Preparation of Salt‐Resistant Gemini Surfactants via Ethylene Oxide Group Regulation for Enhanced Oil Recovery

ABSTRACT Conventional anionic surfactants generally exhibit poor salt tolerance and reduced interfacial activity under high‐salinity reservoir conditions, limiting their application in enhanced oil recovery (EOR). To address this issue, a series of anionic–nonionic isotridecanol...
