Data sets for Bentheimer and Buff Berea sandstones, used for testing velocity field simulator. Tomographic images and segmented data are available, with a selection of corresponding pressure and velocity fields. See Publications tab for details on segmentation method and velocity simulation algorithm. These samples were imaged and made available by Petrobras, who are gratefully acknowledged.

This project includes high resolution micro-CT images of one xenon hydrate growth experiment in sand. Data are from a paper by Xiongyu Chen, Rahul Verma, D. Nicolas Espinoza and Masa Prodanovic, published in Water Resources Research in 2018, titled "Pore-Scale Determination of Gas Relative Permeability in Hydrate-Bearing Sediments Using X-Ray Computed Micro-Tomography and Lattice Boltzmann Method" Conditions for xenon hydrate growth in sand: T=23C, P_initial =3.72 MPa. Aqueous phase is 10wt% NaBr brine. The image...

A time-resolved synchrotron X-ray micro-tomography dataset of a waterflood in an altered mixed-wet Ketton limestone

Willem-Bart Bartels Maja Ruecker, Willem-Bart Bartels, Steffen Berg, Frieder Enzmann, Arne Jacob, Hassan Mahani, Niels Brussee, Christian Hinz, Apostolos Georgiadis & Christian Wagner
The dataset contains time-resolved synchrotron X-ray micro-tomographic images (grey-scale and segmented) of a waterflood experiment in a mixed-wet Ketton limestone sample. The tomographic images were acquired at a voxel-resolution of 3 micrometer and scanning time of 7 s. The data were collected at the TOMCAT beamline of the Swiss Light Source of the Paul Scherrer Institute (PSI SLS), with the aim to investigate pore scale processes in crude oil - brine - rock systems. Understanding...

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...

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...

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...

Pore-scale imaging of multiphase flow at steady state for a Bentheimer sandstone

Qingyang Lin, Branko Bijeljic, Ronny Pni, Martin Blunt & Samuel Krevor
Images of imbibiiton process for a Bentheimer sandstone at different fraction flows

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.

Gildehauser Sandstone

Steffen Berg, Ryan Armstrong & Andreas Weigmann
Micro-CT scans of a fast synchrotron-based micro-CT flow experiment performed in Gildehauser sandstone rock. The data set consists of - dry scan (at higher quality settings that the flow experiment itself) - dry scan segmented - time sequence of imbibition experiment (40 s time intervals), segmented into rock, oil and water phase

Stalagmite ML-1 NCT and XCT scanning

Barbara Wortham
Stalagmite ML-1 was scanned using neutron and x-ray computed tomography to assess the internal structure and liquid inclusion distribution. The x-ray computed tomography data illustrate the internal calcite density and crystal structure. The neutron computed tomography data show the distribution of light atoms, like hydrogen, in the stalagmite lattice.

Texturally Equilibrated Pore Networks

Soheil Ghanbarzadeh, Masa Prodanovic & Marc A. Hesse
This dataset contains final texturally equilibrated pore structures using level set method. For more info see related publications.

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...

Fines migration in sediments containing methane hydrate during depressurization

Han Gyeol & Tae-Hyuk Kwon
This project presents the X-ray CT image sets obtained during depressurization of methane hydrate bearing sediments. Particularly, the imaging experiment aims on quantifying the extent of fines migration in sediments containing some fines due to depressurization. In this study, three sediments were tested as follows: (a) Ottawa 20-30 sand with 9%w/w silica silt (b) F110 sand with 11.5%w/w silica silt (c) F110 sand with 6%w/w kaolinite and 4%w/w silica silt. These three are referred to...

Micro-CT scCO2-Brine Data

Dustin Crandall Laura Dalton
These files are Berea and Mt. Simon sandstone micro-CT data sets at residual conditions from the paper Methods to Measure Contact Angles in scCO2-Brine-Sandstone Systems. They are 16-bit image stacks cropped from one larger sandstone micro-CT scans and are being provided for additional researchers to use manual and automated contact angle measurement methods to measure contact angles for a comparison to the paper results.

A Super Resolution Dataset of Digital Rocks (DRSRD1): Sandstone and Carbonate

Peyman Mostaghimi Ying Da Wang
Digital Rocks Super Resolution Dataset 1: Sandstone and Carbonate micro-CT Images used for 2D and 3D Super Resolution Machine Learning Training, Validation, and Testing.

The dataset is organised in a similar fashion to the DIV2K dataset : (https://data.vision.ee.ethz.ch/cvl/DIV2K/). To the knowledge of the authors,...

Dual-Energy Medical CT in Carbonate Rocks

Rodolfo A. Victor & Masa Prodanovic
Carbonate whole cores used to test new methodology for dual energy X-ray CT inversion.

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%.
