  2. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Halogenating a hydrocarbon produces something that is not a hydrocarbon. It is a very common and useful process. Hydrocarbons with the same molecular formula but different structural formulae are called structural isomers. [1]: 625 As given in the example of 3-methylhexane and its higher homologues, branched hydrocarbons can be chiral.

  3. Petroleum - Wikipedia

    en.wikipedia.org/wiki/Petroleum

    Petroleum is used mostly, by volume, for refining into fuel oil and gasoline, both important primary energy sources. 84% by volume of the hydrocarbons present in petroleum is converted into fuels, including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas.

  4. Formation evaluation - Wikipedia

    en.wikipedia.org/wiki/Formation_evaluation

    Two techniques commonly used at present. The first is the "whole core", a cylinder of rock, usually about 3" to 4" in diameter and up to 50 to 60 feet (15 to 18 m) long. It is cut with a "core barrel", a hollow pipe tipped with a ring-shaped diamond chip-studded bit that can cut a plug and bring it to the surface.

  5. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    Some of the key disciplines used in reservoir analysis are the fields of structural analysis, stratigraphy, sedimentology, and reservoir engineering. The seal, or cap rock, is a unit with low permeability that impedes the escape of hydrocarbons from the reservoir rock. Common seals include evaporites, chalks and shales. Analysis of seals ...

  6. Natural gas - Wikipedia

    en.wikipedia.org/wiki/Natural_gas

    Natural gas is primarily used in the northern hemisphere. North America and Europe are major consumers. Often well head gases require removal of various hydrocarbon molecules contained within the gas. Some of these gases include heptane, pentane, propane and other hydrocarbons with molecular weights above methane (CH 4). The natural gas ...

  7. 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 ...

  8. Liquid fuel - Wikipedia

    en.wikipedia.org/wiki/Liquid_fuel

    Gasoline is the most widely used liquid fuel. Gasoline, as it is known in United States and Canada, or petrol virtually everywhere else, is made of hydrocarbon molecules (compounds that contain hydrogen and carbon only) forming aliphatic compounds, or chains of carbons with hydrogen atoms attached.

  9. Source rock - Wikipedia

    en.wikipedia.org/wiki/Source_rock

    Source rocks are classified from the types of kerogen that they contain, which in turn governs the type of hydrocarbons that will be generated: [1]. Type I source rocks are formed from algal remains deposited under anoxic conditions in deep lakes: they tend to generate waxy crude oils when submitted to thermal stress during deep burial.
