Supercritical CO2 in Enhanced Oil Recovery

Posted by Jyrki Korpela on October 12, 2015


Oil reservoirs are high temperature and pressure environments that consist of porous rocks, oil, and various gases. Typically, after the primary and secondary oil recovery processes, at least 50% of the original oil still remains in the reservoir. One method for recovering additional oil, termed tertiary or enhanced oil recovery (EOR), involves injecting supercritical carbon dioxide (CO2), to displace and dissolve some of the remaining oil. Surfactants can be used to increase the sweep efficiency of the CO2.
