Petrophysical Signatures and Mineral Endowment: The Piché Group, Augmitto–Bouzan Sector, Québec, Canada

Geophysical Prospecting, Volume 73, Issue 9, November 2025.
ABSTRACT Hydrothermal alteration plays a crucial role in the precipitation of gold and other metals, particularly within orogenic gold deposits hosted in mafic and ultramafic rocks. This alteration significantly modifies the rock matrix, leading to changes in its petrophysical properties.

Petrographic characterization to build an accurate rock model using micro-CT: Case study on low-permeable to tight turbidite sandstone from Eocene Shahejie Formation [PDF]

, 2018
Pore scale flow simulations heavily depend on petrographic characterizing and modeling of reservoir rocks. Mineral phase segmentation and pore network modeling are crucial stages in micro-CT based rock modeling. The success of the pore network model (PNM)

Characterizing Spatial Heterogeneity of Hydraulic Conductivity Using Borehole NMR in a Complex Groundwater Flow System

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Borehole nuclear magnetic resonance (NMR) logging can yield estimates of hydraulic conductivity (K) in unconsolidated sediments. Previous studies focused on establishing petrophysical models relating NMR responses to K and calibrating model constants for optimized K estimation.

Sedimentological and biofabric patterns for hybrid coquina deposits: Insights from wave tank experiments

Sedimentology, Volume 72, Issue 6, Page 1992-2024, October 2025.
ABSTRACT Hybrid bioclastic/siliciclastic coquinas are sedimentary accumulations typical of coastal‐ and shallow‐water settings, where wave breaking, longshore drift and wave shoaling drive sediment transport and control the final accumulations. These processes resulted in thick packages of sediments, as identified in the Lower Cretaceous depositional ...
