    en.wikipedia.org/wiki/Abiogenic_petroleum_origin

    The "deep biotic petroleum hypothesis", similar to the abiogenic petroleum origin hypothesis, holds that not all petroleum deposits within the Earth's rocks can be explained purely according to the orthodox view of petroleum geology. Thomas Gold used the term "the deep hot biosphere" to describe the microbes which live underground. [6]

    Oil field in California, 1938. The modern history of petroleum began in the nineteenth century with the refining of paraffin from crude oil. The Scottish chemist James Young in 1847 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 thicker oil suitable for ...

  8. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    Reservoirs of petroleum are formed through the mixture of plants, algae, and sediments in shallow seas under high pressure. Petroleum is mostly recovered from oil drilling. Seismic surveys and other methods are used to locate oil reservoirs. Oil rigs and oil platforms are used to drill long holes into the earth to create an oil well and extract ...
