The distribution of cumulative production and current oil reserves of all categories, differentiated by administrative subjects located within the West Siberian oil and gas province, shows significant heterogeneity in the distribution of these indicators across stratigraphic horizons. For each horizon, an integration of the reserves-to-production ratio criterion (A category) and water cut is carried out. It is shown that the main share of both cumulative production and current recoverable reserves that ensure this production falls on the Neocomian complex, which has critically high water cut and low flow rates.
