Petroleum geodynamics of the West Siberian sedimentary megabasin

DOI 10.31087/0016-7894-2019-3-39-46

Jurassic-Lower Cretaceous formations of Western Siberia are the most promising petroleum exploration targets, and expectations of hydrocarbon production level restoration in the country is associated with them. Depositional settings for Jurassic and Lower Cretaceous formations in the West Siberian Petroleum Basin are determined on the basis of geological and geophysical data integration. Paleogeographic maps for the main West Siberian Jurassic and Lower Cretaceous plays are created, they are: Toarcian (Lower Jurassic), Bajocian, Bathonian, Callovian (Middle Jurassic), Oxfordian, Kimmeridgian (Upper Jurassic), and Berriasian, Valanginian, Hauterivian, and Barremian. Criteria of formation and distribution of reservoir rocks and stratigraphic traps associated with them are established. In the Jurassic series, stratigraphic traps are confined to buried paleochannels and associated coastal facies, and also with delta-front fans and sandy-silty bodies of the coastal-marine zone. Non-structural traps in Lower Jurassic clinoform sequences are associated with alluvial fans of turbidity streams and shallow-marine deltaic and depositional bodies of shelf zone (bars, delta fans, and delta channels). The predicted zones of reservoir rocks formation and zones of stratigraphic traps associated with them are identified and mapped. The predicted maps created allowed estimating hydrocarbon potential of the territory and resource potential of Jurassic and Lower Cretaceous oil and gas bearing series within the unallocated fund of subsurface mineral resources.

Key words: depositional settings; combination traps; West Siberian Petroleum Province; facies; paleogeographic maps.
