VOA常速英语:US Oil Surge Could Impact Mideast Geopolitics

LONDON — The United States will account for a third of new oil supplies over the next five years, and will become energy self-sufficient in 20 years, according to a new report by the Paris-based International Energy Agency (IEA).

Although U.S. oil imports from Arab Gulf countries increased last year, analysts predict the U.S. will lose its dependence on Middle East imports, which is expected to have a huge impact on international relations and the balance of power.

The International Energy Agency (IEA)  describes a US 'supply shock' rippling through world oil markets.

John Mitchell, an oil market analyst at policy institute Chatham House in London, "The key to it is the resurgence of shale development in the United States. It has been building up over some years, but only in the last three years has it rached big proportions.

Shale oil and gas are extracted using pressurized fluid to blast the product out from the rock, a process known as hydraulic fracturing or 'fracking.' Some U.S. states and European countries have banned the practice over fears that it may cause pollution and even earthquakes.

But the technology will help the United States become largely self-sufficient in oil by 2035, according to the IEA. U.S. gas production is expected to overtake Russia.

When that happens, the concept of energy security will no longer dictate U.S. foreign policy.

"Will the Middle East still be so dependent on U.S. military support?" Mitchell asked. "I am sure the answer is probably yes, but maybe the U.S. does not have quite the same interest in that as it did before.

A more energy self-sufficient United States has dramatic implications for Middle East politics, according to Christopher Davidson of England's University of Durham, and author of the book After the Sheikhs: The Coming Collapse of the Gulf Monarchies.

"What we are also likely to see is the United States start to hedge its positions a bit better on the Gulf monarchies," Davidson said. "As it loses the dependent nature of this economic partnership, we are perhaps starting to see the U.S. already starting to reach out to opposition groups in Bahrain, for example, and increasingly in Saudi Arabia.

In the midst of the Arab Spring, Davidson says many oil-rich Gulf monarchies are trying to pacify their populations with government handouts. Falling receipts from oil exports could trigger political upheaval.

"Within just a couple of years we'll have a public spending deficit in most of the Gulf monarchies," Davidson said. "At the same time, we are also seeing the demonstration effect of the Arab Spring in Syria and north Africa starting to embolden the people of these countries. They are no longer willing to tolerate autocracy.

Davidson says Gulf states will be gearing their oil exports eastwards in the coming decades.

"However, what is missing is the security relationship that the Western powers have historically provided to the Gulf," he said. "The Gulf states know, and I suspect they are bluffing, that China and the Pacific Asian states cannot replace the West as this ultimate security guarantor.

Analysts say the oil boom will give the U.S. economy a competitive advantage with cheap energy supplies no longer vulnerable to global geopolitics.
