Enhanced oil recovery by nonionic surfactants considering micellization, surface, and foaming properties

Abstract Surfactants for enhanced oil recovery are important to study due to their special characteristics like foam generation, lowering interfacial tension between oleic and aqueous phases, and wettability alteration of reservoir rock surfaces. Foam is a good mobility control agent in enhanced oil...
