LONDON (MarketWatch) -- BP Plc's shutting down its Prudhoe Bay oil field in Alaska, taking some 400,000 barrels a day of crude oil off world markets, in the aftermath of the discovery of a corroded pipeline and a small leak.
The shutdown ordered by the British energy giant, one of the three major operators in the North Slope, was disclosed Sunday night and is expected to take several days to complete. The reduction represents almost half the total daily production from the North Slope, and about 8% of daily U.S. output.
