Is peak oil a myth?

An op-ed piece by Michael Lynch in the New York Times suggests that "peak oil theory" is just a myth [LINK]. Really what he's saying is that it is a crazy left-wing conspiracy theory. I wanted to just post some reaction to his op-ed, calling some of his arguments into question. I'm not going to claim he's wrong, just that his arguments are far from persuasive. First, let's also have some disclosure, Michael Lynch is President and Director of Global Petroleum Service, part of Strategic Energy & Economic Research Inc [LINK]. This is a consulting firm, and I have a sneaking suspicion that a lot of their clients are oil companies. He's also been associated with other energy policy organizations as well as MIT. I'm not saying he is not credible, I'm sure he's an expert, I'm just saying Lynch is probably as biased as the people he is criticizing.

Lynch dismisses the statement that the "easy oil is gone." This is a common point made by people concerned with peak oil, as Lynch points out. The idea is that 100 years ago, there were oil fields that literally had oil coming out of the surface. Remember the Beverly Hillbillies? Now there aren't such high-pressure fields. Instead of accepting that as true, Lynch says the argument is "vague and irrelevant." He then says that Persian oil drillers 100 years ago wouldn't think that oil was "easy." This is a false analogy. Nobody is saying that the labor of extracting oil was ever easy. The point is about how much energy has to be spent to extract a given amount of oil, which then produces a given amount of energy. It's not easy to quantify, but as I understand the state of oil today, more energy is used to extract oil per unit energy now than it was, say, in the 1950s.

A point made just after the one above revisits the oil crises in 1973 and 1979. Lynch points to predictions from "experts" saying prices would just keep going up. Then they didn't go up. This is supposed to be part of Lynch's op-ed about arguments of political instability playing a part in oil production; he's saying that political instability is nothing new. In my reading of his article, I find that this whole section is really a straw-man argument. He brings it up because, "When their shaky claims on geology are exposed, the peak-oil advocates tend to argue that today’s geopolitical instability needs to be taken into consideration." So he sets up an argument that is not about peak oil just to shoot it down. The question of peak oil is essentially one of geology and technology; geopolitics certainly plays a role in oil production (well, maybe not according to Lynch), but it isn't part of the peak oil theory except that if production ceases in a region, then the peak would be pushed back in time.

Finally, Lynch ends with this:
In the end, perhaps the most misleading claim of the peak-oil advocates is that the earth was endowed with only 2 trillion barrels of “recoverable” oil. Actually, the consensus among geologists is that there are some 10 trillion barrels out there. A century ago, only 10 percent of it was considered recoverable, but improvements in technology should allow us to recover some 35 percent — another 2.5 trillion barrels — in an economically viable way. And this doesn’t even include such potential sources as tar sands, which in time we may be able to efficiently tap.

Well, there's a bit of an appeal to authority here, but I'm not going to claim that there's a real logical fallacy. This might just be a case of presenting (without evidence) a number that differs from the estimates I've seen before. Because there are no sources or evidence presented, it is impossible for the reader to know if this point is true or not. My guess is that there are some large error-bars on that 10 trillion barrel number, and this value is probably at the high end of them. I would hazard to guess that the 2 trillion barrel number is too low (and I have heard that number before), but that 10 trillion barrels is a pretty high estimate. The recoverable part of whatever the true number is the real question. The truth is, though, that at some point the extraction of oil becomes cost ineffective compared to other energy sources. It might be when the oil has to be mined from 5000 feet below the ocean surface or when they have to drill miles into continental bedrock or when tar sands have to be utilized, but there must be a point where the amount of energy going into the extraction of oil is nearly the same as the amount of oil extracted. At that point, there's no need to extract any oil since becomes a zero sum gain. I've always heard the argument that alternative energy sources will become much more cost effective in the run up to the zero sum gain on oil, so we'll probably never reach that extreme.

The bottom line seems to be that there are still disagreements about whether peak oil theory will pan out or not. The oil consultants say no, and a bunch of academics say yes. Hmm, interesting. Like other, strangely similar, "debates," the answer will likely be learned in the next couple of decades. And also like those other issues, by the time we find out the answer, it might already be too late to change course without drastically impacting all of our lives.

The future of energy: oil sands

According to an article from Agence France-Presse, ExxonMobil's Canadian subsidiary is going ahead with a $7BILLION project in Alberta to mine oil out of the oil sands. It's supposed to eventually produce 300,000 barrels per day. That's a spicy meatball.

The company is also touting (read: "greenwashing") it's carbon emissions and efficiency standards, claiming to have reduced emissions by 7% last year. To their credit, they aren't talking about reducing their use of fossil fuels, just being more efficient with them.

What does it all mean? ExxonMobil's products account for a gigantic chunk of fossil fuel carbon emissions, and the fact that they are pouring billions of dollars into expansion means they don't expect to be selling less fossil fuel any time soon. That they are getting more efficient in their treatment of fossil fuel just indicates that they are trying to squeeze every last penny from the cheap fuel (and also get to claim they are being "green"). At the end of the day, these stories are the ones that make me pessimistic that anything will abate humanity's appetite for cheap, dirty energy. Sure there is hope in increasingly aggressive restrictions and regulation of carbon emissions, but with the power/money behind the ExxonMobils of the world, it's hard to imagine that they don't have plenty of wiggle room, nor that they will fail to get more wiggle room built into future regulations.

Or maybe I'm just having a bad day. Read more about ExxonMobil's intersection with climate and environmental issues in a WaPo piece from a couple years ago by Steven Mufson.
