摘要
Embodiments of the disclosure provide compositions and methods suitable for injection of a nanosurfactant-based foam composition into a hydrocarbon-bearing formation for enhanced recovery operations. The nanosurfactant-based foam composition includes a gaseous component and nanoassemblies. The nanoassemblies contain a petroleum sulfonate surfactant, mineral oil, and a zwitterionic co-surfactant.
