The conformance of the kinetic spectrum of kerogen to the thermal history of the oil-source reservoir is verified on the basis of numerical modeling of the kinetics of the process of thermal decomposition of kerogen according to the previously determined thermal history of the oil-source reservoir. Then, numerical modeling of the process of laboratory pyrolysis of kerogen, which has passed the stage of modeling the thermal history, is carried out, the calculated values of the degree of realization of the kerogen generation potential and similar values calculated from the data of laboratory pyrolysis of the core for specific wells are compared. Numerical modeling of changes in pore pressure in the oil-source reservoir is carried out and a map of potentially achievable pore pressure in oil-source deposits is built based on the kinetics of kerogen transformation and material balance. Based on the map of Poisson’s ratio values for the oil-source reservoir and the map of the current depths of the formation top of the oil-source reservoir, a map of the pressure of cracking in the oil-producing reservoir is constructed. Then, it is compared point-by-point with a map of potentially achievable pore pressure and promising zones are identified in which the pore pressure reaches values equal to the crack formation pressure, while the crack formation pressure is determined based on the stress-strain state of the oil-source reservoir for a rupture model on the surface of a spherical pore.
