Peak Oil Matters

A fresh perspective on the concept of peak oil and the challenges we face

Tag: oil shale

In a recent post (here), I discussed the unfortunate practice by Peak Oil dissenters of cherry-picking facts to suit their skewed perspectives on the reality of oil production, conveniently neglecting to provide readers with the relevant background information needed to properly understand the issue at hand. An equally discouraging exercise is their use of vague, impressive-sounding but ultimately meaningless words and phrases to try and bolster their side of the argument. Perhaps they count on apathy or ignorance on the part of their readers, but regardless of the rationale, it does little to help. (Why do they insist on doing this? The Boston Globe published an interesting piece on Sunday that may provide answers.)

A recent and particularly egregious example can be found here. Feel free to read this glowing exhortation about the bazillion years of oil we have at our beck and call via oil shale. The author of that snarky piece excels at long division, but note the complete failure to mention even a single fact as to what is actually required to produce the oil shale this writer so ardently touted. Why let the truth get in the way of nonsense? (Hard to be kind to this narrow-minded wing-nuttery, so this is the best I can do.)

Just for the heck of it, take a peek at these prior posts (here and here) offering information about what is involved in mining oil shale and how utterly ineffectual efforts have been for most of the past few decades.

Facts are indeed an annoying intrusion into the puzzling reality of some.

This past weekend I came across yet another article where the full range of information was conveniently omitted. When you write a piece like this offering up at best fuzzy details and are hoping/praying/counting on your readership being uninformed and thus reliant on whatever details you do or do not provide, I can only assume there is some benefit to be derived. Engaging in open and honest debate, however, would not appear to be on that list. If all the facts aren’t on the table, then what does that suggest about the argument being made?

“Resources in the ground are clearly abundant. Canadian Association of Petroleum Producers Vice President Greg Stringham, pointing to the 175 billion barrels recoverable from the Canadian oil sands, says, ‘It won’t be a lack of resources that causes a shift away from oil. There’s lots of oil.’ The United States Geological Survey recently updated their estimates for recoverable oil from Venezuela’s Orinoco Belt to 513 billion bbl. Compare this to BP’s estimate of some 1200 billion bbl of global conventional oil reserves. Some shale formations, such as the US’s Bakken and Eagle Ford, contain substantial amounts of oil and natural gas liquids too, a form of unconventional oil which has emerged from nowhere in the past few years.

“Traditional onshore light crude, though often inaccessible to the international oil companies, remains plentiful too.”

(My bold italics were added for emphasis)

I’ve already acknowledged, as have many other Peak Oil advocates, that there are indeed hundreds of billions of barrels of oil in the ground. We’re not running out of oil. Those are not facts in dispute, unless you are arguing whose estimates are correct. But as is frustratingly obvious yet again, this Oil Council article fails to make mention of a single fact about the difficulties, costs, environmental degradation, time factors, or energy expenditures incurred in producing these resources. Uninformed readers are left with the impression that a shovel and sturdy straw are pretty much all that’s needed to extract this “plentiful”, “clearly abundant” oil from underground. (How many barrels are in a “plentiful”?)

Hello?!

The simple truth is that there is a big difference between what’s in the ground and what’s feasible or even possible to get out of the ground (or in deep water). So just tossing out large numbers or unquantifiable phrases like “substantial amounts” without a corresponding explanation that these tidbits don’t necessarily mean that we can actually extract or produce them is misleading. I always find it very difficult to understand the purpose or intent of such efforts, and remain dismayed that the fear of engaging in honest debate trumps the importance and necessity of having that honest discussion, regardless of outcome. Aren’t we all better served when we can deal with full truths rather half-ones, painful though it may be? What is gained otherwise?

If facts are wrong—mine included—then they’re wrong, and we are all better off knowing that and moving forward with better information. I wish it could be that simple….

“Kuwait and Abu Dhabi recently updated ambitious plans for production gains.”

And…? They can “update” their “ambitious plans” until pigs fly, but what does any of that prove? That’s a solution?

Likewise, cornucopian arguments proffered by this article about the “technical potential” of Iraq’s oil fields are pointless! What’s involved in realizing this “technical potential”? How many years? How much money? What are the complex political factors to be addressed? What other resources will be needed? How much energy will have to be invested in order to extract all this potential? When all is said and done, how much production can realistically be expected?

(An aside: Andrew McKillop, writing on Sunday about the Gulf of Mexico oil spill, noted (here) that BP’s Macondo field, thought to contain somewhere in the vicinity of 300 million barrels of oil—three or four days’ worth, by the way—could realistically have been expected to extract no more than 50 million barrels, and over 15 years or more. These are the types of facts we need to be dealing with and explaining to others instead of pretending that all will be well because we still have “lots” of oil left.)

And touting the 21 billion barrels of oil Iran has produced in the past dozen years sounds terrific up until the moment you realize that’s about 7 months’ worth of supply. Probably want to hold off rushing out the door to buy that soon-to-be-extinct Hummer you’ve always dreamed of….

“Kazakhstan’s long-delayed Kashagan field will finally come onstream around 2013 and yield more than 1 million bbl per day.”

Pulling out my trusty calculator, I conclude that 1 million barrels per day times 365 days in a year means that the Kashagan field will yield about 365 million barrels per year, or … Gasp! almost five day’s worth of oil! Hallelujah! Our prayers have at last been answered! Wow, that was close! I thought we all might actually have to start giving up things and changing lifestyles, but oh, no! Just a handful of these producing oil fields could get us enough oil to last until … uh, uh, a few weeks.

These resources and finds are surely better than a stick in the eye, but really? This is what’s being touted as the answer to Peak Oil’s discouraging message and worrisome impact? Oil production is on the decline, and these feverish efforts to paint a rosy picture help no one prepare for and plan the changes societies will need to implement. Whatever transitions away from fossil fuels we can collectively fashion will carry their own hardships. Let’s not make it worse by avoidance.

I understand that no one really wants to have to deal with the problems and challenges of declining oil production. Sure as hell I don’t! There is nothing even remotely enjoyable to contemplate about the onset of Peak Oil and its impact on my own pleasant, suburban multi-car, two-home lifestyle. Millions and millions of others who understand the implications and consequences will be/are just as dismayed for their own reasons—selfish or otherwise.

Making do with less is not anyone’s idea of progress or pursuit of the great American Dream. I understand the instinct to avoid, deny, or just pretend otherwise. The problem is that those strategies are not only not going to work, they will ultimately make things worse for all of us. They may serve some weirdly narcissistic, narrow-minded short term interests, but we are all in this together—deniers, too. Their magical thinking won’t prevent Peak Oil from impacting their lifestyles and businesses. Unless you have managed to carve out a lifestyle entirely independent of fossil fuels, either by avoiding personal use of it or avoiding goods and services that require it, Peak Oil is going to affect you, and perhaps quite dramatically.

Let’s not wait until we’re all in full-fledged panic mode over what is happening when supply can no longer match demand. It’s not that far away … and much too soon for us to avoid all the nasty consequences Peak Oil is going to impose on us. Disingenuous “information” is thus not at all helpful unless perpetuating a lack of understanding and awareness are the objectives.

If this deliberate obfuscation of facts and the true import of Peak Oil’s impact is the best that the deniers can offer, doesn’t it contain at least a seed of suggestion that perhaps we all ought to be thinking a bit more seriously about what needs to be done? We’re years behind as it is. As painful as it will be to confront the possibilities of having to make do with less for many years to come, having some say in how we collectively prepare for and deal with the impact of declining oil production seems a better long-term option.

Relying on these half-baked missives of optimism is an exercise in foolishness none of us can afford

The potential of more than 2.5 trillion barrels of synthetic crude oil from oil shale is nothing short of fantastic! (Nearly two-thirds of that amount is located principally in the Bakken Formation of North Dakota, Montana and Saskatchewan; and the larger Green River Formation of Colorado, Wyoming and Utah.) With annual worldwide oil consumption of approximately 30 billion barrels of oil, it would seem that oil shale’s astonishing numbers drive yet another nail in the coffin of Peak Oil theory.

A couple of trillion barrels of oil from shale formations will hold us in good stead for more than a few lifetimes! (In a report issued several years ago, the RAND Corporation estimated that the Green River Formation alone could provide a quarter of this country’s current oil needs for 400 years! Amazing! [1]) It’s every bit as awe-inspiring a number as are the potential tar sands resources in Alberta.

Of course, there are two sides to every story, and like the tar sands of Alberta, there’s an enormous gap between what may rest beneath the ground and what we’ll be able to extract, refine, and eventually use over the course of many, many decades. Like its unconventional oil companion to the north, oil shale is not likely to be the solution to our energy concerns in the next several decades. If it ever is, it may be too late in any event.

Geologists and the United States Geological Survey estimate there are approximately 4.3 billion barrels of technologically recoverable oil in the Bakken region. We may possess the capabilities of extracting that much oil, but the costs going in and the consequences of attempting to extract and produce oil from shale are different matters entirely, so what may be “technologically recoverable” is by no means the same as “economically feasible.” And let’s also take note that 4.3 billion barrels of oil is about 7 or 8 months’ worth of oil consumption here in America, and the best hope is that all of that would be extracted over the course of no more than twenty years. Not particularly impressive.

The other formations appear to hold not much more promise, although the more optimistic estimates suggest we might see as much as 130 billion barrels of oil from them … eventually. (One expert directly involved with Shell Oil’s production efforts suggested back in 2005 that by 2030 we might see 5 million barrels per day from the formations out West. [2] Five million bpd doesn’t mean all that much now; it will mean much less a couple of decades into the future.)

Oil shale is, as acclaimed energy expert Chris Nelder has stated: “the oil of the future … and it always will be.”

The truth is that after nearly fifty years of attempts to develop oil shale into a satisfactory oil substitute, only a few hundred million barrels of oil have been produced, if that. In other words, we’ve probably managed to supply about a week’s worth of worldwide oil demand as a result of all that effort and money over nearly half a century. Trillions of barrels of oil! stops sounding so impressive when reality intrudes.

A recent and significant increase in production (see a detailed explanation here: http://www.theoildrum.com/node/5928#moreThe Bakken Shale – Has it Moved the Oil Needle? by Gail the Actuary, November 2, 2009) does not change the basic fact that no company has yet made the full-scale commercial production of oil shale economically feasible—with no guarantees that we’ll ever see that outcome. The research and testing of commercial capabilities are not adequate to the task after decades of effort, nor do we have in place the proper facilities that would be needed to handle production demands. They won’t pop out of the ground fully-formed any time soon.

Best estimates are that establishing those essential commercial components is at least another decade away. By then we’ll be well on our way to decreasing supply trying to match increasing demand. That’s bad math.

Part of the reason is that like tar sands, oil shale is not easily extracted. Oil shale is not oil. It’s kerogen, a solid, not-yet-fully matured version of the fossil fuel. More specifically, it’s the organic matter within the oil shale, and in order for the oil to flow free of the shale and be pumped to the surface, it must be heated to more than 700 degrees for a couple of years (while surrounded by a three-foot wall of ice)! This is the “in situ” procedure. The other primary means of obtaining kerogen (usually buried thousands of feet below ground, by the way) is the “retorting” procedure: mining the oil shale and then heating the kerogen above-ground.

Either option represents the investment of a LOT of energy. It’s also important to appreciate that oil derived from kerogen requires further refining before it can be used for transportation purposes … more effort and expense after extraction.

And I won’t touch on the significant amounts of water required to help extract oil shale (and in regions of this country where water is a limited resource to begin with) nor am I discussing in this post the environmental degradation and pollution that results from mining this resource. I also omit any discussion about the impact of such massive undertakings on the local communities involved. I can omit discussion here, but we cannot ignore those considerations.

These pesky little details seem to get overlooked by those who dispute Peak Oil’s imminent approach.

At what point do we decide that the tens and hundreds of billions of dollars we seemingly have at the ready to invest in oil-related energy exploration and production ought to be devoted to resources not quite so limiting? Like the oil from tar sands, oil from oil shale is not anywhere near as productive or efficient an energy source as conventional crude oil … not even close, actually.

We’re just postponing the inevitable, and it seems we should be seriously considering alternatives (not that they are a panacea, either, since we need a lot of oil to research, extract, produce, process, and transport almost every other form of energy). They will at the very least represent a much better long-term solution than oil, shale, and tar. How difficult do we want to make the transition away from oil-based energy?

We have some choices to consider….

Hello again!

In my last post, I took a brief look at some of the facts suggesting that we are indeed at or very near the point when our planet’s maximum rate of oil production has been reached.

Today, I’ll point out some of the more popular arguments here in the U.S. disputing Peak Oil. As I’ll do with the information from my prior post, I’ll likewise expand my examination of this material in future discussions.

Four popular arguments against Peak Oil are discussed below (although they are not necessarily the primary debating points). In no particular order, these refutations are as follows:

  • there are billions if not trillions of barrels of “unconventional” oil in the shale deposits of the western United States
  • there are comparable amounts of unconventional oil in western Canada (the oil or “tar” sands of Alberta), and thus the  combination of these oil resources will supply us with all the oil we need for hundreds of years
  • the Arctic region/Arctic National Wildlife Refuge (ANWR)/offshore areas here in the U.S hold billions of barrels of oil
  • technology will be developed to boost oil production in existing fields or aid in the discovery of as-yet undiscovered fields

While reminding you that I lack the professional expertise of an engineer or geologist, I nonetheless do not challenge the range of estimated oil resources touted in the Alberta oil sands and America’s oil shale deposits.

Where I take issue is that the related facts and details about production and extraction of shale and sand are all too often conveniently omitted when these massive resources are hailed as the solution to any oil supply problems we might face. Just throwing out the phrase “trillions of barrels” is at best disingenuous. (Despite other arguments suggesting similar amounts of conventional oil reserves, most experts state with about 90% certainty that there are about 1.2 trillion barrels of crude oil reserves. [1]) Resources are not the same as reserves. There are no guarantees that “resources” can ever be successfully produced.

In more than thirty years of attempted production, about 110 million barrels of oil have been produced from oil shale (principally in the Bakken region of Montana and North Dakota). [2] That’s not per year. That’s a thirty-plus year total. (Our nation uses somewhere around 20 million barrels per day; worldwide the usage is approximately 85 million barrels per day). No one has yet managed a commercially viable method of production. One hundred and ten million barrels doesn’t sound quite that impressive when you stack that up against daily usage.

Most experts, even the most optimistic ones, suggest that it will be decades before oil production from oil shale reaches as much as 200,000 barrels per day. With demand expected to rise to over 100 million barrels per day in the next two decades (ignoring depletion rates in existing fields entirely, which the International Energy Association’s World Energy Outlook 2008 estimated at 6.7% a year and rising [3]), that’s not much of a dent.

Most underdeveloped nations aren’t especially inclined to wait a few more decades to improve their lot. Certainly China and India aren’t idling! Demand will increase, supplies will become more strained, and problems will ensue.

Similarly, most experts have pegged maximum lifetime production from the Alberta tar sands at a total of less than two hundred billion barrels. Not an insignificant amount to be sure, but it will take many decades to extract it all. Even the most optimistic supporters of oil sand production don’t expect production rates of more than a couple of million barrels per day—and that is many, many years down the road.

That won’t help much. It’s even less significant when you factor in the environmental degradation wrought by oil sands mining (as will be discussed in an upcoming post). The amounts of water and natural gas required in the process of extracting oil from the sands will cause its own set of problems in the not-too-distant future. Soil and water contamination issues are also prevalent.

As for the Arctic and offshore areas, there may indeed be “significant” finds, but … hello! Exactly how easily and efficiently is that going to be achieved? How many hundreds of billions of dollars and how many years and how much effort will it take if those areas do turn out to be a bit of a boon once again?

There are reportedly about 10.5 billion barrels of oil available in the ANWR, and tens of billions of barrels offshore. Natural topography and climate alone mean that herculean efforts would be needed … and none of that is free! Experts tell us that offshore fields (ignoring the immense difficulties of extraction/production) decline faster and sooner than fields on land.

If we have to go to those lengths and expenses to locate and produce oil, what does that tell you? No expertise required … just a bit of common sense.

Let’s not ignore the fact that as oil exploration becomes more challenging, expensive, and time-consuming, the energy required to locate and extract the oil increases as well, and thus the net energy gained is much less. Crude oil is a remarkably productive source of energy, and for all the talk about oil from the sands and shale, the return on those sources of energy is minimal in comparison. We’ll need a lot more of those resources to produce the same amount of work as crude oil.

As for technology, if one pays attention to the language used, there’s a lot of “potentially’s” and “maybe’s” and “could’s” and “might’s” liberally sprinkled through the optimistic declarations that peak oil is not an issue. My own favorite is “future discoveries of ‘superfields’ of conventional oil reservoirs could boost world production.” [4] Uh, well … ah, yes, I guess that’s true. Not exactly a solution we can count on, though. Future discoveries that indicate we can get oil from mattresses or hats could also boost world production, but….Need I say more?

The notion that higher gas prices will spur development of new technologies conveniently ignores the fact that there are not oodles of new technologies hiding in laboratory closets just waiting to be loosed on planet Earth next week. I have no doubt that technology will continue to improve the quality of our lives, but technology developed and perfected for commercial usage requires time, energy, effort, and money—among other things. What might prove economically or practically feasible 5, 10, 15, or 50 years from now isn’t of much help … now!

There are legitimate and not-so-legitimate arguments for and against peak oil, and like most complicated issues in this day and age, trying to figure out what is right and what is rightfully ignored is no easy task. I’ll do my best in future posts to help you sort through it all and assist you in coming to a better understanding of Peak Oil and its implications.
