Spatial Quantification of the Diffusion of Fluids Containing 1H in the pore system of rock cores
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.
