In the paper, it is shown that the results of the interpretation of measurements of permanent reference gages on the electric submersible pump (ESP) together with the data on the change in the historical production rate of the wells allow carrying out the justification and support of the oil production enhancement operations and also the analysis of the efficiency of the oil production enhancement operations performed by estimating the current skin-factor of the wells and reservoir pressure. In particular, wells have been identified in which worsening of the skin-factor in time is observed. For them, the optimal time for performing repeated well interventions was chosen to improve the skin-factor and increase production from the wells.
Separate results of the work are represented by an express method for selecting the optimal time for transferring production wells to injectors for pressure maintains to optimize the production of a section of the oilfield based on the telemetry gages on the ESP. At the same time, the forecasts were made on the basis of express 2D models in the software "Topaze", which significantly increases the speed of work execution compared to full 3D modeling, and the accuracy of forecasts remains quite high.
The paper shows that the results of the historical flow rate of wells and the telemetry of pumps are a good informational basis for the application of a new method for analyzing cross-wellbore interference – multi-well deconvolution (MWD).
Thus, without a loss of production, a analysis of the results of a production decline was carried out on the basis of the algorithms for interpretation of the well test and recommendations of production enhancement operations were justified to increase production.
