McGee Corp. reported Friday they evacuated some workers but were not cutting production in the eastern gulf. Thursday, BP Plc and Shell Oil also evacuated workers but kept production going. "If the storm takes a more westerly track" Murphy may decide to alter its plans, said company spokeswoman Mindy West. About 25 percent of domestic U.S. production of natural gas and crude oil comes from offshore operations in the gulf. Offshore production capacity is 1.5 million barrels per day of crude and 10 billion cubic feet per day of natural gas.
