Rhamnolipid-Based Nanosized Dispersed Formulation for Enhanced Fracturing-Fluid Flowback: Phase Behavior, Interfacial Properties, and Porous-Media Performance
Fracturing-fluid retention caused by capillary trapping and surfactant loss during transport through porous media can impair post-fracturing productivity in tight reservoirs. In this study, a rhamnolipid/isopropanol/limonene/water nanosized dispersed formulation was developed as a biosurfactant-based flowback aid. Pseu...
