The effect of nanoparticle types on carbon dioxide foam flooding in enhanced oil recovery

Carbon dioxide (CO2) flooding is a well-established and extensively used enhanced oil recovery technique. However, the mobility of the CO2 in the reservoir is higher than the mobility of crude oil which viscous fingering and gravity segregation problems always occur during CO2 injection. To overcome...
