Guardian .Barack Obama ‘heartbroken’ as BP top kill fails to plug Gulf oil spill

BP has failed to stop the oil leak in the Gulf of Mexico using so-called top kill and junk shot techniques, prompting an exasperated response from Barack Obama.

After three days of pumping drilling mud over the leak and an attempt to plug the flow by blasting tyres, golf balls and other debris at it, BP admitted defeat last night. In its latest attempt to contain the worst oil spill in US history, it is to launch a four- to seven-day operation that will involve more oil leaking into the Gulf even if it works.

Obama described the setback as « enraging » and « heartbreaking », as documents emerged showing that BP engineers were concerned about the safety of the Deepwater Horizon rig months earlier than the company has admitted.

Papers obtained by the New York Times show that issues were raised as far back as last June. The problems involved the well casing and blowout preventer, considered critical pieces in the chain of events that led to the disaster.

Last night BP admitted the best hope of stemming the flow completely could take a further two months, using relief wells. BP’s chief operations officer, Doug Suttles, admitted: « We have not been able to stop the flow … This scares everybody, the fact that we can’t make this well stop flowing, the fact that we haven’t succeeded so far. »

He added: « Many of the things we’re trying have been done on the surface before, but have never been tried at 5,000ft. »
