Experimental Investigation of Interfacial Interactions of Condensate/Brine/SC-CO2 Systems at High Pressure and High Temperature Conditions

The subject of enhanced natural gas and condensate recovery by supercritical CO2 (SCCO2) injection tends to be bypassed by<br>researchers despite the existence of several laboratory and field studies of CO2 displacements in conventional oil reservoirs.<br>While the phase behavior of SCCO2/condensate system is a critical factor in determining the effectiveness of the recovery<br>process nevertheless, the interfacial tension (IFT) is an important parameter in verifying the efficiency of the displacement<br>process.
