  2. Abiogenic petroleum origin - Wikipedia

    en.wikipedia.org/wiki/Abiogenic_petroleum_origin

    [2] [3] Mainstream theories about the formation of hydrocarbons on earth point to an origin from the decomposition of long-dead organisms, though the existence of hydrocarbons on extraterrestrial bodies like Saturn's moon Titan indicates that hydrocarbons are sometimes naturally produced by inorganic means. A historical overview of theories of ...

  3. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    The use of geochemistry is relatively cost-effective that allows geologists to assess reservoir-related issues. Once oil to source rock correlation is found, petroleum geologists will use this information to render a 3D model of the basin. Now they can assess the timing of generation, migration, and accumulation relative to the trap formation.

  4. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    Fossil fuel divestment or fossil fuel divestment and investment in climate solutions is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels.

  5. Extraction of petroleum - Wikipedia

    en.wikipedia.org/wiki/Extraction_of_petroleum

    Petroleum is a fossil fuel that can be drawn from beneath the Earth's surface. 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.

  6. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Syngas is combustible and can be used as a fuel. [ 2 ] [ 3 ] [ 4 ] Historically, it has been used as a replacement for gasoline , when gasoline supply has been limited; for example, wood gas was used to power cars in Europe during WWII (in Germany alone half a million cars were built or rebuilt to run on wood gas).

  7. Geochemistry of carbon - Wikipedia

    en.wikipedia.org/wiki/Geochemistry_of_carbon

    Yet it is the twelfth most common element there. In the rock of the lithosphere, carbon commonly occurs as carbonate minerals containing calcium or magnesium. It is also found as fossil fuels in coal and petroleum and gas. Native forms of carbon are much rarer, requiring pressure to form. Pure carbon exists as graphite or diamond. [1]

  8. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    Sediments, including fossil fuels, freshwater systems, and non-living organic material. Earth's interior (mantle and crust). These carbon stores interact with the other components through geological processes. The carbon exchanges between reservoirs occur as the result of various chemical, physical, geological, and biological processes.

  9. Suess effect - Wikipedia

    en.wikipedia.org/wiki/Suess_effect

    The Suess effect is a change in the ratio of the atmospheric concentrations of heavy isotopes of carbon (13 C and 14 C) by the admixture of large amounts of fossil-fuel derived CO 2, which contains no 14 CO 2 and is depleted in 13 CO 2 relative to CO 2 in the atmosphere and carbon in the upper ocean and the terrestrial biosphere .
