An experimental investigation of nanoparticle-stabilized CO 2 foam used in enhanced oil recovery

Stability of nanoparticle (NP) stabilized CO2 foam using silica and nanoclay, and the resulting improvement in oil recovery are investigated using modified bulk foam tests and flow experiments using a microfluidic device. The size and uniformity of the dispersion of NPs are characterized via Dynamic Light Scattering. The NP-assisted foam properties are evaluated by: (1) modified bulk foam tests where bulk foam is generated using CO2 under...
