Multiscale Digital Rock Analysis for Complex Rocks

Transport in Porous Media, 2021
Many properties of complex porous media such as reservoir rocks are strongly affected by heterogeneity at different scales. Complex depositional and diagenetic processes have a strong control on the pore structures, leading to systems with a wide range of pore sizes covering many orders of magnitude in length scales.

Rock property determination using digital rock physics

SEG Technical Program Expanded Abstracts 2003, 2003
The Digital Rock Physics (DRP) technology is based on a rigorous numerical simulation of physical experiments in a realistic pore space, at the pore-scale level. The output is usually a macroscopic property conventionally measured in the lab. For example, a single-phase viscous fluid flow simulation through a digitized pore space provides absolute ...
