Definitions
Barrel (petroleum): A unit of volume equal to 42 U. S. gallons.
Crude Oil (Including Lease Condensate): A mixture of hydrocar-
bons that exists in liquid phase in underground reservoirs and remains
liquid at atmospheric pressure after passing through surface separating
facilities. Included are lease condensate and liquid hydrocarbons pro-
duced from tar sands, gilsonite, and oil shale. Drip gases are also
included, but topped crude oil (residual oil) and other unfinished oils are
excluded. Where identifiable, liquids produced at natural gas processing
plants and mixed with crude oil are likewise excluded.
Crude Oil Refinery Input: The total crude oil put into processing
units at refineries.
Crude Oil Stocks: Stocks of crude oil and lease condensate held at
refineries, in pipelines, at pipeline terminals, and on leases.
perature is the mean of the maximum and minimum temperatures for
a 24- hour period.
Distillate Fuel Oil: A general classification for one of the petroleum
fractions produced in conventional distillation operations. Included
are products known as No. 1, No. 2, and No. 4 fuel oils and No. 1, No.
2, and No. 4 diesel fuels. It is used primarily for space heating, on- and
off- highway diesel engine fuel (including railroad engine fuel and fuel
for agricultural machinery), and electric power generation.
Motor Gasoline: A complex mixture of relatively volatile hydro-
carbons, with or without small quantities of additives, obtained by
blending appropriate refinery streams to form a fuel suitable for use
in spark- ignition engines. Motor gasoline includes both leaded and
unleaded grades of finished motor gasoline, blending components, and
gasohol.
Natural Gas Plant Liquids (NGPL): Natural gas liquids recovered
from natural gas in processing plants and, in some situations, from
natural gas field facilities, as well as those extracted by fractionators.
Natural gas plant liquids are defined according to the published speci-
fications of the Gas Processors Association and the American Society
for Testing and Materials as follows: ethane, propane, normal butane,
isobutane, pentanes plus, and other products from natural gas process-
ing plants (i. e., products meeting the standards for finished petroleum
products produced at natural gas processing plants, such as finished
motor gasoline, finished aviation gasoline, special naphthas, kerosene,
distillate fuel oil, and miscellaneous products).
Offshore: That geographic area that lies seaward of the coastline. In
general, the coastline is the line of ordinary low water along with that
portion of the coast that is in direct contact with the open sea or the
line marking the seaward limit of inland water.
Oil Well: A well completed for the production of crude oil from one
or more oil zones or reservoirs. Wells producing both crude oil and
natural gas are classified as oil wells.
Operable Refineries: Refineries that were in one of the following
three categories at the beginning of a given year: in operation; not in
operation and not under active repair, but capable of being placed into
operation within 30 days; or not in operation, but under active repair
that could be completed within 90 days.
Proved Reserves, Crude Oil: The estimated quantities of all liquids
defined as crude oil that geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from
known reservoirs under existing economic and operating conditions.
Refinery Input: The raw materials and intermediate materials proc-
essed at refineries to produce finished petroleum products. They include
crude oil, products of natural gas processing plants, unfinished oils, other
hydrocarbons and alcohol, motor gasoline and aviation gasoline blending
components, and finished petroleum products.
Refinery Output: The total amount of petroleum products produced
at a refinery. Includes petroleum consumed by the refinery.
Refinery (petroleum): An installation that manufactures finished
petroleum products from crude oil, unfinished oils, natural gas liquids,
other hydrocarbons, and alcohol.
Residual Fuel Oil: The heavier oils that remain after the distillate
fuel oils and lighter hydrocarbons are distilled away in refinery opera-
tions and that conform to ASTM Specifications D396 and D975.
Included are No. 5, a residual fuel oil of medium viscosity; Navy Spe-
cial, for use in steam- powered vessels in government service and in
shore power plants; and No. 6, which includes Bunker C fuel oil and
is used for commercial and industrial heating, for electricity genera-
tion, and to power ships. Imports of residual fuel oil include imported
crude oil burned as fuel.
Strategic Petroleum Reserve (SPR): Petroleum stocks maintained
by the Federal Government for use during periods of major supply in-
terruption.
