Abstract
Western Siberia has oil and gas potential that is very important for the development of the oil and gas industry in Russia. The north of Western Siberia has special significance for the industry, that's where the maximum aggregate deposit of hydrocarbon reserves is located in fields, such as Urengoy, Yamburgskoye and Medvezhye. Over the last decade, a tendency to reduce the efficiency of geological exploration has appeared, therefore, it is necessary to conduct a comprehensive analysis of the actual material and to select priority areas. The Lower Cretaceous complex of the Cretaceous oil and gas megalithic complex located in the north of Western Siberia is the most lucrative. The Neocomian clinoform Achimov deposits of this complex are the main object of study. Achimov deposits are trapped almost throughout the Nadym-Pur interfluve area and are having a complex structure. The formation of Achimov rocks mostly took place in the deep-water part of the paleosea that affected their heterogeneity. An analysis of the geological and field parameters of the Achimov deposits determined the maximum aggregate of hydrocarbon deposits in the eastern and northern parts of the study area, as well as zones of active rifting. Geological exploration should be carried out in such zones initially.
