R emaining petroleum that has become trapped in rock pores and cannot be extracted using traditional techniques can be extracted using enhanced petroleum recovery (EOR) techniques. Chemical injection with surfactants is one of the most used EOR techniques. The purpose of this study was to ascertain how temperature affected the MES surfactants in palm oil. The goal of surfactant injection is to lower the water-oil interfacial tension. The Palm Oil MES surfactant is used in the laboratory investigation at different concentrations of 0.5%, 0.75%, 1%, 1.25%, 1.5%, 1.75%, and 2% at temperatures between 60°C and 90°C with a salinity of 5000 ppm. The surfactant solution was found to be stable based on the outcomes of the aqueous stability testPhase behavior testing was then done to ascertain how the middle emulsion formed. The optimal mid-emulsion was found at 60°C with a concentration of 0.5% and a total emulsion of 7.50%, while at 90°C, the optimal mid-emulsion was found with a concentration of 1.75% and a total emulsion of 6.25%. The IFT value of surfactant at a concentration of 0.5% and 60°C is 5 x 10-1 dyne/cm. Results of the Recovery Factor (RF) at concentrations of 0.5% and 1.75% showed waterflooding of 60% and RF on surfactant flooding of 32.50%. Testing proceeded to the coreflooding stage. This study suggests that adding MES surfactant derived from palm oil to formation water can speed up the injection process and help generate a stable emulsion that lasts longer than two weeks.z
