In order to produce crude oil three recovery techniques are used: primary, second and tertiary also known as Enhanced Oil Recovery (EOR). Oil production in the Carpatian region is difficult due to the long-term production and significant depletion of reservoir energy. One of the methods that are considered to increase oil recovery factor is CO2-EOR. This method is based on carbon dioxide injection into oil reservoir in order to maintain reservoir pressure and modify physicochemical oil properties. Combination of t...
