Investigation of the Pilot Industrial Works Efficiency on the Infill Well Spacing on the Bashkirian Deposits of Sokolkinsky Field with the Use of the Geological‑Technological Model

In this paper, to assess the effectiveness of pilot industrial works on the infill well spacing in the Bashkirian deposits of Sokolkinsky field, factors affecting the final technological indicators are identified. It is possible to refer the following factors to such category: the number of simultaneously commissioned wells in the element; selection of the optimal development element (five-point, nine-point, etc.); organization of the reservoir pressure maintenance system (the ratio of production and injection wells); the time interval for the reservoir pressure maintenance system in the development element. The proof of this fact is the results analysis of the three options considered, which makes it possible to determine how the development system, the ratio of production and injection wells, and the time of wells transfer for injection affect the production of oil.
