Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum. However, raw petroleum or crude oil has characteristic properties and composition.

There are four main types of hydrocarbons found in crude oil. The hydrocarbons primarily are alkanes, cycloalkanes, and aromatic hydrocarbons. Although there is considerable variation between the ratios of organic molecules, the elemental composition of petroleum is well-defined:

Written By: Crude oil, liquid petroleum that is found accumulated in various porous rock formations in Earth鈥檚 crust and is extracted for burning as fuel or for processing into chemical products. A summary treatment of crude oil follows. For full treatment, see petroleum, petroleum production, and petroleum refining.
