Multiphysics Monitoring of Capillary, Electrical, and Elastic Responses During Drainage and Imbibition at Reservoir Conditions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Capillary pressure‐saturation relationships are crucial for geo‐energy recovery, and increasingly, for environmental applications. However, for reservoir‐relevant pressure and temperature conditions, only limited data sets are available from special core analysis in laboratory (SCAL) studies.

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.

Petrophysical Properties of an Iraqi Carbonate Reservoir Using Well Log Evaluation

, 2020
This research was aimed to determine the petrophysical properties (porosity, permeability and fluid saturation) of a reservoir. Petrophysical properties of the Shuiaba Formation at Y field are determined from the interpretation of open hole log data of ...

Petrophysical Characterisation in Geothermal Reservoirs: What For?

, 2016
The rocks found in geothermal systems are widely heterogeneous and complex, yet they need to be represented numerically so that the features of the system can be modelled and the system’s behaviour simulated to achieve optimal field management ...

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 ...
