Fluoropolymers to reduce retention of nanosurfactants to carbonate reservoir rock for applications in oil fields

摘要

Embodiments of the disclosure provide compositions and methods suitable for injection of a nanosurfactant composition into a hydrocarbon-bearing formation for enhanced recovery operations. The nanosurfactant composition includes nanoassemblies that contain a petroleum sulfonate surfactant, mineral oil, a zwitterionic co-surfactant. The nanosurfactant composition also includes a functionalized zwitterionic copolymer present in an aqueous environment.
