X-ray micro-tomography dataset of Ketton carbonate

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.
