Dispersion in Fractured Porous Media

Because of the influence of dispersion on miscible displacement processes, diffusion and dispersion phenomena in porous racks are of current interest in the oil industry. Dispersion is a consequence of flow. It results from the different paths and speeds and the consequent range of transit times available to tracer particles convected across a permeable medium.The purpose of this article is to investigate diffusion and dispersion phenomena in a fractured porous medium. A mathematical model has been developed for a plug which can be used as a fractured porous media in laboratory. Some miscible tests should perform on such plug and results can be compared to the solution of this model
