Wave Propagation in 3‐D Poroelastic Media Accounting for Both Mesoscopic and Global Flow Effects

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Biot's theory of poroelasticity is widely recognized as a fundamental framework for describing wave‐induced fluid flow in mesoscopic heterogeneous porous media. However, dynamic numerical modeling of velocity dispersion and attenuation in heterogeneous porous media remains challenging due to (a) the stiffness of Biot's equations and (b) the ...

Image Segmentation and Analysis of Pore Network Geometry in Two Natural Sandstones

Frontiers in Earth Science, 2018
We report the results of pore-network analysis of high resolution synchrotron microtomographic images of Fontainebleau and Berea Sandstones. We segment the gray-scale images of the rocks into constituent phases, and analyze the geometry of the pore ...

Pore‐Scale Mechanism of Anomalous Saturation Dependence for Induced Polarization: Insights From Desiccation Experiments and Pore‐Network Modeling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The complex conductivity method, also known as spectral induced polarization (SIP), is widely used in hydrogeophysical investigations. Power‐law functions with positive exponents between the in‐phase/quadrature components of complex conductivity and water saturation are key petrophysical relationships to interpret field data.

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Inversion of Induced Polarization Parameters From Time‐Domain Electromagnetic Data Using the Debye Decomposition Model

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Time‐domain electromagnetics (TEM) is a valuable tool for exploring seafloor hydrothermal deposits, which are characterized by variations in resistivity and chargeability. Several surveys using the Waseda integrated seafloor time‐domain electromagnetics (WISTEM) have been conducted.
