This section describes (1) the federal oil and gas fiscal system, (2) leasing processes, and (3) the history of oil and gas management challenges. Created by Congress in 1849, Interior oversees the nation's publicly owned natural resources including parks, wildlife habitat, and crude oil and natural gas resources on millions of acres onshore and offshore in the waters of the outer continental shelf. With regard to oil and gas in particular, Interior leases federal lands and waters (also referred to as submerged lands), issues permits for oil and gas drilling, and is responsible for ensuring that the federal government receives payment from the private companies that extract oil and gas from federal leases.
