The Coming Decline of Oil
Oil has shaped our twenty-first century civilization, affecting every facet of the economy from the mechanization of agriculture to jet air travel. When production turns downward, it will be a seismic economic event, creating a world unlike any we have known during our lifetimes. Indeed, when historians write about this period in history, they may well distinguish between before peak oil (BPO) and after peak oil (APO). (See also see Chapter 2, "Beyond the Oil Peak," Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble, available for free online.)
One way the oil prospect can be analyzed is by separating the world's principal oil-producing countries into two groups—those where production is falling and those where it is still rising—is illuminating. Of the 23 leading oil producers, output appears to have peaked in 15 and to still be rising in eight. The post-peak countries range from the United States (the only country other than Saudi Arabia to ever pump more than 9 million barrels of oil per day) and Venezuela (where oil production peaked in 1970) to the two North Sea oil producers, the United Kingdom and Norway, where production peaked in 1999 and 2000 respectively. U.S. oil output, which peaked at 9.6 million barrels a day in 1970, dropped to 5.4 million barrels a day in 2004—a fall of 44 percent. Venezuela's output has dropped 31 percent since 1970.
The eight pre-peak countries are dominated by the world's leading oil producers, Saudi Arabia and Russia. Other countries with substantial potential for increasing production are Canada, largely because of its tar sands, and Kazakhstan, which is still developing its oil resources. The other four pre-peak countries are Algeria, Angola, China, and Mexico.
The biggest question mark among these eight countries is Saudi Arabia. Its production technically peaked in 1980 at 9.9 million barrels a day and output is now nearly 1 million barrels a day below that. It is included as a country with rising production only on the basis of statements by Saudi officials that the country could produce far more. However, some analysts doubt whether the Saudis can raise output much beyond its current production. Some of its older oil fields are largely depleted, and it remains to be seen whether pumping from new fields will be sufficient to more than offset the loss from the old ones.
This analysis comes down to whether production will actually increase enough in the eight pre-peak countries to offset the declines under way in the 15 countries where production has already peaked. In volume of output, the two groups have essentially the same total production capacity. If production begins to fall in any one of the eight, however, world output could decline.
Another way to consider oil production prospects is to look at the actions of the major oil companies themselves. While some CEOs sound very bullish about the growth of future production, their actions suggest a less confident outlook.
One bit of evidence of this is the decision by leading oil companies to invest heavily in buying up their own stocks. ExxonMobil, for example, with the largest quarterly profit of any company on record—$10.7 billion in the fourth quarter of 2005—invested nearly $10 billion in buying back its own stock. ChevronTexaco used $2.5 billion of its profits to buy back stock. With little new oil to be discovered and world oil demand growing fast, companies appear to be realizing that their reserves will become even more valuable in the future.
Closely related to this behavior is the lack of any substantial increases in exploration and development in 2005 even with oil prices well above $50 a barrel. This suggests that the companies agree with petroleum geologists who say that 95 percent of all the oil in the world has already been discovered. "The whole world has now been seismically searched and picked over," says independent geologist Colin Campbell. "Geological knowledge has improved enormously in the past 30 years and it is almost inconceivable now that major fields remain to be found." This also implies that it may take a lot of costly exploration and drilling to find that remaining 5 percent.
The geological evidence suggests that world oil production will be peaking sooner rather than later. Matt Simmons, head of the oil investment bank Simmons and Company International and an industry leader, says in reference to new oil fields: "We've run out of good projects. This is not a money issue if these oil companies had fantastic projects, they'd be out there [developing new fields]." Kenneth Deffeyes, a highly respected geologist and former oil industry employee now at Princeton University, says in his 2005 book, Beyond Oil, "It is my opinion that the peak will occur in late 2005 or in the first few months of 2006." Walter Youngquist and A.M. Samsan Bakhtiari of the Iranian National Oil Company both project that oil will peak in 2007.
Sadad al-Husseini, recently retired as head of exploration and production at Aramco, the Saudi national oil company, notes that new oil output coming on-line had to be sufficient to cover both annual growth in world demand of at least 2 million barrels a day and the annual decline in production from existing fields of over 4 million barrels a day. "That's like a whole new Saudi Arabia every couple of years," Husseini said. "It's not sustainable."
