The article presents the results of revealing the relationship of siliceous, clay, carbonate and organic substances and pyrite from the types of electrical and radioactive logging. The influence of the content of the listed rock-forming components of rocks on the geophysical characteristics is described. The volume lithological model of the Archinskaya-47 well, constructed on the basis of established correlations, is presented.

For the South-Eastern regions of the West Siberian oil and gas province, a model of the structure of the Bazhenov reservoir and criteria for selecting areas that are promising for detecting oil accumulations in the productive level of the South-West Bazhenov Formation are proposed. According to the our criteria, the following characteristics of the object of research are given: the thickness of rocks of the Bazhenov Formation, the thickness of rocks with a Corg content > 7%, catagenesis degree of organic matter, the thickness of the underlying and overlying fluid barriers, current reservoir temperatures of rocks and reservoir pressures in the Bazhenov Formation. Based on a comprehensive analysis of the materials that characterize the above criteria, promising zones of two categories are identified. The Central-Nyurol zone is assigned to the 1st category (the most promising), and the North-Nyurol, East-Nyurol, South-Nyurol, West-Parabel, and Ust-Tym zones are assigned to the 2nd category.

Zoya Ilyinichna Glezer is the largest Russian micropaleontologist, a specialist in siliceous microfossils — Cenozoic diatoms and silicoflagellates. Since the 1960s, she systematically studied Paleogene siliceous microfossils from various regions of the country and therefore was an indispensable participant in the development of unified stratigraphic schemes for Paleogene siliceous plankton of various regions of the USSR. She made a great contribution to the creation of the newest Paleogene schemes in the south of European Russia and Western Siberia, to the correlations of the Paleogene deposits of the Kara Sea.
