Direct measurement of the flow field with GeoPET as the starting point for reactive transport modelling

We present a RTM workflow which is based on the direct experimental derivation of effective volume and velocity vector field from sequential positron emission tomograms (PET) of the tracer transport in geologic materials. The focus on tracer concentration incorporates unconstrained upscaling from molecular sensitivity to the millimeter scale. This workflow allows minimizing deviations from the experiment and computational expenses.
