Nov. 26 (Bloomberg) -- The U.S. government said 60 of about 3,800 oil and natural-gas production platforms in the Gulf of Mexico were destroyed by hurricanes Gustav and Ike.

The platforms were capable of producing 13,657 barrels of oil and 96.5 million cubic feet of natural gas a day, the U.S. Minerals Management Service said in an e-mailed statement today. An additional 31 platforms damaged by the storms may take three to six months to repair, the agency said in its final planned assessment of the impact of the hurricanes.

The Minerals Management Service, part of the U.S. Interior Department, previously said 49 platforms were destroyed by the storms.

Rigs in the U.S. Gulf normally produce about 1.3 million barrels of oil a day and 7.4 billion cubic feet of gas.

Hurricane Ike made landfall on the Gulf Coast of Texas Sept. 13, less than two weeks after Hurricane Gustav struck the Louisiana coast.
