There is a growing discussion of the need for systematic study of underexplored areas within the West Siberian Petroleum Province with the purpose of increasing the resource base and, as a consequence, the discovery of new hydrocarbon deposits. Considering the huge amount of geological and geophysical data acquired over the past quarter century, its synthesis, analysis, and interpretation at the modern information and technological levels can be useful for beginning of a new stage in the West Siberian Petroleum Province development. Above all, this includes the marginal zones of the basin, overlooked or missing intervals and objects having complicated structure (pre-Jurassic, Jurassic, Neocomian, Senonian series). Their investigation becomes a strategically important factor in increasing the mineral resource base of the country. The main focus of this work is a petroleum potential of western margin of the province, which is characterised by the presence of oil and gas bearing and promising in terms of oil and gas content intervals of Neocomian series.
