Distribution of organic matter in Bazhenov high-carbon formation

One of the most famous and promising shale formations in Russia is the Bazhenov formation. The ambiguity of ideas about its geological features, caused by the complex, heterogeneous structure of the strata, attracts the attention of many researchers. In this work, the Bazhenov formation is singled out in conjunction with its stratigraphic counterparts in the Bazhenov high-carbon formation (BVCHF). In this were considered the main characteristics of its allotment and distribution over the area, as well as the geological structure. Being an unconventional reservoir of hydrocarbons, BVCHF has properties of a petroleum-bearing rock, one of the main characteristics of which is organic matter, its type and maturity. The paper presents the results of the study of organic matter by various methods at the micro level, as well as their integration with larger-scale studies. The need for detailed consideration of the organic matter of the BVCHF is justified by the fact that it has a mixed composition and, as a consequence, a different degree of transformation and spatial distribution.
