Key Terms Definition
Crude Oil A mixture of hydrocarbons that exists in liquid phase in natural underground reservoirs and remains liquid at atmospheric pressure after passing through surface separating facilities. Depending upon the characteristics of the crude stream, it may also include:
  • Small amounts of hydrocarbons that exist in gaseous phase in natural underground reservoirs but are liquid at atmospheric pressure after being recovered from oil well (casinghead) gas in lease separators and are subsequently commingled with the crude stream without being separately measured. Lease condensate recovered as a liquid from natural gas wells in lease or field separation facilities and later mixed into the crude stream is also included;
  • Small amounts of nonhydrocarbons produced with the oil, such as sulfur and various metals;
  • Drip gases, and liquid hydrocarbons produced from tar sands, oil sands, gilsonite, and oil shale.

  • Liquids produced at natural gas processing plants are excluded. Crude oil is refined to produce a wide array of petroleum products, including heating oils; gasoline, diesel and jet fuels; lubricants; asphalt; ethane, propane, and butane; and many other products used for their energy or chemical content.
    F.O.B. Price (Free on Board) The price actually charged at the producing country's port of loading. The reported price includes deductions for any rebates and discounts or additions of premiums where applicable and should be the actual price paid with no adjustment for credit terms.
    Imported Crude oil produced outside the U.S. and brought into the U.S.

  •   Explanatory Notes

  • Values shown for the current two months are preliminary. Values shown for the previous two months may be revised to account for late submissions and corrections. Final revisions to monthly and annual values are available upon publication of the June Petroleum Marketing Monthly. Annual averages that precede the release of the June Petroleum Marketing Monthly are calculated from monthly data. Data through 2023 are final.
  • Values through 1980 reflect the month of reporting; values since then reflect the month of acquisition, which can be the month of loading, the month of landing, or something between those events. Prices for crude oil can be determined at a time other than the acquisition date (additional details).
  • For purposes of this survey, the United States includes the 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, and all American territories and possessions.
  • Data for Ecuador is included in Total OPEC for 1973-1992 and 2008-April 2020 (OPEC member 1973-1992 and November 2007-2019).
