Guelph Dolomite characterization

Andres Gonzalez Hasan Khan
This project is part of a Guelph dolomite (GD) petrophysical characterization study. Multi-scale CT scans are conducted on a GD core (30 mm x 75 mm) at a resolution of 23 um. Medical CT (low resolution - 250 microns), permeability and NMR study are also done on the sample. Digital sub-sample is created and vug have been segmented. Vug characterization is attempted by using the surface to volume ratio to determine the vug shape and...

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.

Guelph dolomite

Gary Pope Hasan Khan
Medical CT scans of Guelph dolomite for fracture characterization. The core was imaged in Department of Petroleum and Geosystems Engineering, UT Austin.

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. This dataset comprises of organised 2D slices and 3D volumes of Bentheimer Sandstone [sourced internally from UNSW] and Estaillades Carbonate [https://www.digitalrocksportal.org/projects/58/origin_data/209/], imaged at a resolution of 3.8 and 3.1 microns respectively. 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,...

Fracture in granite

Richard Ketcham, Matthew Colbert, Jia-Qing Zhou & Bayani Cardenas
High-resolution X-ray CT scans and processing of fracture in granite for modeling 3D fracture flow. Primary fracture mapped using IPSF method.

Bidisperse sphere packs generated under gravity

Hugh Daigle Abhishek Bihani
Bidisperse sphere packs were generated under the effect of gravity to model mudrocks and study the petrophysical properties consisting of small (clay) and large (silt) grains. Multiple, periodic, dense, bidisperse sphere packs were created with large grain volume concentrations (VL) increasing from 0 to 100 %. This was done for large to small grain radius ratios of 2:1, 5:1, 7:1, and 10:1 with constant sphere pack length 10 units in x, y, z directions. The...

Downscaling-based segmentation for unresolved images of highly heterogeneous granular porous samples

Ilenia Battiato Svyatoslav Korneev
We propose a simple and efficient algorithm of downscaling followed by segmentation to reconstruct the unresolved pore space from X-ray computed tomography (XCT) images of natural geological porous media columns. Contrary to widely employed single and multilevel threshold-based segmentation, the proposed method is based on a continuous map between pixel intensity and local pixel porosity that does not rely on the definition of arbitrary thresholds. The approach is used to generate a high-resolution binary 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...

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.
