A significant part of the initial geological reserves of LLC “RN-Uvatneftegas” oilfields are concentrated in deposits with abnormally low reservoir properties (porosity, permeability). The organization strategy of pressure maintenance of such oilfields significantly affect to the economic profitability of the reservoir development. One of the major tasks to achieve this goal is to determine the perfect time for application injection wells in oil production before forming the pressure maintenance system. Often, the solution to this issue turns out to be labor-intensive. In this regard, the analytical tool has been developed that allows rapidly assess the perfect time for transferring wells to water injection for pressure maintenance forming. The developed tool is based on a statistical analysis of the decline rate of horizontal wells fluid rates at the RN-Uvatneftegas oilfields. And also a comparative analysis of the results of the developed tool and other existing methods was carried out. The analysis showed that the developed tool is distinguished by its accuracy, simplicity and efficiency of work.
