The solutions are used to develop a front tracking algorithm, which can solve the slug injection problem where low salinity water is injected as a preflush...

... base and test brines. Because interfacial tension (IFT) reduction reduces the capillary end effect, in the case where the second brine reduces IFT, the field-scale oil recovery may be overestimated. In the case where the fractional flow curve of the second brine is significantly shifted in favor...

... this behavior. In our approach, we propose a method of upgridding which can be applied for either secondary or tertiary recovery processes. Our method is analytical and is based on an idea that fractional flow of a fine scale model has to be preserved on a coarse scale. We use fractional flow on a fine scale...
