375. Rock microfluidics under pressure: enabling geochemical observations at subsurface conditions

Wen Song (University of Texas at Austin)

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Real-rock microfluidics have enabled elucidation of in situ fluid-rock interactions at the fundamental scales of length and time (~ μm, ms). These platforms are categorized broadly into three classes: those constructed from rock material (e.g., calcite, shale) that are pressure-constrained by the mechanics of the crystal substrate, those deposited with mineral particulates (e.g., kaolinite,...

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Understanding the transport and deposition of colloidal particles in confined environments is crucial for optimizing natural and engineered systems, such as groundwater remediation and filtration technologies. This study adopts a pore-scale approach, combining microfluidic devices that mimic rock structures with pore-scale flow simulations to investigate clogging mechanisms, uncovering a...

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Groundwater pollutants that become trapped in low-permeable clay lenses are difficult to remediate using conventional pump-and-treat methods. Water flows preferentially through more permeable sandy layers leaving behind residual contamination in clay lenses that then slowly leaches out over time creating a long-term contamination problem. An alternative approach to pumping contaminants above...

54. Coupling microfluidics and Raman spectroscopy to measure concentration gradients in geological porous media

Mr Mohamadou Sarr (ISTO, UMR 7327, Univ. Orleans, BRGM, CNRS, F-45071, Orleans, France)

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Most of the world’s drinking water supply comes from groundwater aquifers. These sources, however, are susceptible to contamination (hydrocarbon, chlorinated solvents, nitrates...). Environmental engineering applications foreseen the usage of charged colloidal particles for groundwater remediation or for sealing damaged geological confinement barriers. However, the injection of colloidal...

327. Probabilistic learning of gas wall interaction from molecular Dynamics simulations and applications to gas transport problems in nano micropores

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Modeling and characterizing gas-wall interactions at the atomic scale are crucial for understanding transport behavior in micro- and nanopores and for accurately simulating gas flows in porous materials. It is well known that gas displacement in extremely tight channels is complex and significantly influenced by adsorption/desorption physics and surface diffusion mechanisms at the boundary...

278. Multiscale Analysis of Coupled Free-Flow and Porous Media Systems: Structured and Random Configurations

Mario Del Mastro

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

This study initially undertakes a detailed experimental two-dimensional analysis of vector fields in both structured and random porous media configurations. Structured media are examined at porosities of 55%, 75%, and 85%, while random media are analysed at 75% porosity. As shown in Figure 1, both the axial and transverse velocity fields are significantly influenced by the geometry of the...

351. Inertia effects on mixing and reactive transport in porous and fractured media

Peter Kang (University of Minnesota)

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Mixing and reaction in porous and fractured media govern a wide range of natural and engineering processes, including carbon mineralization, cave formation, geothermal energy production, contaminant transport, and microfluidics. Subsurface systems often feature fractures and conduits that serve as highways for fluid flow. Typical flow velocities in these systems are high enough to induce...

447. Microfluidic investigation of water-scCO2 phase distributions in vesicular basalt pore system proxies

Ms Kelsey Yao (Columbia University)

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

In this study, we conducted a series of microfluidic experiments using Stereolithography (SLA) 3D-printed chips designed to replicate the pore geometry of vesicular basalts and investigate a scaled version of in-situ supercritical CO₂ (sc-CO₂)/water/basalt multiphase flow dynamics under room conditions and a large parameter space. Multiphase flow phase distributions will impact scCO2...

433. PORE-SCALE VISUALIZATION AND ANALYSIS OF MULTIPHASE FLOW IN FRACTURED POROUS MEDIA

Jorge Avendaño (PUC-Rio)

22/05/2025, 12:35

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Naturally fractured reservoirs contribute approximately 25–30% of global oil production. The presence of fractures, vugs, and interconnected channels introduces complexities in fluid flow within rocks, either by creating preferential pathways or acting as barriers (1). This study seeks to advance the understanding of fluid behavior in fractured rocks and their associated characteristics. To...

191. Investigation of dissolvable gases transport in vadose zone by using micromodel experiments

Yung-Wei Lee (National Taiwan University Department of Bioenvironmental Systems Engineering)

(MS11) Microfluidics and nanofluidics in porous systems

Oral Presentation

Dissolved gases in soil pores play a crucial role in soil pollutant transport, subsurface carbon sequestration, and soil greenhouse gas emissions. The transport of dissolved gases interacts with trapped soil air. Trapped air in soil impedes the transport of dissolved gases in porous media. Meanwhile, the exchange of dissolved gases between liquid and gas phases alters bubble volume and surface...
