The oil well and the damage done

摘要

"Who cares, it's done, end of story, W will probably be fine." Thus, in an e-mail, a manager at bp wrote of the decision to use only a few "centralisers" when cementing into place the pipe that ran from an oil reservoir 13,000 feet (4,000 metres) below the sea floor to Deepwater Horizon, the drilling rig floating 5,000 feet above it. The cement failed-considerably more likely with fewer centralisers, experts say-four days after the e-mail was sent, on April 20th. Oil and gas rushed up the well, dooming the rig and 11 of her crew.
