Alkaline flooding is capable to mobilize and recover a part of residual oil remaining after waterflood. It is an enhanced oil recovery technique which involved the injection of alkaline chemical such as sodium hydroxide or sodium carbonate during waterflooding operations. The reaction that takes place between alkaline chemical and certain types of oil leads to surfactant generation in situ. It will eventually lead to reduction of interfacial tension (IFT) hence improve the oil recovery. In numerous literatures, alkaline flooding is mostly done on high acid number crude. However, there are also cases of successful alkaline flooding in low acid number crude. In addition, there is no exact theory that relates acid number with oil recovery. In this study, the mechanisms of alkaline water flooding in low acid number crude are investigated. The improvement of oil recovery in alkaline flooding does not only depend on the acid number. Emulsification contributes to improvement of oil recovery. In addition, the formation of Winsor Type III microemulsion shows the desirable condition during EOR. This project is carried out by experimental work and simulation using UTHCHEM software.
