Pore‐Scale Rock‐Typing and Upscaling of Relative Permeability on a Laminated Sandstone Through Minkowski Measures

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Understanding two‐phase flow in laminated sandstones is important for fluid migration control and operational strategy determination in underground energy and hydrology engineering projects. Digital core analysis provides unparalleled understanding of two‐phase flow in complex porous media, but the integration into field analytical workflow is

Natural hydrogen system evaluation in the São Francisco Basin (Brazil)

Science and Technology for Energy Transition
The São Francisco Basin (SFB), a double foreland bordered by two Neoproterozoic belts, hosts a proven hydrogen (H2) system, demonstrated by high concentrations in boreholes and numerous surface H2 emissions, some long-term monitored. However, no detailed

High Resolution Characterization of Lithological Heterogeneity of the Paaratte Formation, Otway Basin (Australia), a Coastal to Shallow-Marine Deposit

Geosciences, 2019
Coastal to shallow-marine deposits are inherently highly heterogeneous in sediment composition due to variable depositional conditions. Representation of heterogeneity at sub-seismic scales is required for understanding flow and geochemical processes and

Estimation of dynamic geologic CO2 storage resources in the Illinois Basin, including effects of brine extraction, anisotropy, and hydrogeologic heterogeneity

Frontiers in Earth Science
Since the vast majority of carbon dioxide (CO2) storage resources in the United States are in deep saline aquifers, optimizing the use of these saline storage resources could be crucial for efficient development of geologic CO2 storage (GCS) resources ...

Integrated Numerical Modelling System for Extreme Wave Events at the Wave Hub Site [PDF]

, 2013
This paper examines an extreme wave event which occurred during a storm at the Wave Hub site in 2012. The extreme wave of 9.57 m height was identified from a time series of the heave data collected by an Oceanor Seawatch Mini II Buoy deployed at the site.
