Going for the top kill.
BP is set to try a top kill tomorrow on the MC252 well in the Gulf.
Effectively, a top kill consists of injecting heavy fluids under high pressure down into the well bore. The weight of those fluids (i.e. the “head”) counters the pressure of the oil and gas coming up the well bore, and the end result is a “kill”.
Then, BP can come back in with cement and permanently plug the well.
The key is that the fluid you’re injecting needs to be very heavy. Drilling fluid is typically used; it’s used on the drilling process for the exact same purpose, to contain fluids in the well bore.
The other requirement is that you must be able to inject that heavy fluid under enough pressure to initially overcome (or overpower, if you will) the opposing pressure of the oil and gas condensate coming the pipe.
Good luck BP. I’m excited to see if this works. It’s never been done in deep water.
