More than 75 percent of Gulf oil cut off for storm: Financial News - Yahoo! Finance "NEW ORLEANS (AP) -- More than three-quarters of the Gulf of Mexico's offshore oil production had been cut off Saturday as energy companies evacuated petroleum platforms in the face of Hurricane Gustav. The federal Minerals Management Service, which manages offshore leases, said 76.8 percent of the Gulf's daily oil production of 1.3 million barrels, or 998,000, had been stopped ... The Gulf produces roughly 25 percent of the nation's oil and 15 percent of its natural gas." The figure at the bottom is a little odd though. In the US, we consume about 20 million barrels of oil a day, about 12 million of it is imported.
