iS‐GNN: Interpolation of Crustal Stress Maps Using a Graph Neural Network Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Estimating the orientation of the maximum horizontal stress (SHmax) from sparse and unevenly distributed geophysical observations remains a persistent challenge in tectonic and geomechanical stress studies. Classical interpolation methods often neglect the multiscale tectonic–geological heterogeneity of the crust, leading to biased estimates ...

Global Azimuthal Anisotropy in the Transition Zone

Science, 2002
Surface wave dispersion measurements for Love wave overtones carry evidence of azimuthal anisotropy in the transition zone of Earth's mantle (400 to 660 kilometers deep). A Backus-Gilbert inversion of anisotropic phase velocity maps, with resolution kernels mainly sensitive to the transition zone, shows a robust long-wavelength azimuthally anisotropic ...

Formation azimuthal anisotropy

The Leading Edge, 1999
Since the first wireline log was acquired in 1927 in France, most of the information recorded in wellbores has been representative of changes in formation properties as a function of depth in or near the borehole. The data are one dimensional, with depth being the only variable.

Wide‐azimuth processing for azimuthal anisotropy analysis

SEG Technical Program Expanded Abstracts 2004, 2004
Azimuth-friendly data processing is mandatory in a reliable fracture characterisation workflow. Here, the effects of standard processing methodologies in the presence of azimuthal anisotropy are investigated on synthetic and real data examples. Common techniques for signal processing, statics calculations, imaging and velocity analysis are adapted for ...
