The share of easily recoverable reserves is steadily declining, and today more and more attention is being paid to technologies that allow the development of deposits with complex geological and physical characteristics. In such geological conditions, effective development of reserves is impossible without the systematic application of a complex of geological and technological measures, including drilling wells with new types of completion that increase the drainage area and inflow intensity. However, the success of such measures decreases as reservoir properties deteriorate, and therefore the task of increasing their efficiency becomes urgent. One of the ways to solve this problem is to determine the parameters of the well-reservoir system using hydrodynamic studies of wells. At the same time, in view of the decrease in permeability and the complication of the design of horizontal wells with multistage hydraulic fracturing, the assessment of system parameters using classical types of hydrodynamic studies leads to an increase in the duration of the shutdown and, accordingly, to significant losses in oil production. This work is devoted to the issue of increasing the efficiency of geological and technological measures in horizontal wells with multistage hydraulic fracturing in a low-permeability reservoir using a «low-cost» type of hydrodynamic testing of wells by analyzing production and pressure in the corporate software package «RN-VEGA». The proposed approach was tested in a field in Western Siberia in a low-permeability zone and made it possible to identify a number of wells with the greatest potential for increased oil production after geological and technological measures.
