Paper about Migration of Fluids through Rocks - PET with CT and MRI comparisions

·       Evaluation of Positron-Emission-Tomography for Visualisation of Migration Processes in Geomaterials

Transport of a fluid through rock depends on the porous or fractured structure of the material. PET can provided a time and space evolution of an injected tracer through a material.  Comparatively high resolution CT yields structural information. NMR can also be used to study process but has a much lower resolution than PET. This study looked at evolution of a flow injected at different rates into the material. At slower speeds there is more lateral dispersion of the fluid through the material.
