Petroleum potential of Lower Jurassic and Pre-Jurassic reservoirs of Ust-Tym megadepresion

The relevance of the research is caused by the need of reproduction of oilfields area resource base in southeast of Western Siberia. The main aim of the research is to identify and to propose the priority areas for exploration and development of oil and gas complexes of the Lower Jurassic and Pre-Ju...
