Currently, the design and scientific support of hydrocarbons reserves development is impossible without the application of up-to-date techniques, equipment, methods, and approaches to the storage and analysis of field information (digital wells, stationary monitoring, cross-well monitoring and accounting for the mutual influence of wells according to the material balance or deconvolution methods). To ensure the effectiveness of implemented field development system as a whole, it is necessary to regularly conduct survey by well testing and well logging. This survey allows to determine the current parameters of the wells, and to make optimization decisions during further wells operation. At the present state of the art effective development of hydrocarbons reserves can be ensured both by expanding the range of technical means and by combining research methods, minimizing unproductive wells shutdowns.
Since ruling document RD 153-39.0-109-01 "Complexation and stage-by-stage execution of geophysical, hydrodynamic and geochemical researches" has been established the range of wells testing methods has been significantly expanded due to the wide use of multilateral and multilateral wells, drilling of horizontal wells with multi-stage hydraulic fracturing in low-permeability formations, development of inland sea water and continental shelf reserves. All this influenced the choice of research tools, their integration, and clarification of the scope and frequency of monitoring methods, depending on the stage of field development. Methods and technologies for long-term stationary monitoring technological and geophysical parameters of the well operation mode (temperature, pressure, flow rate, product composition, etc.) have been created and continue to be developed using point, point-distributed or distributed stationary information systems installed in production wells for a long time. Updating RD 153-39.0-109-01 is an important step to improve the quality of survey and improve the efficiency of well operation.
