Much remains unknown about the fate of refineries that stretch from Alabama through Louisiana and into Texas, which collectively account for about half of the nation's oil-processing capacity. As of Monday morning, the storm had shut 12 refineries and slowed production at 10 more, representing a loss of more than 10% of U.S. gasoline production.
"This hurricane event is not over yet . . . and you had a wide swath of area that lost power," said Andrew Lipow, a Houston-based consultant. Long power outages could cripple big refineries as well as the pipeline pumps that send fuel to the Northeast and other regions -- a big problem after Katrina.
