A Digital Rock Physics-Based Multiscale Multicomponent Model Construction of Hot-Dry Rocks and Microscopic Analysis of Acoustic Properties under High-Temperature Conditions

SPE Journal, 2022
The development of hot-dry rock (HDR) resources relies on the accurate evaluation of acoustic properties. The acoustic properties are usually measured by rock physical experiments.

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.

Digital Rock Physics for Reservoir Characterization

13th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 26–29 August 2013, 2013
The Agencia Nacional de Hidrocarburos (ANH) is responsible for structuring and promoting opportunities for exploration and exploitation of the Colombian subsoil. The agency also assumes functions that emphasize the management of those resources, and proposes studies and research in the areas of geology and geophysics to generate new knowledge in the ...

Elastic Properties of Carbonate Reservoir Rocks Using Digital Rock Physics

Proceedings, 2013
Digital rock physics (DRP) is a new method which determines rock properties, including elastic moduli and acoustic velocities. The concept is to generate representative 3D digital models of the rock structure at different relevant scales and then calculate numerically the corresponding macroscopic properties.

A (Digital) Future for Saharan Rock Art?

African Archaeological Review, 2018
First 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.

FRACTAL ANALYSIS OF DIGIT ROCK CORES

Fractals, 2020
The 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.

Digital Rock Physics: Using CT Scans to Compute Rock Properties

IEEE Signal Processing Magazine, 2018
Profitable production from oil and gas reservoirs is essential in the petroleum industry, and solutions for many reservoir engineering problems rely on an accurate estimation of rock's physical properties. Traditional property estimation using conventional laboratory measurements has a high turnover time.

Digital X-Ray Rocking Curve Topography

MRS Proceedings, 1986
SUMMARYThere is a considerable body of work available illustrating the significance of X-ray rocking curve measurements in micro-electronic applications. For the first time a high resolution (100-150µm) 2-dimensional technique called DARC (Digital Autcmated Rocking Curve) topography has been implemented.
