The paper is devoted to modeling of the processes of oil and gas deposits formation of the Vuktyl thrust development area, to which the largest in the Timan-Pechora oil and gas province is associated with the same oil and gas condensate deposit. Oil and gas of deeply buried formations of the autochthon of the overthrust region remains poorly studied. Therefore, application of modern methods of basin modeling is relevant for oil and gas content estimation. In order to simulate the section, Schlumberger PetroMod software package was used. The package allows to determine the history of generation of hydrocarbons on the geological time scale, migration paths, amount and type of oil and gas accumulations in both surface and reservoir conditions. Using the 1D and 2D modeling of the Vuktylskaya-58 parametric well and the overthrust region models were obtained. The models reflect the modern geological section, its evolution during the geological time. The processes of formation of oil and gas were studied. As a result, it was shown that the parent rocks of the allochthonous section part could not participate in the formation of the main gas-condensate deposit of the Vuktyl deposit because they entered only the main oil formation zone.
