The flow behavior of foam in porous micromodels has been studied visually using etched silicon wafers. Air was injected into homogeneous and heterogeneous porous media which had previously been filled with an aqueous solution of surfactant. Visual observations were made with a microscope-video camera system to determine the flow characteristics of foam under different conditions of pore dimensions, air injection rates, and surfactant concentrations. The mobility of the injected air was calculated from the air flow rate and pressure drop across the micromodel. This work presents descriptions of the apparatus and micromodels used in this study, the observed flow mechanisms, and the air mobility in air-surfactant systems. 18 references.
