I shall describe how to combine a dynamic pore network simulator for the displacement of oil from a porous medium by an aqueous phase, with a calculation of the advection and diffusion of chemical in the aqueous phase, so as to model certain enhanced oil recovery processes. Results from the coupled simulation show how the occupancy of the pore space differs between different recovery processes, which has implications for the interpretation of measurements made in oil reservoirs during recovery, and reveal that in certain circumstances interaction between the transport of chemical and the displacement of oil stabilizes the overall displacement pattern.
