BP says it is investigating the potential source of a "sheen" observed in the Gulf of Mexico by the U.S. Coast Guard last week, but added there was no immediate indication it was the result of a new oil spill. BP says it has no existing operations near the sheen, but does have two abandoned exploration well sites in the area.
