E Enhanced Oil Recovery (EOR) method aims to increase oil production. One of the EOR methods is CO2 injection. The CO2 injection mechanism is by expanding the volume of oil, reducing viscosity, and reducing mobility ratio. The research objective was to determine the comparison of the Recovery Factor in the water injection method (waterflood), Miscible continuous CO2 injection, and Miscible WAG CO2 injection with a three-dimensional simulation methodology using CMG Compositional software in the CW field. From the CW field, a sectoral model was chosen to be studied, namely the area of the CW-A well and the CW-B well because the two areas have different reservoir conditions. The optimal pattern of injection wells for the CW-A well area and the CW-B well area is the Inverted Five Spot. CO2 injection is said to be Miscible because the injection pressure and reservoir pressure are above MMP (2800 psi) and there is a mixture of CO2 and oil to form a homogeneous phase. The optimal CW-A (Low Permeability) Well Area using the Continues 4 PV injection scenario (injection rate 31.8 mscf / d) produces an RF of 61.18%. The optimal CW-B (High Permeability) Well Area uses a CO2-WAG 2 PV injection scenario in a cycle time of 90 days (3 months), 1: 3 WAG Ratio (injection water rate 20,036.84 bwpd and gas injection rate 33.75 mscf / d) produces RF amounted to 61.76%.
