  2. Shale oil - Wikipedia

    en.wikipedia.org/wiki/Shale_oil

    Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock ( kerogen ) into synthetic oil and gas .

  3. Oil shale - Wikipedia

    en.wikipedia.org/wiki/Oil_shale

    Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as ...

  4. Shale oil extraction - Wikipedia

    en.wikipedia.org/wiki/Shale_oil_extraction

    Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen ...

    The shale drilling techniques that led to a boom in oil and gas output have also spurred the development of geothermal, which in theory could provide a stable source of power equal to the demand ...

  6. Oil shale industry - Wikipedia

    en.wikipedia.org/wiki/Oil_shale_industry

    The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured.

    The shale oil would then be pumped to the surface. The calculated recovery was 1.2 billion barrels over the project life. [51] [52] Chevron and Conoco joined in 1981 to start the Clear Creek Project, north of Debeque. The plan was to produce shale oil by underground mining and surface retorting.

  8. Oil shale reserves - Wikipedia

    en.wikipedia.org/wiki/Oil_shale_reserves

    Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales can be classified by their composition (carbonate minerals such as calcite or detrital minerals such as quartz and clays) or by their depositional environment (large lakes, shallow marine, and lagoon/small lake settings).

    Existing shale oil extraction plants in Fushun and Moaming, China, were closed in the beginning of 1990s. However, the new shale oil plants in Fushun consist of 220 retorts and the annual capacity has increased up to 350,000 tonnes of shale oil. [124] Several other projects have been developed in various locations. [96]
