Reservoir is depleted and it is not feasible to produce remain crude oil with these methods
anymore after the primary and secondary recovery mechanism. However, the large amount of
crude oil called as residual oil volume is still trapped in the reservoir. Enhanced oil recovery
(EOR) is technical injection processes which are focused on extracting this residual oil volume
that cannot be extracted otherwise. The factors that affect oil-water-rock system to trap crude oil
can be summarized as interfacial tension, wettability, mobility ratio, capillary pressure and
reservoir rock properties.
