Study on effectiveness of supercritical CO₂ on pore enlargement and permeability enhancement in deep ultra-low-permeability volcanic reservoirs

Methodological Theory | 更新时间：2026-01-09

- Study on effectiveness of supercritical CO₂ on pore enlargement and permeability enhancement in deep ultra-low-permeability volcanic reservoirs
- “In the field of deep volcanic reservoir development in the Huoshiling Formation of the Songliao Basin, experts have explored a water rock interaction transformation method based on supercritical CO2, providing new theoretical basis and technical path for economic and efficient development as well as CO2 co storage and enhanced permeability transformation.”
