An effective medium theory for predicting the mobility of fine-texture dispersions (i.e., foams and emulsions) flowing in porous media is presented. The dispersions are viewed as random arrays of mobile spheres of uniform radius, smaller than the pore radii, imbedded in a fluid of different mobility, and their flow is approximated as a diffusion-limited process. Using a multiple scattering approach, analytic expressions for the mobility of the dispersion in terms of the ratio of the mobilities of the individual phases and the volumetric fraction of the dispersed phase are generated.
