Abstract

In the West Siberian sedimentary-rocky basin, it is projected to open mainly small hydrocarbon deposits, the total reserves of which can cover only a small amount of current hydrocarbon production. However, to date, the potential resources of Mesozoic deposits have been transferred to industrial categories by no more than 25-30%. Consequently, there is a certain reserve of undiscovered hydrocarbon deposits. For their successful detection, it is necessary to change the methodological justification and methodological approaches to the forecast, the estimation of resources and reserves, and the geological exploration work that has developed to date. It is necessary to shift attention from large oil and gas-bearing complexes to specific strata and wells. It is also possible to calculate the initial geological reserves of hydrocarbons for individual wells. At the same time, geological exploration and oil and gas production should be accompanied by a detailed study of deep drilling and geophysical research materials using modern processing techniques and geological interpretation of primary geological and geophysical materials. One of the most effective methods is the paleofacial analysis of productive deposits.
