Shale oil in Bazhenov formation on deposits of Western Siberia

[摘要] The Bazhenov shale, the unique object of concentration of nonconventional reserves of hydrocarbons, is the main petromaternal rock of the central part of the West Siberian lowland. It is traced practically in all its territory, both by seismic cuts, and according to correlation schemes of wells' cuts. According to some experts' estimates, about 15% of oil resources in Western Siberia occur in siliceous and clay rocks of the Bazhenov shale, where at the beginning of 2016 more than 90 fields with inflow of oil from clay rocks are registered. Owing to high inhomogeneity of the layer, low filtrational and capacitor properties, high water repellency, geological and other features, the Bazhenov shale on Western Siberia fields either has not been developed, or oil production conducted as trial tests. The main goal of this article is the presentation of researches' results and development of the Bazhenov shale on two perspective fields of Western Siberia.
