Crude oil, or petroleum, is recovered mostly through oil drilling. This comes after the studies of geology, sedimentary basin analysis, reservoir characterisation, and it is then 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.
Let's have a look at how the black gold is extracted and refined.

Other geographic regions' consumption patterns are as follows: South and Central America (44 per cent), Africa (41 per cent), and North America (40 per cent).
The world consumes 30 billion barrels of oil per year, with developed nations being the largest consumers.

Governments such as the United States government provide a heavy public subsidy to petroleum companies, with major tax breaks at virtually every stage of oil exploration and extraction, including for the costs of oil field leases and drilling equipment.

Imperial Russia produced 3,500 tonnes of oil in 1825 and doubled its output by mid-century. After oil drilling began in what is now Azerbaijan in 1848, two large pipelines were built in the Russian Empire: the 833km long pipeline to transport oil from the Caspian to the Black Sea port of Batumi (Baku-Batumi pipeline), completed in 1906, and the 162km long pipeline to carry oil from Chechnya to the Caspian.

At the turn of the 20th century, Imperial Russia's output of oil, almost entirely from the Apsheron Peninsula, accounted for half of the world's production and dominated international markets.

Nearly 200 small refineries operated in the suburbs of Baku by 1884. As a side effect of these early developments, the Apsheron Peninsula emerged as the world's "oldest legacy of oil pollution and environmental negligence".

The first modern oil refineries were built by Ignacy Lukasiewicz near Jaslo (then in the dependent Kingdom of Galicia and Lodomeria in Central European Galicia), Poland from 1854-56.

These were initially small as demand for refined fuel was limited. The refined products were used in artificial asphalt, machine oil and lubricants, in addition to Lukasiewicz's kerosene lamp.
As kerosene lamps gained popularity, the refining industry grew in the area.

In the first quarter of the 20th century, the United States overtook Russia as the world's largest oil producer.
By the 1920s, oil fields had been established in many countries including Canada, Poland, Sweden, the Ukraine, the United States, Peru and Venezuela.

The petroleum industry generally classifies crude oil by the geographic location it is produced in (e.g. West Texas Intermediate, Brent, or Oman), its API gravity (an oil industry measure of density), and its sulfur content.
Crude oil may be considered light if it has low density or heavy if it has high density; and it may be referred to as sweet if it contains relatively little sulfur or sour if it contains substantial amounts of sulfur.

The geographic location is important because it affects transportation costs to the refinery.
Light crude oil is more desirable than heavy oil since it produces a higher yield of petrol, while sweet oil commands a higher price than sour oil because it has fewer environmental problems and requires less refining to meet sulfur standards imposed on fuels in consuming countries.
