TY - JOUR N2 - Oil can be produced from reservoirs by use of primary methods that use natural reservoir drive, secondary methods, involving a physical displacement of oil and tertiary (enhanced), in which additional types of energy support oil recovery. About 25-35% of original oil in place for light and medium oil and about 10% heavy oil could be extracted by primary and secondary methods. Injection of CO2 into the oil fields (CO2-EOR) is one of the tertiary oil recovery method. Carbon dioxide is used for increasing oil extraction due to the fact that: to maintain reservoir pressure, reduces the oil viscosity and facilitates its movement in the reservoir, reduces density and increase the volume of oil, interacts with rocks. Depending on the oil composition and the reservoir pressure and temperature injected carbon dioxide can displace oil from the reservoir miscible or immiscible. Additional 10-20% of the oil extraction over primary and secondary methods recovery can be obtained under the miscibility conditions, in immiscibility condition additional oil production is lower. EOR method selection depends on many geological, reservoir and economic parameters. These include: density, viscosity and composition of the oil, minimum miscibility pressure, the recovery factor and vertical and horizontal reservoir variability. Using the above criteria appropriate EOR method for given oil field can be selected. The five parameters: the reservoir depth, the oil density, pressure and temperature of the reservoir is used for the selection of oil fields suitable for miscible oil displacement.
