Abstract

Oil production efficiency has become a priority over oil companies in recent years, because it can significantly increase economic investment. In this regard, great interest has been devoted to the development and application of various Enhanced Oil Recovery (EOR) methods. The previous researchers proposed the EOR method which is considered capable of increasing the productivity of oil recovery in a more economical and environmentally friendly manner is to use the Low Salinity Waterflooding method, which is an IOR/EOR technology that increases the microscopic sweep efficiency of waterflood by reducing and optimizing the salinity of injection water. Therefore, in this study, the authors will again analyze the effect of Low Salinity Water Injection on ASP synergy. In the ASP synergy method using a variety of parameters such as concentrations of salinity, alkali, surfactant, polymer. The fluid components used are Sodium Carbonate as Alkali, Alkylbenzene Sulfonate (ABS) as Surfactant, Hydrolized Polyacrylamide (HPAM) as Polymer. Using a concentration of 20,000 ppm salinity, 500 ppm alkali, 12,500 ppm surfactant, 1,350 ppm polymer, bottom hole pressure and producer 350 psi, water rate 1,000 bbl. Optimum results are obtained where the recovery factor value is 65.31%
