    About this ebook

    In two earlier books, Hubbert's Peak (2001) and Beyond Oil (2005), the geologist Kenneth S. Deffeyes laid out his rationale for concluding that world oil production would continue to follow a bell-shaped curve, with the smoothed-out peak somewhere in the middle of the first decade of this millennium—in keeping with the projections of his former colleague, the pioneering petroleum geologist M. King Hubbert.

    Deffeyes sees no reason to deviate from that prediction, despite the ensuing global recession and the extreme volatility in oil prices associated with it. In his view, the continued depletion of existing oil fields, compounded by shortsighted cutbacks in many exploration-and-development projects, virtually assures that the mid-decade peak in global oil production will never be surpassed.

    In When Oil Peaked, he revisits his original forecasts, examines the arguments that were made both for and against them, adds some new supporting material to his overall case, and applies the same mode of analysis to a number of other finite gifts from the Earth: mineral resources that may be also in shorter supply than "flat-Earth" prognosticators would have us believe.

      Isn't there a type of sedimentary rock, a conglomerate, where good sized chunks of all sorts of minerals get smashed together in a rather fragile matrix? That's what this book is. Lots of insights pulled out of the author's long experience in geology and mineral extraction. But there is not much cohesiveness to the whole.

      The general thrust is: given that petroleum production peaked in 2005, what now? The book was published in 2010. I'm not sure the 2005 peak has held, not that we have surpassed it by much or that there is much prospect of doing so in the future.

      Deffeyes takes a grand engineering perspective here. How do we manage the system? There are big problems with this. Planet scale engineering does not permit failure-prone tinkering. Of course, failure-prone tinkering is exactly what we are facing. But Deffeyes doesn't really look at that angle. For him it seems to be like when your car breaks down on the side of the road. Just patch some solution together to get to the next proper garage. Yeah at the very end he mentions that the human population is probably already above the sustainable carrying capacity of the planet. That's a detail! But he just tosses it in at the end.

      Well, he's an old guy with lots of bits and pieces. It's a bit like a craftsman retiring and passing along their shop to a new owner. Lots of wisdom and experience packed into all the tools and materials lying about. But the working craftsman created a context where all those pieces made any kind of sense. For the new owner, it's really just that conglomerate rock that crumbles as you pick it up. The pieces are nice bits of mineral, but now it's up to us to fit them together in a way that serves our purposes.

      Deffeyes takes some credit for the fracking boom in e.g. Pennsylvania. I don't think he mentioned North Dakota. How quickly these things boom and bust! But he doesn't address the risks and costs of fracking. He is also rather dismissive of the risk of climate change. OK, the geological record is filled with changing climate. It's funny because he proposes geo-engineering - some massive salination-balancing canals across Panama - so we see than humans can intentionally have a significant effect on the climate - doesn't that imply that CO2 emissions could have a significant effect, even if unintentional?

      There is a kind of inconsistency here... he never quite says "So what if humans go extinct, species go extinct all the time!" but actually his geological perspective is vaster yet than that. On the other hand, he's got these dramatic proposals for avoiding any real adjustment to our way of life, contra those crazy climate change folks.

      It's a fun conglomerate to wander through but I didn't find any coherent message. I don't think that was the intent. Thanks, Professor Deffeyes, for passing along your fine craftsman shop full of mineral delights, for we of the next generation to put to good use! Enjoy your retirement!

    When Oil Peaked - Kenneth S. Deffeyes

    Preface

    There is an ongoing debate between peak-oil people, those who think that we have already found most of the world’s oil, and their opponents, who insist that tweaking the economic system will enable us to find lots of additional oil. Colin Campbell, one of the peak-oil leaders, has repeatedly referred to Michael Lynch as that flat-earth economist. For a long time, I thought that it was just an insult. (Lynch never claimed to be an economist.) Finally, I understood. On an extended Earth you can have an infinite amount of oil. On a round earth, there are limits.

    Most of the peak-oil people credit the American geologist M. King Hubbert (1903–1989) for making the earliest solid analysis of the problem. His followers are sometimes called Hubbertians. The opponents are cornucopians, named for the traditional horn of plenty. At the moment, the intellectual debate remains unsettled. Out in the real world, however, the story is unfolding; the contest is being decided in the marketplace. I’ve been a Hubbertian since the late 1950s. I’m a geologist, with no professional expertise in economics or politics. My arguments come largely from the viewpoint of earth science. The purpose of this book is to update the peak-oil debate and then to extend the coverage to include other resources. Are we next going to see peak copper or peak phosphate?

    In my first oil book, Hubbert’s Peak (2001), I followed Hubbert’s methods and predicted that world oil production would peak in the year 2005. Currently, the U.S. Energy Information Agency shows 2005 as the peak year, with 2008 in second place. Blow the trumpets! Hubbert’s method actually works!

    The Round Earth

    On a spherical Earth, there is a fixed surface area that we can explore for oil. World oil production increased rapidly from the first wells, around 1859, up to the year 2005. From 2005 onward, oil production has shown no growth. This, of course, is the story that is unfolding before our eyes. Will delays and cancellations brought on by the 2010 BP blowout in the Gulf of Mexico leave 2005 as the peak year? Stay tuned, this is your future.

    Obviously, we have been handed a major financial crisis. Initially, Barack Obama’s staff was heavily focused on thawing out the financial system. I once had a computer with a clickable item called last good menu. It was a way to go back to the time before the computer crashed. The White House staff seems to be looking for a reset button to return us to 2003. Of course, it won’t work. Everybody won’t get their jobs back, or their houses; world oil production will not increase. The invisible hand of economics is now clenched into an invisible fist, pounding the world economy down to fit the resource base.

    To his credit, President Obama has stated that the energy crisis and health costs are major important items. Crude oil prices had already doubled before the Bear Stearns collapse in March 2008. The Dow Jones Industrial Average peaked even earlier, on October 5, 2007. It seems obvious to me that the oil problem is the disease and the financial recession is a symptom. Oil production ceased growing in 2005, as I had predicted four years earlier. In May 2005, oil was priced at 44 dollars per barrel, and in July 2008, crude oil reached 147 dollars per barrel. Oil production in July 2008 was 0.2 percent higher than in May 2005. That wasn’t exactly what we learned in Econ 101: Tripling the price brought out only a trivial amount of additional oil. The chant of Drill, baby, drill at the 2008 Republican National Convention had a hollow ring to it.

    Economists and geologists have a long-standing disagreement about the availability of resources. I worry that the emphasis on economic growth stems from their operating the U.S. government as an enormous Ponzi scheme. I’m not alone in that concern. I looked up Social Security ponzi on Google and got 310,000 hits.

    It’s just a geological accident that oil caused the problem. It might have been phosphate instead. OPEC would have been the Organization of Phosphate Exporting Countries, with exports from Morocco as number one and the United States as number two. A phosphate crisis would have been enormously more disruptive than too little oil.

    Although I grew up in the oil fields, I barely recognize the oil industry as it is today. When I was young, the major oil companies (the Seven Sisters) dominated exploration, production, refining, and marketing. The majors generated wealth by finding and owning giant oil fields. Today, national oil companies dominate most of the oil-productive areas. Whereas the major oil companies used to operate large corporate research laboratories, innovation now comes largely from service companies like Schlumberger and Halliburton. The Seven Sisters are still around, although some of them have been absorbed through mergers. In a sense, each major now consists of skilled professionals with a merchant bank attached. Will work for a small share of the oil.

    Crude-oil prices (uncorrected for inflation) and the fall of the American economy. The Bear Stearns collapse is usually regarded as the first major incident at the beginning of the meltdown. The price drop in early 2009 did not magically transport us back to the year 2004. (© Steve Deffeyes)

    Although M. King Hubbert is regarded as the patron saint of the peak-oil crowd, his methodology and his conclusions are still the subject of criticism and skepticism. It’s important not to claim that Hubbert is infallible; I point out several flaws in his work in this book. Of the many Hubbert critics, Richard Nehring published one of the most detailed analyses, and his critique is backed by data. I explain in chapter 2 how Nehring’s analysis runs afoul over small-sample statistics.

    An original contribution in chapter 1 of this book is an attempt to supplement the logistic bell-shaped curve (the one that Hubbert used) with a similar justification for the Gaussian bell-shaped curve. The Gaussian curve has a wider top and narrower tails. An evaluation of several different bell-shaped curves, using several data sets and several fitting methods, was done in 2007 as a Princeton senior thesis by Benjamin Steiner. Steiner’s conclusion was that all combinations of math, data, and methodology gave essentially the same results for the next ten years.

    Oil prices are a subject of never-ending interest. Chapter 4 contains a graph of the total annual price paid for crude oil as a percentage of the gross domestic product. Oil costs during the 1990s were less than 1 percent of GDP; those years brought us the SUV gas guzzler. Oil costs exceeded 4 percent of GDP in 1981 and again in 2008. Both of those price spikes caused extensive damage to the U.S. economy.

    Oil prices have a selective impact on various countries. In particular, Iran and Venezuela need a price above seventy dollars per barrel to support their national adventures. In most of the world, low oil prices (and the possibility of even lower prices) have forced the postponement or cancellation of a substantial number of oil projects.

    There are some bits of good news from the oil patch. The question is whether they are just a small amount of good news embedded in a larger mass of bad news. The bad news is that the supergiant oil fields that supply much of our oil are getting older and declining in production. For oil, I suspect that the good news is not good enough; it is not a game changer. For natural gas, the good news might be the opening of an era of increased supply.

    The best oil news comes from offshore Brazil. Petrobras, the Brazilian national oil company, has made a string of remarkable new discoveries of light high-grade oil, possibly the biggest discoveries since 1976. However, the wells are very deep and very expensive to drill and to operate. If the price of oil is too low, the deepwater Brazilian production will be zero. In a neatly ordered economic world, the crude-oil price would settle just above the level that makes the Brazilian offshore fields viable. Unfortunately, at their best, the Brazilian fields will not offset the production declines elsewhere in the world.

    For natural gas, there is a new ball game. We can state it in a pithy seven-word sentence: Mature oil source rocks will yield gas (this mantra is explained further in chapter 9). Suddenly, whole new provinces of natural-gas fields have become available. On an equal-energy basis, about 6,000 cubic feet of gas equal a barrel of oil. Because natural gas is a cleaner-burning fuel than oil, we would expect natural gas to command a premium price. Not so. When oil is selling for $68 per barrel, dividing the oil price by six gives an energy-equivalent natural-gas price of $11.30 per 1,000 cubic feet. If natural gas is actually selling for $3.60, that means it is available for one-third of the energy-equivalent price of oil. My interpretation is that today’s low natural-gas price results from the (real or imagined) extent of potentially large new gas supplies.

    On a time scale somewhere between one hundred and three hundred years, our civilization has to come around to sustainable and renewable resources. Most energy will be, directly or indirectly, solar. (Wind farms, hydroelectric dams, and biofuels are indirect forms of solar energy.) We don’t have to go solar next week, but we don’t want to end up in any dead ends on the way to a solar future. In particular, even the enhanced natural-gas supply might not carry us all the way over to the solar Promised Land.

    Among the available energy sources already identified are uranium and coal. Both are politically unpopular. However, as we run out of alternatives we may have little choice. For uranium, acceptably safe reactors have been engineered and the radioactive waste disposal problem was already solved in 1955, as discussed in chapter 7. Also in chapter 7 is a generalization of the uranium roll-front deposits to a variety of other metals.

    Coal was, of course, the fuel that originally powered the Industrial Revolution. Several new evaluations of the world coal supply have appeared recently. Two centuries of experience led to new methods for finding and extracting coal. The problem is exploiting the coal without fouling Earth’s atmosphere. An updated version of the 1870s technology for coal gasification may offer an acceptable way of exploiting coal (chapter
