This study provides a solution to generate CO2 foam above its supercritical conditions by replacing part of CO2 with N2 (mixed CO2/N2 foam). The mixed foam not only generates strong foam above CO2 supercritical conditions but also remarkably increases the oil recovery. This solution overcomes the difficulties associated with the formation of CO2 foam at HPHT conditions enabling the use of the CO2-foam system for effective EOR and other applications of CO2 foam such as conformance control.The glycerol shock treatment has been used to impr
