Paper Number: SPE-202341-MS
... In summary, achieving miscibility is difficult in depleted oil reservoirs having low pressure. Modified CO 2 can enhance miscibility and reduce interfacial tension at low reservoir pressure which will in turn makes CCUS projects feasible. Experimental studies have been reported reduction in IFT...
