BP Preparing 'Top Kill' to Stop Leaking Oil Well in Gulf of Mexico VOA News 25 May 2010 A contractor operates an oil skimmer in Pass a Loutre, Louisiana, 24 May 2010 Photo: AP A contractor operates an oil skimmer in Pass a Loutre, Louisiana, 24 May 2010 Oil company BP is preparing an operation to completely plug a broken deep-sea well spewing crude oil into the Gulf of Mexico. The company said Tuesday equipment is in place for the so-called "top kill" method, which involves pumping heavy drilling fluid into the well to stop the flow of oil and gas. BP says the operation, expected to begin Wednesday, has a 60 to 70 percent chance of success. Members of President Barack Obama's administration have expressed frustration with having to rely on BP to contain the spill washing ashore on the U.S. Gulf coast.  Interior Secretary Ken Salazar on Sunday said the government was ready to intervene. But a Coast Guard official overseeing the cleanup, Thad Allen, acknowledged that only BP has the equipment and expertise to attack the well 1,500 meters under water. The well ruptured when a BP-leased off-shore drilling rig exploded April 20, killing 11 workers. Since then, an unknown amount of oil has been spewing into the Gulf of Mexico. Crude oil washing up on U.S. shores has killed wildlife and is threatening fishing industries. Louisiana Governor Bobby Jindal said Monday the oil is fundamentally threatening people's way of life in the southern U.S. state. He lashed out at BP and federal officials on Sunday, saying he has not received the resources he requested to protect Louisiana's coastline. BP officials say the company's cost for responding to the spill has grown to $760 million. If the "top kill" operation does not work, BP says it will make another attempt to siphon away some of the oil spewing from the leaking well to a ship on the surface. The company claimed some success with a similar technique last week. BP is also drilling a pair of relief wells, considered the best option for stopping the leak. But it could take months for the drilling to be completed, meaning if current containment methods fail, oil could continue spilling into the Gulf.
