BP said Thursday it plans to boost its ability to capture the oil gushing from a ruptured well in the Gulf of Mexico by early next week as the Obama administration announced that the oil giant agreed to speed up payments to people whose livelihoods have been washed away by the spill. At the bottom of the sea, the containment cap on the leaking well is capturing 630,000 gallons a day and pumping it to a ship at the surface, and the amount could nearly double by next week to roughly 1.17 million gallons, the Coast Guard has said. The government has estimated 600,000 to 1.2 million gallons are leaking per day, but a scientist on a task force studying the flow said the actual rate may be between 798,000 gallons and 1.8 million. A second vessel expected to arrive within days should greatly increased capacity. BP also plans to bring in a tanker from the North Sea to help transport oil and an incinerator to burn off some of the crude.
