Application of the Maxwell–Stefan theory in modeling gas diffusion experiments into isolated oil droplets by water

We have used the Maxwell–Stefan diffusion theory to model mass transfer between tertiary-injected gas and residual oil blocked by water, in order predict time required for rupture of water barrier due swelling. also designed conducted a set visualization micromodel experiments on various pure multicomponent oil–gas systems measure tertiary injection processes. The experimental results show that initial pressure dimensions system, composition, solubility control swelling process. experimentally measured times are then employed evaluate reliability compare its accuracy with similar one using classical Fick's law. Our modeling both models able estimate an acceptable precision. As mixtures, however, only is capable molecular process correctly yields values close reality, while use law would lead erroneous results. Deficiency latter becomes more acute when direction reality contrary what indicates, which leads failure calculating any value at all these cases.
