Low-Frequency Model Constrained Petrophysical Estimation Based on Canonical Correlation Analysis

IEEE Access
Petrophysical estimation serves as a critical tool for quantitative interpretation in reservoir characterization, bridging the gap between petrophysical and elastic parameters. Traditional approaches, which rely heavily on rock physics models, often face

Rate Dependency of Capillary Heterogeneity Trapping for CO2 Storage

Water 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

Journal 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 ...

ROCKS PETROPHYSICAL PROPERTIES

, 2016
AbstractThe worldwide increasing energy demand triggered studies focused on defining the underground energy potential even in areas previously discharged or neglected. Nowadays, geological gas storage (CO2 and/or CH4) and geothermal energy are considered strategic for low‐carbon energy development.

Evaluation of Petrophysical Properties Using Imaging Techniques

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The petrophysics science is concerned with the study and characterization of oil and gas reservoirs for the hydrocarbon potential availability and productivity through the quantitative of rock properties. Porosity is one of the most important property in petrophysics.

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Unstable Drainage Dynamics During Multiphase Flow Across Capillary Heterogeneities

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We use novel, fast 4D Synchrotron X‐ray imaging with large field‐of‐view to reveal pore‐ and macro‐scale drainage dynamics during gas–brine flow through a layered sandstone rock sample. We show that a single centimeter‐scale layer, similar in pore size distribution to the surrounding rock but with reduced connectivity, temporarily inhibits ...

Petrophysical Properties of Casing Cement While Curing

Procedia Engineering, 2017
Abstract For geothermal as a well as hydrocarbon wells the casing is cemented to ensure a good contact between casing and the rock mass and, more importantly, for preventing the contamination of water resources. Cement shall thus have sufficient strength to prevent collapse of unstable formations and sufficient little permeability to prevent movement
