Abstract Methyl ester sulfonate (MES) is an anionic surfactant derived from natural oils. Polymers are large molecules composed of many repeated units that increase viscosity as a mobility control. Therefore, polymer and surfactant can be reacted into one substance as an alternative for enhanced oil recovery (EOR) application. The principle of this research is to graft sulfonate groups from MES into the polymer chain. Based on the experiments, the best result of polymerization was obtained at a mole ratio of 1:0.3 MES to acrylamide. Based on the interfacial tension (IFT) measurement, the IFT value decreased from 8.6 to 2.3 mN/m before and after the addition of polymeric surfactant respectively. The synthesis of polymeric surfactant obtained a yield of 1384.79%. Polymeric surfactant is potential candidates to change the initial oil-wet state of the quartz surface to water-wet based on wettability alteration study. According to thermal analysis and emulsification behavior, this polymeric surfactant was thermally stable under the desired reservoir temperature and was able to emulsify crude oil. The adsorption study showed that the adsorption onto the rock surface increased when the polymeric surfactant concentration was increased in the system. Core flooding experiments showed an increase in oil recovery in different concentrations of polymeric surfactant. Although the IFT value of polymeric surfactant is not very low, it has the potential as an alternative surfactant for EOR applications. Keywords Enhanced oil recovery . Interfacial tension .

Introduction Enhanced oil recovery (EOR) is one of the advanced oil recovery techniques to maximize oil production in a reservoir that has decreased production but still has oil reserves. One of the well-known EOR technologies is using surfactants. The main function of surfactants is to reduce interfacial tension and wettability alteration. The situation in Indonesia is that reserves and oil production have declined by 10% every year, while the level of oil consumption has increased by an average of 6% per year. According to the Ministry of Energy and Mineral Resources, oil production showed an increasing trend from month to month. As of June 30, 2016, the average production of petroleum was 834.4 thousand barrels per day (bpd). On * Agam Duma Kalista Wibowo [email protected] 1
