Progressive Commentary Hour with guests Kurt Cobb and Nate Hagens

In lieu of my regular weekly piece, I'm posting a link to a radio interview I did last week for the Progressive Commentary Hour as I take a brief hiatus. I was privileged to be on with Nate Hagens, former editor of The Oil Drum. We focused on the effect of peak (affordable) resources and climate change on the economy and society. I was pleased that host Gary Null had such a deep understanding and appreciation of the issues we discussed. You can find streaming and downloadable versions of the interview on the Progressive Radio Network site by clicking here and then scrolling to the bottom of the page.

Remembering where we live: Physics vs. biology

It is awe-inspiring to view images of galaxies and nebulas brought to us by high-powered, space-based telescopes. And, it is even more amazing to see depictions of such phenomena as if we, the viewers, are suspended in space a long, long way from Earth. In fact, in modern science fiction movies and television shows we are regularly treated to adventures that take place wholly outside of our solar system and even outside our own galaxy.

Artist's Rendering of The Milky Way

But there arises an obvious question when one looks at, say, an artist's rendering of the Milky Way with our place in it highlighted: Who is seeing the Sun, the solar system or the Earth from that vantage point? The answer, of course, is no one. No human has ever seen the Sun, the solar system, or the Earth from that distance. And yet, we can conjure such a point of view and imagine through special visual effects that we might someday actually see such sights with our own eyes. In fact, some people claim that it is only a matter of time before we do.

This is the distance the mind can travel using physics. Physics is "the science that deals with matter, energy, motion, and force" according the dictionary. It is the world of "res extensa," literally, "extended things." It presumably operates without respect to humans. If we humans weren't alive, physical laws would still hold in the universe; and, the world of objects, of "res extensa," would still exist. Physics offers a bodiless, infinite view of where we live. According to physics we live in the universe.

The shareable economy: Don't let the perfect be the enemy of the good

Last fall at the Shareable Cities Summit in Portland a panelist from Getaround, the car sharing service, made the astounding statement that car sharing had the potential to reduce the number of cars on the road by an order of magnitude--for the math-impaired that means 90 percent.

What makes this seemingly fantastical development possible is the fact the cars sit parked 95 percent of the time according to Donald Shoup, a UCLA professor of urban planning who has made a specialty of researching parking. (This fact has had a huge impact on the urban landscape. But that's a subject for another time.)

The received wisdom is that we are heading toward 2 billion vehicles on the road in the next 20 years, a doubling of today's 1 billion. This is put down primarily to auto demand in India and China. I've doubted this wisdom from the start because of obvious constraints on the liquid fuel supply. But virtually no one in policymaking circles believes that vehicle numbers are headed downward, let alone dramatically downward.

Is adaptation to climate change really feasible?

The climate change denial lobby likes to use a variant of the dog bite defense. Perhaps you'll recall the joke about the owner of a dog that bit a passerby. Defending himself in court, the owner says: "My dog doesn't bite. It wasn't my dog. And furthermore, I don't have a dog."

In similar fashion the climate denial lobby tells us: "Climate change is actually good for us. If it does cause problems, they won't be that bad and we should just adapt. And furthermore, there is no climate change."

The final argument has been increasingly difficult for the climate denial lobby to maintain, and many there have given up on it. And, the denialists have pretty much given up on the idea that climate change is good for us. So, they're down to arguing that it won't be that bad and we should just adapt.

In recent months this argument--which the denialists thought might only be tested far into the future--is taking a thumping. It's taking a thumping because climate change is moving so fast and its consequences becoming so devastating that it's hard to see how we are going to adapt to it easily and cheaply or, in some cases, even at all.

Is "the environment" now obsolete?

For millennia the presence of humans on planet Earth hardly made a dent in its ecosystems. Humans were at the mercy of their environment as much as any other creature. But with the advent of agriculture, humans began to influence the planet in major ways. Some scientists posit that the clearing of large swaths of land for planting over the past 10,000 years released enough carbon into the atmosphere to delay the next ice age.

Of course, in the past two centuries the pace of those carbon releases has grown exponentially with the industrial revolution through the burning of fossil fuels. These emissions now threaten to flip the planet into a warm state far beyond anything experienced by humans in their relatively brief time on Earth. The question we must now face is whether humans still live in "the environment" or whether they now are "the environment" by virtue of their actions.

The distinction mattered little as long as we didn't live in what economist Herman Daly calls "a full world." The introduction to his piece "Economics in a Full World" which appeared in Scientific American in 2005 states: "The global economy is now so large that society can no longer safely pretend it operates within a limitless ecosystem."

Living in a world we can't understand

What is not intelligible to me is not necessarily unintelligent.

                         --Friedrich Nietzsche

As we know, there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say, we know there are some things we do not know. But there are also unknown unknowns, the ones we don't know we don't know.

                         --Donald Rumsfeld, Former U.S. Secretary of Defense

We live in an age of enlightenment, in the belief that the entire universe is open to our inspection and more than this, that it is theoretically all intelligible to us. If we just apply enough science and enough rationality, nature will reveal all its secrets to us in ordered sets of data that we can then use to control the entire world around us.

That we can wrest a comfortable life from the Earth is, however, nothing special. Plants and animals do this without resorting to colleges, symposia or research laboratories. And, humans used to do it without these things as well. Ancient Greeks--if they survived childhood diseases, war and the occasional plague--regularly managed to live into their 60s and 70s among balmy Mediterranean breezes. It's not that there hasn't been any progress; it's just that we may not have made as much progress as we think.

Wonders yet to come: A sound basis for energy policy?

Last week when I laid out seven misconceptions about energy shared by the public and policymakers, the pushback I received had little to do with the actual data I used to demonstrate my point. This is probably because the data are from official public sources and available to anyone with an Internet connection to inspect and verify. Most of the pushback bore the sentiment, "Well, you are right about the data. But, just you wait. There are big things that are going to happen in the future with (fill in your favorite fossil fuel) because of (fill in your favorite technology and/or name of supposedly large fossil fuel deposit)."

This is what I refer to as the "wonders-yet-to-come argument." It's an argument that ought to be familiar (and tiresome) to most everyone. It's been used frequently since the oil price hit a long-term low of $10.72 a barrel in December 1998. Even as prices rose ten-fold and supplies advanced only at a snail's pace from 2005 onward, we were treated to frequent pronouncements about how the wonders of technology would deliver cheap, abundant oil soon. Though technology has failed to provide cheap oil, the wonders-yet-to-come argument is still being used to great effect on unsuspecting minds.

We've actually had a good test of this argument since 1998 in the oil markets. Around that time it was deepwater drilling that was going to keep the world awash in cheap oil for decades to come. Check out how many times both the International Energy Outlook 2000 produced by the U.S. Energy Information Administration (EIA) and the World Energy Outlook 2000 produced by the International Energy Agency (IEA) mentioned the key role deepwater oil development was expected to play in raising world production and keeping prices low.

7 things everyone knows about energy that just ain't so (2013 Edition)

Mark Twain once said, "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so." And, there are many, many things that the public and policymakers know for sure about energy that just ain't so.

That list is very long indeed and getting longer as the fossil fuel industry (which has little interest in intellectual honesty) continues its skillful manipulation of a gullible and sometimes careless media.

Below I've listed seven whoppers that it would be charitable to call misleading. Longtime readers will recognize that I've addressed them before in various pieces. But I thought that it would be useful to review the worst of the worst of 2013 as the year ends.

Here are seven things everyone knows about energy that just ain't so:

1. Worldwide oil production has been growing by leaps and bounds in the last several years. Oil companies (with governments following suit) have cleverly redefined oil to include something called natural gas plant liquids (NGPLs) that you might surmise actually come from natural gas wells. These include propane, butane, ethane, and pentanes. The new definition also includes biofuels such as ethanol and biodiesel.

This mishmash is sometimes referred to as "total liquids," but more often "total oil supply." This redefinition, however, depends on something that just ain't so, namely, that NGPLs and biofuels are 100 percent interchangeable with oil. There is some interchangeability, but the volume is relatively small. NGPLs make up just 10 percent of total liquids. I've seen investment research that asserts that probably less than one-fifth of that (equivalent to about 2 percent of total liquids) can be directly substituted for oil, primarily in petrochemical refineries. That portion could grow, but only with extensive and costly retooling of the refinery industry, a move that seems risky with U.S. natural gas production stalled (see below).

Now, the central problem with including NGPLs as part of the oil supply remains that they have only a very limited ability to be used as transportation fuel which is the main driver for oil consumption.

Moreover, the energy content of NGPLs is around 65 percent of oil per unit of volume. Ethanol has about 66 percent of oil's energy, and biodiesel has slightly more than crude oil, but somewhat less than the diesel it is meant to replace. We must also consider all the energy including oil that goes into growing, harvesting, transporting and processing the crops that are feedstocks for biofuel refineries. Some studies show that more energy goes into making ethanol than ethanol produces when burned in an engine.

Despite these well-known facts, the industry and government continue to count NGPLs and biofuels in barrels right alongside oil as if they were all equivalent.

Ethanol and biodiesel do directly substitute for some motor fuels. But there are upper limits on what we can produce and use. We are near those limits with ethanol unless engines change to tolerate higher concentrations of ethanol. Moreover, neither ethanol nor biodiesel can be used for the wide variety of purposes that crude oil can.

It turns out that 2005 was an inflection point after which supply growth for both total liquids and oil proper slowed considerably. With all this in mind, let's look at the actual numbers which come from the U.S. Energy Information Administration (EIA).

Total Liquids:

Growth from 1998 to 2005: 11.7 percent

Growth from 2005 to 2012: 5.7 percent

Oil Proper (Crude Oil Plus Lease Condensate):

Growth from 1998 to 2005: 9.9 percent

Growth from 2005 to 2012: 2.7 percent

You can see that the real oil supply (crude oil plus lease condensate) has been growing at just over one-quarter the pace it did in the previous seven years--even with record prices, record investment and the wide deployment of new extraction technologies. Slowing growth coupled with skyrocketing demand in places such as China and India has put a lot of upward pressure on oil prices. It's one reason oil prices remain near record highs based on the average daily price of Brent Crude, the world benchmark.

In 2011 the average daily Brent Crude price was a record $111.26—which was followed by another record in 2012 of $111.63. The price in 2013 through December 26 has averaged $108.52.

2. U.S. natural gas production continues to grow by leaps and bounds. This claim is even more misleading than the first one. It's true that natural gas production has grown in the United States in recent years due to the exploitation of gas trapped in deep shale deposits, deposits that new technology called hydraulic fracturing is now making accessible.

But, it turns out that the rate of production of these wells declines rapidly, and the numbers suggest that raising the overall U.S. rate of production is going to be very difficult and expensive from here on out. In fact, since January 2012, monthly U.S. marketed natural gas volumes have been nearly flat despite a more than doubling of natural gas prices from their April 2012 lows. The average monthly volume in 2012 was 2.11 trillion cubic feet (tcf). For 2013 the data are only available through September, but the average through that month was 2.12 tcf. It's doubtful that the average will change that much when the final three months of the year are included.

The easy shale gas has been extracted. Now comes the hard stuff. We may already be on the shale gas treadmill.

3. There is enough natural gas under the United States to last the country for 100 years. This claim requires that you first do bad math on the numbers even the perpetrators of this falsehood provide. The number turns out to be 90 years using their figures and 2010 U.S. natural gas consumption (while assuming, improbably so, no growth in U.S. natural gas use for the next 90 years).

But even that number vastly overstates what we are likely to get out of the ground for it includes estimates of probable, possible and speculative technically recoverable resources. Now, just because something is judged to be technically recoverable does not mean it will be economically recoverable. And, if it is further labelled possible or speculative, it seems foolish to base our public policy on such resources as if they were proven to exist and were ready to extract.

Shale gas expert Art Berman suggests we focus on the probable resources category and assume generously that 50 percent of those resources will actually get turned into reserves. (Keep in mind that no resource is ever exploited to 100 percent and usually only to a fraction of that. Also, resources are what are thought to be in the ground based on sketchy evidence, while reserves are what the drill bit proves are actually there and, more importantly, amenable to extraction.) Based on these assumptions, the United States has about 550 tcf feet of probable and proven reserves which means that the country has a likely supply of about 23 years (again, assuming, improbably so, no increase in the rate of consumption during the entire period).

Since Berman made those calculations, some of the probable resources have moved into the reserves category. But, the outlook has not really changed because this was expected.

4. The United States is about to become the world's largest oil producer. This claim depends on the same sleight-of-hand being used to inflate worldwide oil production numbers as noted above: the inclusion of NGPLs and biofuels in the production numbers. The United States has been furiously drilling natural gas wells in the last few years and has increased its supply of NGPLs greatly. The production of crude oil proper has also been growing for essentially the same reason natural gas production grew: the deployment of hydraulic fracturing techniques and horizontal drilling to extract previously inaccessible deposits of so-called tight oil.

The results have been impressive, lifting U.S. production of crude oil proper (crude oil plus lease condensate) from 5.2 million barrels per day (mbpd) in 2005 to 6.5 mbpd in 2012. The latest available monthly production results are for September 2013 and put U.S. crude oil production at 7.8 mbpd.

But, it seems unlikely given the very steep production declines that existing tight oil wells experience--about 40 percent per year--that production will be able to scale that of the world's number one and number two oil producers.

Russia currently produces 9.9 mbpd of crude oil proper. Saudi Arabia produces 9.8 mbpd. Both numbers come from the EIA.

Could the United States produce more crude oil proper than these countries in the near future? Since we cannot know the future, anything is possible. But, consider that the United States has gotten most of the easy tight oil. Now, it must begin to rely on extraction of the hard-to-get oil. That oil will come out at a slower rate.

Meanwhile, the tight oil wells already drilled will continue to decline at colossal rates and their output will have to be replaced before any increase in production is possible. Trying to increase oil production under these circumstances can be likened to running up a down escalator since the declining production of existing wells cancels out much of the production from newly drilled wells.

If the United States were to attain the number one spot some day, it would be hard to maintain given the high production decline rates cited above.

5. The United States is on the verge of energy independence. This canard takes advantage of the lack of public awareness about U.S. energy resources. The country has long been self-sufficient in coal. This has never been an issue. It has also been nearly self-sufficient in natural gas, importing a little over 15 percent of its needs (almost all of it from Canada) from 1991 through 2011 according to the EIA. That percentage has trended down recently as U.S. production has increased. But the U.S. supply of imported natural gas was never in danger due to political disruptions or wars in faraway unfriendly countries.

So, it turns out that energy independence really means oil independence. On this count the country is still very far away from independence despite recent gains in domestic oil production. For the week ending December 20, the United States' net crude oil imports were 7.5 mbpd. The country would have to nearly double its rate of domestic crude oil production to meet its current consumption needs. That seems very unlikely given the production dynamics discussed above for tight oil which is where nearly all the growth in production is currently taking place.

6. The United States has 250 years of coal left. This claim keeps getting recycled even though a 2007 National Academy of Sciences study concluded that there was no basis for making such a claim. It suggested that the United States might have 100 years of coal left (assuming, improbably so, there would be absolutely no increase in the rate of consumption over that period). But, the report concluded that no comprehensive study of U.S. coal resources was currently available. The truth is nobody knows how much coal is left in the United States, nor how much of that might actually be accessible.

7. Peak oil is a myth. Peak oil is the idea that oil production inevitably reaches a maximum rate and thereafter begins an irreversible decline. It does NOT mean running out, but rather that production declines over time. It turns out that peak oil is actually an empirically demonstrated reality for every oil well, every mature oil field, and now for the majority of oil producing countries in the world. Those who tell us that peak oil is a myth can only be engaged in propaganda rather than a search for the truth. Ironically, many of them cite the upturn in U.S. production as "proof" that peak oil is a myth, forgetting that U.S. production peaked more than 40 years ago.

Oil is a finite resource and so, the real debate is over the timing of peak oil production for the world as a whole. Some say the peak is nearby. Others say it is two or three decades away. But no credible expert says that there will never be a peak.

The cases for and against a near-term peak would be difficult to relate in detail here. But, it's worth noting that the optimists have been consistently wrong about prices and supplies in the last decade, and those predicting a near-term peak have been much closer to the mark.

That doesn't mean that the peak must be nearby. But it suggests that the models and assumptions of the optimists are badly flawed.

There are so many other misconceptions about energy which remain that it would take a dozen seven-item lists just to begin to address them. But, I offer these seven as a starting point for a clearer and more honest discussion of our energy future in the coming year.

If Mexico is the next Brazil in oil production, brace for disappointment

Recent reforms that would open oil exploration and development in Mexico to major oil companies for the first time in decades has the media all atwitter about the prospects of a reversal in declining Mexican oil output and a possible doubling of production. The reforms have brought out comparisons with Brazil which has a similar arrangement in which the country's state-owned oil company works with major international oil giants to develop Brazil's petroleum resources. Adding to the frothy atmosphere, former Brazilian President Luiz Inacio Lula da Silva proposed a partnership between Mexico and Brazil to develop oil resources in both countries.

In a world with daily average oil prices hovering near record levels, such news might be welcome if only we could actually count on the accompanying optimistic production forecasts. But, it's instructive to look at what actually happened in Brazil since the time its potential as a major new oil producer was touted several years ago.

Brazil had discovered large oil deposits in ultradeep (30,000 feet down) reservoirs far offshore. In 2009, Petroleo Brasileiro SA (Petrobras), Brazil's state-owned oil company, announced that it would invest approxmately $175 billion in oil exploration over several years to boost Brazilian liquid fuel production from 2.4 million barrels per day (mbpd) in 2008 of oil, biofuels and other liquids to 4.6 mbpd in 2015, a move that would make the country a major oil exporter.

Let's see what kind of progress Brazil has made so far. In 2012 the country produced 2.65 mbpd of liquid fuels, making hardly any progress toward the goal announced for 2015. (The figures for oil proper, that is crude oil plus lease condensate which is the definition of oil, were 1.81 mbpd in 2008 and 2.06 mbpd in 2012.) In fact, instead of contributing to the worldwide supply of exports, Brazil remains a net importer of oil according to the U.S. Energy Information Administration (EIA), and those imports grew from 36,470 barrels per day in 2011 to 155,040 barrels per day in 2012.

The large Brazilian oil company OGX Petróleo e Gas Participações SA filed for bankruptcy recently "after disappointing output from offshore OGX wells set off a crisis of investor confidence," according to Reuters. It's no surprise that state-owned Petrobras is also finding it far more difficult to exploit its deep sea oil resources than originally anticipated. Admittedly, there are other problems at Petrobras. It has become a tool of economic policy for keeping unemployment low, saddling it with investments that it might not otherwise have made as a private company. But that doesn't change the fact that exploiting oil far offshore at extreme depths is difficult.

Mexico's state-run oil monopoly, Petroleos Mexicanos (Pemex), has seen its production drop from 3.45 mbpd of crude oil proper in 2004 to just 2.59 mbpd in 2012 according the EIA. Reforms that will give international oil companies new access to Mexican oil fields are supposed to change that trend. It's one thing to let private companies drill previously monopolized fields. It's another to raise overall nationwide production significantly as a result. Just ask the Brazilians. The easy-to-get oil has already been harvested in Mexico and Brazil. The hard-to-get oil comes next, and well...it's proving hard to get.

Will Mexico fare better than Brazil? Art Berman, a petroleum geologist and consultant who accurately forecast the bust for shale gas investors, offered this analysis in a recent email:

I have worked in Mexico since the early 1990s inside Pemex. There is a reason that no significant discoveries have been made since the 1970s--no reservoirs.

The Campeche Sound [in the Bay of Campeche] has reservoirs thanks to the biggest frack job ever, the Chicxulub meteor impact. The Golden Lane reef trend, discovered much earlier, has been fully explored with no new discoveries. Beyond that, almost nada.

The Eagle Ford Shale play [in Texas] extends into Mexico and, so far, all tests have yielded [natural] gas. There is a potential oil play in the Tampico area from the El Abra Shale that sourced the Golden Lane. The Chicontepec tight calcarenite play contains huge oil [resources] that no one has figured out how to exploit commercially as recently as in the last few years. The deep-water Gulf of Mexico has serious reservoir problems in Mexico.

Add it all up and we are left with the same sense that there should be huge remaining undiscovered reserves in Mexico that an awful lot of smart foreign companies (Amoco, BP, Chevron, Exxon, Shell, etc.) have been unable to discover working closely [through service contracts] with Pemex since the 1980s.

As far as the Citi [Citigroup Inc.] estimates go [projecting a doubling of Mexican production which is mentioned and linked above], mucho ruido, pocos nueces (much ado about nothing; literally, lots of noise, no nuts).

Jeffrey Brown, an independent petroleum geologist best known for his Export Land Model weighed in as well on Mexico's oil future. Brown's model, first released publicly in 2006, correctly forecast shrinking global net exports of oil in recent years. He believes that any effect of the Mexican reforms will be relatively small and delayed several years. He related his views in a recent email:

Regarding their [Mexico's] offshore potential, it's going to take a long time to work out the agreements, drill some wells and put the wells on line. I wouldn't expect to see any meaningful contributions from joint venture offshore projects until some time after 2020. Regarding onshore, [that] production could come on line sooner, but the agreements have to be made, and the per-well production rates are vastly lower than offshore. Also, I suspect that the production sharing agreements are going to be something more or less equivalent to a 50% royalty (or worse), versus much more favorable terms in Texas [which would make investment in Texas more attractive to major oil companies versus investment in Mexico].

Brown, who manages a joint venture exploration program based in Ft. Worth, also noted that "Mexico is on track to approach zero net oil exports in about six years (around 2019)." He continually reminds those making rosy predictions about oil exports for any exporting country that those countries tend to grow as oil revenues increase which means their thirst for oil also grows. That can leave less and less oil available over time for export. If the country's production is in decline, as has been the case with Mexico, exports decrease much faster than production on a percentage basis if domestic consumption grows in the face of declining production--a sort of pincer movement on oil exports.

It's possible that Mexico's production may grow somewhat as a result of the country's reforms. But, it is foolish to expect too much given what we've seen in Brazil to date. And, it is important to remember that production from currently producing Mexican wells is declining continuously making it necessary to drill a lot of wells just to maintain current production let alone increase it.

Anyone looking for oil exports or production from Mexico to reach their previous high marks would be wise to plan for a less than salutary result.

'Watch what we do, not what we say': Shell cancels U.S. gas-to-liquids plant

When civil rights advocates grew restless because of President Richard Nixon's right-wing rhetoric on the issue of desegregation, then-Attorney General John Mitchell told them, ''Watch what we do, not what we say.''

Those following the hype over America's supposed newfound abundance of oil and natural gas would do well to follow that advice when evaluating what oil and gas company executives and their surrogates say.

When Royal Dutch Shell pulled the plug on its U.S. gas-to-liquids project recently, the company offered the same explanation it used when it shut down its oil shale project earlier this year: Shell sees better opportunities elsewhere. This explanation--much like the I'm-resigning-to-spend-more-time-with-my-family explanation--tends to deflect questions about why things aren't working out.

What's not working out for Shell is a planned $20 billion plant in Louisiana designed to turn natural gas into diesel, jet fuel, lubricants and chemical feedstocks, products typically produced by oil refineries. The plug was pulled, however, while the project was still in the planning stage.

Shell did actually say a little more about why it is abandoning the project in this almost inscrutable piece of corporate prose:

Despite the ample supplies of natural gas in the area, the company has taken the decision that GTL is not a viable option for Shell in North America, at this time, due to the likely development cost of such a project, uncertainties on long-term oil and gas prices and differentials, and Shell’s strict capital discipline.

Now, here's the same paragraph translated into simple English:

The plant is going to cost a lot more to build than we thought it would. Natural gas prices are going up and could easily make it uneconomical to produce diesel and jet fuel from natural gas when compared to making them from oil. And, we don't have unlimited funds to spend on everything we think of just to see if it works.

Shell CEO Peter Voser has voiced doubts about the so-called "shale revolution" in the United States (which refers to advances in drilling technology that have opened previously inaccessible shale deposits of natural gas and oil to exploitation). In fact, Shell took a $2.1 billion write-down on its shale assets in the United States. In lay terms, the company had to reduce the value of those assets on its balance sheet to reflect reality. The company also sold small tight oil fields related to shale deposits, fields that it no longer wishes to develop.

Voser said he still believes Shell's remaining $24 billion investment in U.S. shale gas and tight oil will "be a success story for Shell." Three-quarters of that investment is devoted to natural gas from shale. But, Voser added that the potential for natural gas and oil from shale elsewhere in the world has been "a little bit overhyped" citing concerns specifically about Europe.

Now, because this rhetoric is coming from an oil industry CEO, we can assume that he is walking the line between saying things which will get him removed from the invitation lists of his fellow oil executives' cocktail parties--things otherwise known as the awful truth--and misrepresenting the facts to shareholders, which would get him into trouble in other ways.

But abandoning the gas-to-liquids plant speaks much more loudly than Voser's actual remarks. It means Voser expects that natural gas prices simply won't stay low long enough to make such a huge investment pay off. And, that means that he doesn't believe the hype about an ongoing glut of U.S. natural gas.

So, Voser directs Shell to abandon a gas-to-liquids plant, the profitability of which would be destroyed by high prices for the natural gas which the plant must purchase. At the same time, he has Shell retain most of its shale gas wells, a move which only makes sense if he expects U.S. natural gas prices to go higher. And, those prices will only go higher if there is increased demand or reduced supply, or a combination of both.

It's not hard to figure out the meaning of what Peter Voser is doing. But it is understandably difficult to shut out the constant din of abundance stories sponsored by the industry and its well-financed public relations machine--that is, until you understand that it's not what the industry says that's important, but what it actually does.
