Changes in the kinetic characteristics of domanik organic matter during its thermal evolution

The kinetic characteristics of hydrocarbon formation by organic matter of natural series domanik rocks with different levels of maturation and domanik rocks after a series of autoclave experiments at different temperatures are studied. The work uses a method for calculating the realization of hydrocarbon potential for a series of rocks that takes into account the previous thermal history of organic matter. It is shown that the calculation of the realization of hydrocarbon potential based on the kinetic characteristics of immature rock for high stages of domanik organic matter transformation is incorrect starting from a certain level of thermal maturity, which is determined by changes in the chemical structure of kerogen due to oil generation. The data presented in this work indicates this change level a 50 % degree of transformation of the organic matter of the source rock.
