Novel application of PEG/SDS interaction as a wettability modifier of hydrophobic carbonate surfaces

Abstract Wettability alteration of carbonate reservoirs from oil-wet to water-wet is an important method to increase the efficiency of oil recovery. Interaction between surfactants and polymers can enhance the effectiveness of surfactants in EOR applications. In this study, the interaction of polyet...
