Petroleum Formation Maturation Kerogen Britannica Petroleum formation, maturation, kerogen: 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. Kerogen, complex waxy mixture of hydrocarbon compounds that is the primary organic component of oil shale. kerogen consists mainly of paraffin hydrocarbons, though the solid mixture also incorporates nitrogen and sulfur. kerogen is insoluble in water and in organic solvents such as benzene or alcohol. upon heating under pressure, however, the.
Petroleum Formation Maturation Kerogen Britannica 60 Off 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. Given the high yield (70%) of aliphatic mono and dicarboxylic acids obtained, these authors concluded that the structure of the kerogen was comprised mainly of polymethylene moieties including long n alkyl and isoprenoid chains, with aromatic structures being only minor. download: download full size image. fig. 53. Factors other than time and temperature also play contributing roles in the pace of thermal maturation and the conversion of kerogen into petroleum. these factors include catalysis and cracking. the presence of sulphur and other metals can act as potential catalysts accelerating the reaction rates (lewan, 1985). Kerogen is the insoluble component of organic rich shales that controls the type and amount of hydrocarbons generated in conventional and unconventional reservoirs. significant progress has.
Formation Of Oil And Gas Source Rock Maturation Migration Factors other than time and temperature also play contributing roles in the pace of thermal maturation and the conversion of kerogen into petroleum. these factors include catalysis and cracking. the presence of sulphur and other metals can act as potential catalysts accelerating the reaction rates (lewan, 1985). Kerogen is the insoluble component of organic rich shales that controls the type and amount of hydrocarbons generated in conventional and unconventional reservoirs. significant progress has. Despite kerogen’s importance as the organic backbone for hydrocarbon production from source rocks such as gas shale, the interplay between kerogen’s chemistry, morphology and mechanics remains. Kerogen formation is complete by the end of diagenesis. the mode of kerogen formation exerts a strong influence on its structure and bulk composition, and hence on oil and gas generating characteristics, during catagenesis. sulfur rich type ii kerogen, occurring in carbonate evaporite source rocks, can generate oil at low levels of thermal stress.
