Grain Packing

Mohammad Saadatfar
Partially crystallized packings of frictional, equal-sized spheres. A batch of approximately 200,000 beads is poured into a cylindrical container forming an initial packing in a random configuration with a volume fraction ranging from 57% to 63%. The packing is then shaken intensely for few seconds, to the point of fluidization, where a fast compaction is observed. The resulting global packing density reaches 70.5%.

Induced rough fracture in Berea sandstone core

Zuleima Karpyn, Christopher Landry & Masa Prodanovic
X-ray microtomography was used to map the internal structure of a rough fracture. The artificially created fracture was oriented parallel to the natural bedding of the rock.

Two-Fluid Micromodel Experiments

James McClure
An experimental microfluidic approach based upon image analysis of nitrogen displacing decane in a 500 μm × 500 μm × 1.5 μm micromodel experiment. The pressures on the boundary of the cell were changed and the system was observed as it dynamically relaxed to an equilibrium state. These images capture microscale equilibrium configurations that can be used to determine fluid saturations, interfacial areas, and curvatures.

Amer Alhammadi, Branko Bijeljic & Martin Blunt
Three high resolution X-ray micro-tomography datasets of carbonate reservoir rock samples obtained after 20 pore volumes of waterflooding at subsurface conditions. The three samples (Sample 1, Sample 2 and Sample 3) have been aged to restore the reservoir wetting conditions (mixed-wettability). The mixed wetting conditions have been characterized by in situ effective contact angle measurements using the automated algorithm developed by AlRatrout et al., 2017 applied on the segmented images. More details can be found...

Intergranular Pore Structures in Sandstones

Chul Moon & Matthew Andrew
Dataset: Sandstones (Bentheimer, Doddington, and Rotleigend) X-Ray Microscopy (XRM) is used to examine the intergranular pore structures in a series of sandstones. All three sandstone samples are imaged using a ZEISS Versa X-ray Microscope (XRM) (ZEISS X-Ray Microscopy, Pleasanton, CA). 3D volumes of the varying resolution are reconstructed from a series of 1600 projections, sequentially acquired at evenly spaced angular increments during a 360° rotation. Each projection consists of 1024 x 1024 pixels and is...

Digital Rendering of Sedimentary Relief Peels

Tip Meckel
Sedimentary-relief peels from field environments have been a primary observational technique for decades. Hundreds (likely thousands) of specimens of variable quality exist, representing a wide range of acquisition techniques, and depositional processes and sedimentary environments (e.g., Martinius and van den Berg, 2011). Peels are traditionally used to recognize and explain depositional processes and sedimentary textures qualitatively. This project is an effort to digitally capture sedimentary heterogeneity information represented by these unique specimens that are larger...

Gold grains scanned at various resolutions

Richard Ketcham
This project was to develop and test a method to measure the size and shape of particles that are small relative to the scan resolution, in a way that is accurate, reproducible, objective, and resolution-invariant. The scans are of an artificial core containing 12 gold grains embedded in quartz powder and epoxy (some iron filings are also mixed in), with sizes ranging from 100-300 microns (sphere-equivalent diameter), and a range of shapes. There are 12...

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.

Particulate Straining in Simple Porous Media

Hasan Khan, Masa Prodanovic & David A. DiCarlo
A number of glass bead packs have been sintered to slightly consolidate them and create artificial rock samples with high porosity (~42%) and uniform grain size (~1 mm). One of the samples was imaged with x-ray microtomography, and the others were flooded with different suspensions. Core flooding has been done for different flow rates, concentrations and bimodal particle sizes and each sample and CT images were taken before and after each suspension flood.
