Popis:	Summary Corefloods were conducted and simulated to evaluate oil recovery from field cores by injection of hydrocarbon solvents. Heterogeneity and fingering were evaluated separately by conducting computed-tomography (CT) -aided single-phase stable and unstable floods. In the absence of bypassing, oil displacement by an equimolar mixture of C2, propane, and butane (C234) is first-contact miscible and C2 (C2) flood is multicontact miscible. In corefloods, heterogeneity and fingering cause oil bypassing. Bypassed oil remains miscible with injectant C234 but becomes immiscible with injectant C2. Two heaviest pseudocomponents drop out in the bypassed region to form a residual oil saturation (ROS) of ≈ 25%.
