Predictive digital rock physics without segmentation
Computers & Geosciences, 2022Abstract 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.

Digital rock physics combines modern microscopic imaging with advanced numerical simulations to analyse the physical properties of rocks. Elastic-wave propagation modelling based on the microstructure images is used to estimate the effective elastic properties of the rock.

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.

Rock property determination using digital rock physics
SEG Technical Program Expanded Abstracts 2003, 2003The 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 ...

Application of Digital Rock Physics for Geophysical Rock Properties
Proceedings, 2012Traditionally,the values of reservoir rock properties have been acquired from log data or direct measurement in a physical laboratory. Recent advances in imaging and image processing, together with improved availability of high performance computing, gave rise to digital techniques for investigating the properties of rock samples.

A (Digital) Future for Saharan Rock Art?
African Archaeological Review, 2018First visited by westerners in the mid-nineteenth century, Saharan rock art has since received a great deal of attention. The richness and diversity of this region is recognised by the inclusion on the UNESCO World Heritage list of three properties: Tassili-n-Ajjer in Algeria, Tadrart Acacus in Libya, and Ennedi in Chad.

Electrical properties of reservoir rocks by digital rock experiments
Global Meeting Abstracts, 2009We carried out Digital rock experiments using the lattice gas automation (LGA) method to investigate the relationship between resistivity index and water (oil) saturation (I-Sw) of reservoir rocks. The effects of irreducible water are examined with LGA simulation by adjusting the height of the irreducible water film.

A digital rock density map of New Zealand
Computers & Geosciences, 2011Digital geological maps of New Zealand (QMAP) are combined with 9256 samples with rock density measurements from the national rock catalogue PETLAB and supplementary geological sources to generate a first digital density model of New Zealand. This digital density model will be used to compile a new geoid model for New Zealand.
