The effect of foam quality, particle concentration and flow rate on nanoparticle-stabilized CO mobility control foams.

CO foam is regarded as a promising technology and widely used in the oil and gas industry, not only to improve oil production, but also to mitigate carbon emissions through their capture. This paper describes a series of nanoparticle-stabilized CO foam generation and foam flow experiments under reservoir conditions. Stable CO foam was generated when CO and a nanosilica dispersion flowed through the core sample under 1500 psi and 25 °C.
