Digital Rocks Portal

Masa Prodanovic, Maria Esteva, Matthew Hanlon, Gaurav Nanda & Prateek Agarwal
The Digital Rock Portal has the purpose of enhancing research resources for modeling/prediction of porous material properties in the fields of Petroleum, Civil and Environmental Engineering as well as Geology. This platform allows managing and preserving available images of porous materials and experiments performed on them, and any accompanying measurements (porosity, capillary pressure, permeability, electrical, NMR and elastic properties, etc.) required for both validation on modeling approaches and the upscaling and building of larger (hydro)geological...

Wilcox Tight Gas Sandstone

Ayaz Mehmani, Masa Prodanovic & Kitty L. Milliken
A process-based multiscale network modeling approach is introduced to predict the drainage capillary pressure and relative permeability-wetting phase saturation curves at early cementation, final cementation and feldspar dissolution of the Wilcox tight gas sandstone. Predictions based on a two-scale analysis of an X-ray tomographic image are conducted as well but computational limitations make conclusions uncertain in this paper. We emphasize process-based modeling informed from thin sections as a cheap method of making a priori predictions...

This dataset was used in the study of Van Offenwert et al. (2019). It contains time-resolved laboratory-based micro-CT images of saturated solute injection experiments in sintered glass and Bentheimer sandstone. Based on the grey values in the resolved pore space, pore-scale concentration fields can be quantified. To estimate its uncertainty, calibration scans where the pores were saturated with a known tracer (CsCl) concentration were performed at 12 s per scan with a voxel size of...

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...

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.

Mimicking Geological Fabrics for Multiphase Flow Experiments

Prasanna Ganesan Krishnamurthy, David DiCarlo & Timothy Meckel
2D bead-packs (0.6 m x 0.6 m x 0.02 m) were generated with realistic geological features (cross-stratification and ripple lamination). To demonstrate an application of the technique, gravity unstable multiphase flow experiments were conducted in the generated bead-packs. This project contains time-lapse videos of these flow experiments.

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...
