Oil shale geology is a branch of geologic sciences which studies the formation and composition of oil shales–fine-grained sedimentary rocks containing significant amounts of kerogen, and belonging to the group of sapropel fuels. Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Different types of kerogen contain different amounts of hydrogen relative to carbon and oxygen. The hydrogen content of kerogen is the controlling factor for oil vs. gas yields from the primary hydrocarbon-generating reactions. Structured kerogens include woody, herbaceous, vitrinite, and inertinite. Amorphous kerogens are by far the most prevalent and include most of the algal material. The conversion of kerogen to oil and gas is thus a process which requires both higher temperatures than one finds at the surface of the earth and a long period of geological time. Only when temperatures of about 80–90 C are reached, i.e. at 2–3 km depth, does the conversion of organic plant and animal matter to hydrocarbons very slowly begin to take place.

Petroleum - Petroleum - From kerogen to petroleum: the mature stage: Deeper burial by continuing sedimentation, increasing temperatures, and advancing geologic age result in the mature stage of hydrocarbon formation, during which the full range of petroleum compounds is produced from kerogen and other precursors by thermal degradation and cracking (in which heavy hydrocarbon molecules are broken up into lighter molecules).

Kerogen is solid, insoluble organic matter in sedimentary rocks. Consisting of an estimated 10 16 tons of carbon, it is the most abundant source of organic compounds on earth, exceeding the total organic content of living matter by 10,000 fold. It is insoluble in normal organic solvents and it does not have a specific chemical formula.

This type of Kerogen comprises organic matter of microorganisms which is mostly from sea, they settle down at the bottom of the sea when they die and deposit. These type gives mostly oil and less gas. subsurface petroleum phase state (oil sensu liquid and gas sensu vapour). In our model of immature SOM we deem oil (C,,) to be represented by the Rock-Eva1 thermal volatilate (Sl) yield. We define kerogen by difference, as that proportion of SOM which does not yield a thermal volatilate. In Kerogen has been associated historically with source rocks but has gained more notice recently as the source of hydrocarbons in so-called gas shale and oil shale (unconventional) reservoirs. Kerogen is the source of oil or gas in the free porosity and can also hold producible gas within its structure in the form of adsorbed gas.
