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.

Predictive digital rock physics

2021
Geophysical surveys are the most effective way to model the surface and subsurface. Recorded signals can only be converted to properties of interest, such as rock type or saturating fluid, if we understand the relationship between rocks and their physical properties.

Digital rock-dust meter

Review of Scientific Instruments, 1989
This article describes the design of a digital rock-dust meter suitable for measuring the rock-dust content in coal-rock-dust mixtures in a mine environment. The work discusses the probe, digital circuitry, and equations used by the instrument. Data from several mines verifying the 2% accuracy of the device is also presented.

Predictive digital rock physics without segmentation

Computers & Geosciences, 2022
Abstract Measuring physical properties from rock samples is necessary in geosciences to calibrate models from geophysical surveys. Digital rock physics is one way to estimate these properties. X-ray computed tomography (CT) images can be used to create 3D numerical models of rocks.
