Synthetic Rock Salt

Soheil Ghanbarzadeh, Marc A. Hesse, Masa Prodanovic & James E. Gardner
Deep geological storage sites for nuclear waste are commonly located in rock salt to ensure hydrological isolation from groundwater. The low permeability of static rock salt is due to a percolation threshold. However, deformation may be able to overcome this threshold and allow fluid flow. We confirm the percolation threshold in static experiments on synthetic salt samples with x-ray microtomography. We then analyze wells penetrating salt deposits in the Gulf of Mexico. The observed hydrocarbon...

Pore‐scale Multiphase Flow Experiments in Bead Packs of Variable Wettability

Zuleima Karpyn
The aim of this experimental study is to investigate the impact of wetting characteristics on multiphase flow, sweep efficiency, and residual fluid distribution in unconsolidated porous media. A sequence of oil and water injections was performed on bead packs with uniform porosity and permeability, but different wettability characteristics. Uniform and mixed‐wet bead packs with varying degree of wettability were fabricated to analyze how the residual saturation profiles and the distribution of fluid phases at the...

Bentheimer Sandstone

Bagus Putra Muljadi
The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of Bentheimer sandstone and Estaillades carbonate. The critical Reynolds number indicating the cessation of the creeping Darcy flow regime in Estaillades carbonate is two orders of magnitude smaller than in Bentheimer sandstone, and is three orders of magnitude smaller than in the beadpack.

Uniform quartz - Silver nanoparticle injection experiment

Ian Molnar
The dataset contains a series of SXCMT images of a sandy quartz media column during silver nanoparticle injection and elution from this media. The column was imaged 8 times during the silver nanoparticle transport experiment, and 4 images were captured at each time-step (at 4 different energies). Each set of 4 images were compiled to create 1 dataset of pore-scale silver nanoparticle concentration distribution for each time-step.

Gold grains scanned at various resolutions
