What is a 'top kill'? A graphic presentation by BBC News

[tencats]

BP is using a "top kill" procedure to stop the Gulf of Mexico oil spill. But what exactly is "top kill"?

One way to think about "top kill" is to imagine something sitting on a spring.

Put a heavy enough weight down on the spring and it will be squashed down. But put something on that's too light and the object will be thrown off.

In this case, the "spring" is oil and gas coming out of the reservoir, beneath the sea, at the site of the well drilled by the Deepwater Horizon and at pressures exceeding 5,000lb (2,268kg) per square inch.
