The Dash for Unconventional Gas

Today's Financial Times has a generally optimistic article about the vast quatities of unconventional natural gas tht are now apparently within reach around the world:
All across Europe big oil companies are scouring millions of acres of countryside and buying up rights to tap the natural gas trapped in prehistoric shale beds thousands of metres below its surface.

The shale gas rush has made its way over from the US, where breakthroughs in technology have allowed companies to extract gas from reservoirs previously seen as untouchable.

The newly accessible US shale deposits are so big that executives now believe the country has enough gas to last it for a century. This extra supply and the US’s new found self-sufficiency has created a worldwide gas glut that has driven down prices.

It is a remarkable turnround. Just three years ago, most US energy executives were working out how the US could import enough gas from places as far away as Nigeria, Russia and Qatar, while competing with the demands from China and other energy-hungry developing countries.

Now the world’s biggest, richest and most sophisticated energy companies believe that they may be able to repeat the American shale gas revolution in Europe, potentially undermining the power of Russia, the region’s biggest gas supplier.

Not all are convinced. Over the weekend, John Dizard's FT column took a highly skeptical look at the prospects for abundant and cheap natural gas, and is worth excerpting at length:

I try not to get into arguments over other people's religious convictions. Even if you win your point, you make an enemy. That's been a conventional understanding since the Thirty Years War. Sometimes, though, you have to clear your throat and carefully offer a heretical thought, if lives or large amounts of property are at risk.

For example, I think it might not be a bad idea to examine the faith-based assumption that the US has a virtually unlimited supply of natural gas from shale formations that can be extracted at a low price for the indefinite future. Perhaps the few people who think shale gas will be produced at a higher cost, and more slowly, than generally believed should be heard out, rather than be executed or sentenced to work in the salt mines. If you disagree, I will quickly withdraw that comment.

The shale gas religion crosses the usual political boundaries. The environmentalist wing believes that shale gas can displace dirty, coal-fired generation. Liberals believe it will help power the clean energy policy. National security conservatives believe shale gas can end dependence on Middle Eastern or Venezuelan oil. Economic conservatives believe it can close the current account deficit, and drive an economic recovery, at least until even more nuclear power can come on line.

There are environmentalists, rural landowners and health advocates who worry that shale drilling could contaminate water supplies. Most of them, though, want to have more careful regulation, rather than prohibition, of shale gas exploitation.

I was prompted to comment on shale gas again after watching a well known, highly emotional American television stock market commentator suggest that shale gas will be so abundant that facilities for importing natural gas could be converted to export the stuff. This when the present low US price for natural gas is about 10 times the economic value of gas stranded in huge Middle Eastern deposits.
What is the basis for Dizard's skepticism?
Policy should be based on material reality, which is that maintaining, let alone increasing, US use of natural gas will require a very substantial increase in prices over the present spot and futures levels. On that point, the shale gas industry people and I are in agreement. One set of data points might turn out to be revealing. Look up the "balancing item" in the "natural gas navigator" on the US Energy Information Administration's website. This is how the difference between reported gas storage and the net of production and consumption is explained. For the last report, in December, the "item", or unexplained error, is about 100bn cu ft. That is a whole bunch of gas, as they say out there.

The "item" has been increasing steadily from the middle of last year. So production is likely lower, or consumption much higher, than the EIA has been able to count. Given that production is calculated from a sample of producers that is probably overweighted to large companies with access to capital markets, it is probably the case that production is lower than Washington, or most of Wall Street, thinks. Smaller gas producers, who are probably under-sampled, will have had their access to debt or equity proportionately much more restricted than was the case in the boom years.

If that analysis is correct, the US will run short of low priced gas sooner rather than later.

Cheap and abundant natural gas as far as the eye can see? Maybe not.

The capital will come from the oil majors as they snap up successful independents as Exxon- Mobil and BP have done.

Roger Pielke, Jr. said...

From John by email:

"Time frame is a key point. However even if there is only 1/2 the gas expected, that still gives much >50 years supply. And on a btu basis, gas is far cheaper than oil and would still be cheaper at twice the price. As has been noted on this site, there are no renewable options which could be up and running (let alone at a reasonable cost) to provide serious power quickly. The technology to run cars or power stations wuth nat gas is already here (though no doubt can get better, like any technology); so nat gas looks very attractive to reduce oil dependence and if one believes the CO2 AWG story then nat gas also looks good to substitute for some coal use."

The general rule of thumb worth applying is TANSTAAFL.
A rule of engineering comes to mind as well:
Faster, Better Cheaper: Pick any two.
The interesting thing to watch will be when the major oil companies prove, either way if the huge bet they are making on shale bed gas is more true, or more false.
My bet is it will be somewhere in between.

Craig said...

I would imagine Europe has learned a lesson being dependent on Russia for natural gas.

MIKE MCHENRY said...

Natural gas can also be converted to gasoline or diesel to fuel the existing fleet of vehicles some 250M in the USA. This is well established technology.

Luke Lea said...

Off topic, but I wanted to get this quote on the record:

"In its model simulations, the IPCC suggests that – because of higher temperatures – the world GDP in the year 2100 will be 2.9% lower than without any warming. I repeat, only 2.9% if we do nothing and let the warming – predicted by the IPCC – continue. The same models suggest that the GDP per capita in the developed countries will be eight times higher than now and in the developing countries about five times higher than that of the developed world today.

These figures are not mine, these are the figures of the leading exponents of the global warming doctrine. The question must be therefore raised: should we drastically limit CO2 emissions today by 20, 30, 50, or 80% and, thereby, abandon our way of life for the sake of such a small effect considering that the future generations will be far better off than we are today? My answer is that 2.9% of the future GDP is a minor loss." Vaclav Havel in recent speech.

Maybe Roger can address this issue in the future?

Peter said...

Here's a good place to learn some of the details about what shale gas is, where it is found and how it is produced. It is not a myth, as is man-caused global warming, (in my humble opinion).

Why not post on Tol's analysis IPCC economic forecast's? The blog just before this one from Roger.

DeWitt said...

A number of the IPCC SRES scenarios assume that there are vast quantities of methane out there somewhere.

markbahner said...

"Cheap and abundant natural gas as far as the eye can see? Maybe not."

"Cheap and abundant." "Maybe. Maybe not." That certainly covers all the possibilities. ;-)

Seriously, it might be a bit more scientific to actually look at studies that have been done on the subject of natural gas supply. I recommend: "MIT Energy Initiative: Study of the Future of Natural Gas."

My prediction: The U.S. annual well-head price of natural gas will not exceed $4 per thousand cubic feet for any 3-year period over the next 30+ years.

Natural gas will remain the heating fuel of choice for a very long time.

We still have 8 million homes in the US that use oil heat, which hasn't been price competitive in quite a long time.

We also still have oil fired electricity plants(down to less then 1% of total generation).

As we already have a quite substantial 'locked in' market for natural gas, it's quite understandable why companies would invest in new supply technologies.

The difficult question to answer is whether the future costs of supply will be stable enough to invest in additional demand technology.

Profane said...

"It is true that at best we see dimly into the future, but those who acknowledge their duty to posterity will feel impelled to use their foresight upon what facts and guiding principles we do possess. . .It is shown that the constant tendency of discovery is to render coal a more and more efficient agent, while there is no probability that when our coal is used up any more powerful substitute will be forthcoming. . .it will appear that there is no reasonable prospect of any relief from the future engine of industry. We must lose that which constitutes our peculiar energy." - William Stanley Jevons, The Coal Question (1865)

Every prediction of the type and quantity of future energy use for the past 145 years, even those coming from the very best minds, have been hopelessly flawed. We should not expect the predictions from three years ago or those from today to be any different.

This is no argument for complacency - the great, painful, unanswerable question is where we will be several hundred years from now, reverting back to wood from fossil fuels, or swimming in energy from technology as yet unknown?

jae said...

I would certainly rather place my faith in CH4, rather than "alternative energy." Speaking of which, the Administration is playing Chicago-style politics on this issue, also:

bernie said...

I have one of those 8 million homes. My town in Eastern Massachusetts is only partly served by natural gas. The town is spread out and has a relatively low density so putting in the infrastructure may offer too low an ROI for National Grid.

Sharon F. said...

OK Pete, I admit, I am not knowledgeable about all the natural gas terminology.. I found this on your website:
"Natural gas is a gaseous fossil fuel consisting primarily of methane but including significant quantities of ethane, propane, butane, and pentane—heavier hydrocarbons removed prior to use as a consumer fuel —as well as carbon dioxide, nitrogen, helium and hydrogen sulfide.[1] It is found in oil fields (associated) either dissolved or isolated in natural gas fields (non-associated), and in coal beds (as coalbed methane). "

Is the shale the same as a non associated natural gas field? coal is not shale, right? How do these all interrelate?

ljohnson said...

Sharon: yes, gas in a shale is probably non-associated. The "associated" phrase means its associated with oil production. Most crude has gas dissolved in it.

Coal is not shale, though some shales have a high carbon content.

ljohnson said...

It should be noted that US PROVEN gas reserves are at the highest level in US history.

This is after over 100 years of production.

There are more things coming down the pike, too, with regards to natural gas.

- Gas hydrates have been successfully produced in the Mackenzie Delta, in Canada's arctic. This will unlock a huge source of gas.

- conventional gas reserves in the arctic, Alaska and Canada, is probably greater than conventional reserves in the south. All it needs is a pipeline.

- There are many more shale gas provinces that can be looked at. Across Canada alone, there are 1/2 dozen shales that may have tremendous resources, from Quebec to BC.

- coal bed methane is another proven source of gas.

- I am aware of one project, where water is disassociated in the presence of heavy oil, and the H2 and O are recombined with the crude, to reduce the viscosity. The same chemistry could be used on coal, to produce CH4 and CO2. The CO2 would be removed, and you are left with gas. As the US has the world's largest coal reserves, it would open a lot of deep, unmineable coal to extraction.

ljohnson said...

Bottom line? With relatively small advances in technology, or slightly higher prices, there is probably 100 to 200 years of gas available in North America.

"It should be noted that US PROVEN gas reserves are at the highest level in US history."

I'll quote USGS
http://pubs.usgs.gov/of/2008/1202/
"Coal reserves are the portion of the recoverable coal that can be mined, processed, and marketed at a profit at the time of the economic evaluation."

I'll quote this article as well
http://www.icis.com/Articles/2008/07/30/9144315/shale-gas-can-meet-us-needs-for-100-years-study.html

"McClendon conceded, however, that despite availability of shale gas resources, anticipated US gas demand growth would likely keep gas prices in the range of $9-11/m Btu. The more complex and costly drilling and fracturing techniques required for shale gas development became uneconomical at around $8/m Btu and lower, he said."

Coal at $100/ton works out to be $4/million Btu's, Oil at $80/barrel works out to be $12/million BTU's.

Nuclear is cost competitive at about $5/million BTU's.

CNY Roger said...

The development of hydro fracking the shale formation to get this natural gas is on the front burner in Upstate New York at this time. The loudest voices are crying that it will destroy watersheds because of the large amounts of water involved in the process. Unfortunately those loud voices are crying for bans more than stringent regulations on the development so it will be interesting to see how this plays out.

One final point. I am an air quality meteorologist and once had the opportunity to ask one of the leading experts how we could ever solve the ozone problem. He said he thought that there was only one way - convert automobiles and trucks to compressed natural gas. That would reduce the VOC emissions but not the NOx emissions and that would be very effective in reducing ozone.

jae said...

CNY Roger:

Well, I think your "expert" is providing you with more environmental Orwellian nonsense, for most of the USA, at least. The controlling factor for ozone in all areas where there is lush vegetation (most of USA) is NOx, since the plants provide copious quantities of VOCs. Your source is probably a bona-fide Sierra Club member but not a chemist. I would like to know just who this "expert" is?

CNY Roger said...

JAE,
The expert was the president of one of the leading air quality modeling consulting firms in the country. While I will admit that vegetation provides quite a bit of VOC, the Olympic experiment where the locals were asked not to drive during the Olympic games in Los Angeles supports my contention that mobile sources are a driving factor. During the games the ozone levels went down substantially and went back up as soon as driving returned to normal. I believe the same effect was noted to a lesser degree in Atlanta.

jae said...

Thinking some more, my last comment was probably too harsh. In areas like LA and Denver NOx is the culprit. However, in forested areas, especially softwood forests, the trees produce so many VOCs that smog and ozone concentrations are limited by NOx.

Sharon F. said...

All- I just wanted to say that spending time thinking about the pros and cons of different energy sources, and figuring out the facts about them, seems extraordinarily useful; perhaps the same effort that the US puts into supporting IPCC could be redirected into having a FACA or bipartisan committee with all the relevant industries (and others) represented, to hash out the economics and environmental costs and benefits of different energy strategies..

MIKE MCHENRY said...

The size of the existing fleet of vehicles running on gasoline and minor amount of diesel is 250m. At current scrappage rates it would take 20years to replace it NG cars. It would be better to convert it to liquid. After isomerization the fuel would be the ideal gasoline with high H to C ratio and no PCA or heavy ends. These qualities would mean low exhaust VOC's and lower CO2 emissions. The unisomerize material makes the perfect diesel. Yes building gas to liquid plants is expensive, but consider the cost and complexity of building a pressurized NG distribution network.

America’s reliance on foreign countries for its energy will grow by 19 percent over the next 20 years, accelerating the transfer of U.S. wealth to members of OPEC by more than $600 billion. Bottomline: America needs it all!

24, Sharon F: You might be interested in the "Master Resource" site. Lots of very thoughtful analyses on energy subjects:

markbahner said...

"All- I just wanted to say that spending time thinking about the pros and cons of different energy sources, and figuring out the facts about them, seems extraordinarily useful..."

Indeed! I've written that hydrogen-boron fusion is the "ultimate" energy source:

http://markbahner.typepad.com/random_thoughts/2007/07/six-reasons-why.html

But unfortunately, it seems to have the minor problem that it's presently technically infeasible.

It's not *too* much of a step down on the "ideal energy" ladder to LFTRs (liquid fluoride thorium reactors). They are potentially much better than uranium fission reactors.

As Bill Gates pointed out, if there is really serious interest in lowering global emissions by 80% in the next 50 years, essentially no burning of fossil fuels for electrical generation or transportation are possible.

But natural gas that co-generates electricity and heat is pretty neat. I'd love to have a fuel cell in my crawl space that runs on natural gas, and uses jacket cooling water for hot water and/or cooling air for space heating. It's a significant problem in the U.S. that virtually none of our electricity is produced in a manner that the waste heat is used for useful purposes.

When Abraham Darby developed a method of producing high-grade pig iron using coke rather than charcoal, the result was Faster, Better,Cheaper and higher Volume.
