..., propagation and sweep of NCF-st-CO 2 foam in fractured systems by using a self-designed visual heterogeneous fracture network. We found that NCF-st-CO 2 foam produced noticeably greater pressure drop (Δ P ) than CO 2 foam during either co-injection (COI) or surfactant solution-alternating-gas (SAG...
