"BP Aims To Plug Gulf Oil Well for Good With Two-Pronged 'Kill' Shot"

"The next shot at killing BP's well in the Gulf of Mexico could begin as early as Monday night, as engineers plan to pump heavy mud into the capped but still dangerous well and "bullhead" the rogue oil back down into its source rock 2 1/2 miles below the seafloor. The "static kill" is part of a double whammy of mud and cement that would hit the runaway Macondo well high and low in quick succession. The static kill starts at the top, firing the mud and possibly cement into the blowout preventer that sits on the wellhead. That effort, which would take a day or two, would be followed in another five to seven days by the start of the more laborious "bottom kill," in which mud and cement will be injected into Macondo through a relief well that engineers began drilling at the beginning of May."
