    Because it was a last ditch effort. While the cementing of a well is common, you always kill the well first to where there is nothing flowing. This is commonly done by pumping heavy (10 pound brine at least) water or KCL gel down the shaft until the weight of the water becomes more than what the pressure coming out can push. Once this is done, a cement plug is set so that only the zone being produced is allowed to flow. If the well is being capped then it is cemented shut.

    On this particular well the have no way to shut the flow down to set a cement plug. They were going to have to pump against the flow and while that may have been done on regular wells a time or two, it has never been done offshore.

    The mud they are pumping is a dilatant fluid or shear force thickening. A fluid suspension with high solids content. You can make your own by combining 1 cup water and 2 cups corn starch. This will create a mixture of about 60% solids. If you slowly push your finger into it, you can penetrate to the bottom of the container. If you jam your finger forcefully, it sets up like cement.

    BP needs to pump this mud at a slightly higher pressure than the oil pushing up. If they pump too hard and create too much shear force, the mud will solidify and blow the pump up. Once enough mud is in the hole, they shut down the pump rapidly, the sudden force of the oil pressure pushing back causes the mud to solidify and stop the flow.

    On (roughly) Day 31 when it looked like the top kill approach would work, Bumble finally showed up and took credit for fixing the crisis.

    Now that top kill has failed let's all sit back and watch the hilarity at Bumble's next spin of the situation.

    For the record, I'm pissed that this disaster has festered for so long as this is no attempt at schadenfreude. Many heads at BP and the Fed (especially the MMS) should roll along with lengthy prison sentences.

    It's merely a poke at the Tool-in-chief.

    BP will not make it through this disaster. They are doomed.
