I am a groundwater modeler (hydrogeologist) and often work in fractured rock (mainly for mining clients). No experience with modeling for hydrothermal projects though. While the physics of modeling fluid flow in these environments is possible (e.g. discrete fracture networks), mapping and having confidence in the distribution and actual inter-connectivity of the fractures (i.e. preferential flow pathways) is incredibly difficult.

Is the difficulty because the sensing techniques give general but not-localized results? I.e. porosity in an area, but no information about specific connected fissures? Or something else?

My cousin is in hydrogeology as well! Fascinating subject!

What is the accuracy of the mapping you do and is it destructive? Do you deal with hot systems (steam/water equilibrium matters)?
