A Deep Learning Dataset for Pre‐Drill Geohazard Assessment in Taranaki Basin New Zealand

Geoscience Data Journal, Volume 13, Issue 1, January 2026.
An open, comprehensive Taranaki Basin dataset that couples 17 well‐extracted seismic attributes with interpreted rock‐physical properties (pore pressure, caliper, logs) to enable robust, reproducible pre‐drill assessment of four drilling geohazards—normal, collapse, overpressure, and combined conditions—and to provide a ready benchmark for machine ...

Study of wellbore instability in shale formation considering the effect of hydration on strength weakening

Frontiers in Earth Science
Shale formations often contain a high proportion of clay minerals, which, upon contact with drilling fluid, undergo hydration expansion. This leads to wellbore instability, a problem that poses significant challenges globally.

Contemporary stress orientations in the Faroe-Shetland region [PDF]

, 2015
The Faroe-Shetland Region (FSR) of the NE Atlantic continental margin contains a number of complexly structured Mesozoic-Palaeogene-age rift basins, but in comparison to the contiguous British Isles and North Sea Basin, the state of crustal stress in the

Integrating Copper Slag Into Thermally Active Building Foundations: A Pathway to Sustainable Underground Energy Storage Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Underground thermal energy storage (UTES) integrated with building foundations is an emerging pathway to decarbonize space conditioning by shifting low‐carbon heat across seasons. This review evaluates copper slag, a high‐density, thermally stable byproduct of smelting, as a dual‐function medium for thermally active foundations.

Nonlinear Seepage Characteristics and Microscopic Oil Displacement Visualization Experiment of Highly Viscoelastic Polymer

Geofluids, Volume 2026, Issue 1, 2026.
Understanding the nonlinear seepage behavior and microscopic displacement mechanisms of highly viscoelastic polymers is essential for optimizing polymer flooding in heterogeneous reservoirs. This study is aimed at clarifying how polymer viscosity, elasticity, and pore‐scale deformation jointly influence flow resistance and oil displacement performance.

Influence of Geological Factors on Asphaltene Precipitation From Crude Oils in Tuoputai Area, Tarim Basin, Northwestern China

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Asphaltene precipitation frequently occurs in oil wells within the Tuoputai area of the Tarim Basin, significantly hindering production efficiency. In addition to external factors, such as temperature and pressure, the effects of geological factors on asphaltene precipitation warrant further investigation.
