As the share of development of oil fields with reserves confined to low-permeable reservoirs increases, the problem of improving the efficiency of key indicators of project implementation becomes relevant. The work considers the factors that influence the investment attractiveness of low-permeable reservoir development projects, based on the accumulated experience in the development of low-permeable layers, the directions of optimization of technical and economic solutions are noted. The effectiveness of the proposed measures is confirmed based on the investment analysis of options for developing low-permeable reservoirs of an oil field.
