Improvements are presented on an operator-splitting method on multiple grids for the simulation of transport, and possibly reaction, in highly heterogeneous porous media. The method captures the effect of fine scale heterogeneity on the fluid flow with low numerical dispersion, and has great potential for distributed memory parallel processing of large-scale simulations in the other of a million grid cells. The geological description of the reservoir can be incorporated to a length scale of about one to two feet. Results are discussed for an areal displacement problem with real field data over a domain that extends over several square miles. Performances on an iPSC/860-hypercube for simple problems show the high parallel content of the algorithm.
