First, all the oil fields were screened to identify the technically feasible fields for gas EOR. Second, the best injection strategy was selected for each field based...

... be 11.9% which is higher than the 10% oil recovery by 13.2% PV of water and gas injection. This suggests that immiscible lean gas injection is inferior compared to the water injection and EOR benefit by lean gas injection would not be expected. Abstract To sustain the long term production from...
