A perspective review of applications of the computed tomography (CT) scan imaging technique for microscopic reservoir rock characterization

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 4-27, March 2026.
In this review, the application of micro‐CT and medical‐CT scanning in the oil and gas industry has been thoroughly discussed. Recent improvements in DRP and modern imaging techniques in the oil and gas industry have been modeled using both experimental and simulation work.

Drilling Within the Critical Zone

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.

Measurement of Gas Fraction and Gas Permeability of Thawing Permafrost Caused by Climate Change

open access: yesEarth's Future, Volume 14, Issue 3, March 2026.
Abstract Thawing of permafrost due to climate change is known to release gases such as the climate drivers carbon dioxide and methane, as well as the carcinogen radon. Gas permeability is extremely low in fully frozen permafrost and can be considered both to function as a seal preventing subsurface gases being released, and to prevent the creation of ...

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband
