Surface charge modified nanosurfactants for reduced retention by reservoir rock |
| abstract |
Disclosed here 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, and a cationic co-surfactant. |
