In this work, polymeric materials designed for enhanced oil recovery (EOR) were evaluated their intended application. Properties including viscosity, flow through porous media (resistance factor and residual resistance factor), heavy displacement (incremental recovery) assessed terpolymers of 2-acrylamido-2-methylpropane sulphonic acid (AMPS), acrylamide (AAm), acrylic (AAc). The same propertie...

Abstract Combination flooding, which performs well on both sweep efficiency and displacement efficiency, is being extensively utilized in Daqing Oilfield. Surfactant-polymer (SP) flooding alkaline-surfactant-polymer (ASP) are two of the most used combination techniques. According to findings, alkaline lowers oil-water interfacial tension reduces other component’s adsorption. Nevertheless, also ...
