<![CDATA[Natural-based surfactant such as methyl esther sulfonate, which is derived from palm oil, has increasingly become the focus of study for the last decade to improve oil recovery due to the abundant raw materials availability and the need for oil as a source of energy. Surfactant MES development with the targeted fl uid reservoir characteristic has been conducted in the laboratory scale as well as in the fi eld scale. In this study, the addition of polyethylene glycol mono-oleate as co-surfactant to enhanced oil recovery in the “L” oilfi eld in Central Java was investigated in the laboratory scale through compatibility 12 observation, IFT measurement, thermal stability and core fl ooding tests. The results showed that the presence of PMO improved the solubility of surfactant mixture in the water which formed one phase milky solution. Decreasing IFT as the crucial factor for surfactant fl ooding was also achieved until 10-3 dyne/cm and thermally stable for two months. Furthermore, core fl ooding experiments to study the performance of surfactant to recover oil production showed that the mixture of MES and PMO are able to enhance oil recovery until 55.35% Sor and have potential to be used as chemicals for chemical fl ooding in the targeted oilfi eld.
