Most of Indonesian oil field had been categorized as mature filed in which production had been declined for some time. Therefore EOR (Enhanced Oil Recovery) technology is a must to be implemented to these kinds of field. There are several EOR technologies had been employed successfully in laboratory and also field scales, including gas, thermal, and chemical injection. Most Indonesian oil fields have productive layers depth below 2200ft that will not suitable for gas injection. So that chemical injections become an important alternative that can be implemented to more wide range of depths. These technologies cover alkaline, surfactant, and polymer injection. This paper will highlight the selection and formulation of surfactant formulated from MES (Methyl Ester Sulfonates) produced from Palm Oils. These palm oils are available very abundant in Indonesia due to plenty farm palm oil in Indonesia. Normally Surfactants are formulated from petroleum sulfonates which are generated from petroleum base. By using surfactant that will be manufactured from palm oil, it will be expected that the price will be cheaper compare to the surfactant from petroleum. A series of researches have been done to select the sources of palm oils, producing MES by sulfonation processes, and finally surfactant screening for EOR. Several types of MES produced from varies of palm oil taken from market such as: CPO (crude palm oil), several packed palm oils of different trademarks have been generated. These MES, then, have been given codes to differentiate among these MES such as: 1. CCO-MES (A), 2. CCO ME-MES (B), 3. Oleic Acid-MES (C), 4. Natrium Bisulfit-MESI (D), 5. ME+H2SO4-MES2 (E), 6. CPO-MES (F). These MES production, then, have been formulated to become surfactant formula by adding some chemicals and solvent. After that alkaline (Na2CO3) with optimized concentrations were added to generated the best EOR properties. All those Surfactant-MES have been tested using Lemigas standard laboratory EOR screening; those are compatibility tests, IFT measurments, thermal stability, adsorption, filtration, phase behavior, imbibitions and core flooding. The result of the screening of the MES-chemicals mixtures shows that mixture of CPO-MES (F) with chemical and solvent with the mixture composition denoted as FChS811 has the best performance. 1% of this mixture has the best properties for EOR after adding 0.1% Alkaline (Na2CO3). Laboratory test results indicates that fulfill screening criteria such as good compatibility and no precipitation, low IFT, thermal stability, low adsorption, low filtration ratio, Winsor type-1 phase behavior, high RF on imbibition and core flooding tests. This Surfactants-MES mixture has a potential to be implemented for a field trial with Huff and Puff method.
