Abstract

Surveys of the Bazhenov formation have been concentrated, primarily, in the central part of West Siberia. The paper discusses the lithology of the Bazhenov Shale in the northern part of West Siberia, in the East-Urengoi license block. For the first time in the history of investigations, the geological section of the Bazhenov formation was divided into five lithological units based on the results of lithological and mineralogical studies and well logging surveys. Concise characteristic of all units is presented. Correlation of lithological units allowed tracing of thickness changes within the territory of the license block.

Key words:

Bazhenov formation, Bazhenov formation anomalous section, Urengoi megaswell, West Siberia, Upper Jurassic
