description: The subject of the graduate qualification work is Â«Optimization of gas methods for enhanced oil recovery for low-permeability reservoirsÂ». This work is devoted to the study of gas methods for enhanced oil recovery and the selection of the optimal operating mode for wells operating in the Huff-and-Puff. This method of field development provides a significant increase in oil production. And in the end, the most effective operating modes for wells were selected for gas injection. The mode consisted in a combination of constant gas injection, huff-and-puff and depletion work. The research set the following goals: 1. Assessment of the potential of gas methods at the Priobskoye field; 2. Studying different gas use options: permanent injection and Huff-and-Puff; 3. Identification of factors that maximally affect the injection efficiency; 4. Calculation of oil production profiles and optimization of the gas injection regime; 5. Analysis and comparison of results for two gas injection options and selection of the optimal one for the field; Hydrodynamic calculations were carried out on the low-permeability sector of the West Siberian field, which clearly illustrate the greater effect of huff-and-puff injection than from constant gas injection or waterflooding. Also, as a result, the economic payback indicators of the proposed type of development were analyzed and the optimal well operation mode was selected to achieve a higher oil recovery factor with a smaller amount of injected gas.
