Savonnières carbonate

Tom Bultreys, Jeroen Van Stappen, Tim De Kock, Wesley De Boever, Marijn A. Boone, Luc Van Hoorebeke & Veerle Cnudde
Savonnières limestone is a mono-mineralic, calcitic, layered oolithic limestone belonging to the Oolithe Vacuolaire (France). Its pore structure contains 4 types of porosity: inter-granular and intra-oolithic microporosity, and inter- granular and micro-connected macroporosity (hollow ooliths). The hollow ooliths are only connected to the other macro-pores by microporosity in the oolith-shells. Depending on local variations, the permeability ranges from 115 mD to more than 2000 mD (based on TinyPerm mini-permeameter measurements), and porosity ranges from 22%...

Residual air in air/brine systems

Charlotte Garing, Marco Voltolini, Jonathan B. Ajo-Franklin & Sally M. Benson
The objective of this study was to obtain pore-scale images of residual gas in three different pore structures using X-ray computed microtomography in order to measure gas ganglia capillary pressures using air/brine interfacial curvature measurements. The present data set consists of raw images of air and brine after a gravity-driven imbibition in three samples: a glass bead pack, a Boise sandstone and a Fontainebleau sandstone, acquired with various resolution (2X - 4X/5X - 10X) leading...

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.

Supercritical CO2 - Brine Primary Drainages (40-60C, 8-12 MPa)

Xiongyu Chen, Shuang Gao, Amir Kianinejad & David A. DiCarlo
This project includes porosity images and steady-state water saturation images at 8 different positions (distance from inlet are 4, 12, 20, 28, 37, 44, 52 and 59 cm) along a 60-cm long Berea sandstone core (45 mD) during three primary drainage experiments conducted at 40C & 12 MPa, 40C & 8.3 MPa, and 60C & 12 MPa. The drainage experiment starts with injecting 1:1 volume ratio of CO2 and brine. After steady state is reached,...

Massangis Jaune carbonate

Tom Bultreys, Marijn A. Boone, Tim De Kock, Geert De Schutter, Peter Vontobel, Luc Van Hoorebeke & Veerle Cnudde
The Massangis Jaune variety of the Massangis limestone (France) is an ooid-dominated grainstone containing detrital micrite and bioclasts. Within the bulk of this rock, patches of several cubic centimeters with a different microstructure and a lower porosity occur seemingly randomly (Boone et al., 2014). The bulk, from which the sample used in this work was selected, has a porosity of 11.6% (measured by mercury intrusion porosimetry (MIP) to avoid averaging the porosity of the bulk...

A Multiscale Sandy Microstructure

Peyman Mohammadmoradi
Image stack of a multiscale microstructure including inter- and intragrain pore spaces. This project contains an image stack of 512 2D images creating a 3D multiscale sandy porous medium. The images are segmented with a resolution of 3 micrometers per pixel.

Biofilm Imaging in Porous Media by Laboratory X-ray Tomography: Combining a Non-Destructive Contrast Agent with Propagation-Based Phase-Contrast Imaging Tools

Maxence Carrel, Mario A. Beltran, Veronica L. Morales, Nicolas Derlon, Eberhard Morgenroth, Rolf Kaufmann & Markus Holzner.
X-ray tomography is a powerful tool giving access to the morphology of biofilms, in 3D porous media, at the mesoscale. Due to the high water content of biofilms, the attenuation coefficient of biofilms and water are very close, hindering the distinction between biofilms and water without the use of contrast agents. Until now, the use of contrast agents such as barium sulfate, silver-coated micro-particles or 1-chloronaphtalene added to the liquid phase allowed imaging the biofilm...

Moura Coal

Ryan Armstrong & Peyman Mostaghimi
Two data sets are provided: 1- Dry image of the coal sample (NetCDF format - 1505x1497x80, 16 bit) 2 - Saturated with contrast agent (NetCDF format - 1505x1497x80, 16 bit) Both images are registered to each other.
