- •
Membrane technology is an effective EOR method in fractured carbonate reservoir.
- •
Forming a semi-permeable membrane over matrix rock surface is a key process.
- •
EOR rate depends on solution concentration ratio and permeability of matrix rocks.
- •
Its EOR mechanism is attributed to a spontaneously produced osmotic pressure.
