Regional geological recognition for the implementation of a cantonal geothermal concept

In order to advance pre-existing geological models and identify geothermal potential, 4 high resolution reflection seismology profiles were conducted with a weight drop (400kg).

A large team performance ensured high productivity and adequate security when working on roads or in urban environments. One line was acquired on an international airport tarmac and involved significant security measures for our teams.

The resulting sections had a greater investigation depth than the initial goal, which allowed an improved calibration for interpretation.

Reflection seismology is able to highlight geological interface in both quaternary units and bedrocks

Multiple pre-existing seismic lines and boreholes allowed geological interpretation of acquired lines and advancement in pre-existing geological models.
