The kinetic study kerogen transformation to gas and liquid hydrocarbons is required for understanding and modeling of geological (petroleum system modeling) and technological (thermal EOR in application to source/oil shale rocks) processes. Kinetics of the Bazhenov formation kerogen thermal decomposition has been studied for the samples of different maturity. Two approaches were applied, including bulk kinetics, representing the total yield of hydrocarbons, and compositional kinetics, describing various products yields. Results show, the organic matter maturation influences the composition and the amount of kerogen decomposition products as well as kinetics of the process, closely related to the molecular structure of the remained kerogen. We experimentally proved that at each conversion stage the predominant products of the Bazhenov kerogen decomposition are liquid hydrocarbons.
