672. Evolution of subsurface fluid-rock-microbial systems over geologic timescales

Jennifer McIntosh

(MS27) Invited & Plenary Speakers

Oral Presentation

Our understanding of how complex subsurface porous and fractured rock, fluid, and microbe systems are coupled and have dynamically evolved over geologic time is limited. Yet, this knowledge is necessary for effective subsurface resource and waste management over millennial timescales. Fundamental questions include: How do changes at the land surface alter fluid flow, fluid-rock reactions, and...

667. Water transport through hygroscopic porous materials (paper, wood, textiles, fiber panels): a subtle three-phase flow

Philippe Coussot (Univ. Paris-Est)

19/05/2025, 16:35

(MS27) Invited & Plenary Speakers

Oral Presentation

Most bio-based materials, such as paper, natural textiles, sponges, wood or plants, fiber panels for insulation, are porous systems through which water transfers play an essential role in the applications. A specificity of these materials is that they are also hygroscopic: they can absorb huge amounts of water, typically up to about 25% of their dry mass, from ambient vapor, in the form of...

668. Phase-field modeling for multiphase flow and geomechanical processes

Luis Cueto-Felgueroso (Universidad Politecnica de Madrid)

(MS27) Invited & Plenary Speakers

Oral Presentation

Phase-field models have proven to be effective simulation tools for describing interfacial processes at computationally feasible scales. Recent applications of these models include simulating the nucleation and propagation of hydraulic fractures in geological formations, as well as the behavior of fluid-fluid interfaces during flow through permeable media. The phase-field approach seeks to...

670. The Influence of Multiple Scales in Fractured Media on Flow and Transport Properties

Jeffrey Hyman (Los Alamos National Laboratory)

20/05/2025, 08:30

(MS27) Invited & Plenary Speakers

Oral Presentation

In low-permeability fractured media, such as granites and shales, flow and the associated transport of dissolved solutes is controlled primarily by fractures embedded within the rock matrix. The geometry of individual fractures, size and aperture, as well as the network structure determine the structure of the fluid flow field. However, the relevant lengths scales within a fracture network...

674. Anomalous Transport in Porous Environments due to Energy Barriers, Self-Propulsion and Dynamic Confinement

Daniel Schwartz (University of Colorado Boulder)

21/05/2025, 08:30

(MS27) Invited & Plenary Speakers

Oral Presentation

The dynamic behavior of molecules and nanoparticles in confined environments, such as at interfaces and within porous materials, lead to complex and highly-varied phenomena, where heterogeneity may arise from spatial variation of the material/interface itself, from structural configurations, or through inhomogeneous dynamic behavior. To obtain relevant information about these complex dynamics,...

671. Reactive transport processes in porous rock sample: role of local heterogeneities.

Linda Luquot (CNRS-Géosciences Montpellier)

21/05/2025, 08:30

(MS27) Invited & Plenary Speakers

Oral Presentation

The percolation of acidic fluids through natural rocks (e.g. CO2 storage, Karst formation, geothermal formation) induces chemical reactions of dissolution and/or precipitation, which consequently alter the structural and hydrodynamic properties of the rock. These reactions are not uniformly distributed but instead become localized based on various local parameters, such as fluid velocity...

692. Gravity currents in heterogeneous media

Prof. J. Jaime Gómez-Hernández (Universitat Politècnica de València)

22/05/2025, 08:30

(MS01) Porous Media for a Green World: Energy & Climate

Oral Presentation

Heterogeneity could be called the "beast" of subsurface modeling. We know that it exists, but often we disregard it because of the complexity of properly handling it. After a quick recall of the importance of heterogeneity in subsurface modeling, we analyze the progression of gravity currents in heterogeneous media under different kinds of heterogeneity, more precisely, multiGaussian...

510. Soil redox dynamics mediated by interacting biological and physical processes during Managed Aquifer Recharge

Veronica Morales (University of California, Davis)

22/05/2025, 08:30

(MS27) Invited & Plenary Speakers

Oral Presentation

Managed aquifer recharge (MAR) strategies hold potential for improving groundwater quantity for crop irrigation, yet they also pose risks to groundwater quality. The introduction of exogenous water into the subsurface, whether by flooding or well injection, creates geochemical gradients in redox potential, pH, and major ion compositions. In turn, these gradients can induce dissolution...
