Thirty-six days after the Deepwater Horizon exploded, killing 11 crew members and setting off a massive oil leak, BP may finally be ready to attempt to seal the drill site with a “top kill” of heavy mud followed by cement.
I’ve seen estimates of success at 60 to 70 percent, so keep your fingers crossed.
All of them. It’s a critical moment, the last best chance to stop the flow for weeks if not months. If this doesn’t work…
Here’s how BP describes the process:
“A total of 50,000 barrels of mud will be on location to kill the well – far more than necessary, but we want to be prepared for anything. Pumping capacity on location is more than 30,000 hydraulic horsepower.
The mud will be pumped down the 6-5/8 inch drill pipe (pipe is connected to the Q4000), then through 3-inch hoses, which go through the manifold on the seafloor. Then the mud moves through another set of 3-inch hoses attached to the Deepwater Horizon BOP choke and kill lines.
With the manifold, we can also pump
