BP said Thursday that "top kill" operations, begun Wednesday afternoon, continued overnight and are ongoing. "There are no significant events to report at this time," BP said in a brief statement. "BP will provide updates on progress as appropriate." Late Wednesday, Chief Operating Officer Doug Suttles said that 7,000 barrels of drilling mud had been pumped into the blowout preventer on the sea bed, a mile below the surface. BP will also pump cement into the blowout preventer, he said. At the same time, BP has plans to sever the broken pipe at the bottom of the Gulf and attach a new blowout preventer if the top kill procedure doesn't work, he said. Moreover, the company's continuing to drill relief wells to stop the disastrous leak. In Washington, Obama will announce a decision to keep a moratorium on new offshore drilling in place for six more months as a White House commission studies the practice, according to reports. An August lease auction of drilling rights in the western Gulf reportedly will be cancelled, along with another off the coast of Virginia. Obama will also delay exploration plans off the Alaska coast in the Chukchi and Beaufort seas, according to a White House aide cited by news service AFP. Meanwhile, a more detailed picture is emerging about the deadly April 20 explosion and the April 22 sinking of the Deepwater Horizon rig, which caused the massive oil rupture 50 miles off the Louisiana coast. Largely confirming earlier media reports, Transocean Ltd. supervisors who were aboard the rig told federal officials Wednesday about a disagreement with their BP counterparts hours before the blast that killed 11. In a joint hearing held by the Coast Guard and the Minerals Management Service in Louisiana, Douglas Brown, Transocean's chief mechanic on the rig, said that key representatives from both companies had a heated argument in an 11 a.m. meeting that morning, according to a Wall Street Journal report. Brown said Transocean's crew leaders objected to a decision by BP on how to start removing heavy drilling fluid and replace it with lighter seawater from a riser pipe connected to the well head. BP declined to comment on the testimony.
