BP toils on oil ‘top kill’, Obama fights criticism

WASHINGTON/VENICE, La., (Reuters) – BP Plc said its  high-stakes bid to plug a gushing Gulf of Mexico oil well was  proceeding to plan yesterday, while U.S. President Barack  Obama fended off criticism he has been too slow to respond to  the worst oil spill in U.S. history.

Nearly 40 days into the disaster, the BP oil leak has now  eclipsed the worst previous spill, the Exxon Valdez wreck on  the Alaska coast in 1989, according to new U.S. government  estimates of the amount of oil spewing into the Gulf.

BP’s “top kill” procedure launched on Wednesday could choke  off the well a mile (1.6 km) down on the sea floor, but BP said  it needs another 24 hours or longer to know the outcome.

A day before he visits the Gulf for the second time, Obama  vowed to hold BP accountable, saying was “angry and frustrated”  at the London-based company’s failure to plug the leak.

“In case you’re wondering who’s responsible, I take  responsibility,” he told a White House news conference. “It is  my job to make sure everything is done to shut this down.”

He announced a six-month extension of a moratorium on  permits for new deepwater oil drilling while a commission  investigates the causes of the disaster, and ordered 33  deepwater exploratory wells in the Gulf of Mexico to suspend  work while they meet new safety requirements.

The move is a setback to offshore exploration and a  potential blow to Obama’s efforts to rejig U.S. energy policy.

The political fallout from the spill also claimed its  highest-profile victim as the head of the government agency  that oversees offshore oil drilling resigned.

All eyes are on the top kill, the pumping of heavy fluid  into the well to stop the gusher before capping it with cement.  BP stopped pumping to analyze data, but resumed later Thursday,  said BP chief operating officer Doug Suttles.
