Rock oil, mineral oil, or natural oil, a dark brown or greenish inflammable liquid, which, at certain points, exists in the upper strata of the earth, from whence it is pumped, or forced by pressure of the gas attending it. It consists of a complex mixture of various hydrocarbons, largely of the methane series, but may vary much in appearance, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc.
A naturally occurring, oily, flammable liquid composed principally of hydrocarbons. Crude oil is occasionally found in springs or pools but usually is drilled from wells beneath the earth's surface. Petroleum products are obtained from the processing of crude oil, natural gas and other hydrocarbon compounds. Petroleum products include unfinished oils, liquefied petroleum gases, pentanes plus, aviation gasoline, motor gasoline, naphtha-type jet fuel, kerosene-type jet fuel, kerosene, distillate fuel oil, residual fuel oil, petrochemical feedstocks, special naphtha's, lubricants, waxes, petroleum coke, asphalt, road oil, still gas, and miscellaneous products.
Crude oil and any products derived from crude oil that are liquids at normal temperature and pressure, eg motor fuel, jet oil, and lubricants.
Generic name of hydrocarbons, including oil, crude oil, natural gas, natural gas liquids and their refined products.
A mixture of hydrocarbons existing in the liquid state found in natural underground reservoirs often associated with gas. Petroleum includes fuel oil No. 2, No. 4, No. 5, No. 6; topped crude; kerosene; and jet fuel.
a thick, oily liquid found below the Earth's surface. It is used to make gasoline, kerosene, heating oil, and many other products.
(pe-tro'-le-um) A naturally occurring complex liquid hydrocarbon, that after distillation and removal of impurities, yields a range of combustible fuels, petrochemicals, and lubricants.
Strictly speaking, crude oil. Also used to refer to all hydrocarbons, including oil, natural gas, natural gas liquids, and related products.
Black organic liquid which is processed to make fuel, lubricants and various petrochemicals.
a natural mixture of organic compounds found in liquid form; liquid fossil fuel composed mainly of hydrocarbons, but also containing compounds of nitrogen, sulfur, and oxygen, along with small amounts of metal-containing compounds.
an oily flammable liquid from oil wells drilled in the ground, refined into gasoline, kerosene and other products.
Oil or gas obtained from the rocks of the earth.
An oily liquid that can be pumped from the Earth and used to make items like plastic and gasoline.
Naturally occurring mineral oil consisting predominately of hydrocarbons.
n: a substance occurring naturally in the earth in solid, liquid, or gaseous state and composed mainly of mixtures of chemical compounds of carbon and hydrogen, with or without other nonmetallic elements such as sulfur, oxygen, and nitrogen. In some cases, especially in the measurement of oil and gas, petroleum refers only to oil—a liquid hydrocarbon—and does not include natural gas or gas liquids such as propane and butane.
The discovery of offshore oil in Angola has and will have a huge impact on the country. Foreign companies, including Exxon and Texaco, have developed oil drilling in the country. Currently, oil accounts for 90 percent of the country's GDP. It is ranked third behind Saudi Arabia and Iran in known oil reserves. Oil money provided funding for the government during the civil war, but will also be a significant factor during the rebuilding of the country. The country must learn to use its money wisely and to expand its economy so as not to be too dependent on its oil production.
A generic term applied to oil and oil products in all forms. Examples include crude oil, lease condensate, unfinished oil, refined petroleum products, and natural gas plant liquids.
A thick, flammable, yellow-to-black mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally beneath the earth's surface, can be separated into fractions including natural gas, gasoline, naphtha, kerosene, fuel and lubricating oils, paraffin wax, and asphalt and is used as raw material for a wide variety of derivative products.
crude oil found in rock. A wide variety of commercially important petrochemicals, such as gasoline and kerosene are derived from it.
A thick, dark, flammable liquid that occurs naturally beneath the Earth and is processed into such products as natural gas, gasoline, kerosene, and fuel oils.
Any of a group of naturally occurring substances made up of hydrocarbons. These substances may be gaseous, liquid, or semi-solid.
a dark oil consisting mainly of hydrocarbons
another word for crude oil, it is a liquid hydrocarbon mixture found underground that can be refined into useful products like gasoline and motor oils.
a fossil fuel extracted from natural deposits deep in the Earth; consists of a mixture of solids, liquids, and gases that are physically separated (refined) into products such as gasoline, wax, asphalt, and petrochemical feedstocks, which are the building blocks of many plastics. Also sometimes known as oil (crude oil).
Refers to a range of substances composed primarily of carbon and hydrogen that are found in rock. The word derives from the Latin words petra for rock and oleum for oil and literally means "rock oil." Although petroleum can be found in solid or gaseous form, the term usually refers to liquid forms of crude oil and natural gas.
a smell analagous to the semi-refined oil product. Can be traced to sources of contamination in wine storage containers or even the fuel used in pots to prevent frost damage to the vines and their fruit.
Crude oil. Naturally occurring liquid hydrocarbons from which gasoline, kerosene, and countless other 'petrochemicals' are produced. Non-hydrocarbon compounds (often containing sulfur and nitrogen) may also be present. In the broadest sense, petroleum refers to all naturally occurring hydrocarbons including oil, natural gas, condensate and their derived products.
A complex liquid mixture of hydrocarbons, oily and inflammable in character
Crude oil or any fraction of crude oil that is liquid at standard temperature and pressure (60° Fahrenheit and 14.7 pounds per square inch absolute). UST Rule 1200-1-15-.01(3)
A natural mixture of hydrocarbons in gaseous, liquid, or solid form.
Generic term for all forms of oil and oil products, including crude oil, natural gas liquids and unfinished oils.
A generic term applied to oil and oil products in all forms, such as crude oil, lease condensate, unfinished oils, refined petroleum products, natural gas plant liquids, and non-hydrocarbon compounds blended into finished petroleum products. A mixture of hydrocarbons existing in the liquid state found in natural underground reservoirs often associated with gas.
A general term for solid, liquid or gaseous hydrocarbons.
a thick, dark liquid composed mostly of hydrocarbon compounds. pH scale a log scale based on 10 and equal to 2log[H1]; a convenient way to represent solution acidity.
A generic name for hydrocarbons, including crude oil, natural gas liquids, natural gas and their products.
Mixture of hydrocarbons with similar properties as mineral oil. Industrially it is used as a grease component. (Example: Vaseline is a petroleum jelly.)
See crude oil.
Oil and natural gas; crude oil.

Petroleum (from Latin petra â€“ rock and Greek oleum â€“ oil) or crude oil is a naturally occurring liquid found in formations in the Earth consisting of a complex mixture of hydrocarbons (mostly alkanes) of various lengths. In its naturally occurring form, it may contain other nonmetallic elements such as sulfur, oxygen, and nitrogen. Manual of Petroleum Measurement Standards (MPMS), by the American Petroleum Institute It is usually black or dark brown (although it may be yellowish or even greenish) but varies greatly in appearance, depending on its composition.
