Potential evaluation on CO2-EGR in tight and low-permeability reservoirs

Potential evaluation on CO2-EGR in tight and low-permeability reservoirs

CO2-EGR, i.e. enhanced gas recovery by injecting CO2, is to displace natural gas by injecting CO2 in the supercritical phase. It can both enhance the recovery of gas reservoirs and realize CO2 storage. Currently, this technique is still at its exploring stage. The effect of CO2-EGR is not clarified,...
