Coast Guard: 11,000 Barrels of Oil Captured in Gulf in 24 Hours VOA News 07 June 2010 Booming operations continue off the coast of Orange Beach, Alabama, 07 Jun 2010 Photo: AP Booming operations continue off the coast of Orange Beach, Alabama, 07 Jun 2010 The U.S. official overseeing the government response to the Gulf of Mexico oil spill says a cap placed over the leaking well has captured 11,000 barrels of oil in a 24-hour period. Coast Guard Admiral Thad Allen says oil company BP hopes to boost that amount of captured oil to 20,000 barrels a day. He says the oil that has already spilled into the Gulf has broken up into "hundreds of thousands" of patches of oil. The admiral spoke at the White House Monday, before briefing President Barack Obama on the latest developments to contain the worst oil spill in U.S. history. Before the cap, about 20,000 barrels of oil were leaking each day into the Gulf, following the April 20 explosion and subsequent sinking of an oil rig off the coast of Louisiana. Admiral Allen says the effort to contain the flow is likely to continue for months, until relief wells now being drilled to completely stop the flow are completed. BP says it will try to install a second cap that could increase the amount of oil captured from the leaking well. It says the new device could be ready sometime next week. The oil giant says it has already spent $1.25 billion in its attempts to stop the leak and clean up the oil. It says that amount does not include $360 million to be spent on a project to build barrier islands to protect the Louisiana coastline from the oil. Increasing quantities of thick oily sludge are making their way eastward toward Florida, washing up on some of the region's pristine white sand beaches and coating marshes and wildlife in black ooze.
