An algorithm is represented, which allows analyzing the feasibility of the technology of water-gas stimulation of formation to enhance oil recovery. The authors have logically identified three blocks of the data involved. The first block is the source data. The specifics are determined by a particular field and, accordingly, the water and gas consumption and the electricity tariff for the enterprise. Economic parameters are described as the equipment, project implementation, and depreciation costs. The accounted discount rate and property tax should be determined. The macro parameters that may affect the algorithm results have also been considered. I.e., the costs of the US Dollar and the Brent oil. Among the mining and geological parameters, the oil, water, and gas density have been considered, which determine, respectively, the consumption and the economic component of the project. © Published under licence by IOP Publishing Ltd.
