BP’s renewed efforts at plugging the flow of oil from its runaway well in the Gulf of Mexico stalled again on Friday, as the company suspended pumping operations for the second time in two days, according to a technician involved with the response effort. In an operation known as a “junk shot,” BP engineers poured pieces of rubber, golf balls and other materials into the crippled blowout preventer, trying to clog the device that sits atop the wellhead. The maneuver was designed to work in conjunction with the continuing “top kill” operation, in which heavy drilling liquids are pumped into the well to counteract the pressure of the gushing oil.
If the efforts succeeded, officials intended to pump cement into the well to seal it. But the company suspended pumping operations at 2:30 a.m. Friday after two junk shot attempts, said the technician, who spoke on the condition of anonymity because he was not authorized to speak publicly about the efforts.The suspension of the effort was not announced, and appeared to again contradict statements by company and government officials that suggested the top kill procedure was progressing Friday.
