BP hired a top oilfield service company to test the strength of cement linings on the Deepwater Horizon’s well, but sent the firm’s workers home 11 hours before the rig exploded April 20 without performing a final check that a top cementing company executive called “the only test that can really determine the actual effectiveness” of the well’s seal.
