Mechanistic study of nanoparticles�surfactant foam flow in etched glass micro-models
This study was conducted in order to identify the pore-level mechanisms controlling the nanoparticles�surfactant foams flow process and residual oil mobilization in etched glass micro-models. The dominant mechanism of foam propagation and residual oil mobilization in water-wet system was identifie...
