How Does Heterogeneity Control Strain Localization Patterns in High‐Porosity Rocks?

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We aim to explore how heterogeneous porosity and grain size contribute to strain localization patterns in highly porous rocks based on phase‐field simulations. The strain localization patterns, including shear bands, dilatation bands, and compaction bands, are commonly observed in geological field studies and laboratory experiments.

Investigating electrical response to water saturation of Agbada sandstone in an x-field Niger delta, Nigeria [PDF]

open access: yes, 2019
In an attempt to characterize a reservoir in a field, importance is given to living models as it serves critical function in estimating if the reservoir under study is economically viable. Having a good knowledge of electrical response to reservoir rocks

Unraveling the Mystery of Melt Migration in Migmatites: From Channeling Instability to Pattern Formation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

JUSTIFICATION OF REPRESENTATIVE DATA VOLUME OF POROSITY AND PERMEABILITY PROPERTIES FOR OBTAINING STATISTICALLY RELIABLE PETROPHYSICAL CONNECTIONS

open access: yesЗаписки Горного института, 2018
The article discusses the issues of justifying the data volume for a petrophysical description of an object based on the results of traditional laboratory measurements, as well as X-ray tomography data processing.

Rate Dependency of Capillary Heterogeneity Trapping for CO2 Storage

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract In this paper, we experimentally quantify and analytically model rate dependent capillary heterogeneity trapping. Capillary heterogeneity trapping enhances non‐wetting fluid trapping beyond pore‐scale residual trapping through the isolation of non‐wetting phase upstream of heterogeneities in the continuum capillary pressure characteristics ...

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Mineralogical modelling and petrophysical parameters in Permian gas shales from the Roseneath and Murteree formations, Cooper Basin, Australia

open access: yesPetroleum Exploration and Development, 2016
To estimate the resources of Permian Roseneath and Murteree gas shales in the Cooper Basin, Australia, geochemical analysis, log interpretation and core analysis techniques were combined to conduct mineralogical modelling and define petrophysical ...
