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%.

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...

Induced rough fracture in Berea sandstone core

Zuleima Karpyn, Christopher Landry & Masa Prodanovic

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.

Pore scale in situ imaging of multiphase flow at steady-state for an altered mixed-wet Bentheimer sandstone

Shuangemei Zou, Yang Liu, Jianchao Cai & Ryan Armstrong
The data sets contains in situ imaged fluid distribitions for two-phase drainage at four fractional flows under steady state condition for a water-wet Bentheimer sandstone and an altered mixed-wet Bentheimer sandstone.

Further details on experimental protocols can be found in Zou (2018,2019). Data was acquired at the University...

X-ray micro-tomography datasets of mixed-wet carbonate reservoir rocks for in situ effective contact angle measurements

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...

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...

Mudrock images from Nankai Trough

Abhishek Bihani, Hugh Daigle, Masa Prodanovic, Kitty Milliken & Javier E. Santos
An image analysis workflow was used to study the electron microscopy images of uncemented muds obtained at various depths (< 1.1 km burial) in the Kumano Basin of Nankai Trough offshore Japan for studying the silt bridging phenomenon. Forty-nine images from five core samples at different depths of Site C0002 obtained during Integrated Ocean Drilling Program (IODP) Expeditions 315 and 338 were used for the study. The original image set can be found at https://www.digitalrocksportal.org/projects/42....

Time-resolved X-ray microtomography non-equilibrium and quasi-equilibrium two-phase flow in glass beads

Dorthe Wildenschild & Douglas Meisenheimer
This project includes 2 time-resolved X-ray microtomography experiments performed in glass bead packs. The two datasets are differentiated by the flow condition controlling each experiment, non-equilibrium (nonEq) and quasi-equilibrium (quasiEq). Each dataset includes segmented images comprising primary drainage (PD), main imbibition (MI), main drainage (MD), and a few scanning imbibition (SI) and drainage (SD) curves. The quasiEq data also includes some interfacial relaxation data. The tomographic images were collected with a 3.2 um voxel resolution...

Decane and brine injected into Estaillades carbonate - steady-state experiments

Catherine Spurin, Samuel Krevor, Martin Blunt & Tom Bultreys
This data is micro-CT images of the simultaneous injection of decane and brine into a porous carbonate rock (Estaillades). The images were acquired during steady-state, which was deduced from a plateau in the differential pressure across the sample. The experiments were conducted in the capillary dominated regime (the total flow rate was kept constant, with the fractional flow (fw) changed in sequence 0.85fw, 0.7fw, 0.5fw, 0.25fw, 0fw). The total flow rate was kept constant at...

3D printing of fracture networks

Anna Suzuki
Conventional experiments using real rock samples have trouble in observing rock structures and controlling fracture properties. Taking advantage of 3D printing technologies, we made a complex fracture network by using a 3D printer. Hydraulic properties, such as porosity and permeability were similar with the theoretical values. A tracer response curve from the flow experiment were compared with numerical simulations.

Zhe Li, James McClure & Thomas Ramstad
The dataset provides simulated two-fluid distributions generated by an open-source lattice-Boltzmann fluid solver LBPM, (https://github.com/OPM/LBPM). Direct pore scale simulations were performed with a Bentheimer sandstone sample uploaded by Laura Dalton (https://www.digitalrocksportal.org/projects/218). The mixed-wet two-fluid flow simulation was initialized from a morphological drainage with a residual water saturation Swi=0.08; all solid voxels in contact with oil were assigned to different wetting conditions while a strongly water-wet condition was assigned to the solid surface in contact with...
