of what we use. The dream has always been to switch to natural gas instead of oil as a transportation fuel. Transportation fuel is by far the biggest use of oil.

We totally waste the stuff, and it is sickening. We have a nigh endless supply of natural gas. The problem is that alternatives are much more expensive. People look the other way and fill up their big trucks that they don't need, and drive them around every day with only one person in the truck.

I just understand fracks. We have been fracking wells for many decades, and haven't had any problems that I'm aware of. Jinghy doesn't understand the science of wellbore design, reservoir pressure (which is low in the shales), geochemistry, rock mechanics, anything. I deal with this every day of my life.

I'm not biased. I'm just saying something that he doesn't want to hear.

so Base, whats the point of this comment/question? does it have anything to do with the waste associated with fracking? no.

and its inconceivable to me that someone who deals with the subsurface does not know about radon. a noble gas that is commonly found in some sub surface areas which typically has a very short half-life of about 4 days.

Natural [edit]





Radon concentration next to a uranium mine.
Radon is produced by the radioactive decay of radium-226, which is found in uranium ores; phosphate rock; shales; igneous and metamorphic rocks such as granite, gneiss, and schist; and, to a lesser degree, in common rocks such as limestone.[53] Every square mile of surface soil, to a depth of 6 inches (2.6 km2 to a depth of 15 cm), contains approximately 1 gram of radium, which releases radon in small amounts to the atmosphere[2] On a global scale, it is estimated that 2,400 million curies (90 TBq) of radon are released from soil annually.[54]

Radon concentration varies widely from place to place. In the open air, it ranges from 1 to 100 Bq/m3, even less (0.1 Bq/m3) above the ocean. In caves or aerated mines, or ill-aerated houses, its concentration climbs to 20–2,000 Bq/m3.[55] Radon concentration can be much higher in mining contexts. Ventilation regulations instruct to maintain radon concentration in uranium mines under the "working level", with 95th percentile levels ranging up to nearly 3 WL (546 pCi 222Rn per liter of air; 20.2 kBq/m3, measured from 1976 to 1985).[2] The concentration in the air at the (unventilated) Gastein Healing Gallery averages 43 kBq/m3 (1.2 nCi/L) with maximal value of 160 kBq/m3 (4.3 nCi/L).[56]

Radon mostly appears with the decay chain of the radium and uranium series (222Rn), and marginally with the thorium series (220Rn). The element emanates naturally from the ground, and some building materials, all over the world, wherever traces of uranium or thorium can be found, and particularly in regions with soils containing granite or shale, which have a higher concentration of uranium. However, not all granitic regions are prone to high emissions of radon. Being a rare gas, it usually migrates freely through faults and fragmented soils, and may accumulate in caves or water. Owing to its very short half-life (four days for 222Rn), radon concentration decreases very quickly when the distance from the production area increases. Radon concentration varies greatly with season and atmospheric conditions. For instance, it has been shown to accumulate in the air if there is a meteorological inversion and little wind.[57]

High concentrations of radon can be found in some spring waters and hot springs.[58] The towns of Boulder, Montana; Misasa; Bad Kreuznach, Germany; and the country of Japan have radium-rich springs that emit radon. To be classified as a radon mineral water, radon concentration must be above a minimum of 2 nCi/L (74 kBq/m3).[59] The activity of radon mineral water reaches 2,000 kBq/m3 in Merano and 4,000 kBq/m3 in Lurisia (Italy).[56]

Natural radon concentrations in the Earth's atmosphere are so low that radon-rich water in contact with the atmosphere will continually lose radon by volatilization. Hence, ground water has a higher concentration of 222Rn than surface water, because radon is continuously produced by radioactive decay of 226Ra present in rocks. Likewise, the saturated zone of a soil frequently has a higher radon content than the unsaturated zone because of diffusional losses to the atmosphere.[60][61]

In 1971, Apollo 15 passed 110 km (68 mi) above the Aristarchus plateau on the Moon, and detected a significant rise in alpha particles thought to be caused by the decay of 222Rn. The presence of 222Rn has been inferred later from data obtained from the Lunar Prospector alpha particle spectrometer.[62]

Radon is found in some petroleum. Because radon has a similar pressure and temperature curve to propane, and oil refineries separate petrochemicals based on their boiling points, the piping carrying freshly separated propane in oil refineries can become radioactive because of decaying radon and its products.[63]

Residues from the petroleum and natural gas industry often contain radium and its daughters. The sulfate scale from an oil well can be radium rich, while the water, oil, and gas from a well often contains radon. Radon decays to form solid radioisotopes that form coatings on the inside of pipework.[63]

thats ok Base,keep telling folks its all good, trust those oil companies, get a job on an offshore rig run by BP. yep, its safe.

key parts of USGS findings:
The agencies said "183 earthquakes of magnitude 3.0 or greater occurred in Okla. from October 2013 through April 14, 2014. This compares with a long-term average from 1978 to 2008 of only two magnitude 3.0 or larger earthquakes per year. As a result of the increased number of small and moderate shocks, the likelihood of future, damaging earthquakes has increased for central and north-central Oklahoma."

"We hope that this new advisory of increased hazard will become a crucial consideration in earthquake preparedness for residents, schools and businesses in the central Oklahoma area," said Dr. Bill Leith, USGS Senior Science Advisor for Earthquakes and Geologic Hazards. "Building owners and government officials should have a special concern for older, unreinforced brick structures, which are vulnerable to serious damage during sufficient shaking."

The statement says "a likely contributing factor to the increase in earthquakes is wastewater disposal by injection into deep geologic formations."

"The water injection can increase underground pressures, lubricate faults and cause earthquakes – a process known as injection-induced seismicity," according to the statement.

"Much of this wastewater is a byproduct of oil and gas production and is routinely disposed of by injection into wells specifically designed and approved for this purpose. The recent earthquake rate changes are not due to typical, random fluctuations in natural seismicity rates," it said.

I'd like to hear what the industry has learned from this, how it self-regulates to put less waste-water back into the well or not when certain geologic circumstances are present, or to deeper depths, etc.

This has been know about since the induced quakes in the Denver area back in the mid 60's when they were pumping fluids down wells in the old Rock Mtn arsenal site. There were and are a lot of proponents of using this technology to create smaller earthquakes, so as to keep the pressure from building up for a larger quake. The obvious problem here is that a large potential release has already been building and the injection into the fault could trigger it. There are lots of people working on this problem, lots of differences of opinion, still a long way to go.

Interesting thread revival. Todays news it looks like you, the taxpayer, will soon be paying to try and make coal cleanER. As I satirically called it upthread, "clean coal". The name is total bullsh#t. The US is gifted with amazing reserves of coal, and in many years, when we do figure out how to burn it without the horrific environmental destruction it causes, we'll be in fat city. But if the coal companies want to pay to make their product clean, let them, or let West Virgina (Rockerfeller is one of the West Virgina senators) pay for it. Can we re-title the thread?
"Fracking, not even close to as insane as coal"

"Rockefeller introduces bills for clean coal incentives, research

By Timothy Cama - 05/06/14 08:33 AM EDT

Sen. Jay Rockefeller (D-W.Va.) has introduced a set of bills aimed at incentivizing carbon capture and sequestration (CCS) and funding federal research that could improve the process.

In addition to funding CCS research, Rockefeller’s legislation would expand tax credits for companies that use CCS, fund loan guarantees for constructing CCS facilities and fund retrofits of existing CCS facilities.

CCS is the process of capturing carbon dioxide emissions and moving them into storage, so that they do not enter the atmosphere. One of Rockefeller’s bills specifically targets the process of injecting carbon dioxide into oil wells to increase the wells’ yield, a practice known as enhanced oil recovery.

“The reality for West Virginia and the rest of the country is that we need coal; we can’t meet our energy needs without it,” Rockefeller said in a Monday statement. “It is simply unrealistic to think that we can stop burning coal and shift to cleaner sources of energy instantly.”

Rockefeller said he sees his legislation as a way to preserve coal as an important energy source while reduce its harm to the environment. West Virginia is a coal-heavy state, and the mining industry fears that government efforts to reduce carbon dioxide emissions could harm its business.

Eileen Claussen, president of the Center for Climate and Energy Solutions, praised Rockefeller’s proposals.

“Carbon capture and storage is a critical technology to cut carbon emissions while coal and natural gas remain part of our energy mix,” Claussen said in a statement. “Providing incentives to capture CO2 for use in enhanced oil recovery will help bring more commercial-scale projects online, which will help advance carbon capture technology and lower costs.”"

The 1 percenters want a new coal terminal to start exporting it much more significant quantities.

Yesterday morning the Santa Cruz County Board of Supervisors voted to ban fracking in the county.

Unknown to most, there are in fact a few small producing oil wells immediately adjacent to Big Basin and Castle Rock state parks. Just off Hwy 9 if you know the area. There's also a small production just above Hwy 84 west of La Honda.

Anyway, these oil formations are relatively close to the surface as evidenced by the supposed seeps (I've never seen them myself) in oil creek and coal creek. Since my water well is in an aquifer at 400 ft I have a personal concern.

Don't know if the aquifer is in Monterey Shale or above it. I know the Monterey Shale is beneath me somewhere.
We have no idea how deep the existing oil wells are.
I do know the strata slope downwards from my canyon towards Hwy 9 at a pretty steep angle. The strata could easily be 1000 feet below the surface at the wells.
Wouldn't know a capped aquifer if it bit me in the arse.
That's why I say I'm concerned about the fracking. Not freaking out. Now looks as if I don't personally have to worry.

I believe this is wrong. I mentioned above I've been told by reputable people there are some wells.
I was wondering myself what regulatory authority Santa Cruz County has.
While the state regulates underground wells, Tuesday's vote bans above-ground production support facilities. In doing so, the new law echoes a similar local effort from the 1980s to ban facilities for offshore oil drilling, an effective regulatory tool that became a model for coastal communities across California.

and it appears there is less oil in the Monterey Shale than earlier thought
Monterey Shale, a vast rock formation lying more than a mile underground that extends south through the San Joaquin Valley. While the U.S. Energy Information Agency estimated it to hold nearly 14 billion barrels of untapped oil, on Tuesday the agency downgraded its potential to 600 million barrels — possibly enough to deflate the debate over the issue.

I was also wondering about this
While fracked wells use water located far below drinking water aquifers, among Leopold's concerns is that wells could be breached and contaminate scarce local supplies.

Just a comment. Anybody with a water well as a drinking water (or any use for that matter) source can sample their water and have it tested to establish some sort of baseline for the well. Best to repeat the test a few times at different times of the year. Say, for instance before and after recharge events (ie substantial rainfall in many cases).

I asked "How do they do that? Are they using a different kind of gas? Maybe more abundant? Or is your utility just wanting to grease the slippery slope for their profits..?...

Then I thought are they doing what drug dealers figured out long ago.... first taste is practically free... because they know you'll be back for more... and by then it's too late.. the environmental damage is done

DMT,

Most of the shale activity is located in areas that weren't tectonically busted up as much as your cross section shows.

I would go into this again, but nobody understands the technical stuff. I've tried over and over. I suggest some reading. Go buy a basic Petroleum Geology book and glean from it what you can. You can learn a lot from a basic book.

Fracking is a red herring. There are tens of thousands of these wells now and there are very few accidents. In Oklahoma and Texas, most of the activity is in the horizontal plays right now. The rigs are all busy drilling horizontals.

Groundwater contamination is not a big problem. I haven't seen a single instance yet. Nothing like you will hear by watching fake Youtube videos or reading environmental blogs.

I do know of 3 cases of gas getting in the groundwater down in the deep Anardako Basin, but they were vertical wells that were super high pressure. The shale gas wells produce at a low flowing pressure.

This has me in a weird spot. I am a connoisseur of wilderness. I am adamantly opposed to drilling in the Arctic Refuge and have spoken out against it in the media quite a few times.

This is different. Most of it happens on land that is not in any way wild, in areas with a long history of oil and gas production. The problems that it brings are aesthetic in nature. It involves a lot of trucking of water and sand around until the area is developed. That is where the environmental risk lies.

I've seen the pro-development side lie through their teeth on things like ANWR. I've seen the environmental side lie through their teeth on fracking. It has worked. It isn't based on facts, but operators can't ignore public opinion. In Oklahoma, people are used to it. Still, there is a fairly vocal anti-fracking group. They do a really good job of screwing up reporting on it in an honest way.

OK. Everyone was all freaked out about the chemicals used in fracks. I'm pretty sure that all of this info has now been released.

It is pretty technical. Halliburton is the largest oilfield services company, and they have their own methods. There are other companies who do the fracks as well, though. Schlumberger, etc.

Yeah, Dick Cheney is probably the most evil American of my lifetime, but Halliburton is the best, as well as the most expensive.

It really is intellectual property, but I'm glad that they finally disclosed that.

This is just one of those things that has so much disinformation. I read false stuff regularly, even by supposed "science" writers.

edit: I just saw the above post about North Carolina. North Carolina isn't very prospective for oil and gas. I'm not aware of a single producing well. So the law is one of those stupid "masturbation" laws.

in california, the primary threat to groundwater statewide is simply agriculture as we currently practice it. we've already sterilized a huge chunk of the southern great valley and are hard at work on the rest.

the principal reason for opposing hydrofracking in california is simply this-- the state doesn't even regulate groundwater pumping. the state doesn't systematically monitor wells. we have a "voluntary" reporting system-- probably less than half of all wells even self-report.

hydrofracking isn't one of things i would prioritize for worry.

The Monterey Revolution ain't gonna happen, largely for the reasons outlined below in the abstract by Tom MacKinnon, former Chief Stratigrapher for Chevron. Several modern style hydrofracks have been attempted in the Monterey diatomite and chert in the last 10 years at South Belridge Field (see photo) with very limited success. Not sure how much more the land surface could be impacted at Belridge.


Geology of the Monterey Formation of California
With Comments on Recent Oilfield Developments

Dr. Thomas C. MacKinnon

Diatomaceous rocks and their diagenetic equivalents, chert, porcelanite and siliceous mudstone are abundant in Miocene deposits of the Pacific region. Of these, the Monterey Formation is the best known and most extensive. Its origin is tied to a fortuitous combination of tectonic, climatic and oceanographic events. In Oligocene-Early Miocene times, a change from subduction to a transform margin resulted in extension of the borderland and formation of new marine basins isolated from terrigenous input. In Miocene times, global cooling and changes in ocean circulation resulted in increased upwelling and productivity, and rapid accumulation of relatively undiluted biogenic sediment. Near the end of the Miocene, plate motion shifted from transtension to transpression, resulting in mountain building and a sudden influx of terrigenous material; this signaled the end of Monterey-style deposition in most areas of California. Rapid burial and basin-margin uplift continued through the Pliocene to the present, creating an ideal setting for oil field formation. As burial proceeded, soft diatomaceous rocks were converted to brittle chert, porcelanite, and siliceous mudstone. With further burial, organic-rich Monterey rocks generated hydrocarbons. Rocks overlying or adjacent to the Monterey included porous sandstones that made ideal reservoirs. Oil migration was aided by fractures in brittle Monterey rock types. Approximately 29 Billion barrels of oil have been produced in California, with roughly 90% probably sourced from the Monterey. Most of this oil has been produced from clastic rocks, leaving enormous amounts of oil still trapped in the matrix of low permeability Monterey rock types. In 2011 a report by INTEK, funded by the federal government, claimed that the Monterey Formation contained 15 billion barrels of recoverable oil, making it the largest resource base in the US. Using the INTEK numbers at face value, economists at USC predicted that California could experience an enormous economic boom. Both reports have been criticized as being wildly optimistic and not factually based, but not before they created a firestorm of public controversy resulting in new regulations on fracking. The main problem with the INTEK report was incorrectly assuming the Monterey would behave like the new tight oil and gas plays (i.e. Bakken, Marcellus) elsewhere in the U.S.; but the Monterey has little in common
with these plays. While it is clear that tremendous amounts of oil do remain within Monterey “shales” and diatomite, no easy way has been found to extract it. For decades operators have been using every available technique for enhancing production. This includes water flooding, steam flooding (lateral and huff-and- puff), CO2 flooding, and acidization, utilizing both vertical and horizontal injector and producing wells, some of which are fracked. There is no Monterey “Revolution”, however, operators will continue to seek better ways to extract the tremendous volume of oil remaining for many years to come.

___

RE the environmental impacts of hydrofracking in other States (e.g., Marcellus Shale in Pennsylvania & New York, Bakken Fm in N Dakota, etc), I'd say the jury is still out.

IMO, the greatest risks to the environment from hydrofracking are...

1) the existence of poorly completed wells that can serve as vertical conduits for drilling mud, frack fluid (flow back), produced fluids, methane, condensate, etc. and gas blow outs during drilling or production operations. These wells may or may not be known to the operators;

2) inadequate or poor cement jobs in the vertical portion of new hydrofrack wells that can serve as vertical conduits. Sometimes these poor cement jobs are identified with cement bond logs and sometimes not;

3) mishandling of drilling, frack and produced fluids during drilling, well installation and fracking (especially by the smaller operators). Discharge of these fluids, that can contain elevated levels of naturally-occurring radioactive material (NORM)*, metals, and hazardous chemicals, to natural surface water or discharge to unlined surface impoundments that infiltrate into shallow groundwater;

* http://ehp.niehs.nih.gov/122-a50/

and

4) methane leaks to the atmosphere during drilling or from production facilities. Also the increase in methane flaring.

IMO, as long as the oil industry can keep hydrofracking as the focus of public debate, rather than how our society can transition away from a hydrocarbon-based economy, then they are winning and our children & grandchildren are losing.

Horizontal drilling and hydraulic fracturing have enhanced
energy production but raised concerns over drinking-water
contamination and other potential health risks. Specifically, the
presence and environmental implications of elevated methane
and aliphatic hydrocarbons (ethane, propane, etc.) in drinkingwater
remain highly controversial and require a distinction
between naturally occurring and anthropogenic sources.
Previous efforts to resolve these questions have generally
focused on identification of the genetic fingerprint of natural
gas using the molecular (e.g., C2H6/CH4) and stable isotopic
(e.g., δ13C-CH4, δ2H-CH4, or Δ13C=(δ13C-CH4 - δ13C-C2H6))
compositions of hydrocarbon gases. In many cases, these
techniques can resolve thermogenic and biogenic contributions
of natural gas and further differentiate between multiple
thermogenic sources (e.g., Marcellus production gases vs.
intermediate Upper Devonian gas pockets). However, these
parameters are subject to alteration by microbial activity and
oxidation and may not always uniquely identify the source or
mechanism of fluid migration. Moreover, they do not
necessarily identify the transport mechanisms by which
material would migrate into shallow aquifers. In contrast to
hydrocarbon gases, noble gases provide a suite of elemental
and isotopic tracers that are unaffected by chemical reactions
or microbial activity. Here we develop an integrated noble gas
and hydrocarbon isotope analysis to evaluate if elevated levels
of natural gas in drinking-water aquifers near gas wells are
derived from natural or anthropogenic sources and to
determine the mechanism by which stray gas contamination
occurs.

SUBLETTE COUNTY, WY
In July 2008, a hydrologist discovered that a water well in rural Sublette County, Wyoming contained foul smelling, oily brown water.

Benzene.
Lab tests revealed the well water contained benzene, a chemical believed to cause aplastic anemia and leukemia, in a concentration 1,500 times the level safe for people.

Subsequent tests showed contamination in 88 of the 220 wells examined in Sublette County, and the plume of contaminants stretched more than 28 miles.

When researchers returned to take additional samples, they couldn't even open the water wells; monitors indicated the wells were so full of flammable gas they were likely to explode.

National Energy Technology Laboratory (NETL) study finds no evidence of natural gas migration along fractures or faults upward through geologic strata from hydrofracking in the Marcellus Shale. However, the study did conclude that monitoring indicated microseismicity 3,800 ft above the Marcellus Shale in overlying geologic strata. To date, tracer monitoring has not confirmed any migration of natural gas or fluids into the overlying strata.

http://www.netl.doe.gov/File%20Library/Research/onsite%20research/publications/NETL-TRS-3-2014_Greene-County-Site_20140915_1_1.pdf

The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) has released a technical report on the results of a limited field study that monitored a hydraulic fracturing operation in Greene County, PA for upward fracture growth out of the target zone and upward gas and fluid migration. Results indicate that under the conditions of this study, for this specific location, fracture growth ceased more than 5,000 feet below drinking water aquifers and there was no detectable upward migration of gas or fluids from the hydraulically-fractured Marcellus Shale.

Hydraulic fracturing is a method used to improve gas and oil production from low permeability formations (shale and tight sand reservoirs). During hydraulic fracturing, large volumes of sand and water, with small volumes of chemical additives, are injected into low-permeability subsur-face formations. The injection pressure of the fluid creates fractures that increase oil and gas flow, while the sand holds the fractures open.

The research study, led by NETL’s Office of Research and Development, used natural and man-made tracers to look for evidence that fluid and gas in this area from the hydraulically fractured Marcellus Shale had migrated at least 3,800 feet upward to a gas producing zone of Upper De-vonian/Lower Mississippian age shale, midway between the Marcellus Shale and the surface. Microseismic monitoring from geophone arrays placed in two vertical Marcellus Shale gas wells were used to determine the upper extent of induced fractures.

During hydraulic fracturing at the Greene County site, researchers detected microseismic signals using downhole geophones. All signals recorded were at least 2,000 feet beneath the Upper De-vonian/Lower Mississippian gas field, and more than 5,000 feet below drinking water aquifers. Gas samples from the Upper Devonian/Lower Mississippian gas field were collected 2 months prior to hydraulic fracturing, and up to 8 months afterwards, and no evidence of gas migration was detected. Monitoring of the Upper Devonian gas field up to 5 months following fracturing produced no evidence of fluid migration.

This research was funded through oil and gas royalties from drilling on Federal lands legislatively directed to the Department of Energy under provisions of the Energy Policy Act of 2005, Complementary Program. The work was conducted via collaboration between government, in-dustry, and academia, in order to provide an unbiased, science-based source of information with which future decisions about shale gas development may be guided.

This study finds evidence of stray natural gas in shallow aquifers from deeper sources and that the mechanism is likely poor cement job or casing failure in the vertical section of the well. Also, one example of a gas blow out.

OK. What do you guys want to know?

To be clear, I do own mineral and royalty interests in a few areas with shale gas horizontals on them. They are from wells earlier in my career. We were producing from shallower, conventional wells. All of a sudden my monthly check goes up, I go look at the area, and see that it has a new horizontal on it.

Other than that, all of my current work is conventional vertical drilling.

These are small interests. Farmers are getting rich off of the shale plays. Geologists get a small cut in some deals if they are lucky.

The real father of modern hydrofracking is George P Mitchell who developed techniques for extracting natural gas from the Barnett Shale by improving the proppant suspension properties of frack fluids and fracking horizontal wells in multiple stages.

Daniel Yergin, the oil-industry analyst and historian, says Mitchell’s fracking technique is so far “the most important, and the biggest, energy innovation of this century.” It is also the most environmentally controversial.

Regarding the earthquakes rattling the snot out of Oklahoma, there is a lot of baloney out there on the web and in popular media.

When you frack a well, you have a bunch or high powered pump trucks that can inject the water/sand mixture at high pressure. After you are finished injecting, you open the wellhead and flow back all of that frack water. You get most of it right back, and you only affect downhole pressures for a short period.

That is why fracks don't cause very many earthquakes. There was a recent paper where there was an earthquake swarm associated with fracking a horizontal in southern Oklahoma. The were all less than mag 2.0.

Out of the other thousands of horizontal fracked wells, I'm not aware of any other earthquakes. I keep track of what is going on at the Survey, too.

On the other hand, injection wells have long been associated with earthquakes. In the past few years a couple of areas in Oklahoma have gone insane, with daily earthquakes in the 3.5 or less range. Still, 3.5 is a big deal, and Oklahoma is now having a lot more earthquakes than California. Injection wells are active for decades, and over time they can raise the pore pressure in the injection zone. Increasing this pore pressure is the culprit. Fracks only affect a tiny area for a few days. Injection wells affect bottom hole pressure til the end of time.

Almost all oil wells also produce saltwater. The saltwater is separated at the tank battery, and the oil goes into the oil tanks, while the saltwater goes into its tank. When the saltwater tank fills up, which might take years on some wells and days on others, you call up a company which manages a commercial saltwater disposal well. They truck away your saltwater and dispose of it in a highly regulated commercial injection well.

Those wells are closely watched and regulated, and have to have a mechanical integrity test (MIT) annually. They check casing integrity by setting a plug just above the injection perforations and pressuring up the casing. If you have a leak, you will see a rise in the pressure on the backside of the main casing string, at the annulus gauge on the wellhead.

Oklahoma injection wells now require daily records of volumes injected, and pressure readings between all of the casing strings.

The first area to begin having earthquakes was in an area that had no fracking going on at all. It was in a region where the Hunton Dolomite was being produced. Those wells made thousands of barrels per day of saltwater along with oil. The saltwater would have cost way too much to dispose of commercially, so operators would drill a deep disposal well on about every 3 square mile block, which might tie in to dozens of wells.

This was nothing really new. There are thousands of saltwater injection wells in the state, and there had been no induced seismicity.

This are was different, though. It involved a LOT of saltwater, and the injection wells were regularly scattered throughout the play.

The zone that everyone typically uses for an injection formaton in Oklahoma, Kansas, and much of Texas is the Arbuckle Dolomite, a very thick sequence of highly porous and permeable rock that lies beneath the oil production zones. The Arbuckle was already full of saltwater, and it is deep enough to prevent cross flow to another wellbore nearby. Nobody drills to the Arbuckle in these areas other than disposal wells. It's always been full of saltwater and always will be full of saltwater. In the Hunton production area it is about 1000 feet beneath the oil/saltwater producing Hunton zone. So you are taking water out of one zone and then injecting it into a deeper zone where it is safely out of the way. Back in the 20's, they would let saltwater run down creeks, and the super high chlorides would kill everything. After many decades, those areas have recovered, but a saltwater spill is considered just as bad as a land oil spill if both are small. Oil will get eaten by bacteria long before the chlorides can be washed out of the soil.

This is an important point: Saltwater is BAD. Think of frack flowback water as saltwater. It is usually far saltier than the ocean and contains contaminant minerals, but isn't considered hazardous waste. That is why offshore production can simply dump their saltwater into the ocean. Those wells don't typically produce much water, and it gets instantly diluted. This has been looked at from every angle, and even frack flowback fluid is almost all water, now contaminated with saltwater from the formation that you fracked. You can do a lot to clean up water, but it is extremely difficult to remove chlorides. That is why Pennsylvania was stupid to try to run it through municipal treatment plants.

All of these zones are deep, too. Overlain by miles of shale, sandstones, and limestones. Every pore space is filled with either saltwater, oil, or gas, basically. You can drill through a hundred porous zones full of saltwater just to get to a ten foot thick sandstone oil accumulation.

The only reason that you can even frack some of these organic rich shales is because they have a very high silica content. Numbers like Young's modulus and Poisson's Ratio are very important when drilling horizontals in the shales. They typically have zones of more ductile clay, which you can't frack, and zones of brittle high silica shale, which you can.

A horizontal well must be steered in a small stratigraphic interval, sometimes less than 30 feet thick, for it to be successful. A one mile lateral might have 30 sets of perforations, each requiring its own stage of the frack job. If the wellbore gets out of zone and into a ductile clay zone, you can pump into at at 10,000psi for days and never be able to inject the fluid for a successful frack. Today's wells are really considered to be successful on how many stages accepted the full amount of proppant.

These shales are overlain by thousands of feet of normal ductile clay rich shale with no hydrocarbons. You can't frack that with atomic bombs, and it was tried by the DOE in the fifties in Colorado and New Mexico.

OK. Saltwater and frack flowback handling are the big problems with these fracks. They are no different from a smaller frack on a vertical well other than their massive amount of fluid and sand.

Pennsylvania doesn't have a good disposal zone like the Arbuckle. They are trying all kinds of ways to recycle the frack flow back. There are already recycling systems being built in the SCOOP Woodford shale oil play in SW Oklahoma. They take that flowback, clean out the solids, and use it over and over again, which is a great help. This technology is going to be the future of how to handle frack flowback water.

More on Earthquakes later. It is not a shale. It is a thick, naturally fractured limestone that is being drilled up all over northern Oklahoma. The Mississippian Lime reservoir is famous for producing tons of saltwater. Like in that older Hunton play just NE of OKC, where we had a 5.6 several years ago, you have to tie in these wells to centralized saltwater disposal wells.

You increase the pore pressure and it can lubricate a fault, even a fault that hasn't moved in 200 million years. This is what we are seeing in Oklahoma right now. It is a horizontal play, but it isn't a shale. Shales don' make that much saltwater after they have flowed back the frack load. The Mississippian can produce with a 5% oil cut. 95% of the production is saltwater. At these oil prices, it is economic to produce that small of an oil cut as long as the overall fluid rates are huge.

Almost none of this has been published, but it is what is happening.

I can go into it more if anyone likes.

If done the right way, it is. The downside is that the shale gas wells drain a very small area, so you have to drill a lot of wells from each pad.

Each one involves an unreal amount of trucking to bring in the water and sand. It tears up the roads, is a damn nuisance, and affects the landscape, which is almost all farms.

I remember when they drilled up the Woodford Shale in the Arkoma basin in SE Oklahoma. There were endless trucks for several years. Now it has been mostly developed and it has died down. The collapse in nat gas prices has also halted a lot of drilling.

I was amazed that people latched on to fracking and made it a "problem."

BASE104: although the Gasland films were full of inaccuracies and disinformation and I agree the mainstream media almost never reports any of this accurately, the environmental impacts of hydrofracking is NOT zero. In fact, you just enumerated some of the environmental issues above (i.e., increased traffic & congestion, air pollution, enormous amounts of fluids that need to be handled properly, etc.).

The myth propagated by the oil industry is that because there is no evidence that fractures induced in low permeability formations at depth have propagated upward and directly impacted shallow drinking water aquifers, that these operations are entirely environmentally safe.

Here's a list of impacts to be considered as part of an environmental assessment by the US Agency of International Development (USAID) for the development on shale gas in the Ukraine...

Water pollution from storing and transporting chemicals and fuels

Contaminated drinking water from escaped gas/chemicals

GHG emissions from extraction and production of gas

Leakage of VOCs from gas wells and compressor stations

Changes in sub-surface hydrology, including long-term damage to aquifers from fracturing chemicals

Safety and air pollution impacts from well fires and blowouts

Contamination of soils and water from drill cuttings and flowback fluids (heavy metals, naturally occurring radioactive materials, and other pollutants )

Local impacts and economic disruption from influx of construction personnel and support services

Air pollution due to truck traffic and mobile generators

Impacts from new road building

Impacts from new lands development

Wetland/habitat degradation

Hi Base104, can you talk about the composition of the fracking fluid and substances that are injected? Your summary seems qualitatively different from what I had read about in the past. A quick search turned up this:
http://www.earthworksaction.org/issues/detail/hydraulic_fracturing_101
http://nysaap.org/update-on-hydrofracking/


Carcinogenic hydrocarbons used as solvents, and radioactive tracers... with large volumes of fracking, even low percentages of these components adds up to a lot of volume of nasty stuff being hauled in, aside from chloride and "saltwater," and low concentrations of some of these things leaking into groundwater can be a long term nightmare.

Yeah, they now have green frack fluids. I dunno how often they are used.

In one of the shale plays in Oklahoma, Continental has built two big water recycling centers. That is the way of the future.

It is so fashionable in journalism to paint these slick water fracks as some toxic brew injected into the ground. People just don't understand how oil and gas is found. I'll post up a geophysical log of a well for you guys to look at.

When drilling a well, after you reach total depth you call the logging company. Schlumberger is the best, but I've been using Weatherford a lot.

You lower these "tools," which look like twenty foot long stainless steel rods about 3 inches in diameter down the hole. You then turn on the logs and pull them up at a pretty slow rate. It can take all day to log a well if you have multiple runs. The tools have many instruments in them that measure porosity, permeability, lithology, fluid content, etc.

You evaluate the logs and then decide if you are going to plug the well or set production casing and complete it. I can look at a log and tell you a LOT. Very high technology. That is how I work. I spend all day building cross sections and correlating strata across areas in the producing basins.

The way that I have made most of my money is by finding zones that companies drilled right through and ignored, or didn't notice because of the poor technology in the 40's and 50's. So I look at a shitload of logs.

Organic compounds in produced waters from shale gas wells

A detailed analysis is reported of the organic composition of produced water samples from typical shale gas wells in the Marcellus (PA), Eagle Ford (TX), and Barnett (NM) formations. The quality of shale gas produced (and frac flowback) waters is a current environmental concern and disposal problem for producers. Re-use of produced water for hydraulic fracturing is being encouraged; however, knowledge of the organic impurities is important in determining the method of treatment. The metal content was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Mineral elements are expected depending on the reservoir geology and salts used in hydraulic fracturing; however, significant levels of other transition metals and heavier main group elements are observed. The presence of scaling elements (Ca and Ba) is related to the pH of the water rather than total dissolved solids (TDS). Using gas chromatography mass spectrometry (GC/MS) analysis of the chloroform extracts of the produced water samples, a plethora of organic compounds were identified. In each water sample, the majority of organics are saturated (aliphatic), and only a small fraction comes under aromatic, resin, and asphaltene categories. Unlike coalbed methane produced water it appears that shale oil/gas produced water does not contain significant quantities of polyaromatic hydrocarbons reducing the potential health hazard. Marcellus and Barnett produced waters contain predominantly C6–C16 hydrocarbons, while the Eagle Ford produced water shows the highest concentration in the C17–C30 range. The structures of the saturated hydrocarbons identified generally follows the trend of linear > branched > cyclic. Heterocyclic compounds are identified with the largest fraction being fatty alcohols, esters, and ethers. However, the presence of various fatty acid phthalate esters in the Barnett and Marcellus produced waters can be related to their use in drilling fluids and breaker additives rather than their presence in connate fluids. Halogen containing compounds are found in each of the water samples, and although the fluorocarbon compounds identified are used as tracers, the presence of chlorocarbons and organobromides formed as a consequence of using chlorine containing oxidants (to remove bacteria from source water), suggests that industry should concentrate on non-chemical treatments of frac and produced waters.

Impacts of Shale Gas Wastewater Disposal on Water Quality in Western Pennsylvania

Nathaniel R. Warner *, Cidney A. Christie , Robert B. Jackson , and Avner Vengosh *
Division of Earth and Ocean Sciences, Nicholas School of the Environment, Duke University, Durham, North Carolina 27708, United States

The safe disposal of liquid wastes associated with oil and gas production in the United States is a major challenge given their large volumes and typically high levels of contaminants. In Pennsylvania, oil and gas wastewater is sometimes treated at brine treatment facilities and discharged to local streams. This study examined the water quality and isotopic compositions of discharged effluents, surface waters, and stream sediments associated with a treatment facility site in western Pennsylvania. The elevated levels of chloride and bromide, combined with the strontium, radium, oxygen, and hydrogen isotopic compositions of the effluents reflect the composition of Marcellus Shale produced waters. The discharge of the effluent from the treatment facility increased downstream concentrations of chloride and bromide above background levels. Barium and radium were substantially (>90%) reduced in the treated effluents compared to concentrations in Marcellus Shale produced waters. Nonetheless, 226Ra levels in stream sediments (544–8759 Bq/kg) at the point of discharge were ∼200 times greater than upstream and background sediments (22–44 Bq/kg) and above radioactive waste disposal threshold regulations, posing potential environmental risks of radium bioaccumulation in localized areas of shale gas wastewater disposal.

The rapid rise of shale gas development through horizontal drilling and high volume hydraulic fracturing has expanded the extraction of hydrocarbon resources in the U.S. The rise of shale gas development has triggered an intense public debate regarding the potential environmental and human health effects from hydraulic fracturing. This paper provides a critical review of the potential risks that shale gas operations pose to water resources, with an emphasis on case studies mostly from the U.S. Four potential risks for water resources are identified: (1) the contamination of shallow aquifers with fugitive hydrocarbon gases (i.e., stray gas contamination), which can also potentially lead to the salinization of shallow groundwater through leaking natural gas wells and subsurface flow; (2) the contamination of surface water and shallow groundwater from spills, leaks, and/or the disposal of inadequately treated shale gas wastewater; (3) the accumulation of toxic and radioactive elements in soil or stream sediments near disposal or spill sites; and (4) the overextraction of water resources for high-volume hydraulic fracturing that could induce water shortages or conflicts with other water users, particularly in water-scarce areas. Analysis of published data (through January 2014) reveals evidence for stray gas contamination, surface water impacts in areas of intensive shale gas development, and the accumulation of radium isotopes in some disposal and spill sites. The direct contamination of shallow groundwater from hydraulic fracturing fluids and deep formation waters by hydraulic fracturing itself, however, remains controversial.

When there is that much money to be made there are no environmental impacts.

So we don't need to talk about how much water it takes to frack and we don't need to talk about where the wastewater goes or what it is; and we don't need to worry about any of those things . Everything is OK don't worry so much.

When we are done and doing something else really stupid for money you can clean up the mess.

Although I'm pro fracking (see my posts upthread) The study sounds like another grouping of bullshit to me The Larry. The oil companies should just release the list of chemicals in the stuff. I can understand why they don't, because people would go nuts. These comments from the vid seem obliquely related and of interest:
"The study was partially funded by the oil companies" and the scientist proclaiming "if you drank the surfactants of fracking water it would make a good laxative"


He (the "scientist") say's that it's even got the same stuff that's in your toothpaste, so it's clearly even good for your teeth. We can all drink the laxative and relax now.


Not. High Traverse has it right about "transparency". But at the end of the day, the last 2 Secretary of Energy's have been super smart guys from academia, where they know there is no free lunch. If you stop all fracking, your environmental and economic costs will go through the roof. So yes, fracking sucks but it's much much better than the alternative. The alternative being the US being an net importer of oil products and thus politically beholden to Middle Eastern countries, and burning coal to make electricity instead of Natural gas thus polluting the sh#t out of our country.

Word for word from the video Larry, I think I have accurately quoted it. If you want to check the video against my words, the toothpaste comment is made .42 seconds into the video by the "reporter". They cut to the scientist and at @.46ish he says the "If you drank the surfactant....." stuff. As he's speaking, the title underneath which they have written and is continuously displayed says: "CU RESEARCHERS FIND WHAT'S IN FRACKING FLUID" and underneath in the same caption "Report: no more dangerous than detergent".

Note the subtle manipulation? It's fracking FLUIDS they say, not Fracking CHEMICALS. It's as safe as products you use every day when you wash your dishes. Meh, you can brush your teeth with the stuff. No worries if it contaminates your aquifer and wells. Your clothes will be cleaner and you'll actually have cleaner teeth I guess. Note that they avoided running the list of "FLUIDS" they by any reputable scientists who are Doctors or health researcher specialists? In fact, they don't list any of the "FLUIDS"...err, chemicals. So I call bullsh#t. They all already know what's in that stuff. High Traverse says we need transparency: I agree. Put it out there.

I just shake my head.

Flowback water is very temporary. The well spits it right back.

Produced formation water is different. These wells don't produce just oil and gas. They, like almost all oil and gas wells, also produce formation brine. It is separated at the surface and goes into separate tanks.

Two different things. Flowback water is the water that you injected during the frack. It is contaminated by formation water to some extent, but the pure stuff is the produced formation water, which can contain all kinds of stuff. The primary danger is from chloride contamination in the form of sodium chloride. Once you get chlorides in an aquifer, it is impossible to clean up. A surface spill will kill plants.

Although we eat plenty of sodium chloride, you can experiment with this. Really high formation chlorides fall in the range of 100,000 ppm (10% by weight) salt. Mix some water with 10% Morton's salt and pour it on a spot in your lawn. Yep. It will kill plants. Nature will very slowly clean it up, but not nearly as fast as in an oil spill.

Most chloride contamination cases come from waterflooding (secondary recovery) operations. A lot of times in waterfloods they inject at higher than normal reservoir pressure. This means that an overpressured zone can actually flow saltwater to the surface.

These days, to get a secondary recovery project permitted, you must make sure that there aren't any poorly plugged old wells in the area.

Does anyone here understand hydrostatic pressure? Does anyone understand flowing pressures and how it relates to permeability?

These are very basic ideas. The problem with this discussion is that nobody knows how oil and gas wells are drilled and produced. It is that simple. Nobody here understands how wells are cased, how modern cement works, and how easy it is to protect an aquifer from wellbore contamination.

The risk is when you start moving these materials around on the surface. Modern wells protect groundwater very well.

Is that what they say to the people who have gas in their drinking water?

Is the same government agency that oversaw the gulf oil spill well the same one that oversees these wells? At the rate these are being drilled how much regulatory oversight is happening? My guess is little to none.

PSP, you need to read sometimes. You can't get your head wrapped around this stuff at the Zendo.

You can look this up on your own. I don't have time to teach you about petroleum geology, and when I have tried it here, it is forgotten 20 posts later.

You have no clue about the geology. You have no clue about the regulations, which are stout.

No petroleum geology lessons today. I'm sorting and filing several inches of paperwork stratigraphy strewn around my office.

I will say that it is CHEAP to protect groundwater. The regulations are not to be trifled with, and basically every modern oil and gas well follows them to the letter. It is routine. The vast majority of groundwater pollution caused by the oil and gas industry is historic. I've never been involved in a well which caused problems, and to be honest, I only know of 2 cases of natural gas getting into groundwater in Oklahoma. They were vertical wells that had not been fracked.

Yes, accidents can happen, but they are pretty rare these days. As per the guy in the movie Gasland who lights his water on fire, it was not consistent with the natural occurring methane in the Wattenberg Field. It was biogenic in origin.

It created quite a fuss in Colorado, and it was investigated properly.

I don't even want to get into the shallow gas in the Appalachian Basin.

There is a reason why Cheney made sure the process was exempt from numerous regulatory review processes ; because it would cost money and slow things down and expose the potential hazards.

One of the problems I see is these things are going in close to communities where most oil and gas are not as close and not as many. So the business as usual is in your neighbors yard and business as usual for industrial drilling doesn't mix (from an environmental Health point of view ) with residential living.

John; Base said the regulations are stout but a quick review shows they are exempt from many of the basic regulations and review . So Base is not addressing that when he acts like the expert and doesn't expose the true regulatory environment. It appears dishonest or naive.

My guess is they needed to be exempt because they put such nasty stuff into the ground they would never be allowed to do what they do if they fell under the typical guidelines for protecting groundwater. How do you protect groundwater when you inject pollutants into the ground , it's risky and shouldn't be allowed IMO.

For those who might be concerned about groundwater impacts of fracking in California...

State Water Resources Control Board

Lawrence Livermore National Laboratory (LLNL) is hosting a public meeting regarding the development of model criteria for groundwater monitoring related to oil and gas well stimulation treatments, as specified in Senate Bill 4 (Pavley, Statutes of 2013). LLNL is the expert that the State Water Board is working with to develop the model criteria for groundwater monitoring.

The meeting will be held at the Cal/EPA Building in Sacramento on December 11, 2014, from 8am to 5 pm. The meeting agenda will be sent in a future email notification.

At this meeting, LLNL will gather information on stakeholders perspective and ideas regarding oil and gas related activities on groundwater quality and the development of the groundwater monitoring model criteria.

Information about State Water Board SB 4 related activities, including subscribing to our email distribution (listserv) for Oil and Gas Groundwater Monitoring, can be found at:

• What should the frequency and duration of the monitoring be?
• Should there be any limitations or exclusions to consider such as:
• Lack of protected water
• Depth to base of protected water
• Hydrocarbon zone presence or absence
• UIC exempted aquifers
• Existing groundwater quality issues not related to oil and gas activities
Regional Scale Monitoring:
• In what areas should regional groundwater monitoring be prioritized?
• What will be the criteria for the transition from operator-required monitoring to regional

Thanks for that tradster, missed it the first time. I guess we've been brushing our teeth with some nasty sh#t. :-) Also, thanks Base104 on the well casing comments, however, although it mitigates migration of fracking chemicals, that doesn't mean it eliminates the problem.

We have some high quality people involved who have examined these issues. It's not like the Bush administration at all which was full of industry hacks (not that it made them wrong, only biased). Read Secretary Munuz bonifides (or former Secretary of Energy Chu, a Phd nobel prize winner) and consider if his (or their) support of fracking is in error. These guys are all about green energy and reducing the environmental impacts. http://en.wikipedia.org/wiki/Ernest_Moniz Read it.

The question "Are you for or against fracking?" is too simple a question. IMO, a more relevant question is "What is the US's long-term energy policy?"

If the long term policy is to squeeze every last drop of hydrocarbons out of the subsurface, create oil industry-related jobs, and leave the environmental and climate impacts to a future generation to deal with, then, by all means, "Frack Baby Frack."

The question, often framed by the oil industry, "Is it possible for a fracture induced at 8,000 ft depth propagate upward and contaminate a water-supply aquifer at < 1,000 ft?" is also largely irrelevant. This is such a low probability event that, for all practical purposes, the answer is NO. Are there existing poorly constructed wells that might serve as conduits for upward migration of injected or produced fluids related to fracking operations? Yes, there could be.

IMO, modern fracking techniques can be done in an environmentally responsible way, assuming all the precautions are taken to manage and contain drilling, fracking and produced fluids. The volume of fluids being used in these operations is staggering, so managing these fluids is crucial. Are these fluids properly managed by all operators, in all states? Not so sure. In order to protect water resources in these areas, a comprehensive surface water and ground water management and monitoring program needs to be in place including an evaluation of pre-fracking conditions to establish a baseline for evaluation of future impacts. The demand on local water supplies, if needed, for fracking operations is also an important consideration.

To investigate the impacts of past operations, in an oil or natural gas field that has been in operation for decades, is a complex problem that requires sophisticated forensics techniques, like the ones I've posted up thread. These methods use isotopic and noble gas mass spectrometry that are capable of distinguishing biogenic from thermogenic methane and determining the nature and timing of methane releases. EPA's investigation of environmental impacts from fracking operations at Pavillion, Wyoming appears to be flawed in so many ways that it too is irrelevant.

Furthermore, there are other environmental issues than water resources, such as air quality and "quality of life" to local communities. The increased amount of traffic and the associated congestion and air quality impacts related to fracking operations is significant and must be considered in any comprehensive analysis. One of the air quality issues is methane leakage. As we all know, methane is a much more efficient heat trapping atmospheric gas than CO2, so there needs to be a zero methane leakage policy.

Alternatively, if the US's long term energy policy is to begin to wean our society off hydrocarbon-based energy resources, then here are some suggestions...

1) develop a more coherent alternative energy policy with real economic incentives and federal subsidies that significantly reduces coal use and fossil fuel burning for electricity production and increases wind, solar, and biofuels;

2) strongly encourage the use and development of effective public transportation systems;

3) use natural gas as a "bridge" fuel source for transportation while encouraging the use of electric cars;

4) create economic incentives for energy-efficient homes and office buildings; and

5) develop safer nuclear facilities for electricity generation.

There are no easy solutions to the predicament we are in right now.

Here's a timely question that has no easy answer..."Should Obama support the $5.3B Keystone Pipeline that will carry 800,000+ bbls of crude/day from Alberta to Nebraska?"

I think we should do it. And now a bunch of Senators suddenly agree with the House. Playing politics?

I was for it all along.

1) develop a more coherent alternative energy policy with real economic incentives and federal subsidies that significantly reduces coal use and fossil fuel burning for electricity production and increases wind, solar, and biofuels;

Solar maybe, wind and biofuels seem contrived to fit a narrative. In the near future it would be easily feasible to outfit stationary structures with solar energy to lessen drain on the grid. This is already being done.

2) strongly encourage the use and development of effective public transportation systems;

Sure, but this isn't Europe. There are large swaths of suburban America where this would take a lot of work. It's not convenient enough to get people out of their cars. And there's the cultural part of it where Americans largely like the independence of their own transport.

3) use natural gas as a "bridge" fuel source for transportation while encouraging the use of electric cars;

Electric cars. How do you "encourage" that? And they still plug into coal factories.

4) create economic incentives for energy-efficient homes and office buildings; and

Sure.

5) develop safer nuclear facilities for electricity generation.

Sure. They are getting better. SOme of the older sites need to be moth-balled.

not so sure wind power is a contrived energy source although I agree we're a very long way from any of these alternative energy sources having any real impacts on electricity production


how do you encourage electric car use? Federal subsidies and incentives to design a low cost electric car with the necessary infrastructure...perhaps piggy-back on the Tesla infrastructure that is being developed for the privileged class.

Agree and disagree. The private-sector (Toyota, Tesla) will make this stuff happen far more efficiently, it should be left to them.

Sure Tesla is expensive, it's a luxury vehicle in it's infancy. It will get the cheaper, the market will demand that they compete with the Prius.

The Feds can give incentives to companies that make these cars in the form of corporate tax breaks based on sales.

The big problem with Fed incentives are phony loopholes and lobbiests. I.E., Solyndra and that silly car made in Scandanavia that we funded. Fisker?

Bruce,

Yes, TT's post was pretty spot on, but there is so much bad information out there that I honestly don't blame people for being so scared. Just go to Youtube and type in Fracking. It is nothing but ghost stories, and it shocks me that this is now the popular perception of how it works, but here we are. And PP can f*#k off, because he is basically calling me a liar. My wife is the director of one of the entire divisions of the state DEQ, and we have had many discussions on how drilling and production takes place in this state. She has a 30 year career in the regulatory field, and I have a 30 year career in the E&P field. And I am not lying. I'm being as bluntly honest as I can be.

This sudden fear of fracking, which is a very well understood process, really shocked me and other people who understand oil and gas production. The movie Gasland sure made it look bad. Now that most of it has been de-bunked, you would think that people would calm down, but no, popular belief is what I consider permanently skewed towards hysteria and made up bullsh#t.

The BAD thing about the shale plays has nothing to do with the frack itself. There is no way that fractures propagate from 10,000 feet to a fresh water aquifer. We know this. It is a physical fact. I can go into that for hours if someones needs to have that shown to them.

Most of the shale plays have been drilled without major incident. I grew up inside the Arkoma Basin Woodford Shale gas play, and I remember what it was like. Basically, you have an endless parade of big trucks hauling sand and water around. The flowback water was injected into saltwater disposal wells (something I can also discuss in detail) without any major incidents that I'm aware of.

It takes about 8 wells to drain each square mile drilling and spacing unit in most shale gas plays. Even with the big fracks, they need to be drilled parallel to each other only a few hundred feet apart. To limit surface impacts often many wells are drilled from the same pad. So you get a lot of wells on your property, but in a producing area, this isn't that unusual. The difference is the quantities of sand and water that is being moved about.

The biggest fracks that I've seen used 14 MILLION gallons of water and millions of pounds of sand. It takes hundreds of truckloads to haul that amount of water and sand to each well. That is rough on county roads. It is noisy. It goes on 24 hours a day. It is an industrial activity.

Now if you are lucky enough to own the mineral rights under your land (meaning that a previous owner didn't retain them when you bought the surface), you can become a millionaire overnight. So most landowners are actually pretty happy when a company finds 100 million dollars worth of gas under your farm, and you get 18.75% or more in royalty payments.

After the Arkoma settled down (not much drilling is going on right now due to low gas prices), the trucking and all that has basically stopped.

This is what it is. You cannot look at a gas well on the surface and tell if it is a horizontal well or a vertical well. The only difference is that the accumulation covers large areas, and it does make a big surface impact. Things like holding ponds are temporary in all but a very few circumstances.

I am not aware of any gas getting into the groundwater in the Arkoma Basin play. They did have one problem: The Arbuckle Limestone was too deep in the basin center to economically drill saltwater disposal wells, so they had to truck it 20-30 miles away where the Arbuckle was shallower.

The Arbuckle Group is the oldest and deepest sedimentary rock in the mid-continent and Texas (where it is called the Ellenburger). It is thick, porous, and has been used as a disposal zone since the beginning of time. The Marcellus Shale, in the Appalachian Basin, does not have a suitable disposal zone. That has created huge problems with what to do with not only the flow-back of the frack load water, but also with saltwater, which is naturally produced along with the gas.

That is the only difference between a vertical gas play and the new shale plays: the size of the fracks. Also, since shale gas wells have low permeability, the flowing pressure at the wellhead is much, much, lower than say, a vertical well in the overpressured Springer Sandstone in the deep Anadarko Basin.

Oil and gas activities are normally regulated by the various states. Every state has different geology, and regulations are strict and enforced. In Oklahoma, it is the Oklahoma Corporation Commission. In Texas, it is the Railroad Commission (whose regs are often used, to some extent, in other state regulatory agencies).

There are a lot of regulations. Protecting groundwater is the number one rule.

Here is a map of the subsurface wellbore paths in a one square mile area that I just picked in the Arkoma Woodford play. The colored symbols are the surface locations of the wellheads and production pads..normally only a few acres.


Here is a zoomed out view of the play. Each square is a square mile:


Here is a view of the eastern Anadarko Basin. The horizontal wells show the wellbore path. The normal vertical wells just show a well symbol. there are over 26,000 wells on this map, which is roughly 70 miles by 70 miles. Out of the 26,000 wellbores, over 1200 of them are horizontal. Here is a map of all of the wells:


This map shows only the horizontal wells, all of which have been drilled in the last 5 years, pretty much.


That is it for now. I'm busy. The only thing that I need to add is that oil and gas regulations began to be very strict about groundwater protection in the sixties. The Appalachian Basin has many thousands of cheap, shallow, and often poorly cased gas wells that are still being drilled to this day. Mom and Pop outfits are usually the culprit in pollution cases. The bigger companies, who have the capital to drill 10 million dollar wells, have their own compliance divisions to keep their nose clean.

I can print out maps like this all day. I can even post the casing string diameters and depths next to every single well if you guys feel that you need it.

If you want a lesson on the relevance of hydrostatic pressure, which you really need to have a slight grasp of to understand production, I can talk about that.

I can post maps showing naturally occurring shallow gas, you name it. I do this all day long.

Methane is the main constituent of natural gas, but it is rare to find it as the only component of natural gas production. Even in the overmature areas, you usually get a little ethane in it. Most areas have butane, propane, and heavier constituents. This is one of the ways that you can tell that methane in the groundwater isn't due to natural gas. People don't realize how many areas have always had methane in their groundwater. Read this USGS report:

http://www.usgs.gov/newsroom/article.asp?ID=4053#.VGfMjmMtCUn

Most oil wells produce some natural gas. Some oil wells produce a lot of natural gas.

With gas wells, the only time that you vent gas is when you are completing the well. Not long, but enough to be a concern. If it is a lot of gas, which can create an explosion hazard, it is normally burned (flared).

With gas wells and modern pipelines, methane releases should not be allowed. This is an area which should be improved. The cost wouldn't be significant, and right now, the biggest drillers do not want a black eye.

An area that I find troubling is that most oil wells produce some natural gas. If it is a "significant" amount, you have to plug that well into a natural gas gathering system; a gas pipeline.

There are old areas that were drilled in the fifties with aging pipelines that can leak. The pipeline companies fix anything that will cause an explosion hazard, but what I'm talking about is wells that produce small amounts of methane.

In most areas, you use the associated natural gas to run the pumping unit. The familiar pumpjack. If you don't have any gas you must use electricity or trucked in propane to run the pumping units. Western Kansas oil wells have basically no natural gas and have to use electricity, which is expensive.

So let's say that your well produces 10,000 cubic feet per day. You use half of it or so to run your pumping unit and the rest is vented. Somebody needs to invent a little tank apparatus that collects this gas and then periodically burns it off in one or two small burps each day. 5 mcf is worth 20 bucks per day, so most gas gatherers charge a fat fee to hook it up to a gathering system, and you would also need to buy a compressor to get it into the gathering system, which hopefully is low pressure. No way can most wells afford that.

So the safest way to deal with it is to burn it. The methane is far worse than the CO2 that will be emitted by burning it off.

My wife knows more about that than I do. Air quality controls that, and it would be a good idea to declare venting methane a no-no.

This isn't really a problem with actual gas wells. All of that gas is gathered and sent to the gas purchaser who owns the pipeline system. However there are many oil wells which do vent a little methane each day. By a little, I mean not enough to cause an explosion hazard (whole valleys exploded back in the twenties, when natural gas was just a nuisance). That small amount may be a significant release of methane.

The real problem isn't domestic when it comes to venting natural gas. In the world's giant oil fields, the natural gas is often just burned or vented.

Iran, for example, sits on some of the biggest gas fields on the planet. You have to compress it to LNG if you want to ship it, but otherwise we can't control what these countries do.

As an aside, Iran is an interesting topic. Iran has been well-explored. The big oil and gas fields have been found, and Iran's production is peaking. Since that is the only source of money for the country, they have been converting their transportation fuel to natural gas. I believe that they have the highest number of NG powered vehicles of any country on the planet. They don't want to use that oil, they want to export it for income. Since they are sitting on truly gigantic natural gas fields with no pipeline market, they made the decision to convert their transportation fuel from oil to natural gas.

Look it up. It is an interesting story. We could do the same, here. The U.S. is at the top of oil and gas production on the planet. We are sitting on huge proven natural gas reserves, and right now prices are so low that drilling has almost stopped.

If Iran can switch to natural gas, why can't we? One reason is that people believe all of this bullshit about fracking.

Fracking is still going on, full blast, all over the country.

FYI, here is a compilation of papers on US Methane Leakage from Natural Gas Systems by the Chesapeake Climate Action Network

http://chesapeakeclimate.org/wp/wp-content/uploads/2014/03/Summary-of-methane-leakage-studies_061214.pdf

There are two main approaches that scientists and engineers take [to estimate methane leakage]. The first approach is a bottom up modeling of the different processes in the natural gas lifecycle using, usually EPA, emissions factors. Significant concern has begun to arise, however, that the data in the bottom-up approach is based on engineering calculations and/or approximately measured volumes, and has not been comprehensively measured to verify emissions from a wide variety of wells. As such, there has been increasing attention paid to top-down modeling, which takes aggregated data, such as atmospheric methane measurements, and uses models to determine the sources of these gases. In many cases, the top-down measurements have revealed methane concentrations near gas basins that are several orders of magnitude higher than official estimates based on the bottom up approach.

Nearly all of the researchers from industry, government and academia agree that more data is necessary from all stages of the natural gas lifecycle (except during combustion) and that no one is quite sure how much methane is leaking.

"The BLM is supposed to sort out high-priority wells and inspect all of them. But the GAO found that, between 2009 and 2012, the regulators failed to inspect more than 2,100 of the 3,702 wells they had flagged as high-priority. Inspecting fewer than 60 percent of high-priority wells is not good enough. Meanwhile, inspectors in the field are often armed with obsolete marching orders because the BLM hasn’t updated some of its drilling standards in decades. And the agency has not coordinated enough with state governments to maximize the number of high-priority wells that get looked at by some authority — whether state or federal."

FracFocus is a voluntary program but without it there is no central repository for this information. Being voluntary means it relies on oil industry full disclosure and transparency without any real hammer for inaccuracies.

FracFocus Fails as Fracking Disclosure Tool, Study Finds
By Jim Polson Apr 23, 2013 2:55 PM PT 1 Comment Email Print

FracFocus, the website used by Exxon Mobil Corp. (XOM) and other energy companies to disclose chemicals used in hydraulic fracturing, fails as a compliance tool for the 11 states that rely on it, a Harvard Law School study found.

Using the voluntary registry for compliance with state disclosure requirements is “misplaced or premature” because of spotty reporting, lack of a searchable database and an “overly broad” allowance for trade secrets, according to the study published today by the Environmental Law Program at Harvard.

The U.S. Bureau of Land Management should establish basic requirements for disclosure and penalties should apply for failure to report, according to the study. The online registry was created in April 2011 to keep track of chemicals used in fracking, in which producers shoot a mixture of water, sand and chemicals underground to access oil and natural gas in dense rock formations.

“Any state’s ability to make demands on FracFocus is limited,” Kate Konschnik, Margaret Holden and Alexa Shasteen wrote in the report. “The federal government should step into this void and require minimum standards for the disclosure registry.”

Of the 18 states that require companies to disclose chemicals used in fracking, 11 require or allow the reporting to be on FracFocus. The study cited reporting by Bloomberg News and the New York Times.

FracFocus is operated by two groups: the Ground Water Protection Council, a group of state water officials; and the Interstate Oil and Gas Compact Commission, an association of states that produce the fuels.

“We believe the research done by the Harvard team fails to reflect the true capabilities of the FracFocus system and misrepresents the system’s relationship to state regulatory programs,” the Ground Water Protection Council said in an e- mailed statement.

Since others are giving all due respect to dissenting views, I'll try the same. . .

With all due respect, the arguments I read against fracking boil down usually to the following:

1. Fracking isn't "safe" (meaning that fracking is imperfect); and

2. Fracking, or any other economic activity involving hydrocarbon fuel, is inconsistent with our long-term energy policy.

I think both of the statements above are true (at least as I have defined No. 1), but I find neither statement helpful.

Point 1 merely says that fracking is imperfect. Show me a perfect alternative, and you may have a point. Otherwise, critics of fracking need to compare the advantages and disadvantages of every other option to make valid comparisons.

Point No. 2 ignores the famous dictum of Lord Keynes: "In the long run, we are all dead." The cost of achieving an economy free of hydrocarbon (or at at least fossil) fuels matters in reaching the long-term goal. What gets us there almost certainly differs from what we will need when we arrive. Dismissing fracking - or any other technology providing hydrocarbon extraction - as unnecessary because we won't need it long-term is silly. It's like saying I don't need food to hike the length of the John Muir Trail because there's plenty of food at the end.

Carry on.

I really don't know what to say to you guys without getting really technical. I have read many of those papers, and the quality is often poor.

Most people with the technical background are working in the industry. And nobody will believe them. Do YOU believe them?

I spent about 6 hours yesterday reading the papers on fugitive methane emissions. The Cornell guys are full of it.

I don't drill shale gas wells personally. I do drill the occasional horizontal, though. I've witnessed a fair number of frack jobs, and they don't vent the amount of gas that the Howarth paper claims. Not because methane is bad. Methane from oil and gas activities is a fairly new idea. It can be dealt with without too much trouble once regulations are in place. The notion that shale gas is worse than coal is almost criminally wrong.

All I can say now is that the emissions from venting during flowback are wildly exaggerated. It is a serious fire hazard working in a cloud of methane and air. I've always seen it flared, even on little vertical wells.

The flow lines go through a piece of equipment called a separator. They are cheap. As the flowback water comes back, the gas is separated and flared. The notion that they vent full IP volume for 9 days is lunacy.

I'm so sorry about this. To address some of the most common, and most stupid, allegations, I have to give you a physics and engineering lesson. There is just so much bad info on the web. It is all over the place. I can't keep up with it.

A very interesting article discussing the hazards old wells pose to polluting the groundwater. There are approx. 180,000 abandoned wells in pennsylvania and they don't know where most of them are.

Rather than defining fracking as something that is not perfect. I think you should compare it to a gold rush; would you define the CA gold rush as not being prefect? It just doesn't fit because it is so complex on so many levels.

The heads of CA regulatory group for fracking DOGGR were "let go" in 2011 because they were not issuing permits fast enough. They wanted more time to review possible groundwater issues.

I should mention that during a year consulting at Chesapeake, I saw that they had their own groundwater hydrologists working the Appalachian Basin. They also have a fat compliance division.

I also didn't know this, but they have been drilling groundwater monitoring wells before drilling for quite some time. That way they have proof of original water quality.

DOGGR has provided the State Water Board with information for WD wells fitting the Category 1 description that are located in the east side of Kern County, within the Central Valley Regional Water Quality Control Board’s (Central Valley Water Board’s) jurisdiction. To date, no additional Category 1 WD wells located in other areas of the State have been provided to State Water Board staff. Initially, information for eleven WD wells injecting into clearly non-exempt aquifers was forwarded to State Water Board staff (referred to in the attached table as Category 1A). Staff identified 108 water supply wells located within a one-mile radius of seven of the injection wells. Water supply wells were not identified within a one-mile radius of four of the injection wells. The Central Valley Water Board issued 13267 Orders to the well operators for all eleven of these injection wells, but withdrew the 13267 Orders as to two of those injection wells once it was determined by DOGGR that they were injecting into exempt aquifers. The Central Valley Water Board also conducted sampling of eight water supply wells in the vicinity of some of these Category 1 injection wells. Nitrate, arsenic, and thallium exceeded the Maximum Contaminant Level (MCL) in four of the water samples. The Central Valley Water Board provided the results of these samples to the owners of the supply wells and notified the Kern County Environmental Health Department. TDS exceeded the secondary MCL (SMCL) in 3 samples collected, with maximum concentrations detected at 1,800 ppm.

Although I agree the elevated NO3, As & Tl could be evidence of contamination of a non-exempt aquifer by injection of oilfield wastewater into a nearby Category 1 Waste Disposal injection well, these are preliminary findings form a 60-day investigation, not a comprehensive scientific study. 4 of 8 samples collected from nearby water supply wells exceeded the maximum contaminant levels (MCLs) for NO3 > 45 mg/L; Tl > 2 µg/L and As > 10 µg/L. These are all natural constituents of groundwater, so their presence alone does not prove contamination. Once the new monitoring program required by SB-4 is in place, hopefully oilfield wastewater injection wells that are injecting into non-exempt aquifers will be identified and discontinued.

Nitrate and arsenic in Kern county ground water is a common problem for the area injection wells or not. Arsenic isn't all that rare at all in ground water in the whole southern half of the state, but is particularly present in the southern part of the San Joaquin valley. There are several competing technologies for removing it. As water has become more scarce and expensive it's become economically viable to install removal systems. In the last five years or so there have been a dozen or so removal systems built that I know of in Kern Co. Mesquite NV and the area supplied by the Virgin river also has a problem with naturally occurring arsenic contamination.

Shale gas and fracking Fracking is depleting water supplies in America's driest areas, report shows From Texas to California, drilling for oil and gas is using billions of gallons of water in the country's most drought-prone areas

America's oil and gas rush is depleting water supplies in the driest and most drought-prone areas of the country, from Texas to California, new research has found.

Of the nearly 40,000 oil and gas wells drilled since 2011, three-quarters were located in areas where water is scarce, and 55% were in areas experiencing drought, the report by the Ceres investor network found.

Fracking those wells used 97bn gallons of water, raising new concerns about unforeseen costs of America's energy rush.

"Hydraulic fracturing is increasing competitive pressures for water in some of the country's most water-stressed and drought-ridden regions," said Mindy Lubber, president of the Ceres green investors' network.

Without new tougher regulations on water use, she warned industry could be on a "collision course" with other water users.

"It's a wake-up call," said Prof James Famiglietti, a hydrologist at the University of California, Irvine. "We understand as a country that we need more energy but it is time to have a conversation about what impacts there are, and do our best to try to minimise any damage."

It can take millions of gallons of fresh water to frack a single well, and much of the drilling is tightly concentrated in areas where water is in chronically short supply, or where there have been multi-year droughts.

Half of the 97bn gallons of water was used to frack wells in Texas, which has experienced severe drought for years – and where production is expected to double over the next five years.


Large hoses run from hydraulic fracturing drill sites in Midland, Texas. Fracking uses huge amounts water to free oil and natural gas trapped deep in underground rocks. With fresh water not as plentiful, companies have been looking for ways to recycle their waste. Photograph: Pat Sullivan/AP Farming and cities are still the biggest users of water, the report found. But it warned the added demand for fracking in the Eagle Ford, at the heart of the Texas oil and gas rush, was hitting small, rural communities hard.

"Shale producers are having significant impacts at the county level, especially in smaller rural counties with limited water infrastructure capacity," the report said. "With water use requirements for shale producers in the Eagle Ford already high and expected to double in the coming 10 years, these rural counties can expect severe water stress challenges in the years ahead."

Local aquifer levels in the Eagle Ford formation have dropped by up to 300ft over the last few years.

A number of small communities in Texas oil and gas country have already run out of water or are in danger of running out of water in days, pushed to the brink by a combination of drought and high demand for water for fracking.

Twenty-nine communities across Texas could run out of water in 90 days, according to the Texas commission on environmental quality. Many reservoirs in west Texas are at only 25% capacity.

Nearly all of the wells in Colorado (97%) were located in areas where most of the ground and surface water is already stretched between farming and cities, the report said. It said water demand for fracking in the state was expected to double to 6bn gallons by 2015 – or about twice as much as the entire city of Boulder uses in a year.

In California, where a drought emergency was declared last month, 96% of new oil and gas wells were located in areas where there was already fierce competition for water.

The pattern holds for other regions caught up in the oil and gas rush. Most of the wells in New Mexico, Utah and Wyoming were also located in areas of high water stress, the report said.


Source: Ceres Some oil and gas producers were beginning to recycle water, especially in the Marcellus shale in Pennsylvania, the report said. But it said those savings were too little to offset the huge demand for water for fracking in the coming years.

It can take millions of gallons of fresh water to frack a single well,

Typical hyperbole.

The common unit of measurement for water and wastewater is MGD (millions of gallons per day)

1MGD= about 700 gpm that's so small a well that most water agencies wouldn't even bother drilling one at that capacity.

For some perspective MWD's Colorado aqueduct has a capacity of 861mgd so all of those years of fracking wells amounts to what, 100 days worth of what LA uses?

100 days of what LA uses is more than half of the total Owens Valley aquifer.
And actually, LA takes more than that. Some estimates say LA takes 90% of that watershead's water.

That's 328 days.


The reserves in the aquifer are decreasing, as witnessed by the fall in lake Mono.


So LA would have to be some where's between 3 and 4 Million smaller to keep the status quo in water consumption per capita.


I wouldn't dismiss it so easily.

Yup, Colorado is damned dry too. That shale throughout the Rockies (Colo and Wyo.) ain't gonna dig itself up either. However, people are choosing to drive them pickemup trucks 'cause drinking water is always on tap. So to speak.....


Question: Has anyone here complaining about fracking given up driving their car yet? How about house heat? Turning off all electricity? Yeah......me either. I like it warm, lit up and most important: affordable. I drive a high(er) mileage vehicle, but driving to go climb (a totally self-indulgent thing) makes me pause and consider my role in this issue. Doesn't matter I suppose, we can keep digging coal and burning it for power to keep the Wilbeers of the world (who hate fracking) happy. Till all the damned trees die.

Never noticed it back then, but Lorenzo has LADWP and MWD confused.

The original LA (Owens) Aqueduct has a capacity of 313 mgd.

The second one added another 187 mgd

It's completely separate from MWD's Colorado River system.

I know that when I was working at Chesapeake, they installed baseline groundwater monitoring wells pre-drilling.

They had a small division that wasn't exploration geologists. They were groundwater hydrologists who knew all of the aquifers.

I will say this. There is so much bad info out their on fracking. Even a reasonable person who spends an afternoon on the web can't find the truth.

So I understand the frustration. Unfortunately the frustrations are mainly base on terrible information.

In Oklahoma, there has been tens of thousnds of horizontal stage fracking. I've not heard of a single problem. Like any complicate engineering process, there will be accidents, but modern drilling is far more than poking a hole in the ground.

No. the fractures do not come even close to making it up to the water table. Too much ductile shale in between.

I was really surprised that frack jobs became the focus of attention. There are other things that I would have thought would be worse.

Almost all frack jobs go well. The problem is moving all of that water and sand by truck at the surface, and recovery and disposal of flowback water. Some basins have great deep diposal zones. The Marcellus doesn't have this. That is the only difference in the Marcellus.

I do this for a living, and I don't lie. It is overblown.

There are problems with saltwater in the Mississipi Lime play in northern OK. We are seeing this induced seismicity. Actions are being taken. Wells are being plugged back several hundred feet above crystalline basement rocks.

Interestingly, the first, and biggest, earhthquakes take place in the Hunton de-watering play. The zone is high perm, so isn't fracked. They move a ton of saltwater with the oil, and it required a network of disposal wells. That was the area of the stongest induced earthquakes.

Fracking doesn't cause earthquakes other than super small ones. Too small to be felt.

It is the disposal wells that cause the induced seismicity. Right now trouble wells are being plugged back from Basement, where the quakes happen. Other wells have been reduced in volume injected.

It is a big deal in Oklahoma, but happens in areas where the wells make tons of saltwater. The Mississippi lime has always produced tons of water along with the oil, requiring regular injection wells.

Basically what you are doing is taking water out of the shallower Miss and injected into the underlying Arbuckle Formation.

Exactly; along with all the other problems, like your neighbor selling there farm so you can have a gas well next door. Not only is it an environmental issue it is a social issue.

As I have said numerous times it is another gold (gas/oil) rush and don't you dare get in the way of all that money.

Fracking is causing some magnitude 3 and 4 earthquakes in Alberta and BC.
The only big downside of the whole business is acquiring the water. My company has no disposal issues because we have disposal wells near our major gas plant.
Ground water contamination has probably occurred in a few cases in the US but this would be due to poor surface casing well design and cement jobs. A frac job could never break through to the surface unless there was a major fault running through the entire strat column (highly unlikely) and we would know about its existence beforehand (I think there was a case in England a few years back).

I was at Burning Man a few years back and one guy asked, upon hearing I was from Alberta, what I thought of fracking. I said "Its awesome"

PSP, there is no horizontal fracking play going on in California. I would suspect that some zones in vertical wells need to be fracked, but these are very small. Not the 10 million gallon jobs needed for a 10,000 foot Bakken lateral.

I flew in and out of Denver over the weekend and saw a couple of rigs, but no vast boom. Most people don't know that just NE of Denver and just east of Boulder is the Wattenberg Gas Field. It is a huge gas field that has seen large fracks for the last 45 years.

There have been some small aquifer problems there, most likely the result of casing leaks.

Normally you just run one casing string over the freshwater, sealing it off. Then you drill through your zone with a smaller bit and case and cement it off. Then you selectively perforate the casing across your pay zone. In most of the areas that I work, you drill through maybe a hundred porous zones containing saltwater just to hit a 20 foot thick porous zone that contains oil or gas. This is what the cement job is for: opening up only the producing zone, and not the host of saltwater bearing zones adjacent to it. Modern cement jobs are very high tech and almost always work fine. If they don't, it usually means that you've lost the well and will have to plug it (if anyone wants to know how that is done, just ask).

Right away you need to rid your mind of the notion that induced fractures reach the surface. This is physically impossible.

Any pollution from a producing well is either a spill at the surface equipment, which can happen just like any other accident, or a casing leak that somehow manages to migrate around the annulus of the surface casing cement jobs. Horizontal wells require three cement jobs.

There are cases where this has happened, but if you can't fix it, you have to plug the well. Leaking methane is too dangerous from a fire hazard to allow it to continue.

You see some lawsuits over this. I know of two cases where, in Oklahoma, gas got into the aquifer. What happens next is the operating company gets sued for millions for contaminating the groundwater. No operator wants that to happen, period. A landowner lawsuit can take a small company down.

The worst type of contamination is saltwater getting into the fresh water. There are a number of cases where this has happened, pretty much all a result of wells drilled prior to 1950, when they didn't case off the groundwater completely. Saltwater ruins the aquifer. You see it most often in old oil fields that are undergoing secondary recovery, also known as waterflooding.

Getting a waterflood permit these days is hard in this state. There cannot be any improperly plugged old wells that could provide a conduit to the surface. If you want to go ahead, you have to successfully re-enter the old borehole and set a number of large cement plugs in it.

Groundwater protection is the most serious and enforced regulation that producing states have. They have all seen it in old fields. It isn't difficult to prevent, and it is just another expense, and not a big one at that. It is taken very seriously. The neat thing about groundwater protection is that it is cheap. One surface casing string costs maybe 50 grand. You can set a second, deeper one, for another 50 K. When a well costs 7 million to drill, 100K for groundwater protection is a drop in the bucket.

Modern well construction is highly refined in 2015. Back in 1950, it was crude by today's standards.

Anyway, you can actually monitor a fracking operation in real time, and while it isn't done on every well, it is used fairly frequently.

It is called microseismic, and it is similar to a seismic exploration project, where you lay out thousands of little geophones and then have these giant vibrating trucks shake the ground. That sound then travels deep into the ground and from that you can see folds, faults, even buried river channels 10,000 feet deep and 350 million years old.

With microseismic you listen to the fractures propagate, and then run it through some zillion dollar software on huge computers and you get a picture of every fracture as it propagates. The goal is to fracture the target zone, which is usually a particular organic rich shale, such as the Barnett, Woodford, Haynesville, or whatever. Most of these are Devonian black shales that are high in organic carbon. Their thickness varies. The Woodford can be 100 feet thick or 500 feet thick depending on what part of the basin you are drilling in. They are deep, too. Normally over 8000 feet (this has to do with thermal maturity which is another topic), where the shale is in the gas or oil window.

Anyway, I've seen a fair number of microseismic sets, and I've never seen a fracture more than a couple of hundred feet out of the zone. The reason is simple. These shales are high in silica, and you can think of them as ultra fine grained sandstones. The normal shales above them are clay rich and ductile. You can't frack that if you even tried. The target shale has to be brittle enough to frack, and often these Devonian shales are, at least in part brittle. Just go to Wiki and read about Young's modulus or Poisson's Ratio for the basics that you need to effectively recover gas from a shale.

PSP brought up the topic of water. This is a big deal in some areas, and not in wetter areas. I'll give you an example of what is starting to happen: Continental Resources is fracking the snot out of the Woodford in SW and S Central OK right now. They have built two recycling plants to re-use water. You don't need drinking quality of water to frack a well. Actually, fresh water is bad, because it can cause certain shale minerals to swell, sealing off flow paths. So you add KCL to the water to bring the salinity up to a safe level. You can frack limestones with fresh water, but in clastic systems you must add enough KCL to bring it up to about 3%. To protect against swelling clays.

Anyway, Continental is drilling this area up like crazy and is recycling the water, because it is a big expense. I believe that this has been going on in the Marcellus, but up there there are so many different companies, that it becomes more difficult. It is being done now in certain places, though.

Great scientfic debate regarding the facts of fracking on, RT.com

Sounds like those Frackers are holding on tight to their Willful-Ignorance!

They argue that there isn't enough substantial evidence proving that fracking is turning drinking water brown, or causing earthquakes. Their denying argument is is obliviously a ploy to continue kicking the debate down the road while they keep on making their Billion dollars a day. Who are these deniers Shell, BP,etc. they're not even American owned company's. Yet they say their helping the USA be less dependent on foreign fuel. But that's not even true. 80% of the fuel America produces goes to Texas and is sold on the world market. Then there's the whole "it's making more jobs" speel, another job well done by the lobbyist of throwing a little money at the sheeple to keep a blind eye.

[quote]Frack!

I don't know enough about hydrofracturing to get oil out of the ground to determine whether it is alright or not. But injecting chemicals into the ground to aid it? That is nuts.

http://www.nytimes.com/2011/04/17/science/earth/17gas.html

WASHINGTON — Oil and gas companies injected hundreds of millions of gallons of hazardous or carcinogenic chemicals into wells in more than 13 states from 2005 to 2009, according to an investigation by Congressional Democrats.


Companies injected large amounts of other hazardous chemicals, including 11.4 million gallons of fluids containing at least one of the toxic or carcinogenic B.T.E.X. chemicals — benzene, toluene, xylene and ethylbenzene. The companies used the highest volume of fluids containing one or more carcinogens in Colorado, Oklahoma and Texas.

Millions of dollars have been spent remediating older leaking underground storage tanks used at gasoline stations. the primary contaminants were BTEX.

I reposted my first post.

I am not basing this on fear. I have spent 25 years cleaning up the worst waste sites in the USA. 10 different states, multiple different superfund sites including radioactive waste and nerve agents. Multiple groundwater pump and treat systems from Connecticut to New Jersey to Nebraska and Utah.

This is how the general public now perceives fracking. There is so much bad info out there that it is, and I've said it before, nigh impossible for even an intelligent person, to understand the truth and how it works.

First, "in the ground" makes it sound like it is just pumping it into the dirt beneath your feet. This is a gross mischaracterization.

The zones are deep. Usually between 8000 and 13000 feet deep. 5000 is the shallowest depth that I know of for a horizontal play.

The zones are discrete. Above them lie a mile or two of younger rocks, mainly shale. It is not possible to frack normal, ductile, clay rich shale. The organic rich, mainly Devonian black shales are not typical shales. The zones that are targeted need a high silica content to make them brittle. If you steer the wellbore above or below the brittle layers, which are generally relatively thin, 100 feet or so feet thick, if the perforations in the casing are not in the brittle layers, you can pump on it all day long at 10,000 psi and never be able to break the rock. It is too plastic.

So it isn't like a leaky gas tank at your local convenience store. Those tanks are literally in the ground. 20 feet or less deep. They leak into the aquifer, which is shallow. Pulling leaky tanks was a huge boon for environmental companies, and they did zillions of those tanks back in the 80's.

Fracking takes place in an entirely different environment than "in the ground."

Here is a snippet of a well log showing the Woodford Shale, which is the main target in SE and SW Oklahoma. To show the entire section of overlying Mississippian, Pennsylvanian, and Permian rocks would be way too long to post in this format.

If anyone is interested, I can email you a log showing how much rock sits on top of them. The Woodford is overlain by numerous zones which produce oil and gas in their own right. They are drilling horizontals beneath conventional oil and gas fields.

It is illegal to dispose of hazardous waste in injection wells in the oil and gas industry. That said, crude oil that is in a tank next to a pumping unit that you might see when you drive across the country contains Benzene and other nasties, just like the gasoline that you put in your car is filled with nasties. The EPA doesn't regulate produced product. The states do that.

Here is a log showing the Woodford Shale. It is overlain by the Caney Shale, which is too ductile to fracture even if you wanted to. It is underlain by the Hunton Group, which is one of the main producing zones in Oklahoma. The Woodford is colored yellow. A horizontal must be steered to stay in the Woodford, which in this case is a thin target:

The discussion on this thread reminds me of an incident that I observed 43 years ago in Berkeley. We were vacating our apartment and decided to throw a going away party. The metal door jambs provided a perfect medium for doing fingertip pullups. There were several young climbers (and several attractive young women) there, and as the climbers were on their way to getting hammered, they started doing a fingertip pullup contest (obviously in full view of the young women).

The first one did four. Eventually the high was six. About that time my roommate, still sober, proceeded to rattle off 15. When he left, the group resumed "Seven! Can anyone do seven?" Lest you think this was just a bunch of wimps, several of those participating went on to find glory in the Valley, Meadows and elsewhere.

BASE104 provides solid facts, which, like my roommate's 15 pullups, get ignored. Everyone goes back to repeating their quasi-religious nonsense about the topic. If nothing else, it forms an interesting insight into human nature.

IMO Oil and mining business as usual has been out of the public view; because usually it is in remote areas. The new fracking isn't remote it is in the neighbor hood next door to farms infiltrating small towns that never had oil business. And big oil is so clueless they think their "standard practice "in remote areas is OK in residential areas because they are blind to the residential concerns.
an example would be lowering the local water table to do their fracking. Or setting up shop next to a farm where it used to be quiet and now the quiet is gone.

Now add on top of it that they are carting around large volumes of haz waste and taking the haz waste to other states that have more lax laws to inject it there .

It just isn't meant to mix with the general public; and hasn't been addressed or scrutinized by the general public until they decided to try to change the landscapes in Pennsylvania and many other places in the US.Now their "standard practices" are being exposed and the general public is surprised they can do crazy sh#t like injecting haz waste deep into the ground.

reminds me of when the gold miners filled the sacramento with sediment from the hydro mining and finally the public had to make laws against it.

Fracking is no big deal,and lots of the produced water that gets injected back down is shitty to begin with, and has been for decades. The real problem with O&G exploration is air- they split emissions up to avoid the 10 tons per year NESHAP requirements, and water- they avoid water use restrictions (typically a state issue) and the clean water act, which exempts O&G from tons of requirements. CERCLA also includes the famous petroleum exclusion, meaninig your standard historical tank farm sh#t show is exempt from federal cleanup laws, leaving the generally poor surrounding landowners to resort to innefective state tort law to obtain any relief. Often after decades of expensive litigation. Produced water management companies illegally dispose of water all of the time. If it were all left to engineers like Base we would have few problems, but it is not.

Oil is what it is, but there is a very real human and environmental cost. Maybe it is worth it but the real impacts should be considered. I think what really has happened is that the general public is being exposed to what goes on to extract oil and gas in their own neighborhoods.

I remember in the 70s the same argument being made, loudly and widely, against the Alaska pipeline. It was going to be "environmental Armageddon" if it was built. There is no free ride and there is environmental destruction in ALL energy applications/resource extraction. ALL.

To illustrate this, I will add one example from this state as it relates to wind. Not long after it was up and spinning, I learned that the North Powder wind farm in Eastern Oregon alone had killed well over 60 Golden Eagles. That they know of. 60. The blades whack them right out of the sky. How many uncounted dead ones are hauled away by Coyotes (and Wolves) from the fields in the night? How many are injured and manage to die further afield? Unknown. But it is a factor. How many bat and other species will be exterminated by wind? Unknown, but it indiscriminately kills them as well. Who here wants to tell their children: "OH, YEAH WE EXTERMINATED THAT SPECIES OF BIRD SO WE COULD HAVE WIND POWER". Is this something anyone would want? Uhh, no. This single point should illustrate that wind ain't free of side effects and bullshit that your kids will be paying for either, you have to pay the price for energy. ALL energy.

Given the way regulators have been whacked around by all the federal courts for failing to follow proper procedure the last couple of years, the ruling on the EPA mercury rules did not surprise me, Moosedrool. The EPA said cost was irrelevant, so it made no finding on the cost of the regulation. Even then, four justices said its regulations were OK. Not so long ago, the EPA was slapped down 9-0. If it had simply found that the benefits exceed the costs, it would have won at the SCOTUS.

All this decision accomplished was a slight delay, and providing regulatory agencies with a roadmap for making rules impervious to challenges. As long as the regulators stop being arrogant and simply follow the rules, making findings they don't consider, but Congress requires them to make, they can still accomplish what the want.

Reactions from guys like Studly above...who has no idea how the process works, the risks, the engineering..well, I don't really get too upset over it. If you just go to Youtube and type in "fracking," you will immediately see reams of baloney. There is so much disinformation out there that I keep saying even a reasonably intelligent person can't find the basic truth. So getting into a bickering match is pointless.

Myself, I actually make very little of my money off of the horizontal plays. I have a few royalty interests in leases that were producing from conventional vertical wells, and then a company comes in and drills deeper to the Woodford. I make only a few hundred bucks a month off of it.

I have been doing conventional vertical wells that needed fracking for my entire career, though. Some producing zones have low permeability, and they have been fracked since 1950. The zones which produce from high permeability zones don't need a frac. I'd guess that 75% of the reserves that I've found needed a frac job. It was nothing new. Tens of thousands of wells all over the state have been fracked.

Somehow the anti-oil folks latched on to fracking. It was surprising at first. Why suddenly fracking became such a big deal. The only difference with the fracked horizontals is the size of the frack. With a vertical well, you can only frack around the 8 inch borehole. With horizontals, you perforate "stages" along the wellbore. Every 100-300 feet. If the lateral is a mile long, then it is like drilling 20 or 30 vertical wells with a single wellbore. The shales are too low perm to produce economically out of a single wellbore in almost all circumstances, but the technique can be used in conventional zones if the stars align. I've done that.

The thing that I don't like about drilling and producing is the scar it leaves on the land. In the mid-continent, you are usually drilling in wheat or corn. That land has already been totally destroyed by man. You should see SW Kansas. It is an ocean of center pivot irrigation, and it is hard to find a weed. The land has been plowed, terraced, and turned into monoculture. The grasslands are gone. Why people don't get riled up about that confounds me.

A well pad is usually small. After the well is plugged, you can't tell where it even was. In areas like the arid west, the roads, pipeline right of ways, and producing pads are visible from the air if you have ever flown over it. That bugs me. Fracking? No.

You guys seem to think that somehow induced fractures climb all the way to the surface. This is baldly false.

To get to the Woodford Shale, for example, you have to drill through (in the Anadarko Basin), a couple of thousand feet of anhydrite and gypsum. Then you drill through maybe a hundred zones that contain saltwater, separated by clay rich ductile shale. You can't frack that rock even if you tried.

I keep up on it, though. These Devonian shales have intervals that are quartz rich and brittle. You have to steer the well through those zones or the well will be a dud. The gas is trapped in the shale through capillary pressure, unlike the high perm zones above and beneath it. If you get out of that target interval, you can pump on it day and night and it won't fracture. The rock properties have to be just right. A well's success is often gauged by how many of the separate frack stages that successfully injected the proppant, normally sand.

Anyway, drilling for natural gas is not very lucrative with today's glut and prices. Most of the attention is towards wells that produce oil or condensate.

Nobody asked for a well log! An entire well's log is about 30 feet long, so I can only post snippets here. I can email you one, though, just so you guys can see the geological setting of these zones.

BASE is adding very insightful information to this discussion.

For fun (and because I love talking about fracking with people who generally are curious about it), I created a *very* elementary sense of scale for how deep these wells are. The point being is that even if you had a freshwater aquifer 1000 feet deep, you still have a looooong way to go before you hit that 50 foot payzone where all the fracking is taking place.

This first one is your typical human with three sizes of casing for scale. I'm an amateur at Google Sketchup, but these are roughly to scale:


Next, let's look at your typical drilling rig and assume that it's 100 feet tall - usually taller, but let's keep things simple:


Now down to the bottom of the surface casing, which is usually around 26" in diameter, and is usually drilled through the water table to avoid further contamination - let's say 120 feet in this case:


Now let's get confused and switch the view to 3D for a better idea of hwo big the rig is and how deep just the surface casing is:


Now down to 2000 feet:


Now to 10,000 feet:


That gray rectangle is a 1650' x 2000' area on the ground-surface.

The point being, these wells are DEEP. It's next to impossible a frack job would propagate anywhere near the surface.

Then again, I'm just a brainwashed industry worker....

High pressure toxic fluid injection plus imperfect knowledge of cracks and weaknesses in the rock layers between the injection site and the water table, and the imperfect ability to engineer systems according to design over a large number of iterations, leaves a lot of room for "oops" moments. It seems quite a bit of hubris to assume we can control all the variables well enough, to not just mitigate, but to "prevent" accidents.

In my totally unrelated field (but within the realm of engineering), there is a big gap between the theoretical resiliency in a system and how it will perform, versus what happens in reality on a large scale when "the human element" is introduced- testplans are not followed accurately, people cut corners to make deadlines or reduce costs, etc....

In this case, accidents or unforeseen elements can render many communities without usable drinking water, or worse, have that happen without public awareness and not detected until long term negative effects are observed.

So yeah, I do think that workers who make money in the industry are brainwashed. I would be if my livelihood depended on it.

So then what is the alternative to fracking?

Am I brainwashed? Probably. But realize that there is an enormous scientific community within oil and gas. The amount of research that goes into every well, field, region to best understand the subsurface is very significant. This isn’t a “Hey Cletus, go put them thurr frack chemicals down in that hole over yonder” type situation. It’s in an operator’s best interest NOT to contaminate the water table, and thousands of man-hours go into the research behind where to dispose of fluid or how to best drill/frack a well.

Consider that you may be dismissing and/or underestimating the science behind drilling and fracking in the same way that a fervent climate-change denier dismisses the science behind global warming. That much is apparent by some of the responses in this thread…

One notion that I try to explain to people is that these layers of rock that contain the natural gas and oil are isolated. By that I mean that they are confined by many stratigraphic layers above that act as a seal to contain the oil and gas. Otherwise they would have seeped to the surface millions of years ago. The majority of accidents (that I DO acknowledge happen due to human error) occur at the surface, most often with the improper storage or spilling of fluids. In my opinion, some serious regulation and oversight is necessary to help alleviate these accidents.

Yes, the industry is driven by $$$, but what isn’t in this country? What is the alternative to fracking? Do we just stop it completely (although fracking has already lurched to a crawl currently), so we can keep shipping in millions of barrels a day from OPEC producers to satisfy our thirst for hydrocarbons?

Research renewables you say? Do you think that isn’t happening right now? The technology just isn’t there yet to satisfy our enormous energy needs. Until the next solution is developed, we’re stuck with oil and gas. I say increase regulation and oversight. If we’re going to do it, make the information public. People have the right to know about environmental accidents and violations. Companies should be required to disclose what chemicals they’re adding to a frack fluid. If we’re going to do it, we should be doing it right.

If you do look around though, progress is being made. The current glut of oil shows that. People are becoming more energy conscious – driving better MPG (or electric) cars, buying energy-saving appliances, adding solar panels to homes and businesses to reduce reliance from the grid – it’s happening, albeit slowly.

Like other folks have said, natural gas is at least much environmentally friendlier than coal. Can you at least admit that?

I know I won’t convince anyone who has already made up their minds that a group of evil-grinning Dick Cheneys and Daniel Plainviews are sitting around a table maliciously plotting the intentional widespread destruction of our most valuable resource (water) whilst sitting among their fat stacks of cash. Okay, maybe to some extent, but not as bad as some are painting it... But I do hope you do a little more research into the side you oppose. Fracking might not be as destructive as it seems to be… Compared to the alternatives at least.

Do I wish we didn’t have to rely on it so much? You bet! Like everyone else on this forum, I care deeply about the pristine environments we all enjoy so much. Unfortunately, I think oil and gas is a necessary evil that keeps the gears of this country turning. Let’s just try and make it less evil?

For the last 7 years I have been working on the mother of all environmental clean up projects at the Hanford site, the most costly remediation project in the world, well over $100 BILLION.

jfailing, I appreciate the measured rational response.

I'm not against the concept of fracking entirely, but it is something that should be highly transparent and highly regulated to protect communities because the cost of a screw-up is so high. I don't understand the economics enough to know how much independent data gathering, checkpoint/oversight and regulatory compliance costs would affect the profitability of the endeavor. But there should be full disclosure with community buy-in (which is admittedly a political/marketing nightmare, but perhaps rightly so given the cost of failure) built into the modeling for how profitable it is to pursue these energy reserves in a manner that is sufficiently safe for the affected communities.

Maybe a good requirement would be for all executives of the companies making a profit from the fracking process should be required to use the local tap water for all of their families' water needs ;) Not really practical to enforce this, but nice idea!

A tricky part of it is ensuring the true independence of the oversight, rather than government cronies rotating in and out of executive positions in the companies they are regulating (like the FDA).

Anyway, back to fracking. Mad Dog has it correct about Coal upthread. Coal burned to make electricity produces 71 percent of all of the CO2 the US adds to the world right now. Fracking and natural gas usage has been significantly better for the worlds environment than coal. If you could cut fracking to zero, you'd be screwing up the envronment real bad as coal would be the replacement fuel. Until now. MIT appears to have some good news on coal right here: https://stream.org/mit-finds-way-make-coal-twice-green/

I don't know what "twice as green" means. Is that like a laundry detergent promising to make your shirts "Whiter than white". What is that? When you follow the link you get a more sensible statement:
..."researchers at MIT have come up with a plan that could contribute to that effort by making it possible to generate electricity from coal with much greater efficiency — possibly reaching as much as twice the fuel-to-electricity efficiency of today’s conventional coal plants. This would mean, all things being equal, a 50 percent reduction in carbon dioxide emissions for a given amount of power produced."


Great news. We should be able to sell the technology to China and other heavy polluters if it's a viable thing. Certainly will get our nasty coal emissions down as well.

It seems quite a bit of hubris to assume we can control all the variables well enough, to not just mitigate, but to "prevent" accidents.

Man. You guys just have no concept of the depth of these wells and what happens during a fracking operation. I'll try to summarize it.

First, if you drive up to a well head, you will have no idea if it was fracked or not, or if it is a vertical or horizontal well. The vast majority of these wells are well over 8000 feet deep. The notion that you are somehow exploding the ground beneath your feet is just hogwash.

First, there is no real difference between a vertical fracked well and a horizontal fracked well, other than volume injected. In most areas, all wells need to be fracked, and have been for 75 years or something like that.

You drill down vertically until you are about 500 feet above your target interval. Then you rapidly build a turn from vertical to horizontal, and if you do it right, you "land" the wellbore right in the target horizon, which is very specific. Above that inverval is thousands and thousands of feet of normal shale, sandstones, and limestones. The porous sandstones and limestones are full of saltwater or hydrocarbons. The horizontal wells target a very specific layer of rock. For this discussion I will confine the discussion to shales.

Shales are the most common type of sedimentary rock. In most sedimentary basins, 90% of the rock you drill through is shale. So why don't you frack all of that shale? Because it doesn't contain hydrocarbons first, and second because the shales are clay rich and ductile. You can pump into that stuff forever and never be able to frack it.

The target shales are generally the specific organic carbon rich shales which source all of the oil and gas in the entire basin, and their thickness varies from 50 to 400 or so feet thick. They have to not only contain hydrocarbons, but they must also be brittle. That generally means that they are quartz rich. Just like a sandstone, except the grain size is far smaller. If it isn't brittle, it won't frack. You can pump into it until the cows come home and it won't fracture.

So understand that the targets are specific zones, and only contain recoverable hydrocarbons if they are deep enough to be thermally mature. Typically over 10,000 feet deep. You still have to carefully steer the bit so that the wellbore stays within a brittle zone, which is typically a quarter or so as thick as the entire target shale (which I already said is usually a few hundred feet thick).

The fractures do not extend very far above or below the brittle target interval. You simply can't fracture those overlying shales, even if you tried. The federal government actually experimented with using nuclear weapons to frack a few wells (one of which is near Rifle, CO). The nukes didn't work.

Why do you drill horizontal wells? A: Because the zone has very low permeability, and a single vertical would barely produce. With horizontals, you selectively perforate your casing every hundred feet or so along the length of the lateral, which is usually 5000 to 10,000 feet long. It is like having 60 vertical wells, with each perforation being the equivalent of a single vertical well.

I've been out on quite a few frack jobs and it works like this: You have portable tanks containing millions of gallons of water, and sand trucks containing hundreds of thousands of pounds of sand. You have already perforated the production liner before the frack boys show up. You isolate each stage along the horizontal, and each stage is like a separate frack. The goal being to not only induce fractures and improve permeability, but to displace the proppant (typically a very particular type of sand, or ceramic beads). The frack stage is successful if you are able to displace all of the proppant into the stage. Out of 60 or so stages, some of them were not steered properly and for some reason or other, you can't fracture a particular stage. The failure to inject the sand is usually because that perforated cluster is outside of the targeted brittle layer. If you don't properly steer the horizontal, it simply won't fracture. If it has too much clay, it won't fracture.

If you rupture your casing, you will immediately see a spike in the annular pressure behind that casing string, and you stop right there. When that happens, which isn't common. You just lost the well. Casing integrity is very important, and horizontals have an additional 1 or 2 strings compared to a vertical.

Anyway, from a seat in the command trailer, you get to see all of the pressure readings. Sensor gauges are attached to the annulus of each casing string. They begin pumping, and you watch the pressure climb. At a certain point you will see the pressure fall, and this means that the formation just began to fracture. You then pump the sand and water slurry into that casing liner at a high rate until you have displaced all of the sand for that stage.

Then you release and reset your packers and move back and isolate the next cluster of perforations and frack that stage. You repeat this until each stage has been fracked. The success or failure is pretty much known right away. How many stages were you successfully able to displace the proppant into...

After you are finished with the last stage, you rig down the frack pump trucks and immediately open the well and allow the water to flow back, typically under its own pressure.

I spent a year as an in house consulting geologist for one of the most prolific fracking companies, although the area I was working didn't require fracks.

To see how much volume of the target shale you have successfully fractured, an important point in frack design, you use microseismic technology now and then. I've seen a number of these datasets. What they are is similar to active seismic. You lay out an array of geophones and record the noise of the fractures propagating through the rock. It is then processed through supercomputers and you get a nice 3D picture of where each fracture went. I've never seen a fracture get more than 100 feet out of zone. Again. That is because these targeted carbon rich brittle shales will fracture, but normal clay rich shales above and below are too ductile to fracture.

The microseismic sets are pretty cool. We had a conference room where you could put on a 3D virtual headset and wave your hands around the dataset with the reservoir engineers. The objective is to fracture as much of that brittle shale as possible. Despite the huge amounts of water and sand, a lateral normally fractures only a few hundred feet laterally, so it takes a lot of horizontals to effectively drain the reservoir and recover the hydrocarbons (typically gas, but not always). Anyway, you could see the lateral and little dots around the wellbore showing each fracture.

You don't do this on every well. It is a reservoir engineering tool only.

The company I worked for drilled fresh water montitoring wells before drilling any horizontal fracked wells, just to cover their ass from all of the baloney being published. They had an entire groundwater division.

They never had a problem, but there were a few spills, almost always either water or saltwater from the reservoir. This was a handful out of tens of thousands of wells.

On groundwater: Fresh water is normally super shallow in terms of oil and gas drilling. Rarely does it exceed 500 feet in depth, and at least in the Appalachian Basin, commonly contained methane from shallow coal seams. Hell, there is a town in Pennsylvanian called Burning Springs if that gives you an idea.

In my area, the mid-continent, the usual shale target is the Woodford Shale. A very specific ealy Mississippian carbon rich shale. The Woodford sourced almost all of the oil and gas in conventional reservoirs in Oklahoma, Kansas, and the Texas Panhandle. It is high in organic carbon, and has been buried deep enough to be thermally mature enough to generate both oil and natural gas.

The Woodfod has been drilled up in the Arkoma Basin in the SE part of the state. I'm not aware of any groundwater contamination, period, out of tens of thousands of fracked wells.

The Woodford has also been fracked in the eastern Anadarko Basin, and I'm unaware of any problems. Nothing made the newspaper, anyway. I've been to some very expensive seminars on the Woodford and understand it well. Nowadays, they are recycling the flowback frack water and re-using it. It is a nice and tidy operation.

They have found so much natural gas that there will be a supply glut throughout my lifetime. It takes 8 horizontals to drain a single square mile section, and there are thousands of sections with only a single well on them, to hold the leases by production. There are 7 increased density wells per section to be drilled some day when natural gas prices recover.

These days, companies have been changing their completions and limit fugitive methane emissions through "green" completions, where they test the well down the sales line instead of venting or flaring gas during the completion.

In the Anadarko Basin, you have to drill through the Springer Sandstone series on the way down to the normally pressured Woodford. The Springer is often over pressured, and if you aren't careful, you can blow out. A couple of wells have blown out and burned the derricks to the ground from stray Springer sands that weren't expected.

There is a lot more science than I can express in this format. You guys would really need to come hang out with me and allow me to walk you through the gas fields on my computer system. After a couple of weeks, you would learn the very basics about how oil and gas accumulate and are recovered.

Ed works for Livermore. They designed most of our nukes. Even if he was allowed to discuss it here, it would be hard to teach the basics of what he does. I have the same problem, but worse. I have to deal with reams of bullshit that people have been making up for the past ten years.

A reasonably intelligent person would find it almost impossible to learn the actual truth about how fracking works just from using Google. I see big publications getting it wrong. Like the New York Times.

It is actually a pretty simple operation, but it is pretty much hopeless. I can't get through to you guys because there is so much garbage information out there. Journalists never get it right, even good ones.

So I forgive your ignorance. It is almost impossible to find out the truth about how fracking works, how safe it is, and all that. So I toss up my hands and give up.

Can anybody point to a good outcome with groundwater aguifers after and area has been fracked?

That one is easy. Everywhere. Groundwater contamination is extremely rare in modern wells. Groundwater pollution normally takes place in old oil fields that were drilled pre-1960. They didn't even case off the fresh water.

You would go to prison if you did that in Oklahoma these days, or at the least pay a huge fine.

The thing that companies fear most is a landowner lawsuit. They can cost millions if you screw up an aquifer. Protecting fresh water is a very simple and cheap part of drilling any modern well.

Show me a place where there is widespread contamination from modern fracked wells. And no baloney youtube videos.

Most groundwater pollution from oil and gas activities is from saltwater getting into the fresh water. Gas contamination of an aquifer is really rare. I'm aware of 2 modern cases in Oklahoma. Saltwater is by far the most common pollutant.

I posted above that one company I consulted for drilled freshwater monitoring wells before any fracking operations just to keep the crazies away. They could drill them for less than 20 grand, which is nothing when your well cost is over 5 million per well. Naturally occurring methane in groundwater is actually reasonably common in hydrocarbon basins. I can show you oil and gas at 300 feet in two areas that I've worked. 300 feet is crazy shallow for oil and gas, which is usually found much deeper, miles beneath the fresh water, which is shallow.

Deeper zones commonly contain water, but it is naturally occurring saltwater. Hitting saltwater instead of oil is the most common type of dry hole.

JFailing wrote a pretty good post above.

I'm getting ready to recomplete an old gas well. The gas zone is 15 feet thick, 4500 feet deep, and depleted. There are 2 oil zones above it that the Operator missed. One is 8 feet thick and one is 5 feet thick. Above those two zones are about 100 porous zones, all of which contain saltwater.

You selectively perforate your cemented casing right at the producing zone. This prevents the ocean of saltwater from getting into your well and ruining it, forcing you to plug and abandon it.

Petroleum Engineer here. (I know I'm going to get downvoted to hell)

The techniques used in hydraulic fracturing (fracking) are designed to mitigate the communication of frac water (which may or may not contain certain chemicals depending on the formation you're attempting to fracture)

Fracturing is generally only done in formations with significant depth to make the emergence of frac water into formations with potable water unlikely. It is also usually done in formations with so called 'cap rocks' above and below which are more or less impermeable to fluids due to their dense structure. We are also able to tell via math and science if any of our frac water has migrated between formations due to changes in pressure and flowrate as we monitor frac jobs.

Now, there are chemical contamination that can occur, but it's usually a case of a faulty casing / cement job in the vertical (read shallow) portion of the well. This is what really needs to be avoided, but the same things happen in wells that aren't even fractured.

I'm an engineer, but I'm also a climber, and a lover of nature. I don't want to see contamination of our vital resources more than any of you, but I also know that when done correctly, the process of hydraulic fracturing is safe.

To give you an idea, the Woodford Shale, the main shale gas target in the mid-continent is colored yellow on this section of a Dual Induction Laterlog.

It is less than 50 feet thick in this well, and is at a depth of 3900 feet.

Overlaying it is the Caney Shale, which is too clay rich to frack. Above that and not shown is the Pennsylvanian section, which is mainly sequences of sandstone and shale. Every layer has a name. Above the Caney is the Bartlesville Sandstone (saltwater bearing), Red Fork Sandstone (saltwater bearing), Upper and Lower Skinner (also "wet"), Prue Sandstone (wet) and then the Cleveland and shallower Virgilian zones, each of which has a name and many of which produce here and there. All of the overlying carboniferous zones require a frack on vertical wells, and have been fracked for decades.

You can drill a ten thousand foot well, passing through ductile shales, saltwater bearing sandstones, evaporate sequences, and other zones for the overlying 3800 feet.

And this is an absurdly shallow well.

I look at the squiggly lines all day long, every day. I don't even see the curves anymore. I see shale, sandstone, limestone, whether one or more has hydrocarbons, whether it is recoverable, etc.

The notion that Fracking is destroying the groundwater is a bunch of hogwash. Yes, it is an industrial process. Yes, accidents can happen. Rarely is there significant, if any, contamination.

When this all started, I expected some flack, because a frack involves a ton of trucking of sand and water to the location. I never thought that fracking itself would be controversial. We are very familiar with the process. Most of the wells I've drilled in my career were fracked. Plain old vertical oil and gas wells.

Now and then I get good enough permeability to get by without a frack, but they increase permeability in the target rock and a 5 bbl/day well might make 200 bopd if fracked. It just depends on the rock and the area.

So when people talk of injecting into the "ground," this is a bit of a misnomer. Yes, they are beneath the surface, but they are at great depth and a typical target is less than 20 feet thick. The zones are even thinner in Kansas. You might drill a well a mile deep looking for oil in a 3 foot thick Marmaton or Cherokee zone. The overlying zones are filled with saltwater. They are cased and cemented off. You perforate the casing right at your zone, so you can isolate it and just produce oil. These are a little more complicated than a hole in the ground.

People don't realize how big a producer the U.S. is. We are one of the top oil and gas producing countries in the world. The problem is that we are 5% of the world population and use 25% of the oil.

And boy do we waste it. Bottled water costs an order of magnitude more than oil right now. As long as it is cheap, alternatives will fail. They can't compete with cheap oil.

I've always been in favor of a carbon tax. It is the only way to make alternatives economically competitive.

Look at Iran. They are fairly mature, meaning most of their oil has been found. They also sit on some of the biggest gas fields on Earth, with no market. To make money from exports, they have begun using methane as an alternative to oil, and they are now the biggest users of methane as a transportation fuel on the planet. We would do well to copy that, because we are swimming in cheap gas, and will be throughout my lifetime.

Use it as a bridge fuel until something better shows up. Natural gas vehicles are much cleaner and cheaper to operate. The problem is that you only get half as much distance on a tank compared to oil. Since little pipeline distribution is present, filling stations are rare. That is why you see fleet vehicles that don't stray far using natural gas as a fuel.

If we just converted our trucking to natural gas, it would go far towards cleaning things up. It is the cleanest burning fossil fuel by far. There is so much remaining shale gas that it would blow your mind. Again, you would have to come hang out with me and let me show you how it works. Most of the shale accumulations have been figured out by now, and their boundaries are known. The increased density wells are just sitting there waiting to be drilled, and there are thousands of them.

Right now, all natual gas drilling has pretty much halted. It isn't worth much. It forced a change in focus to liquids, and then we found too much of that. So now prices are in the toilet.

The oil business is incredibly cyclic. A geologist buddy of mine now makes most of his money playing natural gas options, and does well. It is too cheap to drill for, though.

Impact to Underground Sources of Drinking Water and Domestic
Wells from Production Well Stimulation and Completion Practices in
the Pavillion, Wyoming, Field

Dominic C. DiGiulio*,† and Robert B. Jackson†,‡,§

Stanford, California 94305, United States

DOI: 10.1021/acs.est.5b04970


ABSTRACT: A comprehensive analysis of all publicly available
data and reports was conducted to evaluate impact to
Underground Sources of Drinking Water (USDWs) as a result
of acid stimulation and hydraulic fracturing in the Pavillion, WY,
Field. Although injection of stimulation fluids into USDWs in the
Pavillion Field was documented by EPA, potential impact to
USDWs at the depths of stimulation as a result of this activity
was not previously evaluated. Concentrations of major ions in
produced water samples outside expected levels in the Wind
River Formation, leakoff of stimulation fluids into formation
media, and likely loss of zonal isolation during stimulation at
several production wells, indicates that impact to USDWs has
occurred. Detection of organic compounds used for well
stimulation in samples from two monitoring wells installed by
EPA, plus anomalies in major ion concentrations in water from one of these monitoring wells, provide additional evidence of impact to USDWs and indicate upward solute migration to depths of current groundwater use. Detections of diesel range
organics and other organic compounds in domestic wells < 600 m from unlined
pits used prior to the mid-1990s to dispose diesel-fuel based drilling mud
and production fluids suggest impact to domestic wells as a result of legacy
pit disposal practices.

That one is easy. Everywhere. Groundwater contamination is extremely rare in modern wells. Groundwater pollution normally takes place in old oil fields that were drilled pre-1960. They didn't even case off the fresh water.

I guess my question was confusing. I means a good outcome for the Aquifer and its historic users, not for the oil and gas industry. I was looking a bit beyond " we hardly kill anybody with the stuff we pump down there". If you could address what you think happened in Dimock, Pennsylvania; Pavillion, Wyoming; and Parker County, Texas, that would clarify that view.


In particular, what answers do you have for the Agricultural and civic water needs in water stressed regions like the Oglala aquifer?
What I presume is an agricultural advocacy group, Ceres.org doesn't think it's such a hot idea for them.

The Pavillion Field study was later found to be inaccurate.

To boot, the Pavillion Field was just weird. Fresh or crappy fresh water was as deep as a thousand feet. In between the fresh water zones were naturally occurring oil and gas zones. Normally, oil and gas is found thousands of feet beneath fresh water, which tends to be very shallow. I knew someone would pull the Pavillion Field paper out of their ass.

I read the paper. They didn't know how to interpret cement bond logs for one thing. It is what happens when a bunch of groundwater hydrologists who don't know how oil and gas trap write a paper. I'm a geologist, but I don' work hydrology. So I don't publish or work with fresh water. In the areas I work, like most areas, the groundwater is in the top 200 feet. The well itself is usually no shallower than 3000 feet.

Not all geologists are equal. The authors of that paper didn't have a clue. Like I have said, you gotta know how oil and gas trap.

99.99% of the time, your oil or gas target is super deep compared to the base fresh water.

In Oklahoma, the base fresh water has been mapped (using logs from oil and gas wells). You have to case and cement off the fresh water.

Rarely there will be a leaky cement job, but you know it and can either fix it or you will have to plug the well.

The U.S. has had millions of wells drilled since Drake's well. The technology is highly advanced. Casing off and protecting fresh water is tightly regulated. Groundwater protection is THE most important thing for regulators.

Oil companies don't want to be burdened by the Clean Water Act. It would slow drilling permits down to a crawl. I've had to jump through the hoops of drilling on federal land, and it is just a bunch of paper work. As I said, oil and gas are almost always found far deeper than fresh water (The Pavillion Field was an exception to this rule.

The respective states regulate fresh water protection, and do a good job of it. Like I have said, protecting fresh water isn't expensive. It is just an expense, like drilling cost. Protecting the shallow aquifers is easy and only a fraction of the total well cost. You don't dare not follow state requirements on your drilling permit. You can see the surface casing on the logs. Like I've said, casing it off and protecting it is a small fraction of the total well cost, and I've never seen anyone try to get around it. It is literally no big deal.

Around here, we have polluted ground water. Farmers have been fertilizing with nitrate fertilizers for decades and the nitrates have polluted the fresh water. Pregnant women can't drink that stuff without risking blue baby syndrome. Farmers are the ones who trash the aquifer, or shallow ones, anyway. They spray chemicals all over the land and it percolates into the water table.

In the same area are several hundred oil wells. Not one pollution case.

Like I said, it is easy to protect fresh water. Most oil and gas pollution cases are historic, and happened over 50 years ago. There are thousands of little 2 bopd wells that are operated by mom and pop businesses. Some of them are dishonest and dirty. The big companies spend the money to do things right.

So, if fracking trashes fresh water, why do companies routinely sample all surrounding water wells and drill monitoring wells prior to drilling?

So they can show that if the water is full of methane or other chemicals, it didn't come from them. This is now routine. As I said, you can blanket an area with pre-drilling monitoring wells for a pittance.

They do it to show that any methane in the groundwater is either natural or existed before they drilled. The Appalachian Basin is covered with little shallow gas wells drilled by mom and pop shops. Even with their lack of technology, methane in groundwater is natural in virtually every case.

In the NE U.S., over the Marcellus shale gas play, methane is commonly found in the groundwater. If you have ever seen Gasland, the guy who lit his faucet had naturally occurring methane. Even the director of the film was forced to admit it. He was unapologetic. In the real world, you deal with facts. That film was bogus. Only one pollution case was real, and that was from a surface spill. Gas doesn't come bubbling to the surface near fracked wells. You should be able to see that from the log I posted.

I can post a deep Woodford well, but they are super long and wouldn't fit.

Another thing. I'm a straight shooter. I don't bend the truth for anyone. I tell the truth, and I've been doing this for 30 years.

In particular, what answers do you have for the Agricultural and civic water needs in water stressed regions like the Oglala aquifer?

It is easy to address these things separately.

I've drilled tons of wells through the Ogallala. It is a fantastic aquifer, thick, porous, and icy clean water. I used to go jump into the tailwater pits during the summer to cool off. It is perfect water. Show me a case where the Ogallala was polluted by oil and gas drilling. You might find a couple, out of thousands of wells. Just because somebody is fracking on your farm doesn't mean that your groundwater is at risk. On the contrary. It is easy to protect.

The Ogallala recharges very slowly, and farmers have been depleting it for ages. Where you originally found the water table at 50 feet, it is now often found at 250 feet. Why? So they can grow corn in an arid area. At the same time we pay eastern farmers NOT to grow corn. Hell, a lot of the Kansas and Nebraska corn isn't even for food. It is for ethanol, a process that spews CO2. Oil companies are now hooking up to ethanol plants so that they can use the CO2 for tertiary recovery. A typical well drains only 10% or the oil in place. If you waterflood it you can double that. CO2 floods are fantastic, you can recover up to 80% of the oil in place.

Farmers are the ones who are chewing through the Ogallala. I'm not aware of any major fracking play even beneath the aquifer other than the Niobrara play. Everyone thought that the Niobrara would be a big play, but it turned out that the economic areas were pretty small. Around the Wattenburg Field and a patch in the Powder River basin.

The Wattenburg Field. That field is just NE of Denver and east of Boulder. That field was heated by the Colorado mineral belt, and is pretty isolated. It is also where the guy lit his faucet in Gasland. It is basically a big old gas field, although the Niobrara Chalk is more of an oil play. There is also a small part of the Powder River Basin where the Niobrara is economic.

Do some digging. There was one case where a jury found that an old gas well had polluted the water table. These things can happen, but are rare. Using isotopic analysis, other wells in the area which produced methane were from the water wells themselves. Not from the much deeper gas zones. It was biogenic gas, formed from microbes in the wells themselves.

If you gave a damn about the Ogallala, you would be upset at how fast that thing is being depleted. I drilled five wells a couple of years ago in SW Kansas. As far as the eye could see it was nothing but center pivot irrigation. Crops don't grow that far west other than wheat, which is a dryland crop. All of the corn being grown on top of the Ogallala is depleting it, and as I said, the recharge rate is incredibly slow. It is a non-renewable resource, and the farmers are using it up. Quickly in some areas. The farmers have been using it up far faster than it could recharge.

I've read articles about the deeper Dakota Sandstone aquifer. It isn't as clean, but might be suitable for irrigation. The problem is that the lower the water table gets, the more money farmers have to spend to pump it to the surface. The utility costs of many of those outfits is huge...yet corn grows just fine to the east where there is more rainfall. You can try to dryland farm corn in western Kansas and Nebraska, but you are at the mercy of the rains. Corn is very valuable compared to wheat, so they prefer to grow corn.

I remember looking out at all of that irrigation and not seeing a single weed. An utterly artificial landscape. Every inch of the area I was working was under center pivot irrigation. Every INCH. There wasn't habitat for a sparrow.

So if you want to go off on the Ogallala, you might consider who the culprits are: the farmers. The frack plays on it are small and isolated, and drilling has all but stopped.

The Pavillion Field study was later found to be inaccurate.

The 2011 DRAFT EPA Pavillion Field study was found to be flawed and EPA abandoned it before it was finalized. Dominic DiGulio, formerly with EPA, resigned from EPA and went to Stanford Univ. There he conducted a comprehensive study with Robert Jackson based on considerable data collected after 2011 and just published their study in the paper I posted ^^^ Additionally they were able to access EPA data via Freedom of Information Act (FOIA) that was included in their study.

To boot, the Pavillion Field was just weird. Fresh or crappy fresh water was as deep as a thousand feet. In between the fresh water zones were naturally occurring oil and gas zones.
This statement is accurate.

I knew someone would pull the Pavillion Field paper out of their ass.
Not sure whose ass you're referring to here. I posted a paper that was published in the Mar 2016 Environmental Science and Technology. Did you read this paper?

I read the paper. They didn't know how to interpret cement bond logs for one thing.
Not sure what paper you are referring to. Cement bond logs are not reliable indicators of well integrity, especially legacy well integrity. Only casing pressure testing can verify well annular seals, especially in legacy wells that can act as vertical conduits for frack fluids injected in a nearby frack well.

"Cement Evaluation Methods to Prove Isolation of Barriers in Oil and Gas Wells:
Should a Cement Bond Log (CBL) Be Run or Required in Every Well?

12 July 2012 George E. King, Apache Corporation

The purpose of this work is to establish whether a specific method or tool is effective in proving cement isolation of a zone, and if the method or tool should be required on the surface casing cement or other cement strings as a part of initial well construction (or, if not required, when it may provide useful information).

**Conclusion # 1. The only cement test method that can confirm zone-to-zone isolation is a pressure test.

The best way to ensure well integrity of the stimulated well is to conduct realtime pressure and flow monitoring during the stimulation. The best way to ensure the integrity of a nearby legacy well is to pressure test the casing.

In the areas I work, like most areas, the groundwater is in the top 200 feet. The well itself is usually no shallower than 3,000 feet.
Neither of these statements holds for California, where wells < 1,000 ft deep are fracked and protected groundwater can be 2 to 3,000 ft deep.

The respective states regulate fresh water protection, and do a good job of it.
Federal regulations protect groundwater < 10,000 ppm TDS. Unfortunately most states have not adequately characterized the extent of groundwater resources <10,000 ppm TDS. It is very difficult to protect a resource unless you know its extent. Also, it is difficult to design a groundwater monitoring network in advance of a well stimulation to protect groundwater. IMO the best way to protect groundwater is to conduct realtime pressure and flow monitoring during the well stimulation to ensure that the injected fluids and proppant went into the target zone. Some operators are adding short-lived radioactive tracers that can be used to ensure the frack fluids were contained within the reservoir target. If the realtime pressure testing identifies an unintended that might result in frack fluids extending beyond the target zone, then this information can be used to design a groundwater monitoring plan.

I'm sure you see that as an anomaly. It seems to some that disturbing those layers is pure idiocy.

Fresh water at depth is not weird. I paid for a 350 foot well once, and 600 feet in south central PA was pretty common. The ogallala aquifer is measured some places at 500ft.

To boot, those aren't the only issues. I understand North Dakota is still cleaning up a fracking waste spill with the Bakken shale and Missouri River from 2006. Some went directly into the ogallala aquifer.

Some of the stuff they pump in those wells is ( to use a technical term) icky.

Haha. Yeah let's have a discussion without talking about the disasters and what caused them.
We will talk about Pavilion because the industry got caught red handed doing the stuff they say doesn't happen with fracking.


The thing is, Pavillion isn't a one in a million chance you might want to dismiss. It's sloppy control over the hazards you don't want to talk about.
http://insideclimatenews.org/news/29032016/fracking-study-pavillion-wyoming-drinking-water-contamination-epa

The fault wasn't in the weird geology, it's that the oil industry didn't bother to check if it was there or didn't care. Pavilion was fracked because of the appeal of shallow gas. It's cheaper if you don't have to drill so far. oil company's fracked drinking water aquifers knowing they were close.
Published in Environmental Science & Technology, the Stanford study identified chemicals in Pavillion's water related to substances that companies reported using in local fracking operations and acid stimulation, an oil and gas production method. The researchers also found that energy companies frequently fracked at much shallower depths than previously thought, sometimes very close to drinking water wells. In addition, companies fracked into underground sources of drinking water, or USDWs, defined under federal law as aquifers that could supply a public water system. Fracking into USDWs is legal, but the oil and gas industry has long insisted that fracking occurs far deeper than where aquifers are located

Sounds like the company line that "we frack deep and water is shallow" is a myth.

And Pavilion didn't use proper disposal methods for the fracking fluids. Once they were out of the wells.

the other half of the Pavillion story was contamination above ground, from pits used to hold fluids or drilling mud. Prior to the recent fracking revolution, a number of these pits were used without any sort of lining to keep the contents from seeping into the ground. Petroleum-contaminated water from the gas wells went into those pits, as did diesel-fuel-laden drilling mud, so it comes as no surprise that contamination has been found around them. That’s especially true because of the way some of these gas wells were constructed. The researchers again dug through the available well documentation, noting that half of them lacked cement seals around the middle section of well pipe. This “intermediate casing” between the bottom and surface sections is now required in some states, but Wyoming is not one of them. In addition to that missing safeguard, at least a few wells have failed tests for leaks in the well pipe.

Put it all together and the researchers say it’s not hard to imagine that some fracking fluid leaked where it wasn’t supposed to.wqq

The funny part is when a geologist says dealing with the water isn't his job. Really? Why not?

If it takes "Fracking" then so be it...
OK as long is it is done in an environmentally responsible manner. I don't think fracking should be outlawed but I think it should be regulated. Unfortunately most State governments do not have the technical capability or resources to effectively regulate these operations. In some States, including California, the groundwater resources have not been adequately characterized.

IMO, hydraulic fracturing can be done safely with minimal impact to the environment and valuable surface and groundwater resources. Wastewater generated during drilling, hydraulic fracturing and production can be handled properly without negatively impacting the environment but, unfortunately, in practice, it doesn't always work out that way. It appears that primarily the smaller independents trying to cut costs by avoiding regulations are responsible for these violations. At this point, rig counts and hydraulic fracturing operations have declined significantly due to lower oil prices. Hydrofracturing in California has decreased considerably from 2014 & 2015. But let's not kid ourselves, the increase in domestic production, mainly from unconventional hydrofracturing, to offset foreign oil imports and keep pace with our nation's demand for fossil fuel resources comes at a heavy price.

Here's just one isolated example of what I'm talking about...

This photo taken on March 3, 2014, and provided by the North Dakota Health Department, shows bags full of radioactive oil filter socks, the nets that strain liquids during the oil production process, piled in an abandoned building in Noonan, North Dakota.

Reservoir fluids contain elevated levels of naturally occurring radioactivity, generally associated with natural U-238 and Th-232 decay series. These radioactive isotopes are concentrated in filters, know as filter sock, used to filter drilling and frack fluids. These radioactive filter socks ended up in an abandoned gas station.

Another impact has to do with the tremendous influx of oilfield workers into rural areas and the increase in crime, prostitution, drug and alcohol abuse, etc. Here's a video on how the Baaken boom has impacted rural North Dakota. The increase in jobs and money into these areas comes at a significant cost. Rockin' the Baaken...

Lorenzo, you've been at the Kool-Aid stand again.

Companies do NOT prefer to drill for gas at 1000 feet. Gas is a compressible substance, and an identical reservoir at 15,000 feet holds orders of magnitude more gas than a shallow well. I know. I once found a big shallow gas field. Our bottom hole pressure was less than 250 psia because of the shallow depth. We made it work by doing much of the work ourselves. It was simple enough for two geologists to do nigh everything, from running casing through installation of a large low pressure gathering system with strategic CDP's.

Shallow gas reservoirs are small. A big company can't make money at those depths unless the reservoir is very thick.

The original paper regarding the Pavillion Field was just awful. They couldn't read a damn bond log. The authors just had no oil and gas experience. I interpret at least 50 logging suites per day while mapping. I can interpret every vintage of log ever run in North America. That took a good 20 years of practice.

Here is a map of the Arkoma Basin showing only the horizontal Woodford shale gas wells. Do some reading and see if you can find an instance of groundwater contamination. The entire basin was drilled up without a single problem, or one that made the news.

Damage to the Ogallala aquifer, where it has happened, is tiny. Less than a hundred acres, and that was from a surface spill, not a casing integrity problem.

If you have a casing leak, you know it. The annulus will pressure up. If it is in the production tubing, it is easy to fix. The tubing isn't cemented in. However, on horizontals, you run at least one extra casing string (on the landing string), and often two extra strings compared to a vertical well.

How do you deal with a casing leak? Well, if you get one, you are in deep sh#t. Sometimes you can do a successful squeeze, but often you are forced to abandon the well and plug it with cement.

There is a guy at Cornell who just hates fracking. He publishes in some off the wall journal, and hasn't a clue regarding operations and well design. He used a gulf of mexico dataset and used it to compare the likelihood of casing leaks in the Marcellus. The GOM is a tough place to produce, because they often have H2S in their gas, and the oil is high sulfur. At bottom hole pressures and temperatures, it is highly corrosive.

Casing leaks tend to be geographic, and happen to old wells. Parts of western Kansas have the shallow Cedar Hills sandstone above the oil zones. It contains saltwater, but it is very corrosive. The solution is to run a DV tool in your casing string to cement it off. You know what a DV tool or Port Collar is, I assume. Anyway, if you don't do that, you will probably get a leak in your long string within a few years. Shale and drilling mud fall into the hole, and you know it right away. Up there, it is unlikely that you can save the well. You have to plug it.

Major County, Oklahoma has a Council Grove zone uphole that is corrosive. Not nearly as bad as the Cedar Hills, but bad enough for casing leaks to be common in that area. What do you do if you get a leak? You can roll the dice and try to fix it, but if it is an older stripper well, you just lost the well.

These are pumping oil wells in most cases, too. There is nothing wrong with the surface casing, and fluid level in the wellbore is usually less than 2000 feet from bottom.

Now explain to me how a horizontal fracked well, which has low permeability and hence low flowing pressure (typically well below 1000 psia of flowing pressure on the tubing string), is more likely to get gas contamination in the groundwater as opposed to a 20,000 foot Springer well with 15,000 psia of pressure at the wellhead? You can't. Low perm wells have low flowing pressure, and your perm doesn't get much lower than in a shale. Shale gas wells almost all have low FTP's. It is the only way you would be able to guess that a well is a horizontal fracked well from a look at the wellhead.

Horizontal wells are not more likely to have casing leaks as opposed to other gas wells, they are LESS likely, and if you get a leak, you see it on the annular pressure behind the production string. The surface casing is still there.

It is very, very, rare for a gas well to contaminate fresh water.

Here is a map of almost 2000 successful Woodford horizontal shale gas wells in the Arkoma Basin. Get on Google and try to find me systemic groundwater pollution. Hell, try to find a single case. You don't have to stop there. Go over the the Anadarko Basin CANA and SCOOP plays, and show me trashed groundwater over there. It is a couple of thousand more wells.

Unfortunately most State governments do not have the technical capability or resources to effectively regulate these operations.

Sorry, but this has put me in a sour mood. Do you even know who regulates drilling operations in Texas? It is the Railroad Commission. They have been looking at applications and enforcement since its inception. Their technical expertise is as good as it gets.

In Oklahoma, it is the Corporation Commission, Oil and Gas Division. I know geologists who work there, and I've been admitted as an expert witness as a geologist. The division regulates the SNOT out of the industry, both in house and in the field. They also have been around for at least 60 or 70 years, and look at EVERY line of a drilling application, a recompletion application, a plugging application, you name it. They witness every well plugging in the state. They also witness cementing of the surface casing, unless they can't get away. They can walk onto any location and shut it down for no reason.

The feds have never really regulated oil and gas activities. It is done by the states. The rules are strict but fair. Departure from any "normal" procedure takes a hearing, much like a court case. Field operations are overseen by a fleet of field inspectors who learned their jobs from...drum roll please...their own experience in the oil and gas industry.

The EPA has zero experience when it comes to regulating oil and gas activities. I've never heard of anyone drilling a well and having to deal with an EPA inspector. Perhaps because the closest office is in Dallas.

The EPA has been trying to get into regulation using the clean water act for decades. As long as the rules are proper, I see no problem. Their problem is that they would have to hire an entire division to oversee every drilling or plugging operation.

They just don't know how to do it. My wife is a high level manager at the state DEQ. She has a fleet of engineers and geologists working under her, but they work on other things, like RCRA, Superfund, landfills, you name it. Their geologists couldn't read a log unless they had by circumstance worked in the industry before. I doubt one in 20 could, and I can read a log as fast as I can flip it or scroll it on my computer.

They work very hard, but they aren't in the oil and gas regulation end of things. The states regulate the industry, and one thing is certain: the rules are fair and easy to follow. If you do anything wrong, the corp comm can shut you down in 60 seconds. These guys have worked on thousands of wells and know what they are doing.

Again, as I said above, most groundwater pollution happened prior to 1960. Back then, casing requirements were nigh non-existent. Now you have to submit your bond logs within 30 days. If you don't, they will shut you down.

Cement Bond Logs, or most cased hole logs, are not expensive to run. You WANT a good cement job, or as I've repeatedly said, you will lose the well. Modern wells rarely go bad. I know of a case where they burst the long string on a fracking operation in the Hardeman Basin. The casing isn't just there to keep the groundwater clean. It is there to isolate your producing zone from uphole saltwater zones, caving shale, etc. Casing integrity is vital to a healthy well. I've produced a few wells that had casing leaks when we bought them, but eventually we lost the wells. Now you can visit those spots and would never know that they were there. Anyway, when they blew their casing (and this was a very small outfit), they lost the well. Several million bucks down the drain. You know it, too. The annulus pressure spikes, and you shut down the frack. It is rare, but we talk business and something like that gets out.

There have been a few blowouts on Woodford wells. To get down to the Woodford you have to drill through an overpressured zone (in the Anadarko Basin...the Arkoma is all underpressured) and blew out. The rig burns down, you have to call the Hellfighter types in Houston, and within a couple of days they get control of the well.

Blowouts are really rare these days. In this area, you know when you get directly above the overpressured zone, and you stop and put in an intermediate casing string. Then you drill on with 16 pound per gallon thunderf*#k mud. If you didn't run that intermediate string, the hydrostatic pressure of your well would be so high that you run the risk of exceeding the failure envelope, losing circulation (sort of through an accidental frack, only with drilling mud), and losing the hole and the rig.

The shale doesn't blow out. It has super low flowing pressure until you case and frack the zone. Even then, low perm zones have low flowing pressure. I don't know how many ways to explain this.

In a way, I don't blame you guys for being so screwed up over this. There is so much baloney out there that even an intelligent person can't find the truth, which is pretty basic.

They have set up a recycling system in the Anadarko. You can clean the TDS's out of your flowback frack water and use it again and again. It isn't really that nasty to begin with. It is pretty much just fresh water with 3% KCL added to it to prevent swelling of any clays. You could use produced saltwater if you wanted to, but that stuff is heavy, and it would take forever to truck in enough for a frack.

The Shale fracks are pretty clean. I wonder why nobody bitches about diesel fracs with cross linked gel. Certain sandstones require those types of fracks.

In Oklahoma, the majority of wells need to be fracked. It is such a common practice, and has been going on without trouble for so long that it really surprised me when people began to attack fracks. I would have thought that they would be pissed over all of the wells. It takes a lot of wells closely spaced to drain a shale accumulation. The laterals are only 350 feet apart or so. So close that you can drill 6 wells from one pad, with each wellhead less than 30 feet from the others.

It is of vital importance that all cement jobs be done properly, just from an operations standpoint. The shale gas wells cost up to 18 million bucks to drill. A good surface casing job is a pittance. Only a few per cent of total well cost. Modern cement jobs are very different from the ones early in my career. Cement is a big word. There are a zillion types of cement, and modern thixotropic cementing rarely fails. It has never happened to me in my whole career. I've never seen a bad cement job. They can happen, just like you can get struck by lightning, but it is really rare.

I've NEVER seen a well with leaky surface casing. I'm sure that it has happened, but I've never seen it, nor has it happened to any of my friends. Ever.

Drilling shouldn't be allowed everywhere. I'm vehemently opposed to drilling in the Arctic Refuge, where I've spent 3 solo summers. Not because it will be a mess, but because it will industrialize the place, politely, but certainly.

I have no problem drilling on farms, though. I have no problem drilling in a city, either. There are producing wells within just a few miles of my house. They don't cause any problems. They are just dangerous if any high school kids climb the barbed wire and ride the pumping unit..a good way to lose your limbs.

What a pack of lies and deception. Base is obviously a paid shill for the fracking industry, spewing bullshit like its toxic waste pumped into our groundwater.
Of course you can't pump toxic waste and chemicals into the water table and expect it to stay in one place. NO F*#KING WAY. It migrates, common sense tells you that. Does not take a Rocket scientist to figure that one out.
And if there is one thing I learned in engineering school,, it's that even very minor hydraulic pressure moves very large things. It's the nature of hydraulic pressure and why you can jack your car up with one hand. Fracking does and will cause earthquakes.
Are we so f*#king stupid that we allow industry to poison our groundwater for a thousand years so some corporation can make a fast buck?
Jesus h Christ, unbelievable.

How much do you get paid for each of your bullshit posts Base? Let's hear it.

You obviously don't know me. I'm a very liberal democrat, although it is the liberals who have let their panties get in a bunch over fracking, and the idiotic tacts regarding the Keystone Pipeline. I pretty much despise conservatives, because they have bankrupted this country with irresponsible wars and tax cuts for the rich. They make me ill, and I don't see how they can honestly justify their behavior. The really super rich often make their money in stock and real estate speculation. Their income is mainly capital gains. That is why a billionaire pays far less taxes, by per cent, than a secretary. The capital gains rate is too low. They should do away with capital gains and tax everything as normal revenue. It will never happen. The rich control congress.

The governor of Oklahoma, as well as Brownback in Kansas, both managed to put our states in huge financial holes by handing out tax breaks like candy. Kansas is totally screwed up, and both governors managed to put us in the toilet during an oil boom. Especially in Oklahoma.

Did you know that most states tax the snot out of oil and gas? It is called the Gross Production Tax, and it is exactly that. It comes off the top, withheld by the purchasers. It is 7% in Oklahoma. That is a profit margin for many industries. Here is a list of taxes by state. Oddly, California doesn't have a gross production tax, but in the oil states, tax revenue is one of the main sources of government revenue. It brings in about 10 billion dollars a year, or did when prices were high:

http://www.ncsl.org/research/energy/oil-and-gas-severance-taxes.aspx

All you can do is respond with the ad hominem attack. Do you even know what that is? Obviously you don't realize that it makes you look like the village idiot. You can't out argue me, because the data is on my side. All you can do is call me names. Dealing with idiots like you just gets under my skin, and I apologize to the others on this thread. I shouldn't even respond to you, but it is important for people to know that I don't lie. I don't fib on this topic. I'm insulted that you would accuse me of it.

I am a petroleum geologist, with 30 years of experience in all sorts of reservoirs. I've found enough oil and gas to cover everyone here, along with their relatives and friends. Most geologists don't find a drop of oil, or a puff of gas. I've been finding it consistently for my entire career, often by finding subtle reservoirs that prior operators had drilled right through, and missed. I've evaluated at least a million logs by now. You don't even know what a log is.

The royalty I have in my very first well still brings in a couple of hundred bucks per month. I've found billions of cubic feet of gas, and an equivalent amount of oil. I have other interests, so I could have been more prolific, but I know how to find oil. Do you even know how oil traps? Do you understand a petroleum system? Do you understand capillary pressure? Lithology and basin modeling? Reservoir drive? I seriously doubt it. You are merely a name calling idiot.

I am talking to a bunch of meatheads here. I forgive most of you, because you haven't been formally trained. However when people spout bullsh#t, like this as#@&%e, well, it pisses me off. Sorry about that.

I LOSE money posting here. I normally post when my computer is thinking. It can take a few hours for it to grid some datasets, and I have to wait. Otherwise, this place is a huge waste of time. My rate is a lot, and I try to educate you people for free.

I do care about the truth. Any scientist has to be. In this mess, the average person has no clue as to what the truth is. As I said, it really isn't their fault. The media has done a poor job of explaining how fracking works, and there is an incredible amount of poor info out there. Even an intelligent and open person has trouble finding out the truth, because there is simply too much bad info out there. I've seen the New York Times get it wrong. So in a way, it isn't you guys' fault. I really wish that you could look over my shoulder for a couple of weeks. Take a field trip to some outcrops. Visit the core library.

FYI: I've never worked in the "fracking industry." I currently work high perm conventional zones. Vertical wells that we find using 3D seismic in old areas. I do consult on acquisitions and things like casing point elections, when to or not participate in a proposed well, that kind of thing. That often involves a horizontal play, but I lose zero sleep over it. The truth is, natural gas is the cleanest of the fossil fuels, and we should be using it more. The number of undrilled, yet proven locations, is huge. The big fracking companies didn't come close to fully developing before the price crash led to a drilling halt. Right now, everyone is getting laid off. I'm a consultant, so it doesn't affect me or my income so much, but things have slowed down. I had 9 prospects ready to shoot in SW Kansas when the crash happened. All of them are now on hold. They will get drilled, it will just have to wait until prices recover.

In the course of business, I've looked at hundreds of fracked shale gas wells. I understand their decline curves and recoverable reserves and rates. There are thousands of them here, but I don't need to look at every well. I own interests in 4 or 5 fracked Woodford wells. I make less than a thousand a month off of fracked wells.

I map oil and gas accumulations and predict where the next one will be. I've got a good record. Not too many dry holes, but you will drill dry or sub commercial wells. It is just part of exploration.

Shales are different. They cover huge areas. Not everywhere in a basin, but still a big area.

Being small, I find it easier to sell a prospect that costs 400 grand to drill as opposed to a play where it costs 10 million bucks to drill a well. So guys like me tend to play the shallower areas. This often precludes any chance of shale gas production beneath my shallower production. There are "fairways" in these shales where the temp/pressure history is just right. If it hasn't been buried deep enough, the shale is immature and won't produce. If you go too deep, then the shale is overcooked, and all you have is gilsonite, graphite, and the like. You follow these organic rich shales around essentially a certain depth range, because depth directly or indirectly is responsible for maturing those shales into the oil and gas windows. We call it the kitchen. We've been drilling right through the Woodford since the beginning of time, so there is plenty of well control. You don't have to worry about missing it. You do need to find the correct maturity level, and proper lithology. Most shales won't frack. The Caney overlies the Woodford and is also organic-rich. However, it is full of ductile clay and you can pump on it until the cows come home. It isn't brittle enough, and won't fracture. As I've said, you have to steer the horizontals through very specific intervals. It is pretty cool. There is a gamma ray scintillometer behind the bit, and it "talks" to you via pulses in the mud system while you are drilling. Those downhole tools cost over a million bucks. We got stuck and lost one once. It cost me a year's salary. Anyway, the gamma ray tool shows you lithology, and using it, you can stay in a 10 foot thick stratigraphic interval over a 10,000 foot long lateral. I've steered horizontals. You get no sleep and it is high stress. I can do it from anyplace with an internet connection. Hell, right now I am wearing dirty socks and looking at an area 200 miles away from where I am sitting. If I have the data, I can map Greenland in my underwear. It is all software driven.

So. People think fracking is bad. What about Hartshorne Sand wells? They are shallow (3000 ft) and the permeability is low enough that they need a frack. So does the Booch and other zones in the Arkoma, a gas basin. ALL of the zones need to be fracked, other than wells producing from the Cromwell, and most of them need a frack, too. What is wrong with that? They've been fracking wells in that basin for ages. No problems, or no major systemic ones. You are always going to have accidents. Right now you wouldn't believe how tight the rules are out on a drilling rig. They have to wear Nomex in the summer heat. Times have changed.

This has been going on for many decades. Since the forties. Well integrity has greatly improved since then, but I'm not aware of a single case of groundwater contamination in the Arkoma. Not a one, out of 50,000 wells.

Here is how groundwater gets screwed up:

You inject saltwater in a waterflood and within the area there is an old, improperly plugged old dry hole or plugged producer. In those cases, you CAN get cross well contamination. That improperly plugged well is a conduit to the surface. Modern plugging jobs are well done and not too expensive. You shoot off any production casing above the cement, and then go into the well, spotting cement plugs from the base to the surface. The entire surface casing is filled with cement, and in between the plugs you place heavy drilling mud.

Improperly plugged wells didn't even set any plugs in many cases. They dumped garbage down the well, cut off the casing below ground level, and walked away. You would never know that that well existed from just looking. You need to know where every well is. That is what I do. They just did things that way in the 30's and 40's, where most of the groundwater pollution has occurred. It is basically unheard of with modern wells.

We call those old wells "mud plugged." If you want to inject in the vicinity of that old well, the corporation commission requires you to re-enter that old well, clean out the junk, and properly plug it. It is a huge expense for the secondary recovery companies.

That's it. A frack job does not shatter the ground beneath your feet. It does not fracture outside of the target zone. What happens is stuff goes down one well, and comes up an old, improperly plugged well. This is a big deal if you run or want to start a waterflood operation. The Pavillion Field is an attempted example of cross well contamination.

I've never seen a frack go down one well and then shoot up through an unplugged nearby well, but in theory it could happen. That is not regulated. It is the only real way for a frack to contaminate groundwater.

I know of some terrific waterflood candidates that have a number of old, improperly plugged wells in them. Your injection permit will not be issued until you do go back in those old wells and properly plug them.

Most oil wells produce on pump. Some flow for a while, but they all end up on artificial lift. The hydrostatic pressure in that wellbore will never allow fluid to reach the surface, other than through the production tubing, where the pump is set. Most gas wells flow. Some make enough saltwater to require artificial lift, but that is a minority of gas wells. Gas is light. If you don't have any fluid in the well, it will flow.

Gas wells don't normally have pumps, as I just explained. They flow into the sales line. Therefore, gas wells are under pressure. The pressure is lower when producing. When shut in, the well will reach equilibrium, and you can tell how much gas is left in the reservoir through what is called a 4 point test, but really all you need to look at is the pressure gauges on the wellhead. So, yes, gas wells are under pressure at all times. You should be there when they open up a well to the atmosphere. Even a small gas well roars and shoots a 30 foot flame. We flare it. It is unsafe to just vent a large amount of methane.

The roar is incredible. It sounds like a jet. Just let it flow for a minute. You will release about 5 to 10 dollars of gas. Gas is cheap. It is undeniably the cleanest fossil fuel. It isn't as dense as oil, meaning that you can't fly airplanes very well using it, but we are swimming in it and it is dirt cheap right now.

I made far more money from my gas production back in the 90's than I do today. Gas used to be around 3 bucks per thousand cubic feet (mcf). Right now it is less than 2 bucks per mcf. It is a fantastic resource, and we have drilled only a fraction of the number of possible horizontal shale gas wells. With gas, we could cut our oil usage. While oil is a truly international market, gas is almost a wholly domestic one. You can't put gas in a bucket and carry it around. Yes, there is LNG, but it is expensive, and the LNG market is small.

Let's look at Iran. Iran is a mature area. That means that it has been fairly well drilled. They have found the big oil fields. Since exporting oil is their main source of income, it hurts when their citizens use the oil at cheap, subsidized prices.

Iran happens to sit on some of the biggest gas fields on the planet. Truly huge. They are just sitting there, stranded with no market. Iran has led the world in converting their vehicle fleet to natural gas instead of gasoline. This way they use their plentiful gas at home and are able to export more oil.

Now it is odd indeed, but Iran is ahead of the rest of the world here. We should be switching to natural gas as a transportation fuel, and people need to stop worrying about fracking. It is a red herring.

Wouldn't that be a good thing? To use a cleaner fuel? There is no Pavillion Field in Oklahoma. Does anyone here know about the oil seep in the Wind River Basin? Back in the 1800's, when mountain men and Indians roamed the plains, they knew about an oil spring there. It was a major seep. Later, when the area was drilled, the seep stopped flowing.

I can show you places that have live oil at 50 feet. I can show you gas at 300 feet. It isn't worth drilling, because the shallow depth has low pressure (and hence less gas). It is there, though. If you are sitting on a deep sedimentary basin, one that has all of the hydrocarbon ingredients required for accumulations, it is likely that you will also have surface seeps, or gas in the groundwater.

I guess I can name one of my clients, though. I spent a year working with their New Ventures wing. It was Chesapeake Energy, one of the top frackers and natural gas producers in the country. I was involved in non fracking project. Still, even though I was compartmentalized, because I was an outside consultant (although I had an office), I noticed how the company did things.

Whenever a new hire happened, you would get an email. I was surprised, because they were hiring in a groundwater group. I didn't know this, that Chesapeake has been, for years, sampling every water well in an area, and drilling their own water monitoring wells, just to verify that if there was gas in the groundwater, it wasn't them who caused it. I have never heard of another company regularly doing this, but apparently it was just part of the workflow in the company. They knew that they weren't causing groundwater contamination, so they drilled baseline wells to have proof. A landowner lawsuit can cost millions of dollars, and greatly tarnish a company's reputation, so CHK was doing this. God knows how much they spent in the Marcellus, but they had an entire group mapping the naturally occurring gas in the groundwater of the basin. A massive basin, with probably a million water wells. Yep. They were mapping that, just like the rest of us were mapping oil and gas accumulations.

Landowner lawsuits can be baloney. In some areas, they have always had gas in the groundwater, yet try to blame the big company when they show up. It is a cottage industry, like drug lawsuits. Attorneys troll for this stuff.

So Chesapeake set about proving groundwater quality pre and post drilling. An expensive decision, and not one that many of you have heard of. They weren't advertising that they were doing this. I wish that I could have spent a week in that division, just to see the cool stuff that they found out.

Why would they do that, if they were trashing the groundwater? How many smaller companies didn't go that far in pre-drilling sampling? I had never seen such a division. It must have cost a pretty penny. A geology group who found nothing commercial. Whose sole existence was due to bullshit lawsuits over gas in the groundwater in Pennsylvania.

Then you have the frack fluid. People act like it is poison. Well, it isn't. Do you want to know what is in frac fluid? It is freaking online:

https://fracfocus.org/

They now have totally green frac fluids. Nothing that could hurt anyone. They are now doing green completions. That is not venting any methane to the atmosphere during initial flow testing, prior to pipeline connection. Also, if any methane is released, it is flared. Methane is a potent greenhouse gas, and yes, most oil company execs think that global warming is a bunch of hooey, but in the science divisions, we all agreed with the climate science. Anyway, although Methane is a potent greenhouse gas, it has a limited lifespan in the atmosphere. It breaks down in a decade or so. Nothing permanent, but the companies reacted to complaints and accusations. It costs nothing to test a well down the sales line as opposed to venting or flaring, so all it required was a change in technique. It didn't cost any extra to prevent fugitive methane emissions during completions.

They have bent over backwards. There is no systemic problem with fracking. Pollution cases are rare and not that serious. Certainly not as dangerous as having Radon in your house because you live on granite.

You see, natural gas is commonly found in the groundwater, just as oil seeps are common. Not everywhere, but Pennsylvania does have a place called Burning Springs. A spring, long known, that you can set on fire.

That is how groundwater is contaminated. It is already there. There are other ways to get methane in your water well as well, unrelated to any oil and gas activities.

That guy who did Gasland did the world a huge disservice by stirring up hysteria where no reason existed. That entire film has been discredited, I believe. There was one real case of pollution, and it was a surface spill.

Here is a little snapshot of the Woodford play in SE Oklahoma. The green horizontals are Woodford wells. The yellow ones are Hartshorne wells, a shallow zone. They drilled a ton of shallow (3000 feet) coalbed methane wells in the Hartshorne coal. There is also a Hartshorne Sand, but you can drain that with verticals (it does require a big frack, though). These verticals go back to the 60's in this area. The red wells are Booch Sand gas wells. The Booch is a really shaley sandstone. Super fine grained. The pore throats are so small that the zone has just awful perm. You would have a lot of trouble getting oil out of it, but the Arkoma is a gas basin. You frack the Booch Sand. All verticals. Big fracks for verticals, though.

I can mine data throughout the mid-continent. I can show you any well in the state of Oklahoma, it's production decline, you name it. I pay about 20 grand a year in software and data licenses.

In a way, this is a silly argument. Although the price crashes have killed drilling, and many companies will go bankrupt, fracking has been steadily occurring. There is no law against it, except in New York, and the only thing standing in its way is the great expense of the wells. Some wells cost as much as 18 million bucks. As I have hopefully shown, out of that cost, groundwater protection costs nigh nothing. A good, deep, surface casing string doesn't cost much. Every well does it, vertical or horizontal.

I've done a lot of wellsite supervision, and the surface casing is just a part of the operation. Like paying the rig contractor. It is necessary, highly regulated by the states, and frankly inexpensive. Also, horizontals have at least one extra casing string. Often two. There has been no common groundwater contamination, and the number of fracked wells is in the hundreds of thousands now. Tens of thousands of those are horizontal stage frack operations.

If you want to see systemic groundwater contamination, look at filling stations. For decades they had leaky tanks, but the EPA cracked down on this via the Clean Water Act and forced their cleanup. Pulling tanks was a big industry in the 80's and 90's. Now, most of the contamination has been cleaned up, or at least been contained.

Again, regulation is carried out by the states, and in most of them, they have many decades of regulation. The regs are strict but fair. Nobody bitches about them. It is just the cost of doing business. The feds have never been involved in onshore regulation of the industry, and frankly, they don't have the know-how. The OCC and the Texas RRC are both huge agencies with lots of rules and many field inspectors, as well as in house scientists and engineers.

Again. The rules are strict but fair. The number one priority is always groundwater protection, and it isn't expensive to carry out properly.

Here is what I've been looking at. Horizontal Coalbed Methane and Shale Gas wells in the Arkoma Basin. Look at the wells. In this map there are 2250 wells. Over 1500 are horizontal fracked wells. No problem.

Now hop to it and find me a systemic problem in this dataset. Answer: One doesn't exist. Every well on this map, vertical or horizontal, was fracked. The sandstones all need a frack, as well as the much deeper shale gas wells.

Well integrity in the stimulated well and wells within close proximity to the target zone (e.g, within 2x the expected stimulation volume) and the vertical separation between the hydrofracture stimulation target zone and the protected groundwater are the main issues that I see that need to be addressed in regulatory oversight of hydrofracture operations. The other regulatory oversight issue, of course, is proper handling and disposal of subsurface fluids into pits, underground injection wells, etc.

FYI, here's a 2011 (updated in 2014) National Resource Defense Council (NRDC) report that summarizes over 35 incidents in several different states where hydraulic fracturing is suspected of contaminating drinking water. The key word here is "suspected" because it is difficult to prove unless a unique tracer was introduced with the frack fluid and that tracer is detected in the drinking water aquifer. There are multiple mechanisms by which this can occur that are directly related to the hydraulic fracturing or handling & disposal of subsurface fluids during drilling, well stimulation or production.

According to the ERCB report, misinterpreted information related to a collapsed tube (pictured below) caused “off-depth perforations” at the shallow level. Crew employees were meant to perforate the surrounding rock at 1486 metres.

Studly, I lose money wasting my time posting here. Who on Earth would pay me to lie? On Supertopo? And you had better not say any of this crap to my face.

If you had read my posts over on the science and religion thread, really the only thread I pay much attention to here, you would see that I am a rational and consistent science type.

16,000 wells and 35 pollution cases is a pretty good record in any industry, as long as spills or accidents are small and get cleaned up promptly. I don't want to tell anyone that it isn't an industrial type process. However, if you visit a gas field that has been fracked, you couldn't tell them from the unfracked wells. You would have to have a log.

The only clue would be low flowing pressure, and high shut-in pressure, a tell tale sign of a low perm reservoir.

Still, I often can't distinguish a horizontal shale gas well from a fracked sandstone well from the 70's. Not from the decline plot. All I can say is I see low perm, and I need annual 4 point tests to even do that.

You know, P/Z data.

Anyway, I don't make a penny trying to educate any of you guys. That is a stupid question.

Perfing the surface casing is just incompetence. That shouldn't have happened. I've seen oil and gas zones behind surface casing, and it is cemented over its whole length, but that isn't typical. If you've run a bond log over your surface casing, you can perforate it and produce, but it must be cemented to surface (they basically all are).

I found a big shallow gas field once. It was in an area that had been previously drilled for deeper oil, and they just missed the shallow zone, which was between 550 and 750 feet, which is super shallow, especially for gas. We would run 2 joints of 7 inch surface casing and then cement our long string of 4 1/2 to the surface. Then we would perf that. It took special permission to use that casing plan, but we had to show our bond logs over the string. We never had a problem. Not one, but in this area there was no fresh water. The wells drilled dry as a bone. An air rig looks like it is blowing smoke, but it is actually dry shale fragments. If there is water, it looks more like a fire hose.

We did 40 or so of those shallow wells, and by controlling costs, made a ton of money. We did it very cleanly, though. We were involved with all of the surface owners in the area, where the minerals weren't severed, and everyone was happy. It was a lot of fun.

They are depleted now. Barely producing at all.

And how long does it take for toxic waste to leach into the ground table in so many of your "successful" sites. 5 years. 10 years. 30 years, 100 years. nobody really knows, contrary to your hypothetical musings. It's the nature of the unseen. What I do know is that the toxic poison you have injected into the ground will be there leaching into ground water for a thousand years and it's irreparable and irreversible. Your industry and you and your associates are criminal to the people of the future and to children yet unborn, that's your legacy. You call it a success story without any idea of the repercussions down the road, and knowing that in so many of these sites if not eventually most of them, that fracked toxins will migrate under hydraulic pressure.
And buddy I will say it to your face anytime. Your threat doesn't scare me anymore them a turd on a sidewalk. You think you have a right to the destruction of our children's future, simply because big money encourages your activities now. But it's bullshit and it's evil and I will not stand down pal. Go frack yourself.

That is absolute horse sh#t.

The ad hominem attack is the refuge of the mentally incompetent, and Studly certainly qualifies. I recommend that he read Carl Sagan's The Demon Haunted World, about junk science. I assume that he can read books, but who knows? Most people don't.

I can understand it if people don't like seeing oil and gas wells dotting the landscape. Who likes it most is the landowners, if they haven't already sold the minerals. They get a royalty of 3/16 to 1/4 of all oil and gas produced, right off of the top. Lots of farmers are millionaires because they first leased their land for thousands per acre, and then began receiving monthly royalty checks, which can be huge, if it is a good well and you own most of the minerals.

I don't agree with drilling just anywhere. I'm vehemently against drilling on the coastal plain of ANWR. I have spent three summers up there alone hiking around. One year I hiked across it, re-supplied at an eskimo village on the Beaufort Sea coast, and hiked back. Alone. 10 weeks. I've even published against drilling there, which led to me losing one huge job. The geology of the place has also been overhyped. It won't give us another Prudhoe Bay:

http://search.proquest.com/openview/a3e555f6f11cbb99168dd3e8de0e557b/1?pq-origsite=gscholar

I could go on for days, posting real data. Unlike the poster above, I'm a scientist and tell the truth to the best of my knowledge. I have no axe to grind. Right now I'm drilling high perm prospects in SW Kansas, where you don't need to frack the producing zones. Their permeability is incredibly good already. I've never worked on a horizontally drilled mega fracked well, although I own some mineral interests where a company drilled them on me. I get some small checks from those wells. Not much.

I've done many verticals with much smaller fracks. We have never had a problem, and these weren't the clean slick water/sand fracks that we see in the shales. I've done CO2 foamed diesel, Nitrogen foam, cross linked gelled water, you name it. There are many types of fracks, but the ones involved in the shale plays are mainly just sand and fresh water. That is why this hysteria baffles me. I can understand not wanting to see the landscape covered with gas wells, but fracking? It never occurred to me that people would latch onto that, and I'm deadly serious.

The fracking companies disclosed the full list of chemicals used in fracks, or at least the shale fracks, several years ago. You can find the chemical disclosure list, along with a lot of accurate information about cementing and well design here:

https://fracfocus.org/

There is no reason to lie. Despite the hysteria in some places, fracking has been going on without halt in most sedimentary basins around the country. The only thing that has slowed it down has been oil and gas prices. Natural gas is nigh free, the price is so low. Drilling has almost totally stopped. The wells won't pay out at these prices. They found so much oil and gas that it crashed the market. Victims of their own success. We will see some of them go under soon. Most have already layed off huge numbers of employees. The wells will continue to produce, though, totally uninterrupted.

They now have green frack fluids. All you need is water and sand, and the additives are all non-toxic, but even with the older recipe, it was mainly just sand and water. Additives are a very small amount of the total fluid anyway, and are there to control viscosity (guar gum, slickening agent) and prevent swelling of any Smectite or Illite clays in the reservoir. For that, you use Pottassium Chloride. A salt. You could use plain old table salt if you desired, but fresh water can cause these clays to swell, and it will destroy your permeability. We've been using KCl water on reservoirs since the 40's to prevent swelling clays from slamming the perm shut on you and ruining a well.

I've already firmly stated that the zones that are fracked are deep and confined by thousands of feet of overlying impermeable, ductile shale. You can't frack just anything. It has to be brittle. Most shales are not brittle, but the Devonian/Mississippian, and Cretaceous organic rich shales are prospective if brittle enough. Some are. Some are not. In Oklahoma, we have the Caney Shale which is carbon rich in places. You can't frack it because it has too much clay. With the Woodford, you can. The brittle shales are more like ultra fine grained sandstones. They are rich in micro quartz grains. The Woodford sourced most of the oil and gas in the mid-continent. We used to drill right through it. You would get a gas show, but there was no way to produce something with such low permeability until horizontal technology came around.

When you steer the lateral, you must keep the wellbore in this brittle layer. If you get out of it, your frack stage will fail. The rock just won't accept the fluid no matter how long you pump on it. You steer the well by using instruments about 50 feet behind the bit. They transmit information to the surface while drilling by sending low frequency pulses through the mud system. It is pretty cool. A good steerer could hit a beach ball 12,000 feet deep and a mile away. If you want to know how you cause the bit to steer, I can explain that. I've steered horizontals. They weren't fracked, though.

Is this clear? When you drill a horizontal, you then cement a production casing string over the lateral portion. You then selectively perforate a few holes at regular intervals. Each cluster of perfs will be its own frack stage. When you frack it, you isolate that cluster of perfs and frack that stage. Then you come back a little and frack the next stage. It is equivalent to having a fracked vertical every hundred feet. A frack can have 50 stages. Each one is like its own well. That is the brilliance of the idea: You drill one well, but you get the equivalent of 30-50 vertical wells out of one wellbore. Not every stage will frack. Sometimes you steered outside of the brittle layer and that stage will fail. Failure is defined as not being able to displace the proper amount of sand, or proppant. That's it. That's how it works. There is nothing knew about slick water fracks. We have been doing that for almost 75 years. There is a TON of experience when it comes to fracks.

Nuclear weapons won't fracture that ductile rock capping your zone, be it a tite sandstone or a brittle shale. Yes, that has been tried. The DOE had the bright idea of looking for civil uses of nuclear weapons in Operation Plowshare back in the early 60's. They detonated 2 in western Colorado and 2 in NW New Mexico. The Russians tried it far more times, and in at least one case they were successful in breaching the surface. I'm not sure how deep it was, though.

Read about it. It is a hoot:

https://en.wikipedia.org/wiki/Operation_Plowshare

Anyway, one of the nukes was tried on a low permeability natural gas sand near Rifle, Colorado. They placed cement plugs above it, and no, they didn't blow out. So cementing has withstood nuclear weapons, yes. It didn't work. Fracturing slowly, using water and sand, worked much better. That basin is covered with gas wells. All fracked ages ago.

OK. I've wasted enough time on this thread. You guys should be able to figure it out on your own from here. I will leave you with this recent NYT op-ed:

I've been involved in environmental litigation for about 15 years and deal with clean ups all the time. The main culprits to ground water contamination are those that operate storage tanks in various industries. Dry cleaners are very frequent flyers. Probably the biggest threat to surface water is storm run off from agricultural and urbanized areas.

UPDATE:
Soooo, I haven't been against fracking. But now I read that some states are spraying the salty fracking wastewater onto roads to act as a de-icer.

Are we nuts? Base, are you familiar with any of this?

http://www.scientificamerican.com/article/road-de-icing-fluids-may-contain-unhealthy-chemicals/

"Road De-Icing Fluids May Contain Unhealthy Chemicals Some of the salty liquid comes from oil and gas wells, and regulations controlling its contents and use vary widely between states and localities"

"The tricky aspect to regulating produced brine, Howarth says, is that there are no federal specifications for the standards it should meet before it is spread on roads. "It's a state-based process, and that's what concerns me because some states have taken the posture that they will not regulate [the oil] industry," she notes. "If unregulated, then we may be putting petroleum products, diesel fuel, solvents, known carcinogens on our roads and increasing the risk of cancer and really serious health effects to people.""
