Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, Volume 64, Issue 4, Page 405-421, July/August 2026.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, Volume 49, Issue 3, Page 869-906, July 2026.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Complex Electrical Conductivity of a Single‐Fractured Rock: Fracture‐and‐Matrix Coupling Mechanism and Aperture Size Predictions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Fractured rocks play a crucial role in myriad natural and engineered systems, including Earth's critical zone, oil/gas/geothermal reservoirs, and geological CO2/H2/waste storage systems. While complex electrical conductivity is extensively used to estimate the pore and grain sizes of conventional porous rocks and soils, it is rarely used to ...
