petroleum, crude oil, crude, rock oil, fossil oil, oil(noun)
a dark oil consisting mainly of hydrocarbons
A flammable liquid ranging in color from clear to very dark brown and black, consisting mainly of hydrocarbons, occurring naturally in deposits under earth surface.
Origin: From petroleum, from petra + oleum.
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
Origin: [NL., fr. L. petra a rock + oleum oil: cf. F. ptrole. Cf. Petrify, and Oil.]
Petroleum is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology, sedimentary basin analysis, reservoir characterization. It is refined and separated, most easily by boiling point, into a large number of consumer products, from petrol and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. Petroleum is used in manufacturing a wide variety of materials, and it is estimated that the world consumes about 90 million barrels each day.

The Nuttall Encyclopedia
is the common name of a series of rock oils found in large quantities in the United States and Canada, near Rangoon, and in the neighbourhood of the Caspian Sea. The oil issues from the rocks, or is drawn from subterranean reservoirs, where its presence is supposed to result from natural distillation of vegetable and animal substances, and after refining, put in the market as benzoline, paraffin, and lubricating oil. It is extensively used in the industries, and has been applied as fuel to steamships. Pétroleuse
U.S. National Library of Medicine
Naturally occurring complex liquid hydrocarbons which, after distillation, yield combustible fuels, petrochemicals, and lubricants.
Dictionary of Nautical Terms
Called also rock, mineral, or coal, oil. A natural oil widely distributed over the globe, consisting of carbon and hydrogen, in the proportion of about 88 and 12 per cent. It burns fiercely with a thick black smoke; and attempts, not yet successful, have been made to adapt it as a fuel for steamers.
