Abstract

A highly branched green low surface energy surfactant (LSES), stable in harsh conditions, was synthesized for enhanced oil recovery (EOR). Oil recovery factors were determined using a glass micromodel and indicated a 72% increase in oil recovery in both low and high brine solutions, a remarkable res...
