BP to Begin Cementing Blown-Out Oil Well

Aug 5th, 2010 | By usnews | Category: U.S.

NEW ORLEANS — BP engineers planned to start shoving cement into the blown-out Gulf of Mexico oil well on Thursday, snaking it down to the sea floor through pipes to rest on mud already packed into the well.


BP said Wednesday it was finally able to force the oil back down to its underground reservoir with a slow torrent of heavy mud in an early step toward plugging the well up for good.


The news came as a federal report indicated only about a quarter of the spilled oil remains in the Gulf and is degrading quickly, with the rest contained, cleaned up or otherwise gone.


Despite the progress in the mud-pumping effort known as the “static kill,” U.S. officials are not ready to declare victory over the stubborn spill yet.


Federal officials including spill response commander Thad Allen, a retired Coast Guard admiral, also insist that BP crews must shove mud and cement into the reservoir feeding the well through the 18,000-foot relief well, which should be completed within weeks.


But for reasons that were unclear, BP officials have in recent days refused to commit to pumping cement down the relief well. BP officials have not elaborated on other options, but those could include using the well simply to test whether the reservoir is plugged.


“We have always said that we will move forward with the relief well. That will be the ultimate solution,” BP Senior Vice President Kent Wells said. “We need to take each step at a time. Clearly we need to pump cement. If we do it from the top, we might alter what we do with the relief well, but the relief well still a part of the solution.”


Whether the well is sealed or not, there’s still oil in the Gulf or on its shores — nearly 53 million gallons of it, according to the report Wednesday by the Interior Department and the National Oceanic and Atmospheric Administration. That’s still nearly five times the size of the Exxon Valdez spill, which wreaked environmental havoc in Alaska in 1989.


But almost three-quarters of the nearly 207 million gallons of oil that leaked overall has been collected at the well by a temporary containment cap, been cleaned up or chemically dispersed, or naturally deteriorated, evaporated or dissolved, the report said.


The remaining oil, much of it below the surface, remains a threat to sea life and Gulf Coast marshes, NOAA Administrator Jane Lubchenco said. But the spill no longer threatens the Florida Keys or the East Coast, the report said.


An experimental cap has stopped the oil from flowing for the past three weeks, but it was not a permanent solution.


Still, the static kill — also known as bullheading — probably would not have worked without that cap in place. It involved slowly pumping the mud from a ship down lines running to the top of the ruptured well a mile below.


President Barack Obama, while noting that people’s lives “have been turned upside down,” declared the operation was “finally close to coming to an end.”


But for the people who lost their livelihoods or still see oil washing up, the news was little consolation.


“There are still boats out there every day working, finding turtles with oil on them and seeing grass lines with oil in it,” said charter boat captain Randy Boggs, of Orange Beach, Ala. “Certainly all the oil isn’t accounted for. There are millions of pounds of tar balls and oil on the bottom.”


Harry “Cho-cho” Cherami, a 59-year-old shrimper who grew up on the deck of his father’s shrimp boat, said he’s also got good reason to be skeptical.


“I don’t think we’ve finished with this,” he said in Grand Isle, La. “We haven’t really started to deal with it yet. We don’t know what effect it’s going to have on our seafood in the long run.”
