The most recent heat flow map of the Swiss Molasse Basin dates back to 1995. Since then, several new temperature measurements in (deep) boreholes were conducted. For the aimed energy transition, with the search for deep geothermal energy and CO2 or H2 storage formations, the exploration and understanding of the deeper subsurface is has become much more important . Heat flow is just one fundamental element for that.
The project is based on an earlier study (2019-2021) that already compiled and analysed temperature data from deep boreholes in the Swiss Molasse Basin area. That analysis provided good constraints on the temperature distribution down to 2 km. These intermediate results will provide a strong basis for the next project stage aiming at establishing an interpolation procedure for the calculation of the steady-state conductive heat flow and finally a new heat flow map of the Switzerland.
