BP Relied on Faulty U.S. Data
By NEIL KING JR. And KEITH JOHNSON
BP PLC and other big oil companies based their plans for responding to a big oil spill in the Gulf of Mexico on U.S. government projections that gave very low odds of oil hitting shore, even in the case of a spill much larger than the current one.
The government models, which have not been updated since 2004, assumed that most of the oil would rapidly evaporate or get broken up by waves or weather. In the weeks since the Deepwater Horizon caught fire and sank, real life has proven these models wrong.
The government's optimistic forecasts reinforced the oil industry's confidence in its spill-prevention technology, leading to decisions that left both oil companies and the government ill-prepared for the disaster that has unfolded in the Gulf since April 20.
