Abstract
One of the major problems agreed upon in CO2 gas injection is early gas breakthrough attributed to unfavorable mobility in the reservoir. The objective of this study is to study the effect of liquid CO2 injection to oil recovery. The core was displaced with crude oil after brine saturation. The next step was water flood by injecting 12 PV of 10,000 ppm concentration brine. Finally, the preconditioned liquid CO2 was injected and the produced oil was recovered. The result of this study gave an interesting oil recovery with a range of 67.7 to 72.6% depending on the temperature of the CO2 injected.
