Experimental evidences show the potential of emulsion injection in the improvement of oil recovery factor. The responsible mechanism for this better reservoir sweep is the water mobility reduction in regions already swept by water. This reduction can be associated with partial blockage of porous media throats by droplets of emulsion dispersed phase. The efficiency of this partial blockade strongly depends on pore geometry, morphological characteristics and physical properties of the injected emulsion. The efficient use of this recovery method is limited by the lack of fundamental understanding of how emulsions flow through a porous medium. This work aims to study the flow of emulsions through pores throats, which are physically modeled by constricted micro- capillaries in the experiments presented here. The results show how permeability varies with geometrical parameters of micro-capillaries, emulsion properties and morphological characteristics. These data define the necessary properties of emulsions according to the reservoir characteristics to obtain the desired blocking effect and serve as input data to capillaries network model of flow of emulsions in porous media.
