More On Iraqi Oil  

One reader brought this article from Gal Luft at The Brookings Institution to my attention.

I tried to work out if Brookings is a neocon thinktank or not, and came out of the experience completely confused - their major funders are the AEI (as right wing as it gets), Bill Gates, Theresa Heinz Kerry and Dianne Feinstein. Can anyone enlighten me - is this genuinely a non-partisan organisation ?

The article itself is pretty hawkish in tone, but it covers a range of opinions - its quite an interesting read if you're curious about the answer - it certainly underscores just how difficult it is to get reliable estimates about the size of oil reserves from anyone. I'm still none the wiser, but I wouldn't be surprised if it turns out that the ASPO estimate for Iraq is far less than the real figure (although I still tend to believe their estimates in general - its just Iraq that is a special case).

Now that Iraq's oil has been secured by coalition forces and hopefully will soon be brought back on stream, it is time to solve a potentially important mystery: how much Iraqi oil is actually there?

Over the past several months, news organizations and experts have regularly cited Department of Energy (DOE) Energy Information Administration (EIA) figures claiming that the territory of Iraq contains over 112 billion barrels (bbl) of proven reserves—oil that has been definitively discovered and is expected to be economically producible. In addition, since Iraq is the least explored of the oil-rich countries, there have been numerous claims of huge undiscovered reserves there as well—oil thought to exist, and expected to become economically recoverable—to the tune of hundreds of billions of barrels. The respected Petroleum Economist Magazine estimates that there may be as many as 200 bbl of oil in Iraq; the Federation of American Scientists estimates 215 bbl; a study by the Council on Foreign Relations and the James A. Baker III Institute at Rice University claimed that Iraq has 220 bbl of undiscovered oil; and another study by the Center for Global Energy Studies and Petrolog & Associates offered an even more optimistic estimate of 300 bbl—a number that would give Iraq reserves greater even than those of Saudi Arabia. In a Guardian interview before the war, Taha Hmud Moussa, Saddam's deputy oil minister, said that all of Iraq's oil reserves "will exceed 300bbl when all Iraq's regions are explored."

If true, this would mean that Iraq has roughly a quarter of all of the world's oil. These assessments have been repeatedly cited in news articles, conferences, think tank briefings, congressional testimonies, and academic works because they raise the prospect that America's energy security could significantly improve if Iraq were able to challenge Saudi Arabia's position as the world's preeminent oil producer.

AN UNREPORTED DEBATE

There is no doubt that Iraq has a huge oil potential that still needs to be developed, and once opened for exploration, it could again be one of the world's most attractive oil domains for investors. But the reserve estimates that have so far been accepted uncritically by the public have been challenged by many petrogeologists and have yet to be substantiated. This is an important problem given the wide range of important decisions being made regarding Iraq's future and the global energy market.

It is particularly important to verify the estimates of Iraqi reserves since the DOE figures stand in contrast to those of an equally reputable U.S. government organization. In its 2000 World Petroleum Assessment, the Department of the Interior's U.S. Geological Survey (USGS) presented figures based on extensive geologic studies by a team of more than 40 geoscientists claiming that, as of the end of 1995, Iraq had 100 bbl of proven reserves, of which 22 bbl had already been recovered. Hence, according to the USGS, Iraq's current proven reserves amount to only 78 bbl—only two-thirds of the DOE's more commonly accepted 112 bbl estimate.

When it comes to assessing Iraq's undiscovered reserves, the differences between the DOE and the USGS becomes even starker. According to the USGS—which is hardly a Chicken Little when it comes to reserve predictions—there is a 95 percent probability that Iraq has at least 14 bbl, a 50 percent probability that it has at least 45 bbl, but only a 5 percent probability that it has 84 bbl of undiscovered reserves. This means that the probability that Iraq has 200 bbl or 300 bbl, as so many of the reports have suggested, is, according to USGS calculations, close to nil.

The discrepancies between the United States' two chief government agencies dealing with energy assessments are so sharp that they present entirely contradictory images of Iraq's oil potential. If the DOE data is right, then Iraq has the world's second largest proven reserves. On the other hand, if the USGS figures are right (and they are also endorsed by the 2002 Energy Outlook of the Paris-based International Energy Agency, whose projections are recognized as authoritative throughout the energy world), then Russia would be second, with roughly twice the reserves of Iraq.

As for undiscovered reserves, external auditing is even more difficult and Iraq's claims are even more dubious. Issam al-Chalabi, Iraq's oil minister from 1987 to 1990, admitted in the March 24, 2003 issue of the OGJ that Iraq's oil figures are "preliminary in nature since work was often interrupted by political problems, and the technology used is now outdated." Large parts of the country, especially in Iraq's Western Desert and its northwest, are still untapped and need to be explored. This is where the DOE and USGS really part company. According to the DOE-EIA's Iraq web page, deep oil-bearing formations located in the vast Western Desert region could possibly yield as much as 100 bbl. This again contrasts with the detailed data of the USGS, which suggests only a 50 percent possibility of 6.6 bbl in Iraq's Western Desert petroleum system. Even under its most optimistic scenario, the USGS predicts no more than 14 bbl coming from this area.

However, there are some facts that are undisputed. First, Iraq has considerable oil reserves and low production costs. Second, because of Iraq's isolation over the last decade—during which exploration technology has greatly improved—there has been almost no use of the most sophisticated exploration techniques such as seismological surveys, magnetometers, and sniffers in Iraq. Furthermore, most of the fields have not been explored down to the deepest layers of the ground, where plenty of oil can be found. Out of the 74 fields that have been discovered and evaluated, only 15 are actually operating. In addition, there are 526 prospective drilling sites in Iraq today, but just 125 of them have actually been drilled. Of those, 90 have shown potential as oil fields, but only 30 have been even partially developed. This means that once on the ground with sophisticated exploration tools, petrogeologists could establish in relatively short time a far more accurate picture of the scope of Iraq's reserve than the one we have today.
