Fluorosurfactant Wetting Agent for Oilfield
Fluorosurfactant wetting agent is a perfluoroalkyl or fluorotelomer-based surfactant used in oilfield applications to alter reservoir rock wettability from oil-wet to water-wet, improving water flood displacement efficiency. At concentrations as low as 50–500 ppm, it dramatically reduces surface and interfacial tension, enabling superior water spreading and penetration into tight pore structures. It is used in stimulation pre-flush, EOR wettability modification, and drilling fluid additive applications.
