According to the results, the sequence of CO2 foam stability among the nanoparticles can be arranged (ascending order of foam stability) as follows: CuO, TiO2, Al2O3, SiO2. This observed trend can be attributed to the increased interaction energy of silica nanoparticles, which leads to heightened inter-particle repulsive forces. This, in turn, enhances dispersion stability and extends foam half-life. Nanoparticles have demonstrated remarkable efficiency in foam-based oil recovery. The following table categorizes the main experimental laboratory investigations related to the utilization of nanoparticles as stabilizers for foam.
