Development of injection wells selecting criteria for effective impact on the productive formation in order enhanced oil recovery

The criteria proposed in this article will assist making well-substantiated decisions under conditions of current data limitation on the formation, based on the analysis of the current hydrodynamic state of the study area of ​​the productive formation, in order to increase the efficiency of oil and gas production in the field or in its defined zones. In the context of resource limitations and increasing demand for oil and gas, it is essential to develop methods that enable rapid and accurate reservoir diagnostics while simultaneously minimizing economic costs. The article proposes criteria that allow optimizing the impact on the formation based on an analysis of the current state of the formation. This article proposes the selection of injection wells based on the analysis of the current hydrodynamic distribution of fluids in the formation, taking into account well interference. The application of the program module developed in the MATLAB software, designed for mathematical and engineering calculations, enables consideration of the proposed criteria when selecting injection wells, which allows for more accurate and faster optimization of processes carried out on the field. The practical significance of the results is not only in the case of the considered field, but also in the fact that these criteria can be used for any field. The use of the proposed criteria allows solving many oil field problems. Keywords: productive formation, injection well, current hydrodynamic state, enhanced oil recovery, flow.
