Chemically enhanced water-alternating-gas injection for improved CO2 sweep efficiency and geological sequestration in CO2-EOR: Insights from physical experiments and molecular simulation
Addressing gas channeling, limited sweep efficiency, and restricted CO2-oil miscibility in heterogeneous reservoirs during CO2-enhanced oil recovery (CO2-EOR) remains a critical challenge. Herein, a novel pressure-regulated, hydrophilic CO₂-responsive hydrogel-to-foam transition system is used to en...
