    Definition immature hydrocarbon stored in large volumes in shales and other very fine-grained rocks with extremely low permeability, in which the volume necessary for storage is provided by small fractures and extremely small pore spaces Reference "- 'Impacts of shale gas and shale oil extraction on the environment and on human health' (23.4.2020); European Parliament - Directorate General for internal policies - Policy Department A: economic and scientific policy - Museum of the Scottish shale oil industry: Museum > Knowledge > Geology (23.4.2020)"
    Comment "The oil itself is still in a premature status, called kerogen. To transform kerogen into oil it needs to be heated up to 450 °C (pyrolysis). Very often, the kerogen is mixed with layers of already mature oil in structures in between the source rocks with low permeability. This oil is classified as tight oil, though very often the separation is unclear and the transition is fluent by gradual changes of maturity. In its pure state, tight oil is mature oil trapped in layers of impermeable rock of low porosity. Thus, tight oil extraction in general requires hydraulic fracturing techniques. See also: - high-volume hydraulic fracturing (related)- tight oil (related)- unconventional hydrocarbon (broader)"
