Oil, Oil, Everywhere . . .


Oil, Oil, Everywhere . . .

The price of oil remains high only because the cost of oil remains so low. We remain dependent on oil from the Mideast not because the planet is running out of buried hydrocarbons, but because extracting oil from the deserts of the Persian Gulf is so easy and cheap that it's risky to invest capital to extract somewhat more stubborn oil from far larger deposits in Alberta.


The cost of oil comes down to the cost of finding, and then lifting or extracting. First, you have to decide where to dig. Exploration costs currently run under $3 per barrel in much of the Mideast, and below $7 for oil hidden deep under the ocean. But these costs have been falling, not rising, because imaging technology that lets geologists peer through miles of water and rock improves faster than supplies recede. Many lower-grade deposits require no new looking at all.

To pick just one example among many, finding costs are essentially zero for the 3.5 trillion barrels of oil that soak the clay in the Orinoco basin in Venezuela, and the Athabasca tar sands in Alberta, Canada. Yes, that's trillion -- over a century's worth of global supply, at the current 30-billion-barrel-a-year rate of consumption.

Then you have to get the oil out of the sand -- or the sand out of the oil. In the Mideast, current lifting costs run $1 to $2.50 per barrel at the very most; lifting costs in Iraq probably run closer to 50 cents, though OPEC strains not to publicize any such embarrassingly low numbers. For the most expensive offshore platforms in the North Sea, lifting costs (capital investment plus operating costs) currently run comfortably south of $15 per barrel. Tar sands, by contrast, are simply strip mined, like western coal, and that's very cheap -- but then you spend another $10, or maybe $15, separating the oil from the dirt. To do that, oil or gas extracted from the site itself is burned to heat water, which is then used to "crack" the bitumen from the clay; the bitumen is then chemically split to produce lighter petroleum.

In sum, it costs under $5 per barrel to pump oil out from under the sand in Iraq, and about $15 to melt it out of the sand in Alberta. So why don't we just learn to love hockey and shop Canadian? Conventional Canadian wells already supply us with more oil than Saudi Arabia, and the Canadian tar is now delivering, too. The $5 billion (U.S.) Athabasca Oil Sands Project that Shell and ChevronTexaco opened in Alberta last year is now pumping 155,000 barrels per day. And to our south, Venezuela's Orinoco Belt yields 500,000 barrels daily.

But here's the catch: By simply opening up its spigots for a few years, Saudi Arabia could, in short order, force a complete write-off of the huge capital investments in Athabasca and Orinoco. Investing billions in tar-sand refineries is risky not because getting oil out of Alberta is especially difficult or expensive, but because getting oil out of Arabia is so easy and cheap. Oil prices gyrate and occasionally spike -- both up and down -- not because oil is scarce, but because it's so abundant in places where good government is scarce. Investing $5 billion dollars over five years to build a new tar-sand refinery in Alberta is indeed risky when a second cousin of Osama bin Laden can knock $20 off the price of oil with an idle wave of his hand on any given day in Riyadh.

The one consolation is that Arabia faces a quandary of its own. Once the offshore platform has been deployed in the North Sea, once the humongous crock pot is up and cooking in Alberta, its cost is sunk. The original investors may never recover their capital, but after it has been written off, somebody can go ahead and produce oil very profitably going forward. And capital costs are going to keep falling, because the cost of a tar-sand refinery depends on technology, and technology costs always fall. Bacteria, for example, have already been successfully bioengineered to crack heavy oil molecules to help clean up oil spills, and to mine low-grade copper; bugs could likewise end up trampling out the vintage where the Albertan oil is stored.

In the short term anything remains possible. Demand for oil grows daily in China and India, where good government is finally taking root, while much of the earth's most accessible oil lies under land controlled by feudal theocracies, kleptocrats, and fanatics. Day by day, just as it should, the market attempts to incorporate these two antithetical realities into the spot price of crude. But to suppose that those prices foreshadow the exhaustion of the planet itself is silly.

The cost of extracting oil from the earth has not gone up over the past century, it has held remarkably steady. Going forward, over the longer term, it may rise very gradually, but certainly not fast. The earth is far bigger than people think, the untapped deposits are huge, and the technologies for separating oil from planet keep getting better. U.S. oil policy should be to promote new capital investment in the United States, Canada, and other oil-producing countries that are politically stable, and promote stable government in those that aren't.
