Abstract: In this paper, for the objects of the Volga-Ural oil and gas province, confined to terrigenous and carbonate reservoirs, a study was conducted aimed at reducing risks and uncertainties when using geological and statistical models. Discriminant analysis revealed a number of inconsistencies in the grouping of objects according to the criterion of tectonic confinement, within which the migration of objects and their significant dispersion relative to the centroids of the groups were revealed. In order to level out the factors of nonlinearity and heterogeneity of processes occurring in disordered oil and gas systems, the boundaries of their stability are formed using four models using algorithms for solving the dual problem by the simplex method. Based on the data obtained, some features of the influence of parameters characterizing the geological and physical properties of productive formations and the fluids saturating them on the integrity and correctness of ideas about the degree of belonging of objects to certain grouping zones are determined. The results obtained make it possible, within the framework of proactive resource management, to create optimal or refine existing algorithms for finding the most suitable analog objects for use at newly discovered sites of the best engineering solutions and practices in the field of field development. Keywords: geological and statistical modeling; oil deposits; tectonic confinement of objects; geological complexes; development of oil fields; asset management of subsoil users.
