Bentheimer sandstone image data

Project Cover Image


This dataset contains tomogram and segmentations of micro-CT acquired Bentheimer Sandstone samples. All samples are segmented into: pore, clay region, quartz, feldspar, and high-density mineral, with the exception of BHG0 for which only the first three phases are segmented. The images are in netCDF format, which can be visualized by 'ncview'. This is free software licensed under the GNU General Public License version 3. In associated publications phase-specific petrophysical quantities significant for the interpretation of NMR relaxation responses, e.g., transverse and longitudinal surface relaxivity, effective diffusion coefficient, and effective transverse and longitudinal relaxation time of clay regions are derived using Inverse Solution Workflows (ISWs) alleviating the computational burden using Bayesian optimization.
