BP shutting down Major Alaska oil field

BP shutting down Major Alaska oil field

ANCHORAGE, Alaska - In a sudden blow to the nation's oil supply, half the production on Alaska's North Slope was being shut down Sunday after BP Exploration Alaska, Inc. discovered severe corrosion in a Prudhoe Bay oil transit line.

BP officials said they didn't know how long the Prudhoe Bay field would be off line. "I don't even know how long it's going to take to shut it down," said Tom Williams, BP's senior tax and royalty counsel.

Once the field is shut down, in a process expected to take days, BP said oil production will be reduced by 400,000 barrels a day. That's close to 8 percent of U.S. oil production as of May 2006 or about 2.6 percent of U.S. supply including imports, according to data from the U.S. Energy Information Administration.

The shutdown comes at an already worrisome time for the oil industry, with supply concerns stemming both from the hurricane season and instability in the Middle East.

"We regret that it is necessary to take this action and we apologize to the nation and the State of Alaska for the adverse impacts it will cause," BP America Chairman and President Bob Malone said in a statement.

A 400,000-barrel per day reduction in output would have a major impact on oil prices, said Tetsu Emori, chief commodities strategist at Mitsui Bussan Futures in Tokyo.

"Oil prices could increase by as much as $10 per barrel given the current environment," Emori said. "But we can't really say for sure how big an effect this is going to have until we have more exact figures about how much production is going to be reduced."

Victor Shum, an energy analyst with Purvin & Gertz in Singapore, said he expected the impact to be minimal.

"The U.S. market is actually well-supplied; crude inventories are very high," he said. "So while this won't have any immediate impact on U.S. supplies, the market is in very high anxiety. So any significant disruption, traders will take that into account, even though there is no threat of a supply shortage."

Light, sweet crude for September delivery was up 36 cents to $74.95 a barrel in midmorning Asian electronic trading on the New York Mercantile Exchange.
