| 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.

| Imported |
Crude oil produced outside the U.S. and brought into the U.S.
|
| Landed Cost |
The dollar per barrel price of crude oil at the port of discharge. Includes charges
associated with the purchase, transportation, and insuring of a cargo from the purchase
point to the port of discharge. Does not include charges incurred at the discharge port
(e.g., import tariffs or fees, wharfage charges, and demurrage).

| OPEC |
An intergovernmental organization whose stated objective is to coordinate and
unify petroleum policies among member countries. It was created at the Baghdad
Conference on September 10-14, 1960, by Iran, Iraq, Kuwait, Saudi Arabia, and
Venezuela. The five founding members were later joined by nine other members:
Qatar (1961); Indonesia (1962); Libya (1962); United Arab Emirates (1967);
Algeria (1969); Nigeria (1971); Ecuador (1973-1992, 2007); Gabon (1975-1994),
and Angola (2007).

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
Petroleum Marketing Annual.
Annual averages that precede the release of the Petroleum Marketing Annual are
calculated from monthly data published in the
Petroleum Marketing Monthly.

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).
