BP: 60%-70% Chance 'Top Kill' Will Work Oozing oil, not confidence By Emily Rauhala, Newser User Posted May 25, 2010 8:08 AM CDT 10 comments Comments Oil oozes from the busted rig. (AP Photo/Senate Environment and Public Works Committee) (Newser) – BP's "containment dome" plan failed big time, and the oil giant is less than confident as it readies its latest and greatest plan for tomorrow: The "top-kill" maneuver, which Reuters reports the company thinks has a 60%-70% chance of succeeding. Tomorrow BP plans to inject heavy fluids and cement into the seabed well to try plug the hole—a ploy that's worked previously, but never at 5000 feet underwater. Those successes were in above-ground wells in the Middle East, notes CNN. If the "top kill" fails, BP plans to try a new tube to siphon oil from the gushing well. The markets, however, don't seem confident in either strategy: BP is trading at its lowest since July, says Business Week. Click here for the latest on the Gulf spill.
