The role and importance of reservoir identification in the context of strategic planning for the rational use of oil companies' assets

The work is devoted to the quantitative and qualitative assessment of the significance of the processes of identification of deposits in the context of the need for operational development of residual oil reserves.To solve the problems of effective strategic planning for the rational use of oil companies' assets based on the use of the analogy method, a methodology has been proposed for creating algorithms and techniques for differentiating, grouping and identifying objects in conditions of uncertainty at various stages of field development. Using the example of objects in the Volga-Ural region, the dependence of the percentage of correctly grouped objects on the stage of exploitation of deposits was established using discriminant analysis. An example of identification using the tectonicstratigraphic association of objects is presented. 41 groups were identified in the conditions of the eastern part of the Volga-Ural oil and gas province. As a result of deep differentiation, the objects are divided into 133 groups, each of which is characterized by the peculiarities of the geological structure and the influence of the geological and physical characteristics of productive strata and the physico-chemical parameters of the fluids saturating them. Based on the results obtained, it is proposed to take a differentiated approach to the development of each selected group, which will allow taking into account the peculiarities of the influence of parameters. The presented methodology can be implemented not only within large oil and gas provinces, but also within smaller oil and gas regions and facilities developed by specific subsurface users.
