Enhanced Oil Recovery (EOR) is an advanced technique in the withdrawal of petroleum. Basically EOR is injection or addition of substances as a method to increase oil production. Based on the process, EOR is divided into four categories, namely thermal, microbiological, miscible process, and chemical. One of methods for EOR is injecting chemicals such as surfactants. Surfactants are one of the compounds that have polar and nonpolar groups that can form an emulsion so can be used in the oil withdrawal. In this study, non-ionic surfactant was synthesized, which is fatty esters of poly(ethyleneglycol) (abbreviated as FEP) using conventional method and MAOS (microwave assisted organic synthesis) method. The conventional method was carried out by refluxing a mixture of poly(ethyleneglycol), used palm oil, and NaOH at various reaction times. MAOS method was carried out by irradiating a mixture of poly(ethyleneglycol), used palm oil, and NaOH using microwave at various raction times and the power of irradiations. The non-ionic surfactant has been successfully synthesized that was indicated by a physical changes demonstrated by successfully dissolution of polar and non-polar compounds. It was also indicated by the appearance of peaks in the IR spectrum at 1737 cm-1 representing the ester group as well as a reduction in the intensity of the peak at 1591 cm-1 which represents -COO- groups. The results of Liquid Chromatography Mass Spectroscopy showed peaks at [M+H+] of 611.8714; 521.7992 and 615.9217 with high intensities that represent the molecular masses of surfactant products. The solution of formulated synthesized surfactant (FEP) in formation solution (brine solution) of tested field showed a transparent solution in the aqueous stability test. In the phase behavior test, the FEP surfactant formed 3-phases and the emulsion in the bottom phase. In the Interfacial Tension (IFT) test, the FEP surfactant showed the IFT value of 3x10-3 dyne/cm. Based on these tests it can be concluded that the synthesized surfactant (FEP) has good potential to be applied in EOR process.
