Abstract

The features of the thermal regime of the sedimentary basin of the South Caspian and their reflection in the history of changes in katagenesis of pool rock organic matter are investigated. Numerical reconstructions of the evolution of the thermal regime and the history of pool sinking obtained with application of the pools simulator system GALO are used. Modeling assumes a high and noticeably unsteady modern mantle thermal conditions in the region and expressed activity of processes of dispersion heat transfer, increasing the effective thermal conductivity of the upper sedimentary rocks by several times. Assessment of the degree of katagenesis of organic matter in sedimentary section rocks of the western part of the South Caspian Basin has shown that the rocks of the lower Paleocene, Lower Eocene and Lower Maikop can only be regarded as a gas-generating, while the Middle Maikop rocks can be considered as promising for the generation both liquid and gas hydrocarbons.
