the ocean. Leasing California state seabed is controlled by the State Lands Commission, which halted further leasing of state offshore tracts after the Santa Barbara oil spill in 1969. In 1994 the California legislature codified the ban on new leases by passing the California Coastal Sanctuary Act, which prohibited new leasing of state offshore tracts. The federal government has had no new lease sales for offshore California since 1982. Offshore drilling has continued from existing platforms in state and federal waters. State offshore seabed in California produced of oil per day, and federal offshore tracts produced of oil per day in November 2008. State and federal offshore tracts together made up 16% of the state's oil production. Notable offshore fields include the Ellwood Oil Field, which is partially onshore and partially offshore, and the Dos Cuadras Field, source of the 1969 spill, which is entirely within the federal zone. Gulf of Mexico See Offshore oil and gas in the US Gulf of Mexico The western and central Gulf of Mexico, which includes offshore Texas, Louisiana, Mississippi, and Alabama, is one of the major petroleum-producing areas of the United States. In 2007, federal leases in the western and central Gulf of Mexico produced 25% of the nation's oil and 14% of the nation's natural gas. In 2008, federal leases in the Gulf of Mexico produced of oil, down from in 2002; however, due to new deep-water discoveries, the MMS projects that oil production from the Gulf of Mexico will increase to per year by 2013. Major fields include Atlantis Oil Field, and the Tiber oilfield (discovered 2009) and others in the Keathley Canyon protraction area. Notable oil platforms include Baldpate, Bullwinkle, Mad Dog, Magnolia, Mars, Petronius, and Thunder Horse. Notable individual wells include Jack 2 and Knotty Head. The eastern Gulf of Mexico, which includes offshore Gulf Coast Florida, has never been a petroleum-producing area due to federal and state restrictions on exploration. Offshore platforms currently exist as far east as to near the Florida-Alabama border. East Coast See Offshore drilling on the US Atlantic coast In the late 1970s and early 1980s oil companies drilled 51 exploratory wells on federal leases on the outer continental shelf of the Atlantic coast. All the leases have now reverted to the government. A 1996 study by the MMS estimated undiscovered conventionally recoverable resources in Atlantic federal waters to be of oil and gas.
