摘要

This paper reports the investigation of oil–water IFTbehavior when the chromatographic separation of thesurfactant mixture occurs during surfactant/alkalinecorefloods. In this work, surfactant and alkalineconcentrations in the effluent of corefloods andoil–water interfacial tension were determined underdifferent injection strategies. It was found that, in anextended waterflood following an alkaline–surfactantslug injection, surfactant desorbed into the water phase.This desorption of surfactant lasted for a long period ofthe waterflood. Although the concentration of thedesorbed surfactant in the extended waterflood was verylow, an ultra-low oil–water IFT was obtained by using asuitable alkaline concentration. Coreflood results showed that an additional 13% of the initial oil in placewas recovered after the alkaline/surfactant injection bythe synergism of the desorbed surfactant and alkaline.This result indicates that the efficiency and economics ofa chemical flood could be improved by utilizing thedesorbed surfactant during extended waterfloodprocesses.
