Endless Oil

Technology, politics, and lower demand will yield a bumper crop of crude

…Schoonebeek will not flood the world with crude. But its success presents a stiff challenge to those who argue that oil production is in irreversible decline. Consumer demand, technology, and global politics are shifting in a way that could spell a future of oil abundance, not of catastrophic dearth. As Leonardo Maugeri, a senior executive at Italian oil major ENI, puts it: “There will be enough oil for at least 100 years.”

Many analysts and industry executives have little doubt that there’s plenty of oil in the ground. “Only about 32% of the oil [in reserves] is produced,” says Val Brock, Shell’s head of business development for enhanced oil recovery. Shell estimates 300 billion barrels and maybe more might be squeezed out of existing fields, much of it once thought beyond retrieval. Peter Jackson, Cambridge Energy Research Associates’ London-based senior director for oil industry activity, has reviewed data from the world’s biggest fields. His conclusion: 60% of their reserves remain available.

The fact that there’s still oil for the taking is driving Shell and other majors to come up with new technologies, which are expensive to develop but worth it when crude is riding high. While the price has fallen considerably from the peak of $147 per barrel in 2008, it is still far above what many oilmen expected a few years ago. “You will see companies going into the deep water, going into the arctic, using the best technology,” says Maugeri, who sees the oil industry as a dynamic system that responds rapidly to changes in the economic and political environment.

Even if the new technologies add just a few percentage points to the recovery rate, such gains add years to global supply and boost the industry’s profits. So the technology of coaxing oil out of the ground is constantly improving. Heating up heavy oil, as at Schoonebeek, is one new trick. Companies can add heavy polymers to the water they blast into a production site to push more oil out; the polymers add weight to the water and increase the pressure on deposits. (Shell is trying such technology on the Marmul field in Oman.) Another tactic is to inject soap into the ground to break the surface tension that makes leftover oil cling to the rock.
