Experimental investigation of anionic and cationic surfactants performance in clay-rich sandstones

Abstract Enhancing oil recovery in clay-rich sandstone formations presents challenges such as low interfacial tension (IFT) and poor fine migration control, which severely impact permeability and recovery efficiency. This study introduces a novel sequential injection strategy using cationic (CTAB) a...
