Overview
The Nano Micellar EOR and Water Block Remediation System is an advanced chemical solution based on self-assembled nanoscale micellar structures. It is designed for enhanced oil recovery in unconventional reservoirs and complex pore systems.
By forming stable nano-micelles in situ, the system enables deep penetration into nano- and micro-scale pore networks, significantly improving multiphase flow behavior and interfacial dynamics. It effectively reduces oil–water interfacial tension (IFT), modifies rock wettability, and lowers capillary trapping forces, leading to enhanced mobilization of residual oil and improved recovery efficiency.
