Experimental Investigation of CO 2 /CH 4 Competitive Adsorption Behaviors in Shale under Different Feed Gas Injection Methods
Understanding the CO2 and CH4 competitive adsorption behavior is crucial for the engineering optimization of the CO2-enhanced shale gas recovery (CO2-ESGR) process. Most studies evaluate CO2 and CH4 competitive adsorption behaviors by simultaneously injecting their mixed gases, which does not reflect real conditions,...
