Oil Spill, Gulf Oil Spill | featured news

Oil giant BP PLC said in an internal report posted on its website Wednesday morning that multiple companies and work teams contributed to the massive Gulf of Mexico spill that fouled waters and shorelines for months.

With the replacement of the failed blowout preventer and a cement plug in place, the well's seal is almost permanent, the federal spill response chief says. The final step will be to plug the well from the bottom.

A critical device at the center of an investigation into the Gulf oil rig explosion didn't undergo a rigorous recertification process in 2005 as required, a worker told investigators Wednesday.

A newly discovered type of oil-eating microbe is suddenly flourishing in the Gulf of Mexico.

BP was working to remove the failed blowout preventer from its ruptured well  — a key step towards killing the well and salvaging evidence that could help in the inquiry into the disaster.

BP Plc said on Friday it has completed a pressure test on its blown-out Gulf of Mexico well and those results are under review by government scientists and the British oil company.

BP PLC says it may in the future drill in the same Gulf of Mexico oil reservoir that blew its top and caused one of the world's worst spills. Officials said Friday at a news briefing in New Orleans that the company hasn't closed the door to tapping the reservoir again. Chief Operating Officer Doug Suttles says "there's lots of oil and gas here." He says "we're going to have to think about what to do with that at some point."

BP claimed a key victory Wednesday in the effort to plug its blown-out well as a government report said much of the spilled oil is gone — though what's left is still nearly five times the amount that poured from the Exxon Valdez.

Only about 26 percent of the oil from the Deepwater Horizon leak is still in the water or onshore, and most of it is diluted and breaking down rapidly, officials say.

Gov't scientists now estimate nearly 5 million barrels of oil have leaked into the Gulf since April, easily topping Mexico's 1979 spill of 3.3 million barrels | DAY 105Questions on Dispersants |
