BP Pours Cement Into Macondo

摘要

BP pumped cement down its blown-out Gulf of Mexico well on Thursday, sealing it off and setting up a planned permanent kill operation at the well which was the source of a massive oil spill. The cementing operation followed earlier injections of heavy drilling mud this week that had subdued the upward pressure of the oil and gas. The deepwater Macondo well was provisionally capped in mid-July. “This is not the end, but it will virtually assure us that no oil will be leaking into the environment,” retired Coast Guard Admiral Thad Allen, who oversees the US oil spill response operation, told a press briefing in Washington.
