Abstract
In this paper 2D and 3D modeling of thermal evolution of sedimentary cover and OM evolution of the source-rock sequences (SRSs) of the East Siberian Sea were conducted. The distribution of the temperature and reflection of vitrinite in sedimentary cover is presented along the composite seismic profile of the section. Maps of the distribution of the temperature of sedimentary sequences, reflection of vitrinite of the SRSs for various temporal boundaries, and the degree of OM transformation of the SRSs for the presentday stage of evolution were plotted. The evolution of OM maturity and possible processes of hydrocarbon generation of the SRSs were analyzed on the basis of modeling results.
