Elastic and Petrophysical Properties of Shales

ASEG Extended Abstracts, 2007
Although shales comprise a large proportion of the sedimentary pile in many hydrocarbon-rich regions, their behaviour is not well understood from basin scales right down to the microscopic physics of particle interactions. Shale properties impact significantly on exploration, development and production costs through the effect of seismic anisotropy on ...

Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

Pore‐Scale Transition Behavior of Digital Carbonate Rock Dissolution During CO2 Geo‐Sequestration

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Carbon dioxide‐rich brine formation during geological carbon sequestration induces calcite dissolution, governed by the physicochemical coupling of fluid flow, reactive transport, and pore structure evolution. Unveiling the mechanisms that control this dissolution, particularly under varying flow and structural conditions, is essential for ...

Characterising the heterogeneous nature of tufa mounds by integrating petrographic, petrophysical, acoustic and electromagnetic measurements

The Depositional Record
Determination of the physical properties of subsurface geological bodies is essential for georesource management and geotechnical applications. In the absence of direct measurements, this usually passes via geophysical methods such as seismic and ground ...

Micro-computed tomography pore-scale study of flow in porous media: Effect of voxel resolution [PDF]

, 2015
A fundamental understanding of flow in porous media at the pore-scale is necessary to be able to upscale average displacement processes from core to reservoir scale. The study of fluid flow in porous media at the pore-scale consists of two key procedures:
