Co-surfactants have an important role to increase oil and reduce the tension between the interface of oil and water. The purpose of this research use of co-surfactants and thermal stability at the laboratory scale. The surfactants used in this study are ABS, MES and SCI with a concentration of 0.3%. The ingredients used were Aquades, NaCL and EGBE. The equipment used in the thermal stability test was the Oven. The thermal stability testing was carried out by the surfactant for 30 days then heated at a temperature of 60°C according to reservoir conditions. Success in testing thermal stability considers compatibility with thermal stability. ABS surfactant on day 1 contained an oil layer while for days 3 to 30 the compatibility was clear and the IFT value obtained was 10-2 dyne/cm. SCI surfactant observation day 3 and 7 day compatibility oil layer so it doesnt resistance to heat stability while on days 1 to 30 the compatibility is clear and the IFT value obtained is 10-2 dyne/cm. MES surfactant observations from day 1 to day 30 obtained a compatible solution and the resulting IFT value is 10-2 dyne/cm but 21 day observation the IFT value obtained is 10 −3 dyne/cm. So the surfactant compatible with the use of co-surfactants can affect thermal stability.
