Abstract :
Immiscible CO2 flooding is one of interesting methods in enhanced oil recovery (EOR) which is technically and economically feasible in many oilfields around the world. The potential of immiscible CO2 flooding in selected Malaysian oilfield was investigated through laboratory experiments. The live oil sample is prepared in recombination cell under reservoir conditions. The CO2-oil phase behavior is investigated through PVT cell and the electromagnetic viscometer and densitometer are used. The experimental results are verified by correlation and fluid simulation. The results show clearly the effect of CO2 addition on the fluid properties. As expected by CO2 addition the viscosity of oil reduced the saturation pressure and density of oil increased and oil significantly swelled.
