The facies structure of the Vasyugan Formation deposits within the junction of the Surgut Dome and the Northern Nizhnevartovsk Megaterrace

详细

This paper considers the lithological peculiarities of the structure and formation conditions of the Upper Jurassic productive reservoirs in the junction zone of the Surgut Dome and the Northern Nizhnevartovsk Megaterrace in the Western Siberia Oil and Gas Basin. Based on the study of core samples and logging data we suggested a fundamentally new formation model for the U₁¹ reservoir deposits in the Vasyugan Formation, which makes it possible to specify the major directions of further exploration.
