Abstract

Results of comprehensive geochemical studies of dispersed organic matter of the Bazhenov Formation are presented. The maximum total contents of organic carbon are found in the areas of the Surgut arch and South Nadym megamonoclise. The contents of organic matter are high (up to 24%) at the top of the formation section and gradually decrease to its bottom. By pyrolysis parameters and the composition of hydrocarbon biomarkers, the organic matter is referred to as type II kerogen (sapropelic organic matter) and is localized in the oil window.
