Permeability evolution in sandstone [electronic resource] : digital rock approach / Ayako Kameda. 2005. 1 v. : digital, PDF file. Adviser: Nur, Amos. Thesis (Ph.D.)--Stanford University, 2005. Permeability is perhaps one of the most important yet elusive reservoir properties, since it poorly correlates with elastic properties, and as a result, cannot be mapped remotely. Physical permeability measurements may be augmented or even partially replaced by numerical experiments, provided that a numerical simulation accurately mimics the physical process. Numerical simulation of laboratory experiments on rocks, or digital rock physics, is an emerging field that may benefit the petroleum industry. For numerical experimentation to find its way into the mainstream, it has to be practical and easily repeatable, i.e., implemented on standard hardware and in real time. This condition reduces the feasible size of a digital sample to just a few grains across. Will the results be meaningful for a larger rock volume? The answer is that small fragments of medium- to high-porosity sandstone, such as cuttings, which are not statistically representative of a larger sample, cannot be used to numerically calculate the exact porosity and permeability of the sample. However, by using a significant number of such small fragments, it may be possible to establish a site-specific permeability-porosity trend, which can be used to estimate the absolute permeability from independent porosity data, obtained in the well or inferred from seismic measurements.
