A Comparison of Screening Methods for Assessing Legacy Wells Within CO2 Storage Licences: Application to Offshore Norway

Greenhouse Gases: Science and Technology, Volume 16, Issue 5, Page 746-757, October 2026.
ABSTRACT Legacy wells represent a critical consideration for offshore CO2 storage projects, as they may provide potential pathways for fluid or gas migration if poorly constructed, undocumented or inadequately abandoned. Systematically assessing large numbers of legacy wells remains challenging due to heterogeneous data availability and the diversity ...

Detecting Anomalies in Karst Aquifer Recharge: A Temporal Convolutional AutoEncoder Framework With High‐Frequency Temperature‐Conductivity Signals

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract The internal recharge dynamics of karst aquifers are difficult to resolve with traditional outlet‐based indicators, owing to their heterogeneous structure and nonlinear response. To address this, we propose a non‐invasive anomaly detection framework based on a Temporal Convolutional AutoEncoder (TCAE), which integrates high‐frequency ...

Dynamics and Mechanisms of Sudden Free Drainage in Saturated Media

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Sudden free drainage in saturated media under gravity is widespread and potentially destructive, yet its controlling mechanisms remain poorly understood. To address this knowledge gap, this study conducted 77 one‐dimensional sudden free drainage experiments covering particle sizes of 2.0–20.0 mm, porosities of 0.40–1, water temperatures of 22 ...

Tracing Orogenic Evolution From Multi‐Detrital Mineral Records: U‐Pb Geochronology and Trace‐Element Constraints From Glacial Diamictites

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

A Dynamic Reserve Evaluation Method for an Ultra-Deep Fractured Tight Sandstone Gas Reservoir

Dynamic reserves evaluation is crucial for the development and assessment of gas reservoirs. However, ultra-deep fractured tight sandstone gas reservoirs pose unique challenges due to their abnormally high pressure, tight matrix, and complex fracture ...

Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...
