The Effects of Palm Oil MES Surfactant and Inorganic Salt Concentration on Interfacial Tension Values

Abstract

The application of methyl ester sulfonic (MES) surfactant for enhanced oil recovery (EOR) was based on its ability to reduce interfacial tension in crude oil-water system that reached 10'3 dyne/cm. Performance of methyl ester sulfonic (MES) surfactant from palm oil can be identified with the spinning drop IFT method. The objectives of this research were to detemine MES surfactant perfonnance with the addition of inorganic salt in different conditions. The dispersing media used in this research were demineralized water and information water. The spinning drop 1FT method was conducted usin spinnillg drop tensiometer TX500D tested in 40, 50 and 60''C. Results showed that reduction of 1FT values was affected by MES surfactant and inorganic salt concentration In the demineralized water and formation water as dispersion medium. Methyl Ester Sulfonic surfactant could react better at salinity ranges of 5000-25000 ppm
