The conventional oil recovery methods leave large amounts of oil in the reservoir. Alkaline‐Surfactant‐Polymer flooding is one of the most novel chemical enhanced oil recovery methods in the petroleum industry. Because of the synergy of these three components, ASP is widely practiced in both pilot and field operations with the objective of achieving optimum chemistry at large injection volumes for minimum cost. Alkaline works to help lower the bond attachment between the oil and the field. Alkaline/surfactant/polymer (ASP) flooding is of increasing interest and importance because of high oil prices and the need to increase oil production. The ability to lower the surface tension between aqueous solutions and other phases is one of the most significant aspects of surfactants that raise their applicability in industries. surfactant separately, it showed that injection below optimal sa- linity was successful because a gradient in local soap-to-surfactant ratio developed during the process.

Surfactants can be injected directly (chemical EOR) or they can be generated in-situ by reaction with injected caustic (Alkaline-Surfactant-Polymer EOR). Traditional demulsifiers are not suitable for dehydrating crude oil recovered by ASP flooding because it contains high percentages of the displacement agents (alkali, surfactants, and polymer) [2-4]. Phase behavior was studied with the reservoir oil at different water-oil ratios and varying salt/alkali concentrations. We used an approach that models the behavior of the surfactant-oil-water-microemulsion system based on solubility data. ASP.
