In a story that ran Aug. 11 about the partial shutdown of an oil field in Prudhoe Bay, Alaska, The Associated Press, relying on information from BP PLC, erroneously reported that the eastern pipeline had not undergone a high-tech "smart pig" inspection since 1992. On Saturday, Aug. 12, the company told the AP that some of its employees were misinformed, and that the eastern pipeline, which began operating in 1977, never had the smart pig inspection. Below is a corrected version of the story:

PRUDHOE BAY, Alaska (AP) - Federal regulators ordered BP PLC to conduct more rigorous tests of oil pipelines Thursday as the company said it might keep nearly half of the nation's largest oil field open despite leaks and severe corrosion.
The Department of Transportation ordered four daily surveys of all pipelines as BP announced it might not have to shut down its entire Prudhoe Bay operations. BP said it would comply with the order.
The eastern side of the field was closed Tuesday after a small spill, but about 140,000 barrels of oil continued to flow Thursday from the western side, said Craig Wiggs, a performance unit leader for BP. Before the company started shutting down operations, the field produced 400,000 barrels a day.
If the western side kept flowing, that would mean the company would be able to maintain the daily 140,000-barrel capacity - and possibly ramp up to 185,000 barrels - while work continues on the eastern side.
But in order to keep that oil flowing, BP must strip insulation from the pipes and conduct ultrasonic testing, the department's Pipeline and Hazardous Materials Safety Administration said.
The test will give a picture of the pipe's health that is similar to a sonogram, typically used to view a fetus in the womb. The company also will be required to use heat-seeking infrared equipment to detect leaks and must visually inspect by foot, car or plane all 22 miles of transit lines.
The company must also pass inspections before restarting its eastern operation.
Steve Marshall, president of BP Exploration Alaska, said the company was assessing Thursday what needs to be done to keep the operation going. A decision on whether to continue operations at its western field will be made early next week.
Wiggs said the company had initially decided to shut down the entire field because the leak on the eastern side made officials question their earlier inspections throughout the pipeline. But now, Wiggs said, the company was rethinking whether it could keep the western line open.
"It's a line we have the best confidence in," Wiggs said. "We've spent lots of time inspecting it in March, April and May after the spill."
The long-term plan would still be to replace the pipeline on the west side, which is where the company discovered a massive spill of up to 267,000 gallons in March.
BP also said it takes full responsibility for the lack of upkeep that led to the severe corrosion and shutdown.
"BP is the operator of the field. We're ultimately responsible," said Kemp Copeland, manager of the Prudhoe Bay oil field.
Interesting when describing how little oil is flowing, barrels are the unit of measure. But when describing how big the earlier spill was, gallons are the unit of measure.
Never been pigged? That is unsat!
Until 2000, this part of Prudhoe Bay (the East Operating Area) was operated by ARCO, not BP.
Is BP run by Muslims?
