BP Oil Well Cap Holds as Scientists Analyze Test Results VOA News 17 July 2010 National Incident Commander Ret. Coast Guard Adm. Thad Allen briefs reporters 8 Jul 2010 Photo: AP National Incident Commander Ret. Coast Guard Adm. Thad Allen (file photo) Oil company BP says the giant cap it placed over a blown-out well appears to be holding, as engineers work around the clock to analyze pressure readings, temperature gauges and underwater images.  The U.S. official overseeing the government's response to the Gulf of Mexico oil spill said Friday pressure tests on the ruptured well will continue, as initial readings were not conclusive.  Retired Coast Guard Admiral Thad Allen said pressure readings, while rising slowly, have not reached the level that would show there are no new leaks in the well.  He said the readings could signal a depletion in the reservoir that is the source of the oil, or that there may be a leak that has not been discovered. BP executive Kent Wells said later there is no indication any oil is leaking.   On Thursday, BP choked off the oil leak with a new seal and containment cap for the first time since the disaster started in April.  President Barack Obama said BP's capping of the oil spill is good news, but he cautioned that it is not yet clear if the cap will stay in place and permanently stop the flow. He said the final solution to the problem is completion of relief wells. Government estimates say as much as 60,000 barrels of oil per day were escaping into the Gulf of Mexico. Mr. Obama has faced criticism that his administration was slow to respond to the initial explosion of the BP-leased Deepwater Horizon oil rig on April 20. The blast killed 11 crewmen and triggered the leak that has spewed millions of barrels of oil into the Gulf. The oil spill is the worst in U.S. history. The disaster has devastated fragile communities and ecosystems along the Gulf, hurting local economies and jobs.
