Sunken oil rig off Louisiana coast may form huge oil slick

The Associated Press and The Los Angeles Times report:


PORT FOURCHON, La. – As the odds of survival for 11 missing workers diminished Thursday, officials warned that the dramatic explosion and fire that sank an oil rig off the Louisiana coast may pose a serious environmental threat if oil is leaking thousands of feet below the surface.

An oil slick was already forming Wednesday as the Deepwater Horizon oil rig burned in the Gulf of Mexico, about 50 miles southeast of Venice, La. The Deepwater Horizon, the $600 million mobile offshore rig that burned for more than a day before sinking Thursday, could spill up to 336,000 gallons of crude a day into the water.
