WSJ front page: Oil officials see limit

by Russell Gold and Ann Davis

A growing number of oil-industry chieftains are endorsing an idea long deemed fringe: The world is approaching a practical limit to the number of barrels of crude oil that can be pumped every day.

Some predict that, despite the world's fast-growing thirst for oil, producers could hit that ceiling as soon as 2012. This rough limit -- which two senior industry officials recently pegged at about 100 million barrels a day -- is well short of global demand projections over the next few decades. Current production is about 85 million barrels a day.

The world certainly won't run out of oil any time soon. And plenty of energy experts expect sky-high prices to hasten the development of alternative fuels and improve energy efficiency. But evidence is mounting that crude-oil production may plateau before those innovations arrive on a large scale. That could set the stage for a period marked by energy shortages, high prices and bare-knuckled competition for fuel.

The current debate represents a significant twist on an older, often-derided notion known as the peak-oil theory. Traditional peak-oil theorists, many of whom are industry outsiders or retired geologists, have argued that global oil production will soon peak and enter an irreversible decline because nearly half the available oil in the world has been pumped. They've been proved wrong so often that their theory has become debased.

The new adherents -- who range from senior Western oil-company executives to current and former officials of the major world exporting countries -- don't believe the global oil tank is at the half-empty point. But they share the belief that a global production ceiling is coming for other reasons: restricted access to oil fields, spiraling costs and increasingly complex oil-field geology. This will create a global production plateau, not a peak, they contend, with oil output remaining relatively constant rather than rising or falling.

The emergence of a production ceiling would mark a monumental shift in the energy world.

...Oil companies have seen several years of bull-market prices, and thus of trying to produce more. This has given their executives a better sense of what is and isn't possible.

One limit: Many people think most of the world's giant fields already have been discovered.

...Compounding the problem: Most of the world's biggest fields are aging, and production at them is declining rapidly.

...Oil executives who believe a production ceiling is coming are making plans to stay relevant in a world where oil production is constrained. ...
