Major engineering breakthrough of Well XA‐1, the deepest ten‐thousand‐meter well in a global sedimentary basin

Deep Underground Science and Engineering, EarlyView.
Well XA‐1, completed at a true vertical depth of 11 156 m in the Shawan Sag of the Junggar Basin, is the deepest predominantly near‐vertical well drilled in a sedimentary basin. The figure shows the basin's tectonic framework and well location (a), a structural cross‐section spanning the Shawan Sag and adjacent uplifts (b), and the stratigraphic column

Using machine learning classifiers together with discrimination diagrams for validation of rock classification labels

Applied Computing and Geosciences
Rock classification based on chemical components is a common task in the geochemical domain. Literature recommends the Total Alkali and Silica (TAS) discrimination diagram for classifying igneous volcanic rocks by the sum of Na2O and K2O in relation to ...

Renewable energy mapping in Northeastern Morocco: A geographic information system‐based comparison of geothermal, solar, and wind potential in the Guercif‐Guilliz and Beni Snassen regions

Deep Underground Science and Engineering, EarlyView.
The graphical abstract summarizes a geographic information system (GIS)‐based synthesis of renewable energy resources in Northeastern Morocco, focusing on the Guercif‐Guilliz and Beni Snassen areas. It visually presents the spatial distribution of solar irradiation and wind energy potential derived from available datasets, alongside their relationship ...
