What is Peak Oil?

The Real Science Team

Colin Campbell: "The term Peak Oil refers the maximum rate of the production of oil in any area under consideration, recognizing that it is a finite natural resource, subject to depletion."



1. Where does oil come from?

Hundreds of thousands of years ago, dead organic material from plants and small animals accumulated in swamps, riverbeds, and the bottom of oceans. These organisms are mixed with silt and mud, and gradually were buried under layers of sediment. These partially decomposed organisms then were subject to high temperature and pressure, and were transformed into liquid or gaseous material which we know as “crude oil” and “natural gas”.

Kenneth Deffeyes in his book Beyond Oil discusses the 7 factors that are necessary for the production of oil.

  1. Organic rich sediments must be present. It is not common to find organic rich sediment, less than 1% of all sedimentary rock contains more than 5% organic carbon.

  2. The organic sediments must be buried deeper than 7,500 ft. At this depth the temperature is about 175 °F, and the large organic molecules break into smaller molecules with 5-20 carbons. This viscous liquid is called crude oil. The top of the oil window is at 7,500 ft.

  3. The organic sediments cannot be buried deeper than 15,000 ft. Below this depth the molecules are broken down into gases with 5 carbons or less (natural gas). Natural gas and crude oil are usually found together.

  4. After the oil is liberated it flows upwards. Since oil is lighter than water, most oil flow upwards in seeps (90%) about 10% gets trapped underground in places that are not connected to the surface.

  5. The oil is trapped in rocks with significant porosity, known as reservoir rocks. The porosity must be greater than 5%. About half the world's oil comes from sandstone reservoirs. The other half comes from limestone (CaCO3) or dolomite (CaMg(CO3)).

  6. The pore space in the rock has to be connected so the oil or gas can flow through the rock. This is called permeability. The larger the grain size, the greater the permeability of the rock.

  7. At least one rock layer between the oil reservoir and the surface has to have a leak-tight seal, called a cap rock. Leak proof cap rocks are fine-grained mudstones and evaporative layers like halite (sodium chloride or table salt) and anhydrate (calcium sulfate).

The best areas in the world for oil are the Middle East, followed by west Texas and the North Sea. Overall oilfields cover less than 0.1% of the continents and continental shelves.

Discovery Oil – The American age of oil is thought to have started when Edwin Drake, who was looking for salt, drilled the first oil well in Titusville, PA in 1859. Today oil is discovered using seismic tools. On land, heavy truck vibrators are used to generate sound waves. At sea a rectangular series of detector are deployed, and compression waves are used to look at rock structure. This is called 3-D seismic exploration.

Oil Production

When a new oil field is discovered, the oil flows upward easily. This is the cheapest oil to extract. After about a quarter of the oil is extracted, the pressure drops and new methods are required to keep production high. This is generally done by injecting water into the oil field. The pressure from the water injection allows the oil (and natural gas) to rise to the top. At some point more water than oil is extracted from the oil field and separators have to be built to separate, natural gas, oil and water. In an old oil field production can be increased by horizontal drilling. A lot of methods have been tried to further increase recovery in an old wellfield, but the best one that has been found is to inject carbon dioxide into the well.

The consensus is that these new technologies – horizontal wells, water injection, etc. – increase the rate at which oil can be produced, but do not increase the amount of oil that is ultimately recovered.

The graph on the left is an idealized graph of production in an oil field. Initially production rises quickly, then peaks, and then declines.

2. Peak oil in the US

The US was the world’s major producer of oil in the 1950s and 1960s and the oil fields in West Texas rivaled those in Saudi Arabia. A geologist named Hubbert began to think about how much oil remained.

The graph on the left shows the amount of oil discovered in the lower 48 states.

He then began examining the amount of oil produced. By graphing the knowing the amount of oil produced a year and the cumulative oil production the graph on the right can be drawn (P = annual production, and Q= cumulative production).

The brown line is an idealized graph. Where the graph intersects the axis is the total amount of oil available from the oil field.

The peak of oil production would occur when one-half of the oil is removed from the oil field.

He then correctly predicted that oil production in the US would peak in early 1970s. The graph below shows that he was right on target.

Today world oil production has increased to about 85 million barrels a day. However, demand is increasing at a rate of about 2 percent a year. The rate of discovery of new oil field is not keeping pace with the rate of consumption.

The production from all oil fields proceeds in a similar manner. World oil production is a combination of the production from all the oil fields in the world. World oil production should also follow a bell shaped curve.

The actual date at which world oil production will peak is controversial with various experts putting the dates anywhere from 2004 to after 2020, but at some point the amount of oil produced in the world will peak, and then less oil will be produced each year after that.

Since oil is such a major part of our economy it is important that we begin planning the development of alternatives soon. Many experts have pointed out that there can be a smooth transition from oil to alternative energy sources if we have 20 years until oil peaks. If we have only 10 years until oil production peaks, then there will be substantial disruption of the economy. If we have less than 10 years, the disruption will be more intense.

I began my data processing career as a programmer at Amoco Production Company in Tulsa, writing programs to analyze seismic traces -- the digital representation of the vibrations set off by an explosion or vibroseis device. It was most interesting work. Then I moved on eventually to lead Amoco's flagship computer mapping system, incorporating civil and lease boundaries, land-water boundaries, and subsurface contour lines. That was even more interesting.

If enough people can grasp the concept of peak oil and the impact that a sudden decline in production could have on world economic stability, perhaps the efforts necessary to prevent the problem by developing alternative fuel sources and proper conservation of oil reserves would be seen as the critical issues they are.

As Wes so eloquently explains it, that's the same logic we need to deploy in enlightening people about Global Warming.

This entry is great- thanks for it, Real Science-

check out Greg Palast's book Armed Madhouse for some interesting info about oil & empire.

I love Greg Palast, as does the author of this letter in response to Palast's take on "Peak Oil." But for those who have read his book, which gets into this issue, I think this open letter, by Richard Heinberg, is a well-written, thoughtful one to keep in mind as well.  It also is a good explanation (to further Judy's) from the side of those who think "peak oil" is indeed something we need to be thinking very seriously about:

An Open Letter to Greg Palast

by Richard Heinberg

Dear Greg,

Congratulations on your new book, Armed Madhouse. As with your previous work, I admire your dedication in exposing the machinations of government and corporate miscreants.

However, this time around you’ve also taken a potshot at a target that I happen to know a good deal about and have been closely involved with for a few years—the efforts by a growing number of analysts to forecast the arrival, and prepare the world for the consequences, of Peak Oil. In this instance I think your negative comments about Peak Oil and those of us who study it are not well informed. Ordinarily I wouldn’t respond to an ill-considered statement by an otherwise admirable author; but unfortunately you go on for several pages on this theme, and I’ve started receiving e-mails from folks who are troubled by what you said. In my many years of fighting to protect our planet from environmental destruction, I have learned how important it is to make sure that our supporters have the most accurate information possible. Time and again, I have seen our opponents seize on internal disagreements as wedges in their drive to weaken and damage the credibility of the environmental movement. I feel the responsibility to help sort out the factual issues in this instance particularly strongly because you have worked so hard to earn your reputation as a truth-teller in these perilous times.

First let me make clear where I’m coming from with my critical analysis. Before you assume that, just because I disagree with you, I must therefore be secretly in the employ of the Heritage Foundation or some nefarious corporation, I should point out that in my own recent book, Powerdown, I take the Bush administration to task as vehemently (if not at so great a length) as you have done. And I teach in a program on “Culture, Ecology and Sustainable Community” at a small, far-left liberal arts college where you have lectured. So we are in other respects natural allies.

In your book, you place your critique of Peak Oil in the context of scathing attacks on the Bush energy plan and the oil companies’ enormous ongoing political influence. These are serious problems and you deal with them skillfully and entertainingly. But, in contrast to these subjects, the Peak Oil discussion is more about science than politics, and when it comes to science, catchy phrases don’t count; only a careful weighing of evidence does. I’m sorry to say that you don’t appear to be fully informed about the terms and history of this debate.

Let’s start with your description of the work of the late geologist M. King Hubbert and the study of oil depletion.

On page 108 you pretend to summarize Hubbert’s 1956 world forecast for global oil production as follows:

Sometime during 2006, we will have used up every last drop of crude oil on the planet. We’re not talking “decline” in oil from a production “peak,” we’re talking “culmination,” completely gone, kaput, dead out of crude—and not enough natural gas left to roast a weenie.

But “Decline” and “peak” are precisely what Hubbert was forecasting—and not in 2006, but around the year 2000, as shown in the graph you reproduce on page 111. How could you possibly get the essential terms of the debate so plainly wrong? Frankly, I’m amazed. Maybe you got hung up on the word culmination (which, among other things, means “the highest point achieved by a celestial object in the night sky before it begins its descent”—a good metaphorical usage of the term in this instance). But even so, how could you have completely missed the context in which Hubbert used that word—a discussion that was entirely about “decline” and “peak”?

This is a core misunderstanding that crops up repeatedly in your treatment of the subject. In your caption to Hubbert’s graph on page 111, you say, “Note: the total sum of oil is 1,250 billion barrels—which runs out in 2006.” The graph clearly shows production peaking around the year 2000—which it probably would have done if not for the oil shocks of the 1970s, which Hubbert could not have foreseen—and still shows oil being produced in the year 2200. The oil industry is fond of citing historical claims from the 1890s that “oil will run out in 10 years” as a way of discrediting current concerns about Peak Oil, and your accidental misinterpretation of this graph unfortunately echoes this oil industry line.

Hubbert just flat-out never predicted that oil would “run out,” nor has any oil depletion analyst that I’m aware of predicted oil “running out.” There will always be more oil in the ground, just not enough at a cheap enough price to sustain the current world oil demand. Debaters would call putting the phrase “running out” into the mouths of oil depletion analysts a “straw-man” argument: you wrongly attribute an absurd statement to your adversary, you disprove the absurd statement, and the audience cheers—except for the frowning woman in row 12 who happens to be taking a course on critical thinking.

In fairness, you seem to be saying that the total amount of oil represented under the curve Hubbert drew is too small (which it was); thus, if we take that amount as fixed and subtract the oil actually used so far, what’s left won’t last us till the end of this year.1 Well, according to my calculations the world still has a few years to go even if we do pursue this useless thought exercise, but that’s mere quibbling. The point you wish to make is: Hubbert got it wrong!—he underestimated the global amount of ultimately recoverable oil. Therefore we should pay no attention to him.

But hang on—didn’t Hubbert get it amazingly right when in 1956 he predicted that US oil production would peak around 1970 (which it did)? You don’t mention that. Why was one prediction spot-on, the other less so? Well, in 1956 the US was much more thoroughly explored—and depleted—than the rest of the world. The method Hubbert had developed for predicting peaks worked well in the US in 1956. And it seems to be working well for other large provinces (such as the North Sea) where extraction has proceeded sufficiently far so as to establish a linear trend.2 If you want to understand the method better, I recommend a careful reading of Chapter 3 of Kenneth Deffeyes’s excellent book Beyond Oil. In the decades since Hubbert made his initial forecasts, world depletion has more than caught up with where US depletion stood back then. Thus a Hubbert-type forecast for world peak is much more likely to be correct today than it was in 1956, given the data available.

These are only a couple of examples; you go on from there. Sentence after sentence betrays ignorance of the scientific matters at issue.

There’s just no hope of setting the record straight on everything. Therefore the best I can do is to address what I take to be your three core assertions.

1. King Hubbert was a shill for Shell

Just because someone works for a company or agency, that does not mean that everything the person writes or does is in the service of the institution. But you assume the worst of Hubbert in this regard, and your line of reasoning goes like this:

King Hubbert worked for Shell Oil research labs during the years when he made his predictions about the US and world peaks in oil production. That means he was being paid by Shell. That means that the work he was doing must have been suggested by Shell, approved by Shell, and in Shell’s interest. Therefore the entire Peak Oil notion is one created, bought, and paid for by Big Oil.

This might be characterized as argument by innuendo. The first two sentences in the preceding paragraph are demonstrably true; the second two are pure conjecture. What does the evidence say? I challenge you to produce any account of the events that differs substantively from the one Ken Deffeyes (who knew Hubbert well) offers in his book Hubbert’s Peak. Not only did Shell not suggest the line of inquiry that led to Hubbert’s famous depletion curve, but when he came up with it his bosses tried to prevent him from talking about it. The general reaction in the industry was anything but supportive. Deffeyes puts it this way: “It was as if a physician had diagnosed virulent, metastasized cancer; denial was one of the responses.” Hubbert was repeatedly attacked from within the industry.

Well, you might say, maybe this was all a clever plot. I suppose there’s no way to prove whether it was or wasn’t. But we might profitably inquire: Just what kind of man was Hubbert? Was he the sort to participate in an industry conspiracy?

Not according to the people who knew him.

I cannot tell if you talked to people who knew Hubbert and worked with him—before slandering him by innuendo. I have spoken to a few such people, including several of his former students, a co-worker, and a close relative. The picture they paint is of a somewhat imperious, pig-headed genius who had gradually come to the conclusion that the world was headed in the wrong direction fast because of its dependence on fossil fuels. He was a respected geologist responsible for other important contributions in his field. In addition to working for Shell, he also worked for the USGS and taught at several universities. He did not suffer fools lightly, nor did he show much interest in climbing corporate or academic ladders. This would not appear to be the sort of person who would stake his career on a bogus hypothesis just because a temporary employer told him to.

As a current and apt analogy, consider the case of James Hansen of NASA, who has spoken out strongly about the dangers of global greenhouse gas emissions. The man works (indirectly) for the Bush administration; therefore should we assume that he is secretly doing Dick Cheney’s bidding by needlessly scaring the nation about climate change? Of course that’s absurd: the Bush administration has tried to muzzle Hansen—just as Shell tried to muzzle Hubbert.

Innuendo is just not a proper form of argument.

You point out that King Hubbert supported nuclear power. I happen to disagree with him on that issue—as I also do with biologist James Lovelock, who likewise supports nukes.

But you make it sound as though Hubbert came up with his oil depletion forecasts as a justification for Shell’s nuclear program. There is no evidence for that assertion, as far as I’m aware. Hubbert’s colleagues tell the story differently: Once he had calculated that global oil production would peak in a mere half-century, Hubbert realized that the world would need a new non-fossil source of energy. At the time (remember, we’re talking about events in the 1950s), nuclear power seemed the only realistic alternative. Later he threw his support behind solar power, when that technology began to show promise.

In retrospect, it seems to me that King Hubbert was one of the most visionary scientists of the twentieth century. You may disagree. But ultimately there is only one question about Hubbert that really matters in the current discussion: Did he make an important contribution to our understanding of oil depletion? On that point, there is widespread positive agreement. Not only has Hubbert’s method produced results that have been confirmed by events, it also yields forecasts that mirror ones generated through entirely different methods.

Chris Skrebowski, the editor of Petroleum Review, has been tracking decline rates from producing oilfields and comparing those numbers with new production capacity expected from the various new projects in which the industry is investing. He calls this a “bottom-up” method (because it requires patiently assembling and crunching data from many sources), in contrast to Hubbert’s “top-down” graphs. I doubt if Chris has ever drawn a standard Hubbert curve, but he has come to essentially the same conclusion as those who do: he expects global oil production to peak around 2010.3

Was Hubbert right about everything? Obviously not. We’ve already seen that he underestimated the global amount of ultimately recoverable oil, and why he did so—because he was working with early data. However, some of your own statements seem to be inaccurate in ways that are harder to account for.

2. The oil companies are behind today’s Peak Oil warnings

You point out that Chevron has recently taken out ads declaring that world oil discoveries are down. Chevron is pushing Peak Oil! Therefore the latter must be a corporate plot whose purpose is to drive up oil prices and line the pockets of greedy executives. Here’s the relevant passage from your book:

So who’s selling us Peak Oil today? The operator of the supertanker Condoleezza has been running an extravagant advertising blitzkrieg to tell us: We’ve peaked! “The world consumes two barrels of oil for every barrel discovered!” That’s just the billboard. Their double-page spread in Harper’s is even more hysterical: “The fact is, the world has been finding less oil than it’s been using for twenty years now.” Unfortunately, that “fact” isn’t a fact at all—reserves rise year after year—and those facts don’t change because Chevron paid my magazine to print it.

Actually, Chevron—rather than being at the forefront of the Peak Oil discussion—is late on the scene: independent and retired geologists have been talking about this problem for years; the companies have generally been discouraging the discussion in every way possible. I know because when I lecture about the subject, the people I find myself debating are usually industry PR reps (including, just recently, one from Shell), while the folks who offer the most informed encouragement are nearly always retired or independent geoscientists. Chevron still hasn’t used the “P” word, and is just saying that oil will get more expensive from now on.

Of all the oil companies, Exxon is leading the charge in opposing Peak Oil. You may remember that Exxon also spearheaded the industry’s effort to deny the link between climate change and carbon emissions—and in fact is still doing so. Here are passages from an Exxon ad, titled “Peak Oil: Contrary to the Theory, Oil Production Shows No Sign of Peak”:

Will we soon reach a point when the world’s oil supply begins to decline? … So goes the theory. The theory does not match reality, however. Oil is a finite resource, but because it is so incredibly large, a peak will not occur this year, next year, or for decades to come.4

The case made in the Exxon ad is essentially the same one you outline in your book. So which company is telling the truth and which is engaged in a disinformation campaign? One of the problems with argument by innuendo is that it often requires us to speculate about other people’s motives. The only question that really matters here is, which line of argument is correct? And the only way to make an informed judgment in that regard is to examine and weigh the evidence and the quality of reasoning on each side.

Well, what about Chevron’s statement that “the world has been finding less oil than it’s been using for twenty years now”? You say that “isn’t a fact at all.” Not if one conflates actual discoveries with reported reserve additions—but these are two very different animals. Reserve additions occur for a number of reasons—some political, some simply having to do with SEC reporting rules. Sometimes they reflect recent discoveries, but this is less the case as time goes on. The Royal Swedish Academy of Sciences, in a recent publication titled “Statements on Energy,” describes the situation this way:

In the last 10–15 years, two-thirds of the increases in reserves of conventional oil have been based on increased estimates of recovery from existing fields and only one-third on discovery of new fields. In this way, a balance has been achieved between growth in reserves and production. This can’t continue. Fifty percent of the present oil production comes from giant fields and very few such fields have been found in recent years.5

In fact, recent oil discovery figures are much worse than Chevron makes them out to be: the Chevron ad you quote says that two barrels of oil are being extracted for every one discovered; for the past few years the ratio has actually been more like four, five, or even six to one.

But why does it matter if discoveries are down, when reserves are still growing? Doesn’t the fact that global oil reserves are at record highs preclude a near-term peak in production? Not necessarily. There are many examples we could explore—after all, over half of the world’s producing nations are in decline, most of them irreversibly so. Did reserves drop substantially in these nations before they hit their production peaks? Certainly not in the most important and well-documented case—that of the US. Here, while discoveries of new fields peaked in 1930, reserves as of 1970 were at record levels, as was production. Therefore it came as a surprise to nearly everyone (except King Hubbert) when production levels began to drop the following year, despite every effort on the part of the industry to keep them soaring. US production in the onshore lower 48 is now back down to about where it was in 1940.

Is Chevron right, or is Exxon right? I’d say that what Chevron is telling the American public is closer to the truth. But only time and careful analysis will tell. Speculating on the companies’ motives may be easy and entertaining, but it is probably the least helpful way of getting at the truth in this instance.

3. The world has oodles of oil—and most of it’s in Venezuela

As I read and re-read the pages in which you claim to show that “the Peak Oil crowd is crackers,” I am disturbed to see how much your case relies on guesses about what’s going on in the minds of oil company executives, and how little discussion you provide of the sea of facts and analysis that are publicly available. It’s in your Appendix, “Return to Hubbert’s Peak: Why Palast Is Wrong,” that you finally do present a brief analytic case. The factual core of your argument (still confined to only a few sentences) seems to be that the world simply has enormous amounts of oil, and thus a near-term peak is unthinkable.

Price, you say, makes all the difference:

World oil reserves, officially measured at 1.189 trillion barrels, are probably, as one of Mr. Hubbert’s protégés stated a few years back, grossly overstated—if you assume oil selling at $10 a barrel. But kick the price up to a post-invasion $50 a barrel, and the world reserves are wildly understated.

Yes, the world has more oil available at, say, $50 or $70 a barrel than at $10 or $20. Everyone agrees; that’s a truism in the industry. But there’s no simple mathematical relation between increasing the price of oil and increasing the size of estimated reserves. Doubling the price doesn’t double the reserves; it merely makes a few out-of-the-way known reserves more attractive.

The all-important question is, how much oil can the industry pump every day (that is, at what rate can that oil be produced)? That’s what the debate over Peak Oil is all about—not reserves or amounts ultimately recoverable, but flow rates. When will the flow rate that the industry can possibly attain reach its maximum?

With prices high, you say, hundreds of billions of barrels of oil from the tar sands of Canada and from the heavy-oil fields of Venezuela become economical to produce. Right again, though this is not conventional oil we’re talking about, but materials that have to be transformed into synthetic petroleum using energy-intensive processes. Again, the real question is, at what rates? Canada is currently extracting a million barrels a day from the tar sands; Venezuela is pulling a little over half that amount from the Orinoco belt. These numbers are expected to climb—and then level off. Why? Because the process of producing synthetic oil from these low-quality hydrocarbon sources is constrained by physical factors that just do not respond much to economic stimuli. Canada needs lots of fresh water and natural gas to make oil from the tar sands, and both are in short supply. The best published forecasts say that, regardless of the price of oil, flow rates there will max out at about three to five million barrels per day by 2025—a generous amount in terms of the benefit to Canada’s economy. But this is not nearly enough fuel to satisfy the US habit of over 20 million barrels per day—and crucially, it’s not enough to make up for expected declines from the world’s giant and supergiant conventional oilfields once the latter begin their inevitable declines—as they are doing now. There are only about a hundred of those big fields that, collectively, yield roughly half the oil extracted today. Nearly all are old (found in the 1940s through the 1970s), and we’re seeing that, with the newer water-flooding recovery methods, when decline comes it can hit unexpectedly and with catastrophic swiftness—as it did in the Yibal field in Oman, which peaked at 250,000 barrels per day in 1997 and is already down to less than 80,000 b/d.

The situation in Venezuela is similar to that in Canada.

All of these questions have been discussed, dissected, analyzed, and graphed endlessly. Yes, it’s theoretically possible to build nuclear reactors to cook the tar sands—but the practical challenges in that case are prohibitive, as the tar sands are geographically extensive and each nuclear plant would be able to heat only a limited area; that means lots of expensive nuke plants with useful lifetimes limited by the amount of bitumen within easy reach. It’s already costly to make oil from bitumen; add hundreds of billions of dollars in nuke plants and the exercise quickly becomes an investor’s worst nightmare.

I could provide more details, but what’s the point? We are breaking no new ground here. Every serious analyst I know who is predicting a global oil production peak between now and, say, 2012 is thoroughly familiar with the standard free-market argument about higher prices stimulating more production, and with the published reserves figures for tar sands, heavy oil, shale oil, and so on. All of this has long ago been taken into account.

After writing the previous paragraph, I went back to your book to see if I had missed something. But no—the rest is all guesswork: Why did the US really invade Iraq—was it to close down the oil spigot and raise prices? Is Shell Oil Company using its ads to try to scare us into supporting further invasions of the Middle East? Did Hubbert time the release of his famous paper to coincide with the overthrow of Iran’s Mossadegh and the closure of the Suez Canal? I honestly don’t know whether you’re right on any of these points. I just don’t have enough information to go on—even though I’ve spent the past few years devoting considerable time each day to studying the oil industry and following the same press reports you must have read.

What I do know is that the arguments you have brought up in order to “debunk” the Peak Oil thesis are not up to your usual journalistic standards.

* * *

In an apparent nod to folks like me, you write, near the very end of your book, “Some environmentalists have echoed the ‘peak oil’ theorem in the false hope that oil companies’ raising prices will lead to conservation. Fat chance.” As you might imagine, Greg, it gives me no pleasure to see the efforts of five years (and the motives for those efforts) misrepresented and flushed away in a couple of snide sentences. The truth is, I write and speak about Peak Oil because I believe that the evidence for it is overwhelming, that it will have a devastating impact on everything we hold dear, that there are actions we can take to mitigate that impact, and that those efforts won’t be undertaken unless the public is alerted.

The problem of Peak Oil has been acknowledged by environmentalists like Bill McKibben and Lester Brown, by public figures like Bill Clinton, by international affairs experts like Michael Klare, and by both oil industry insiders and severe critics of the industry. The world is deeply dependent on cheap, abundant oil, and we are seeing the end of cheap oil unfolding before our eyes. The process of economic adaptation is not going to be quick or easy. We’re all going to have to work together on this—whether we think of ourselves as liberals or conservatives, whether we live in rich or poor countries, and regardless of our area or level of expertise. Naturally, there will be disagreements along the way, some folks will try to take advantage of the situation, and we’ll need investigative reporters like you to help keep everyone informed and honest. But if we don’t commit ourselves to trying to work together, things could get ugly—much uglier than they already are.

I’d be happy to discuss the evidence with you at greater length, and I’d be happy to point you toward some good source material, most of it untainted by association with any oil company.

I refuse to speculate about your motives. I assume they are the best. Therefore I also assume that, if shown to be incorrect, you will set the record straight. Everyone is wrong sometimes, and when one is publicly wrong, there is a strong incentive to retrench. Being wrong in print is the worst case. But sometimes it happens, and when it does the best thing is to admit it and move on.

On the other hand, you may wish to write a rebuttal. If so, might I suggest some sources for research on anti-Peak Oil arguments? Try these:

  • Exxon (as discussed above);
  • Daniel Yergin, chairman of Cambridge Energy Associates and author of The Prize and The Commanding Heights—the latter a book that’s on every neocon’s short list of favorites; and
  • Jerome Corsi, proponent of the “abiotic oil” hypothesis and primary architect of the Swift Boat disinformation campaign against John Kerry.

Now, these people’s assertions have already been countered by competent scientists, so if you want to make a real contribution to the discussion, you will need to take account of those counter-arguments and bring the debate up to a still higher level. That will require familiarizing yourself with an extensive literature.

But I would greatly prefer it if you would simply acknowledge that thousands of Peak Oil activists around the world are in fact devoting themselves to a worthy cause. Most of them are working hard to wean themselves and their local communities from oil dependency.

In my view, the best large-scale strategy for going forward would include the international ratification of an Oil Depletion Protocol mandating reductions in petroleum production and imports. Such an agreement would tend to stabilize prices, reduce international competition and conflict, and conserve the resource base. If nations observed such a Protocol, it would also help with the problem of greenhouse gas emissions, as long as it was accompanied by a strong Kyoto-like accord. A coalition of individuals and groups is forming in order to persuade the nations of the world to adopt such a Protocol.6

I’d really like to have your support on the Protocol and on grassroots Peak Oil efforts, Greg. A lot of people listen to what you have to say, and a lot is at stake.

Sincerely,

Richard

Hubbert estimated that the Earth would eventually yield about 1,250 billion barrels of regular oil (excluding tar sands, oil shale, and so on); many current estimates of global recoverable regular oil are in the range of 2,000 billion barrels, or about 800 billion barrels (65%) higher. The world has consumed just about 1,000 billion barrels so far.

Thanks- yeah- there does seem to be some controversy (I don't particularly have an opinion on it or know a whole lot about it, so I'm happy to see this here) or at least Palast's stance seems markedly different. I look forward to reading the above when my attention is less split... thanks for posting it.

What I find fundamentally confusing is the push by automakers towards giant Canyonero types of SUV's if peak oil is around the corner- this just doesn't make sense, but- oil is a "boom & bust" wild wild west type of thing at heart, I guess. I'm also "suspicious" about supply getting tighter & tighter & more expensive to extract, etc.

via energybulletin.net, I see that Bloomberg just published an article on Peak Oil:

http://www.bloomberg.com/apps/news?pid=20601109&sid=arur.i7moHMs&refer=home

From the article:

...As energy prices soar and violence convulses the Middle East, the peak-oil movement -- an unlikely alliance of geologists, physicists, oil industry consultants and environmental activists -- is winning converts. Peak-oil ideas are bubbling up from scientific journals and offbeat Web sites, much the way warnings of global warming did a decade ago. For the first time, the peaksters have begun to grab the attention of Washington and Wall Street.

The editors at energybulletin also noted this comment on the Bloomberg article by a blogger:

There is a remarkably detailed, thoughtful, and sober-minded article up on Bloomberg looking at peak oil advocates ("peaksters") and critics, and their conflicting views on the future of energy. The article is too big to even begin to summarize, so I strongly recommend you read the whole thing.

I think it's good to recall that one of our heroes, George Soros - a progressive's progressive - saw the terrible ride ahead for some currencies and made a fortune by anticipating how that would shake down, even as what did ultimately happen to the currencies hurt so many.  Similarly, some who take "peak oil" seriously as something in the not too distant future will indeed turn their attention to where there will be money to be made (some in the supplies themselves, some in alternatives, various other commodities, etc.). 

I know many think that either a lot of error or even full-out conspiracy, generating mostly unfounded supply concerns, is all that could really be behind rising prices for oil, gasoline, natural gas, and the products those products feed into.  And no doubt, even if there are things happening fundamentally in terms of supply, there is currently a "risk premium" that is occurring in the market at this time in anticipation of this or that or in quick response to an event here or there, market dynamics that may settle down over the relative short term.

Yet it must also be conceded that *if* there is actual fundamental supply problems in the face of continuing and even expanding demand, that, too, would drive prices up - regardless of people who make a profit from such a dynamic.   Those investors also, by the way, will need to keep in mind the other side of soaring profits - *demand destruction* (which if relatively abrubt can make for abrupt and plummeting profits, which also means cascading *divesting*, and its own set of negative feedbacks).

I remember having a very hard time seeing - within the movie *The Corporation* - a stock broker speaking about the giddiness investors were feeling, himself included, in concert with the 9/11 attacks due to what that meant for the price of gold and other like investments that were to be beneficially impacted.  Many people made a fortune that day on many investments.

I would not begin to dispute that the concept of Peak Oil is a reality but the price escalation per barrel and supply problems and escalating prices at the pump are due to the greed of commodity brokers artifically jacking prices and the oil companies mimimizing supply and increasing their profit margins at the refinery.

An oil company with existing wells pumping oil that costs about $15/barrell doesn't suddenly cost $70 because of some crooked brokers desire to make money.

Thanks for posting your concerns and point of view.  I realized after posting the above comment, I over-simplified the side of the debate that is concerned about what part of all of this might be artificially contributed to, for certainly greed and power-seeking can't be counted out as powerful potential factors/dimensions in the overall huge and complex set of circumstances currently playing out.

I wish I were much more of an expert along the lines that could truly and thoroughly discuss what if any limitations there might be to the power of greed in all of this, and, therefore, the capacity and limitations of the big oil companies, and the like.  But I'm certainly not in the position to do that.  So, of course, neither am I in the position to dismiss, out of hand, such concerns...

My main point was that *if* there are indeed some fundamental problems with supply currently or soon to be happening, which many reasonable and knowledgeable people consider to be the case, it also follows that price will be affected and fortunes will be made.

There's definitely a fear component in oil pricing, but basically oil is priced not based on the cost of oil produced wherever it came from, but rather on the future cost of replacing the oil sold. And since the future is always uncertain, an element of the pricing is fear surrounding the ability to get oil down the road.

There was a report on CNN a little bit ago about peak oil.

They were talking about a big oil shale reserve in CO (didn't quite catch the name)...said it was the largest in the world...enough oil there for a 100 year supply (except when the man being interviewed said that his eyes shifted to someone off camera...hmmm). Anyway..

Apparently heaters are inserted to bring the oil to the surface so they can extract it and this oil is easily refined.

Shell Oil is doing the preliminary work now and profess to be studying how this will affect the ground water(?). Talking about being environmentally sound...hmmmm....

The decision on whether this can be done should come in 2010 and the gas will be on the market in 2018.

Due to my distrust of oil companies and the so-in-so's in charge, I'm a little skeptical this might be a boondogle. What do you experts think?

On another note...the mention of horizontal drilling reminded me of the scuttlebutt way back that the reason Saddam invaded Kuwait is because Kuwait was horizontally drilling into Iraq and stealing their oil. Wonder if there was any truth to that??

Now...because I was reading this very interesting diary while eating my lunch earlier, my ears pricked up when they discussed this on CNN. Made me stop what I was doing and sit down to listen. Thanks...science "guys"...learned something new today!

are many. It requires a lot of water, you need to use natural gas (which is getting more expensive), and a lot of CO2 is released to the air. My guess is that oil shale will never be a major energy source. We need to fine renewable sources of energy in the future.

This doesn't apply directly to a discussion about oil shale, but many of the same suggestions have been made about the tar sands of Canada and Venezuela, which are huge and are now being developed, full steam ahead. It is here that he discusses the importance of actual production rates, which is what is the most important factor to supply; not what's actually in the ground, but what can be produced from the ground and at what rate:

Yes, the world has more oil available at, say, $50 or $70 a barrel than at $10 or $20. Everyone agrees; that’s a truism in the industry. But there’s no simple mathematical relation between increasing the price of oil and increasing the size of estimated reserves. Doubling the price doesn’t double the reserves; it merely makes a few out-of-the-way known reserves more attractive.

The all-important question is, how much oil can the industry pump every day (that is, at what rate can that oil be produced)? That’s what the debate over Peak Oil is all about—not reserves or amounts ultimately recoverable, but flow rates. When will the flow rate that the industry can possibly attain reach its maximum?

With prices high, you say, hundreds of billions of barrels of oil from the tar sands of Canada and from the heavy-oil fields of Venezuela become economical to produce. Right again, though this is not conventional oil we’re talking about, but materials that have to be transformed into synthetic petroleum using energy-intensive processes. Again, the real question is, at what rates? Canada is currently extracting a million barrels a day from the tar sands; Venezuela is pulling a little over half that amount from the Orinoco belt. These numbers are expected to climb—and then level off. Why? Because the process of producing synthetic oil from these low-quality hydrocarbon sources is constrained by physical factors that just do not respond much to economic stimuli. Canada needs lots of fresh water and natural gas to make oil from the tar sands, and both are in short supply. The best published forecasts say that, regardless of the price of oil, flow rates there will max out at about three to five million barrels per day by 2025—a generous amount in terms of the benefit to Canada’s economy. But this is not nearly enough fuel to satisfy the US habit of over 20 million barrels per day—and crucially, it’s not enough to make up for expected declines from the world’s giant and supergiant conventional oilfields once the latter begin their inevitable declines—as they are doing now. There are only about a hundred of those big fields that, collectively, yield roughly half the oil extracted today. Nearly all are old (found in the 1940s through the 1970s), and we’re seeing that, with the newer water-flooding recovery methods, when decline comes it can hit unexpectedly and with catastrophic swiftness—as it did in the Yibal field in Oman, which peaked at 250,000 barrels per day in 1997 and is already down to less than 80,000 b/d.

The situation in Venezuela is similar to that in Canada.

All of these questions have been discussed, dissected, analyzed, and graphed endlessly. Yes, it’s theoretically possible to build nuclear reactors to cook the tar sands—but the practical challenges in that case are prohibitive, as the tar sands are geographically extensive and each nuclear plant would be able to heat only a limited area; that means lots of expensive nuke plants with useful lifetimes limited by the amount of bitumen within easy reach. It’s already costly to make oil from bitumen; add hundreds of billions of dollars in nuke plants and the exercise quickly becomes an investor’s worst nightmare.

I could provide more details, but what’s the point? We are breaking no new ground here. Every serious analyst I know who is predicting a global oil production peak between now and, say, 2012 is thoroughly familiar with the standard free-market argument about higher prices stimulating more production, and with the published reserves figures for tar sands, heavy oil, shale oil, and so on. All of this has long ago been taken into account.

Yes, it's good to learn about these various unconventional supplies that are becoming more attractive now that the cost for the techniques to get at them are recoverable (at least monetary costs; the environmental costs are another thing entirely).

With these kinds of resources, the key seems to be potential daily "flow rate" and not simply the amt available, which indeed does seem to be huge.  The open letter I posted above, by someone much better versed in all of these things, discusses such unconventional resources now beginning to be tapped.

There are similar problems with tar sands as with oil sands - need lots of water, need natural gas to process them, leave lots of waste, and produce lots of CO2. They have been trying to make oil out of tar sands for decades, and it hasn't worked yet.

The problem with tar sands, oil sands is that it requires a lot of energy to covert them to a useable product. If you don't have cheap oil, what energy source are you going to use?

Submitted by ms in la on September 2, 2006 - 3:49pm.

in the past year or so regarding this process Judy? I may be mistaken, but it seems I saw some TV show that was discussing some newer procedures being used to excavate oil from the Canadian sands... Probably using lots of excess energy in the process as you say... but it seems they had minimally made it more efficient or doable in any case.

Know anything about that? It was one of those late night documentaries so I may have dreamt it! ;-)

that they are making some progress in Canada using the oil sands. We will have to wait see, but the look at the figures:

Current oil use worldwide: 84mbl/day. Projected for 2015: 105mbl/day.
Current oil sands production: 1mbl/day. Projected for 2015: 3mbl/day.

Yeah, doesn't look like a whole lot of surplus will be generated there.

The "in situ" process w/ oil shale looks daunting as well:

http://www.craigdailypress.com/section/frontpage_lead/story/22983 (which discusses the "in situ" process, the "newest" technology being tried w/ the oil shale by Shell at the moment)

This is in experimentation, and just these few spots are going to take years to work with.

And eventually, if they want to have this kind of process make any regular and substantial production (that's also the #1 question, how much oil per day can such a process produce?), this has to be done in proximity to all of the shale they want to work with - years in each case: the freezing, the heating, etc., and all of which will take it's own share of energy to make happen.

As Judy and the open letter pointed out - even the huge tar sands in Canada and Venezuela are not expected to be able to rise to a daily production level much greater than what was mentioned, regardless of how long into the future they might be able to produce a particular amt.

Conventional oil - particularly "sweet crude," which refines the easiest and comes out of the ground in the easiest manner has an extraordinary energy ratio (the energy needed to go into the process to extract the energy received). I want to say it's 1:10, but it may be even much better than that. Judy?

When you get into the unconventional methods, that ratio changes drastically.

And again, what's most significant issue - well, that's if you put aside all the issues of the environment - is the net daily production, and how well it offsets daily production decline elsewhere

Submitted by Judy from NJ on September 2, 2006 - 8:51pm.

for oil used to be about 100:1 (get 100 units for 1 unit of input) in the beginning. The concensus now with water injection, horizonal wells, etc. is that the ratio is about 10:1.

Submitted by LindaG on September 2, 2006 - 9:18pm.

I just found something that discusses that very thing. (The following is from the "Peak Oil Primer" found at the Energy Bulletin.)

To evaluate other energy sources it helps to understand the concepts of Net Energy, or the Energy Returned on Energy Invested ratio (ERoEI). One of the reasons our economies have grown so abundant so quickly over the last few generations is precisely because oil has had an unprecedently high ERoEI ratio. In the early days of oil, for every barrel of oil used for exploration and drilling, up to 100 barrels of oil were found.

Peaking of World Oil Production: Impacts, Mitigation and Risk Management

The peaking of world oil production presents the U.S. and the world with an unprecedented risk management problem. As peaking is approached, liquid fuel prices and price volatility will increase dramatically, and, without timely mitigation, the economic, social, and political costs will be unprecedented.

Carbon dioxide is part of nearly everything humans do. It comes out of the tailpipes of our cars, the stacks from most of our power plants and the nostrils on the tail end of every breath we take. From a climate change perspective, of course, all this CO2 is a problem, given the greenhouse property of the gas. A variety of solutions have been proposed, including burying the stuff deep below the earth or sea or switching to fuels that do not lead to its emission, but now a scientist from Italy has offered another possibility: turn it back into fuel.

Chemist Gabriele Centi of the University of Messina in Italy uses solar energy gathered by a titanium dioxide film to ionize CO2 in its liquid form. Mixing this ionized liquid carbon dioxide with water, chemists can create longer carbon chains, much like photosynthesis in plants. In current tests the process can create some natural gas and methanol, but the number and type of carbon chains cannot be controlled.                         
 
Centi's team decided to try to use carbon dioxide in its natural form: gas. In a device much like a fuel cell, known as a photoelectrocatalytic reactor, the researchers tested several potential catalysts, ranging from copper to carbon nanotubes. In each case, the process turned CO2 into more complex carbon molecules. Most intriguingly, depending on the catalyst involved, the researchers could create hydrocarbons with as many as nine carbon atoms--the kinds of useful fuels produced by industry using the so-called Fischer-Tropsch reaction--and with some control over the amount made. Further, by placing iron molecules within the carbon nanotubes, the process could be made even more efficient, though not as much as using expensive platinum or palladium. "It is a long time to practical applications," Centi says. But he notes it might prove useful on a manned mission to Mars, which cannot easily carry enough fuel for its return, to be able to make it on the Red Planet itself. Centi presented his new gas phase research on September 13 at the American Chemical Society meeting in San Francisco. --David Biello

Cleantech Smackdown: Algae vs. Soybeans

http://www.redherring.com/Article.aspx?a=20129&hed=Cleantech+Smackdown%3a+Algae+vs.+Soybeans

December 7, 2006

By Jennifer Kho While some see algae as the ideal source for biofuels, industry watchers at ThinkEquity’s Greentech Summit in San Francisco on Thursday said the technology is likely to be years away. “Algae, as a biodiesel feedstock, is further out than cellulosic ethanol,” said Martin Tobias, CEO of biodiesel company Imperium Renewables, referring to ethanol from materials like wood chips, switchgrass, and corn stover.  Algae simply aren’t available in large-enough quantities right now, he said. “We’re opening a 100-million-gallon facility in June, and there won’t be 100 million gallons of algae available next year,” he said. “It’s not about whether algae can produce oil, but about whether it can meet a standard quantity needed for fuel. It’s going to take longer than anyone wants to say at an investor’s conference. Whereas with farming, we can make a significant replacement of fuel now, with what we have.”  Many consider algae an attractive alternative to current biofuel feedstocks—such as corn, soybeans, and palm—because of its high lipid density, which means it could theoretically produce far more oil per acre and could potentially reduce the cost of biofuels. Mr. Tobias said algae could theoretically produce 10,000 gallons of oil per acre. That compares with the current highest-oil-yielding crop, palm, which yields 680 gallons per acre, he said. Holy GrailBecause algae could be grown in a factory, instead of on farmland, it could also help counter the “food vs. fuel” argument about biofuels.  With current technology, the U.S. Energy Information Administration estimates that 20 percent of the land in Europe and the United States would have to be used to grow crops just for energy in order to replace 5 percent of gasoline and diesel with biofuels. And many—including Luca Zullo, director of bioenergy at Cargill, who attended the panel—worry that using farmland for fuel crops could jeopardize the food supply. “It’s the 500-pound gorilla of the biofuel industry,” he said, referring to the food vs. fuel problem. “It’s a serious moral question, a serious national security question. I think we fundamentally need to look for feedstocks that can help with this issue, feedstocks that use underutilized water and underutilized land.” Also, algae could be better for the environment because algae-growing takes about a third of the water as it takes to grow soybeans, said Lissa Morgenthaler-Jones, CEO of LiveFuels, a company developing “biocrude” from algae that, like petroleum-based crude oil, could be turned into fuels. “In some ways, people think of algae as the Holy Grail of the feedstock issue,” said Ira Ehrenpreis, a general partner at the cleantech venture capital firm Technology Partners. “But there are shorter-term prospects than algae. Algae represents an opportunity that may occur over the longer horizon.” Fraught with DifficultyThe panel made it clear that the path leading algae to the mass biofuels market is fraught with difficulty. “It’s very difficult to grow algae,” said Cary Bullock, CEO of Greenfuel Technologies, a startup developing a technology to turn smokestack emissions into ethanol and biodiesel, at the “Algae as a Biofuel Feedstock” panel. Greenfuel is growing algae in open ponds, which has lower capital cost than other methods but does have significant issues to overcome.  Mr. Bullock described the process: First, you need a distributed light source to get light past the top layer of algae and deeper into the ponds. One you solve that problem, you discover that the algae runs out of food. To increase the food supply, you have to make significant changes to the nursery system. And once you’ve done that, you have to manage heat. “Two of those problems would be difficult, but all four together are quite a problem,” he said, adding that Greenfuel expects to solve the problems with solutions it’s developing. Also, the whole thing must be done at $42 a gallon to allow biofuels to compete with gasoline and diesel fuel, Ms. Morgenthaler-Jones said. “After that, you’ve got nowhere to run and nowhere to hide,” she said.  Mr. Bullock said he wouldn’t comment on Greenfuel’s current costs, but said the company is targeting costs of $100 to $200 per ton of algae “over the longer term.” Aside from capital costs, reliability has been an issue, said Doug Cameros, the chief scientific officer for Khosla Ventures and the moderator of the “Algae as a Biofuel Feedstock” panel Thursday. Also, while farm crops already have systems in place to distribute and sell them, and have additional value in byproducts other than oil, algae doesn’t have a ready-made market, Mr. Tobias said.  “The challenge for algae is going to be, what do you do with the parts that are not oil?” he said. “How do you expel it, what do you do with the leftover stuff, what is the value of the oil versus the value of the other stuff? You have to look at the total value you get out of the product, not just the oil.”  Worth PursuingDespite the problems, a number of startups—and their investors—think the potential for algae is worth the risk.  There’s no doubt a better feedstock is needed, and algae is worth pursuing, Mr. Tobias said. “Eighty percent of the cost of making biodiesel is the cost of the oil going in,” he said. “We need that to go down.” He said he has an order waiting for the first algae supplier who can sell him enough quantity to feed the 100-million-gallon plant Imperium is building. “I’d be happy to be a customer,” he said. But while he expects investors will back the idea, Mr. Tobias said he wouldn’t invest in algae himself. “It’s not going to happen in my lifetime, which I define as three years,” he said. “It’s not that I expect to die in three years, but that’s the farthest out I can see.”
