The paper deals with the presented results of one-dimensional modeling of the oil generation history by organic matter contained in various lithotypes of the Bazhenov Formation in the section of one of the Malobalykskoye field wells (KhMAO, West Siberia). The contribution of the each lithotype organic matter to the total volume of oil generation has been assayed. Two history models of the liquid hydrocarbon generation have been calculated. The first model used kinetic parameters of kerogen taken from literature data and being used in the standard library of program product in which the modeling was performed, and the second one used parameters obtained experimentally at IРGG SB RAS for weakly transformed organic matter of the Bazhenov Formation. It was found that the largest amount of liquid hydrocarbons was generated by the organic matter of kerogen-siliceous mixtites and kerogenic silicites.

Keywords: Bazhenov Formation, West Siberia, organic matter, kerogen, kinetic parameters, model.
