CO2/N2-Responsive Nanoparticles for Enhanced Oil Recovery During CO2 Flooding

During CO2 flooding, serious gas channeling occurs in ultra-low permeability reservoirs due to the high mobility of CO2. The chief end of this work was to research the application of responsive nanoparticles for mobility control to enhance oil recovery. Responsive nanoparticles were developed based...
