Alkaline-Surfactant-Polymer (ASP) flooding is considered as a promising method for enhanced oil recovery since 1980's. ASP formulations have been developed using defined screening processes established through experimentation in labs around the world. Due to recent advances in chemical enhanced oil recovery, surfactant can be used to extend the life of mature reservoirs with increasingly A diverse conditions. The objective of this research was to identify high performance surfactant formulations and design efficient core floods by comparing ASP siug sizes for Berea sandstone cores with Indonesia X-field oil and brine samples. Microemulsion phase behavior experiments were conducted to identify best ASP formulation in low salinity condition which is from X-field brine samples. Core floods with well optimized formulation validated its high oil recovery efficiency (~95%) in lab-scale experiments. FinaIJy, This experiments were conducted by which condition is better for high oil recovery according to changing surfactant quantity inciuding ASP slug sizes under the same surfactant quantity condition. Surfactant quantity is defined as multiply Surfactant injected slug sizes (pore volume %) by Surfactant Concentration (wt %). All of Surfactants were from Aekyung chemical technology company.
