Gas flow characteristics in shale fractures after supercritical CO2 soaking

Using supercritical CO2 as fracturing medium to develop shale gas not only improve the stimulation effect of reservoir, but also reduce CO2 emissions. To optimise the flow of shale gas into a wellbore, it is important to understand the flow characteristics of gas in the shale fracture system after reservoir reconstruction. To date, no research has been conducted on the effect of supercritical CO2 on the flow characteristics of gas in shale...
