Methyl Ester Sulpltonale (MES) is a surfactant (surface active agent) that can reduce interfacial tension between water and oil. The compound can be diluted not only in water but also in oil. MES surfactant as produced by reacting methyl ester and sodiumbusulfite with a ratio of 1:1.5 at 100°C for about 4.5 hours (Pore, 1976). MES surfactant can be applied in chemical stimulation processes to increase and enhance oil recovery (EOR) by reducing the inter facial tension of oil and water formation. ...
