HOUSTON — The Obama administration scrambled to respond on Sunday after the failure of the latest effort to kill the gushing oil well in the Gulf of Mexico. But administration officials acknowledged the possibility that tens of thousands of gallons of oil might continue pouring out until August, when two relief wells are scheduled to be completed.
“We are prepared for the worst,” said Carol M. Browner, President Obama’s climate change and energy policy adviser. “We have been prepared from the beginning.”
Even as the White House sought to demonstrate that it was taking a more direct hand in trying to solve the problem, senior officials acknowledged that the new technique BP will use to try to cap the leak — severing the riser pipe and placing a containment dome over the cut riser — could temporarily result in as much as 20 percent more oil flowing into the water during the three days to a week before the new device could be in place.
