Regional geological recognition for the implementation of a cantonal geothermal concept
In order to advance pre-existing geological models and identify geothermal potential, 8 high resolution reflection seismology profile lines were conducted with a 50’000 pounds vibrator.
A large team performance ensured high productivity and adequate security when working on roads or in urban environments. One line was acquired by night on a busy road and involved significant roadside security measures.
The resulting sections had a greater investigation depth than the initial goal, which allowed an improved calibration for interpretation.

The investigated depth from the sections in this study was much greater than expected. Information on Triassic and Permo-Carboniferous structures are observed.
