ROBERT, La. — The hypnotic video of mud, gas and oil billowing from the seafloor has become an Internet sensation as Americans watch to see whether BP’s effort to plug the gusher in the Gulf of Mexico succeeds.
BP warned Friday that it could be Sunday or later before the outcome of the cliffhanger becomes clear.
Scientists cautioned that few conclusions can be drawn with any certainty from watching the spillcam coverage of the “top kill.” But they said the video seemed to suggest BP was gaining ground.
In an operation that began Wednesday, BP has been pumping heavy drilling mud into the blown-out well in hopes of choking it off and putting an end to what is already the biggest oil spill in U.S. history, at anywhere from 18 million to 40 million gallons by the government’s estimate.
Coast Guard Adm. Thad Allen said the denser-than-water mud was able to push down the oil and gas coming up at great force from underground, but it had not overwhelmed the gusher. The trick is to pump the mud with such force that it stops the upward flow of oil, and it is impossible to know how much mud that will take.
BP chief operating officer Doug Suttles said Friday that the top kill was going basically as planned, though the pumping has stopped several times.
He said the company has also shot in assorted junk, including metal pieces and rubber balls, which seemed to be helping to counter pressure from the well.
A top kill has never been attempted 5,000 feet underwater, and public fascination is high. BP, under pressure from Congress, made available a live video feed of what is going on underwater, and about 3,000 websites were showing a version of it that the PBS “Newshour” offered for free.
Meanwhile, President Barack Obama visited the coast to see the damage as he tried to emphasize that his administration was in control of the crisis, which began April 20 when the Deepwater Horizon drilling platform blew up. Eleven workers were killed.
“I’m here to tell you that you are not alone, you will not be abandoned, you will not be left behind,” he told people in Grand Isle, where the beach has been closed by gobs of oil and the frustration and anger are palpable. “The media may get tired of the story, but we will not. We will be on your side, and we will see this through.”
