Rock property determination using digital rock physics
International Meeting for Applied Geoscience & Energy, 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 ...

Industrial Applications of Digital Rock Technology [PDF]
Journal of Petroleum Science and Engineering, 2017 This article provides an overview of the current state of digital rock technology, with emphasis on industrial applications. We show how imaging and image analysis can be applied for rock typing and modeling of end-point saturations. Different methods to obtain a digital model of the pore space from pore scale images are presented, and the strengths ...

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.

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 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.

FRACTAL ANALYSIS OF DIGIT ROCK CORES
Fractals, 2020The rock cores of low permeability reservoirs have special pore structures, which are the essential factors to determine the seepage capacity and oil displacement efficiency and directly affect oil and gas reserves and oil well productivity. This paper studies 16 digital rock core samples.
