Chemical injection improves oil recovery, but poses challenges. Ionic liquids are a promising material for chemical enhanced oil recovery due to their unique properties. However, their complex structures present a significant challenge. In this article, we discuss the types and performance influencers of ionic liquids in oil recovery. Most ionic liquids contain imidazolium cations and halogen anions. Two mechanisms, interfacial tension reduction, and wettability alteration, justify their performance. Longer alkyl chains and high temperatures increase efficiency.
Maintaining their performance at high temperatures and salinity is crucial for success. Wettability changes have been observed in both sandstone and carbonate rocks in the presence of various ionic systems, transitioning them into a hydrophilic state. Furthermore, these mechanisms synergize effectively with other chemicals like surfactants and polymers. The promising research results of the past decade indicate the substantial potential of these materials in increasing oil production.
