BP is running tests and expected to decide shortly if it will go ahead with an effort to choke off its oil gusher by force-feeding it heavy drilling mud and cement. “Top kill’ is an operation in which heavy mud and cement would be shot into the blown-out well to plug it up. Video Rating: 4 / 5
GULF OF MEXICO – The mobile offshore drilling unit Q4000 holds position directly over the damaged Deepwater Horizon blowout preventer as crews work to plug the wellhead using a technique known as “top kill,” May 26, 2010. The procedure is intended to stem the flow of oil and gas and ultimately kill the well by injecting heavy drilling fluids through the blow out preventer on the seabed, down into the well. A nearby vessel sprays sea water near the surface of Q4000 to keep oil and fumes from interfering with operations. U.S. Coast Guard video by Petty Officer 3rd Class Patrick Kelley.

Animation showing the Top Kill process designed to stop the flow of oil from the well. Heavy “kill mud” is pumped down a drill pipe, then through hoses that go through the manifold on the seafloor. The mud then moves through another set of hoses attached to the Deepwater Horizon blow-out preventer’s choke and kill lines, then into the well. Recent Updates for Deepwater Horizon Response
