Interfacial tension reduction and viscosity control by chemically grafted polymeric surfactant for enhanced oil recovery.

ABSTRACT: The production rate of many oil fields has been decreased during recent years. Various old chemical methods have been used to exploit oil reservoirs, such as the use of polymers, surfactant-polymer (SP), and alkaline/surfactant/polymer (ASP). Among all the enhanced oil recovery methods, polymeric surfactants had excellent function for enhance oil recovery (EOR) purposes. This study presents significant research about the influence of sodium dodecyl sulphate (SDS) on the adsorption properties of non-ionic polyvinyl alcohol (PVA) polymer. In other words, the surfactant was placed on the polymer through a direct acid-base reaction in the form of a chemical grafting via the reflex and hydrothermal process for the first time. With this evidence, the surface of PVA polymer was modified and activ
