Oil spill hearings: BP didn’t test mud prior to critical pipeline procedure, driller testifies

This is an update from the joint hearings of the U.S. Coast Guard and Minerals Management Service held in Kenner on Saturday into the explosion and fire aboard the Deepwater Horizon oil rig on April 20, which killed 11 workers and created the Gulf of Mexico oil spill currently fouling Louisiana’s coast.
BP decided not to perform a test on the mud at the bottom of the well before starting to place the final cement lining that may have been the source of gas that eventually blew out the well, according to testimony at investigative hearings in Kenner.
The top drilling supervisor on the Deepwater Horizon rig on April 20, Offshore Installation Manager Jimmy Harrell, testified Thursday that BP decided to forego a “bottoms-up” test that would have examined the condition of drilling mud sitting in the zone where a casing shoe was about to be placed to protect the well from natural gas or oil pressing in against the hole.
