Effects of type of salt on nanoparticles-stabilized carbon dioxide foam in enhanced oil recovery

Foam is employed to improve the efficiency by which the displacing fluid sweeps the reservoir and contacts and recovers oil. However, it is known that foam are both thermodynamically and kinetically unstable systems that readily destruct as a result of film drainage, drying, film breakup and gas dif...

Three types of salt (Sodium Chloride, Calcium Chloride and Magnesium Chloride) were used to create six different compositions of brine with total salinity of 3 wt%.

From this study, it was found that different type of salt would affect the stability of nanoparticle-stabilized foam. The 3 wt% CaCl2 at 0.5 wt% SiO2 gave most stable foam and highest oil recovery because of the greater stability of micelles to cause enhanced foam stability.
