The images in this dataset are a sample of Ketton carbonate from a micro-computed tomography (micro-CT) scan acquired with a voxel resolution of 4.52 µm. This dataset is part of a study on the effects of Voxel Resolution in a study of flow in porous media. A brief overview of this study summarised from Shah et al 2015 follows. A fundamental understanding of flow in porous media at the pore-scale is necessary to be able to upscale average displacement processes from core to reservoir scale. The study of fluid flow in porous media at the pore-scale consists of two key procedures: Imaging reconstruction of three-dimensional (3D) pore space images; and modelling such as with single and two-phase flow simulations with Lattice-Boltzmann (LB) or Pore-Network (PN) Modelling. Here we analyse pore-scale results to predict petrophysical properties such as porosity, single phase permeability and multi-phase properties at different length scales. The fundamental issue is to understand the image resolution dependency of transport properties, in order to up-scale the flow physics from pore to core scale.

Dry scans of small cylindrical Ketton carbonate core (5 mm diameter and 10 mm length) were scanned using a laboratory micro-CT scanner, a Versa XRM-500 X-Ray Microscope (Zeiss X-Ray Microscopy, Pleasanton, CA, USA). To study and analyse the effect of scaled voxel resolution on the pore-scale micro-CT images and corresponding transport properties, it was necessary to scan the sample with the same field of view with respect to change in voxel resolution. X-rays from a micro-focused X-ray source are used to look into the sample. The X-ray source produces a polychromatic X-ray beam and the projection data (3000 projections) were collected with a cone beam along the circular trajectory. The voltage was set at 80 kV and power at 7W. In our cone beam set-up, the voxel resolution is controlled by the proximity of the sample to the beam or X-ray source.
