Multimineral Model

Description

A North Sea sandstone with 23% porosity and 640 mD permeability was cleaned with solvents, dried at 60°C, and imaged using micro-CT at a 2.3 μm resolution over 22 hours. It was then cut, resin-impregnated, polished, and carbon-coated for 2D mineral mapping using SEM-EDS with QEMSCAN at a 2.0 μm resolution. The 2D mineral map was registered to the 3D micro-CT image, and minerals were segmented into seven groups based on X-ray intensity, though some minerals with similar attenuation could not be fully distinguished. The data is uploaded as 4 netCDF blocks that combine into a full 3D data set of 1,000^3. Full details are provided in the netCDF header files. The segmented domain is associated with LBPM (https://github.com/OPM) simulations results available at https://zenodo.org/records/13836047
