Coupled effects of gas-water occurrence and velocity-induced permeability damage in CO2-ECBM

Key Points

• Permeability damage is significantly influenced by gas-water occurrence and velocity effects, leading to enhanced challenges in CO2-ECBM.
• Key evidence shows a notable permeability reduction, emphasizing the interaction between water and gas dynamics.
• Assessment based on simulations of gas-water interactions in CO2-ECBM further illustrates the critical role of velocity changes on permeability.
• Understanding these coupled effects may enable better strategies for maximizing CO2 sequestration, indicating a need for advanced approaches.
