Permanent plug being pumped into BP's gulf well
Crews are pumping cement into BP’s blown-out oil well thousands of feet below the sea bottom, working to permanently seal it.
Engineers initially had planned to pump in mud before the cement, but a BP spokesman said that would not be necessary. There was no pressure building inside the well, so the mud wasn’t needed.
BP expects that the well will be completely sealed – and declared permanently dead – sometime today.
The catastrophe began on April 20, when an explosion killed 11 workers, sank a drilling rig and led to the worst offshore oil spill in US history.
