Nuclear magnetic resonance (NMR) is commonly used for the geological, geophysical and petrophysical purposes. The most often NMR utilization is the determination of a rock’s porosity, permeability or wettability. Emerging technologies for NMR equipment opened up the possibility of visualizing porosity using magnetic resonance imaging (MRI). The most common MRI technique for this purpose is single-point imaging, but diffusion-weighted imaging (DWI) is becoming implemented for rocks. This dataset comes from a more advanced technique- diffusion tensor imaging (DTI) for a carbonate rock core sample. We employed this technique in order to attempt a rotationally invariant, voxel-by-voxel quantification of diffusion of fluids in a rock's pore system.
