A comprehensive analysis of seismic data, logs, geochemical and lithological studies in the sediment interval of the Bazhenovskaya and Maryanovskaya suites was performed. On the example of zonal work, regional dependences of the Corg content on the values of apparent resistance are confirmed. The facies boundary of the transition of sediments of the Bazhenovskaya Formation to the Marianovskaya Formation has been substantially refined.

Keywords: southeast of the Tomsk region, Bazhenoskaya and Maryanovskaya formations, dynamic and kinematic analyzes, organic carbon, generation potential.
