1. A computer-implemented method for upscaling with a processing system, borehole-scale digital rock modeling data representing reservoir rock, the method comprising: using the processing system to upscale the borehole-scale digital rock modeling data to interwell-scale digital rock modeling data based at least in part on combining the borehole-scale digital rock modeling data with interwell-scale source data to generate interwell-scale digital rock modeling data that at least partially captures heterogeneity at an interwell scale; using the processing system to upscale the generated interwell-scale digital rock modeling to generate full-field-scale digital rock modeling data wherein the borehole-scale digital rock modeling data has been at least partially upscaled from pore-scale digital rock modeling data; and wherein the upscaling to generate full-field-scale digital rock modeling data is based at least in part on computed values at an interwell-scale from the interwell-scale digital rock modeling data.
