Characterization of N2 foam flow with in-situ capillarypressure measurements in a high-permeability homogeneous sandpack: effect of surfactant concentration and flowrate

Abstract Determining the capillary pressure during foam flow in porous media is important because bubbles are thought to coalesce by lamella rupture as the "limiting capillary pressure" is approached. In this study, the role of surfactant concentration on capillary pressure and apparent vi...
