top kill

procedure used as a means of sealing an oil well that is experiencing an uncontrolled eruption of crude oil or natural gas. The process involves pumping heavyweight drilling mud into the manifolds connected to the top of the well. This procedure stops the flow of oil and gas from the well and is a prelude to sealing the well completely (usually with cement).

BP engineers had injected a "junk shot" of heavier blocking materials as part of the "top kill" procedure being attempted.
