Abstract

Sulfonated Alkyl Ester (SAE) surfactant is an amphoteric surfactant that has sulfonated groups and ester groups as its hydrophilic groups. This surfactant is expected to reduce the interfacial tension between waxy oil and brine for its application in surfactant injection to improve waxy oil recovery. In this study, the mixture of SAE and a nonionic surfactant Fatty Ester Oxide (FEO) with certain ratio, hereinafter referred to as SAE-01B, showed a better performance than SAE and FEO surfactants in term of lowering interfacial tension between waxy oil and water, resistance to salinity, and microemulsion formation. This study shows that SAE-01B able to provide good performance for its applications in surfactant injection to improve waxy oil recovery.

Keywords: EOR, Surfactant, Sulfonated Alkyl Ester
