As recently reported by The Wall Street Journal, oil production has begun falling at all of the major Western oil companies, and they are finding it harder than ever to find new prospects even though they are awash in profits and eager to expand.  As the article notes:

“…Part of the reason is political. From the Caspian Sea to South America, Western oil companies are being squeezed out of resource-rich provinces. They are being forced to renegotiate contracts on less-favorable terms and are fighting losing battles with assertive state-owned oil companies.

And much of their production is in mature regions that are declining, like the North Sea.

The reality, experts say, is that the oil giants that once dominated the global market have lost much of their influence — and with it, their ability to increase supplies.

…Along with mature fields, the companies have contracts with producing countries whose governments allocate fewer barrels to oil companies as prices rise.

“It has become really, really difficult to grow production,” said Paul Horsnell, an analyst at Barclays Capital. “International companies have a portfolio of assets in areas of significant decline and no frontier discoveries to make up for that.”

…The new oil order has been emerging for a few decades.

As late as the 1970s, Western corporations controlled well over half of the world’s oil production. These companies — Exxon Mobil, BP, Royal Dutch Shell, Chevron, ConocoPhillips, Total of France and Eni of Italy — now produce just 13 percent.

Today’s 10 largest holders of petroleum reserves are state-owned companies, like Russia’s Gazprom and Iran’s national oil company.

Sluggish supplies have prompted a cottage industry of doomsday predictions that the world’s oil production has reached a peak. But many energy experts say these “peak oil” theories are misplaced. They say the world is not running out of oil — rather, the companies that know the most about how to produce oil are running out of places to drill.

“There is still a lot of oil to develop out there, which is why we don’t call this geological peak oil, especially in places like Venezuela, Russia, Iran and Iraq,” said Arjun Murti, an energy analyst at Goldman Sachs. “What we have now is geopolitical peak oil.”

Western companies are far better than most national oil companies at finding and extracting petroleum, experts say. They have developed advanced exploration technologies and can muster significant financing to develop new fields. Many of the world’s exporting states, however, have spurned their expertise.

Oil company executives see a straightforward explanation: a trend known as resource nationalism. They contend that they have been shut out of promising regions by a rising assertiveness in the Middle East, in Russia, in South America and elsewhere by governments determined to keep full control of their oil.”
