Impact of CO2-rich seawater injection on the flow properties of basalts
Lyesse Laloui, Eleni Stavropoulou, Cesare Griner
Permanent CO storage in basalts through mineralisation offers a promising solution for reducing carbon emissions and mitigating climate change. This study focuses on the impact of potential mineralisation on the flow properties of the basaltic material. Fl ...
2024Multiscale Porosity Microfluidics to Study Bacterial Transport in Heterogeneous Chemical Landscapes
Francesco Carrara, Jiande Zhou
Microfluidic models are proving to be powerful systems to study fundamental processes in porous media, due to their ability to replicate topologically complex environments while allowing detailed, quantitative observations at the pore scale. Yet, while por ...
Hoboken2024Water weakening and the compressive brittle strength of carbonates: Influence of fracture toughness and static friction
Marie Estelle Solange Violay, Barnaby Padraig Fryer, Corentin Jean-Marie Rémi Noël
Water is ubiquitous within the pore space of rocks and has been shown to affect their physical and mechanical behaviour. Indeed, water can act on the rock strength via mechanical (i.e., reducing the effective stresses) or chemical effects (e.g., mineral di ...
2024Unsupervised Electrofacies Clustering Based on Parameterization of Petrophysical Properties: A Dynamic Programming Approach
François Fleuret, Karthigan Sinnathamby
Electrofacies using well logs play a vital role in reservoir characterization. Often, they are sorted into clusters according to the self-similarity of input logs and do not capture the known underlying physical process. In this paper, we propose an unsupe ...
SOC PETROPHYSICISTS & WELL LOG ANALYSTS-SPWLA2023Fluid flow through microcracked and fractured granitic reservoirs
Marie Estelle Solange Violay, Lucille Jocelyne Nadine Carbillet, Michael Heap
The permeability of crustal rocks and rock-masses dictates the efficiency of hydrothermal circulation and therefore the productivity of geothermal resources. In this study, we find by monitoring P-wave velocity that thermal microcracking in Lanhélin granit ...
2023Influence of temperature on phase assemblages of belite-ye'elimite cement
Karen Scrivener, Barbara Lothenbach, Diana Londoño Zuluaga, Natechanok Chitvoranund
This paper studies the effect of temperature on the phase assemblages of belite-ye'elimite cement. A comparison is made between thermodynamic modelling and experimental data at 28 and 180 days of hydration at 5, 20, 40, and 60 degrees C. The fast reaction ...
Oxford2023The Permeability of Porous Volcanic Rock Through the Brittle-Ductile Transition
Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer, Corentin Jean-Marie Rémi Noël, Michael Heap
The permeability of volcanic rock controls the distribution of pore fluids and pore fluid pressure within a volcanic edifice, and is therefore considered to influence eruptive style and volcano deformation. We measured the porosity and permeability of a po ...
AMER GEOPHYSICAL UNION2022On the role of pore constrictions in gas diffusion electrodes
Vasiliki Tileli, Robin Pierre Alain Girod, Michele Bozzetti, Yen-Chun Chen
Water management by gas diffusion electrodes is a fundamental aspect of the performance of electrochemical cells. Herein, we introduce the characteristic constrictions size as a descriptor for microporous layers (MPL). This parameter is calculated by volum ...
ROYAL SOC CHEMISTRY2022Freezing-induced stiffness and strength anisotropy in freezing clayey soil: Theory, numerical modeling, and experimental validation
This paper presents a combined experimental-modeling effort to interpret the coupled thermo-hydro-mechanical behaviors of the freezing soil, where an unconfined, fully saturated clay is frozen due to a temperature gradient. By leveraging the rich experimen ...
WILEY2022The effect of pore microstructure on strength and chloride ingress in blended cement based on low kaolin clay
Karen Scrivener, Diana Londoño Zuluaga
The objective of this study is to analyse the mechanical and durability properties of a high-performance mortars based on low grade kaolin clay and the effect of electrical conductivity and pore microstructure on the chloride penetration resistance. A tota ...
