Petroleum is a occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation using a fractionating column. It consists of occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds; the name petroleum covers both occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has been recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, reservoir characterisation have been completed, it is refined and separated, most by distillation, into numerous consumer products, from gasoline and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals.

Petroleum is used in manufacturing a wide variety of materials, it is estimated that the world consumes about 95 million barrels each day. The use of petroleum as fuel causes global ocean acidification. According to the UN's Intergovernmental Panel on Climate Change, without fossil fuel phase-out, including petroleum, there will be "severe and irreversible impacts for people and ecosystems"; the word petroleum comes from Medieval Latin petroleum, which comes from Latin petra', "rock", Latin oleum, "oil". The term was used in the treatise De Natura Fossilium, published in 1546 by the German mineralogist Georg Bauer known as Georgius Agricola. In the 19th century, the term petroleum was used to refer to mineral oils produced by distillation from mined organic solids such as cannel coal and refined oils produced from them. Petroleum, in one form or another, has been used since ancient times, is now important across society, including in economy and technology; the rise in importance was due to the invention of the internal combustion engine, the rise in commercial aviation, the importance of petroleum to industrial organic chemistry the synthesis of plastics, solvents and pesticides.

More than 4000 years ago, according to Herodotus and Diodorus Siculus, asphalt was used in the construction of the walls and towers of Babylon. Great quantities of it were found on the banks of the river Issus, one of the tributaries of the Euphrates. Ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society; the use of petroleum in ancient China dates back to more than 2000 years ago. In I Ching, one of the earliest Chinese writings cites that oil in its raw state, without refining, was first discovered and used in China in the first century BCE. In addition, the Chinese were the first to record the use of petroleum as fuel as early as the fourth century BCE. By 347 AD, oil was produced from bamboo-drilled wells in China. Crude oil was distilled by Persian chemists, with clear descriptions given in Arabic handbooks such as those of Muhammad ibn Zakarīya Rāzi; the streets of Baghdad were paved with tar, derived from petroleum that became accessible from natural fields in the region.

In the 9th century, oil fields were exploited in the area around Azerbaijan. These fields were described by the Arab geographer Abu al-Hasan'Alī al-Mas'ūdī in the 10th century, by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Arab and Persian chemists distilled crude oil in order to produce flammable products for military purposes. Through Islamic Spain, distillation became available in Western Europe by the 12th century, it has been present in Romania since the 13th century, being recorded as păcură. Early British explorers to Myanmar documented a flourishing oil extraction industry based in Yenangyaung that, in 1795, had hundreds of hand-dug wells under production. Pechelbronn is said to be the first European site where petroleum has been used; the still active Erdpechquelle, a spring where petroleum appears mixed with water has been used since 1498, notably for medical purposes. Oil sands have been mined since the 18th century. In Wietze in lower Saxony, natural asphalt/bitumen has been explored since the 18th century.

Both in Pechelbronn as in the coal industry dominated the petroleum technologies. Chemist James Young noticed a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a more viscous oil suitable for lubricating machinery. In 1848, Young set up a small business refining the crude oil. Young succeeded, by distilling cannel coal at a low heat, in creating a fluid resembling petroleum, which when treated in the same way as the seep oil gave similar products. Young found that by slow distillation he could obtain a number of useful
