Modeling Conformance as Dispersion

Abstract: Summary For decades the effect of physical dispersion (in-situ mixing) in porous media has been of interest in reservoir engineering and groundwater hydrology. Dispersion can affect the development of multi-contact miscibility and bank breakdown in enriched gas drives and miscible solvent floods of any mobility ratio. The magnitude or extent of dispersion is quantified by the rock property physical dispersivity (a) which is the order of 0.01 ft for consolidated rocks and sev… Show more

“…Adepoju et al, 2013;Peaceman, 1977). Extensive studies of dispersion at the field scale have been published (Arya et al, 1988;Coats et al, 2009;Lake, 1989) but generalizing the results of these studies is not straightforward. Physical dispersion at smaller length scales is also important because, as discussed below, the description of transport at the core scale can play an important role in the prediction of mixing at the field scale, particularly for carbonate formations.…”
