Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

open access: yesThe Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

Quantitative characterization of pore development and its application in shale oil reservoirs of the Qingshankou formation, Songliao basin

open access: yesScientific Reports
The pronounced multi-scale heterogeneity and complex wettability heterogeneity of shale oil reservoirs are key factors governing the distribution and flow behavior of fluids within the pore network. This study focuses on the Qingshankou Formation, Member

SC-CO

open access: yesCase Studies in Thermal Engineering
Supercritical carbon dioxide (SC-CO 2 ) fracturing, compared to water-based fracturing fluids, is a promising technology for developing shale gas because it can effectively solve problems related to shale swelling and increasing the fracturing complexity

Advances in the reservoir characterization from well logs using ML and rock physics analysis: a case study from the West Offshore Nile Delta, Egypt

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
The limited availability of shear-wave velocity (Vs) logs in deep-water reservoirs presents a significant challenge for reliable reservoir characterization and elastic property analysis.

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

open access: yesBasin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Separating Environmental Modulation From Source Intermittency in Methane Leakage From a Legacy Well in British Columbia

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Legacy oil and gas wells are an incompletely quantified source of greenhouse gas emissions and offer leakage pathways for subsurface gas migration if inadequately isolated. We present a high‐resolution, process‐based characterization of leakage dynamics at an integrity‐compromised legacy gas well in northeastern British Columbia using five ...
