Abstract: The carbon dioxide injection into mature oil reservoirs makes it possible to increase the oil recovery and reduce CO2 emissions to the atmosphere. The analysis of the CO2-EOR method applicability on a given reservoir requires forecasting of the production most often conducted with the use of compositional simulators with a high degree of complexity. Due to the increasing popularity of the CO2-EOR method a new methodology for preliminary evaluation of its impact on the oil recovery based on the material balance equation was proposed in this paper. On the basis of the proposed methodology the novel computer application was developed. The obtained results indicate that the developed solution makes it possible to quickly and effectively estimate the potential of the carbon dioxide injection into oil reservoirs to achieve a synergistic environmental effect.
