The study aimed to substantiate a new approach to improving the quality of integrated assessment of the impact of oil and gas technogenesis on the hydrogeosphere of oilfields in Western Siberia. The object of the study is the Apt-Alb-Cenomanian reservoir complex of some oilfields in Western Siberia. The main method is the matrix method of pairwise comparisons (the method of hierarchy analysis), which allows to establish a rating system for the analyzed objects. In this case, it allowed a comparative assessment of the degree of influence of oil and gas technogenesis on the state of the geological environment of the investigated water-bearing complex. Results obtained: comparative assessment of the degree of negative impact of oil and gas technogenesis on the underground hydrosphere of Krasnoleninskoye, Zapadno-Ust-Balykskoye, Megionskoye, Tevlinsko-Russkinskoye, Aganskoye and Kogalymskoye oil fields.
