Supercritical CO2-water-shale Interactions under Supercritical CO2 Stimulation Conditions
Energy Procedia, 2018 Abstract As one of the main unconventional gas reservoirs, the exploration and exploitation of shale gas reservoirs has been a hot spot of global resources development. The traditional water-based fracturing fluid with the disadvantages of large water consumption and serious formation damage does not apply to shale gas reservoirs stimulation ...
