Abstract:
This purpose of this paper is to investigate and compare different gas injection scenarios in an Iranian oil reservoir using Eclipse 300 software. It models recovery factor, cumulative recovery, and the effective parameters of gas injection during different procedures of CO2 gas injection and Water Alternating gas (WAG) injection. Recovery factor, cumulative recovery, remaining oil saturation, and reservoir pressure are studied and compared during different CO2 gas injection and WAG injection scenarios to specify an optimized pattern of injection process for EOR purpose.Laboratory data of reservoir rock and fluid are matched by usingPVTi software and the results imported into Eclipse formodeling miscible CO2 injection and WAG injection. The results showed that oil recovery and remaini ng oil saturation during WAG injection in reservoir are 31.8 and 56.6% and during miscible CO2 injection are25.8 and 60.4% respectively. In case if WAG injection is highly suggested instead of miscible CO2 injection.
