, is one of the major petroleum-producing areas of the United States. Oil production from US federal waters in the Gulf of Mexico reached an all-time annual high of 1.65 million barrels per day in 2017. Oil production is expected to continue the upward trend in 2018 and 2019, based on ten new oil fields which are planned to start production in those years. According to the Energy Information Administration, "Gulf of Mexico federal offshore oil production accounts for 15% of total U.S.

As technology has progressed over the years, oil companies have extended drilling and production farther and farther from shore, and into deeper and deeper waters. In 1937 Superior Oil of California and Pure Oil constructed a platform just over a mile from the shore at a depth of 13 feet. A year later, Humble Oil built a mile-long wooden trestle with railway tracks into the sea at McFadden Beach on the Gulf of Mexico, placing a derrick at its end - this was later destroyed by a hurricane. A platform was installed in a hundred feet of water for the first time in 1955; in two hundred feet of water in 1962; and in a thousand feet of water in 1979. "By 1970, the technology existed to drill in 2,000 feet of water and actual exploratory drilling was taking place at 1,400 feet." By 2009, more than 70% of Gulf of Mexico oil production came from wells drilled in depths greater than , almost double from the percentage ten years ago.
The deepest water depth in which a discovery has been made is , at Lloyd Ridge 370 (Diamond).

announced plans to allow drilling in the eastern Gulf of Mexico, in federal waters greater than from the coasts of Alabama and Florida. In December 2010, following the ''Deepwater Horizon'' oil spill, the Obama administration reversed its plans to open the eastern Gulf, and imposed a moratorium on new drilling in the eastern Gulf of Mexico for at least seven years.
In April 2016, the US Bureau of Safety and Environmental Enforcement (BSEE) issued final well control regulations to improve the effectiveness of offshore safety.
In November 2021, the Department of Interior’s Bureau of Ocean Energy Management made available for auction, for the purpose of oil and gas production, about 80.9 million acres in federal lands located offshore in the Gulf of Mexico. These 80 million acres of available tracts represented the largest ever lease of oil and gas drilling leases in the United States. Of the 80 million acres up for auction, 1.7 million acres of drilling rights sold. The sales generated about $191 million in revenue for the government. Chevron was the largest buyer, spending $47.1 million, followed by Anadarko, BP, Royal Dutch Shell, and Exxon. Exxon's spending of $14.9 million represented the largest sale by acreage, including 94 shallow water tracts. For context, in January 2021, the new administration in the United States paused most new oil and gas leases on federal land. In response, a federal court in Louisiana issued an order in June 2021 that prompted the Biden administration to conduct the auction, but it was later determined that the order did not require the auction to be held. The timing was such that the auction was held about a week after the conclusion of a group of worldwide environmental talks known as

In 2012, federal leases in the Gulf of Mexico produced of oil, which made up 19.5% of all U.S. oil production that year, and more than that of any U.S. state other than Texas. The 2012 production was less than the in 2009; however, due to new deep-water discoveries, the U.S.

The first federal lease sale offshore Florida was in 1959. In the 1980s the state of Florida objected to further federal lease sales in offshore Florida, and the last one was held in 1985. Because of state objections, the federal government agreed to pay $200 million to nine oil companies to buy back leases south of 26 degrees north latitude.

in the south. The lease, which now belongs to Coastal Petroleum, was renegotiated in 1975 to leave Coastal with partial rights from from the shore, and full rights to state waters from from the shore. Florida has since banned offshore drilling in state waters, and has a long-running legal dispute with Coastal over Coastal's efforts to drill the offshore lease.
Florida banned drilling in state waters in 1992, and has also opposed additional drilling in federal waters off Florida. However, in April 2009 three committees of the Florida House of Representatives approved a bill that would allow offshore drilling in state waters more than from shore. Because state waters extend only from shore on the east coast of Florida, the legislation would have affected only state waters on the Gulf coast of the state, where state waters extend out to from shore. The bill passed the Florida House in April 2009, but died soon after in the Florida Senate.
