IFPEN has designed several methods to assess the oil potential of a sedimentary rock, amongst others, the Rock-Eval Pyrolysis technique using a standardized pyrolysis apparatus. This technique is used worldwide amongst petroleum companies to compare their results in the same way.
Rock-Eval is a commonly used process to determine the content of the source rock. [20] Hydrous pyrolysis is performed within water and in high pressures; this method can simulate different depths of burial, demonstrating the possibilities of the fate of the source rock and the associated patroleum.

The type of kerogen present in a particular rock formation depends on the type of organic material that was originally present. Kerogen can be classified by these origins: lacustrine (e.g., algal), marine (e.g., planktonic), and terrestrial (e.g., pollen and spores). The type of kerogen depends also on the degree of heat and pressure it has ...
In petroleum geology, source rock is rock which has generated hydrocarbons or which could generate hydrocarbons. [1] Source rocks are one of the necessary elements of a working petroleum system . They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine , lacustrine and deltaic .
Heating the oil shale to pyrolysis temperature and completing the endothermic kerogen decomposition reactions require a source of energy. Some technologies burn other fossil fuels such as natural gas, oil, or coal to generate this heat and experimental methods have used electricity, radio waves , microwaves , or reactive fluids for this purpose ...
The yellow pattern represents the fraction of the rock (excluding fluids) composed of coarser-grained sandstone. The gray pattern represents the fraction of rock composed of finer-grained, i.e. "shale." The sandstone is the part of the rock that contains the producible hydrocarbons and water.
George C. Scott stands in a field in 1971, the year he would passionately snub both his Oscar nomination (for "Patton") and his subsequent win for the role of the notorious U.S. Army general.
[16] [17] The pyrolysis of the rock is performed in a retort, situated either above ground or within the rock formation itself. As of 2008, most oil shale industries perform the shale oil extraction process after the rock is mined, crushed and transported to a retorting facility, although several experimental technologies perform the process in ...
