From phase and wettability studies on bulk phases, we predicted the fluid-fluid-fluid dispersion morphologies that could be expected for ex-situ dispersions (formed before injection) and for the dispersions after they were injected into a porous medium. From videomicroscopic studies of the flow of the dispersions through an etched microvisual cell, we determined the actual morphologies of the dispersions during flow. Three different wettability conditions and three different morphologies of flowing dispersions were observed.
