Where Oil Is Produced
U.S. Crude Oil Production
U.S. crude oil production peaked in 1970 and has declined gradually since then. In 1970, domestic production of crude oil (including lease condensate¹) averaged 9.64 million barrels per day (MMbbl/d). In 2006, total U.S. domestic crude oil production, including Federal offshore, averaged 5.102 MMbbl/d, a decrease of about 47% from 1970.
The top six crude oil-producing States in 2006 (and their percent share of total domestic production) were Texas (21%), Alaska (15%), California (12%), Louisiana (4%), Oklahoma (3%), and New Mexico (3%). Production on Federal offshore-leases in the Gulf of Mexico in 2006 was 1.3 MMbbl/d, about 25% of total U.S. production.
World Crude Oil Production
Total world production of crude oil (including lease condensate, but excluding natural gas plant liquids²) in 2006 was 73.54 MMbbl/d (preliminary). The top five oil producing countries, which together accounted for about 43% of total world production, were: Russia (9.25 MMbbl/d), Saudi Arabia (9.15 MMbbl/d), the United States (5.1 MMbbl/d), Iran (4.03 MMbbl/d) and China (3.69 MMbbl/d). The Organization of Petroleum Exporting Countries (OPEC), which includes Saudi Arabia, produced 32.1 MMbbl/d or about 44% of the world total.
1. Lease Condensate: A mixture consisting primarily of pentanes and heavier hydrocarbons which is recovered as a liquid from natural gas in lease separation facilities.
