Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

ADVANCING QUANTITATIVE INTERPRETATION PETROPHYSICS: INTEGRATING SEISMIC PETROPHYSICS FOR ENHANCED SUBSURFACE CHARACTERIZATION

open access: yesEngineering Science & Technology Journal, 2023
This paper explores the integration of Quantitative Interpretation (QI) petrophysics and seismic petrophysics to enhance subsurface characterization. The primary objective is to assess how combining high-resolution well-log data from QI petrophysics with broad-scale seismic data from seismic petrophysics improves the accuracy and reliability of ...

Pore‐Scale Transition Behavior of Digital Carbonate Rock Dissolution During CO2 Geo‐Sequestration

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Carbon dioxide‐rich brine formation during geological carbon sequestration induces calcite dissolution, governed by the physicochemical coupling of fluid flow, reactive transport, and pore structure evolution. Unveiling the mechanisms that control this dissolution, particularly under varying flow and structural conditions, is essential for ...

A ModEx Framework for Watershed Subsurface Investigation With Limited Geophysical Data Using Machine Learning and Hydrologic Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Subsurface heterogeneity influences watershed hydrology strongly but remains difficult to characterize at catchment scales with sparse and costly field data. Geophysical surveys such as electromagnetic induction (EMI) provide local spatial subsurface images yet scaling them to watershed scales and converting EMI‐derived resistivity into ...

Study on the lower limits of petrophysical parameters of the Upper Paleozoic tight sandstone gas reservoirs in the Ordos Basin, China

open access: yesJournal of Natural Gas Geoscience, 2017
There hasn't been a clear understanding of the lower limits of petrophysical parameters of tight sandstone gas reservoirs so far. However, it is an important question directly related to exploration and development strategies.
