Obama to Suspend Deepwater Oil Drilling VOA News 27 May 2010 President Barack Obama walks on the South Lawn of the White House following a trip to California, 26 May 2010 Photo: AP President Barack Obama walks on the South Lawn of the White House following a trip to California, 26 May 2010 [1]Listen to President Obama's Press Conference LIVE on VOANews.com at 12:45 p.m. EDT 1645 UTC U.S. President Barack Obama is expected to announce Thursday he is extending a ban on new deepwater oil drilling projects because of the disastrous oil leak in the Gulf of Mexico. The six-month extension follows a safety review Mr. Obama ordered after an oil rig exploded in the Gulf on April 20, killing 11 workers and rupturing an undersea well. The move will also suspend applications for Arctic oil drilling off the coast of Alaska. Also Thursday, U.S. government scientists announced new estimates that the well has been leaking between 12,000 and 25,000 barrels of oil into the Gulf every day. The figures are much higher than initial estimates of 5,000 barrels per day. Energy company BP is currently trying to stop the well with a procedure called a "top kill." It involves pumping a mixture of heavy fluids into the well to combat the leak, then using cement to seal it off. The "top kill" procedure is difficult because of the depth of the well -- 1,500 meters below the surface. Frustration with BP and the government's response has risen as oil washes up on southern coastlines, endangering wildlife and the commercial fishing industry. U.S. officials have closed 20 percent of federal fishing grounds in the Gulf of Mexico as a result of the spill. Fishermen in the state of Louisiana are pressing BP to compensate them for the losses to their businesses.  Some information for this report was provided by AP, AFP and Reuters.
