Gulf of Mexico Fact Sheet

The Gulf of Mexico area, both onshore and offshore, is one of the most important regions for energy resources and infrastructure. Gulf of Mexico federal offshore oil production accounts for 15% of total U.S. crude oil production and federal offshore natural gas production in the Gulf accounts for 5% of total U.S. dry production. Over 47% of total U.S. petroleum refining capacity is located along the Gulf coast, as well as 51% of total U.S. natural gas processing plant capacity.
