Abstract
The flow properties of complex fluids through porous media give rise to multiphase flow displacement mechanisms that operate at different scales, from pore-level to Darcy scale. Experiments have shown that injection of oil-in-water emulsions can be used as an effective enhanced-oil recovery (EOR) method, leading to substantial increase in the volume of oil recovered. Pore-scale flow visualization as well as core flooding results have demonstrated that the enhanced recovery factor is regulated by the capillary number of the flow. The mechanisms by which additional oil is displaced during emulsion injection are still not clear. In this presentation, we discuss the different analyses to evaluate the effect of emulsion flooding both at pore and macro scales, combining numerical and experimental methods. The results presented here show that injection of emulsion offers multi scale mechanisms resulting from capillary-driven mobility control.
