The Effect of Seawater on the Interfacial Tension: Smart Water Flooding abstract
The first water flooding by smart water was accomplished in an experimental work in The University of Wyoming during 90s. One of way to achieve smart water is using seawater that by changing salt contents that exist in the seawater, smart water leads to an increase in the capillary number. The main subject of this paper is the effect of smart water on the interfacial tension (IFT) to increase oil recovery.In this study the IFT of the sea water and oil was measured at different concentrations using Pendant drop method. So the effect of SO42- and Ca2+ ions and aging time on the IFT was investigated. The results show that there is an optimum salinity point for sea water where in the lowest IFT and highest oil recovery was obtained. Ions available in seawater have different effect on the IFT. Also aging time affects properties between seawater and oil and cause reduction in IFT.
