Tomography and hydrogeophysics

In this field of research we develop new techniques for decimetre to meter-scale reconstruction of geological structures relevant for fluid flow and transport. Our tomographic methods are mostly based on multi-level borehole data and recordings to invert aquifer structures. The information processed is manifold such as recorded hydraulic signals, tracer breakthrough curves, temperatures, CO2 or gas pressure or borehole breakouts. We currently develop computationally efficient procedures for tomographic reconstruction of fractured systems, as well as focus on new ways of coupled hydrogeophysical inversion.
