    Abstract: This studys aims to investigate and compare different gas injection methods in one of Iranian oil reservoirs that are done using Eclipse 300 Software. This study investigates recovery factor, cumulative recovery and the effective parameters of gas injection during different procedures of CO<sub>2</sub> gas injection and Water Alternating Gas (WAG) injection. At last, recovery factor and cumulative recovery are studied and compared during different WAG injection scenarios to specify an optimized pattern of injection. Laboratory data of reservoir rock and fluid are matched in PVTi Software and the results are imported into Eclipse for modeling miscible CO<sub>2</sub> injection and WAG injection. The results showed that oil recovery during WAG injection in reservoir and miscible CO<sub>2</sub> injection is 31.8 and 25.8%, respectively. In case if WAG injection is highly suggested instead of miscible CO<sub>2</sub> injection.
