Contour plot of relative increase in energy recovery for the cases with CO2 injection compared to regular production. The systems are produced at 0.2 kg/s for 10 years. CO2 injection rate is 10−4 kg/s in the 100 m out-of-plane thickness of the 2D model (10−6 kg/s m). Both dip and thickness influence the recovery. The change in recovery is small but positive; CO2 injection does not impair thermal recovery for these cases
