The purpose of selecting wells for geological and technical activities (GTA) is relevant for most fields that have been in development for a long time and characterized by a high degree of water content. Engineering approaches and various elements of geological and field analysis are used to address these issues. The analysis of areas and the selection of wells for planning activities are conducted based on full-scale 3D geological and hydrodynamic modeling. This approach is considered to be the most progressive and reliable. There are several complications related to the inability to quickly identify promising areas for side drilling. In order to quickly identify these areas, to choose the optimal method of their development and the azimuth, it becomes necessary to develop additional methods that are accessible and efficient, but do not reduce the reliability of forecasts and calculation of the effect of the proposed GTA. The article discusses an approach that includes preliminary area calculations of the expected production indicators, which enables to accelerate the procedure for selecting areas for the main types of GTA. The work analyzed formulas for calculating forecast oil flow rates for the main types of production wells at the Vikulovskaya formation of the Krasnoleninsky uplift, and initial data for calculations were established. The results of the calculations are maps of forecast oil flow rates that take into account the geological properties of the site, its current energy state, and the water cut of the extracted product.
