EnergeÔ starts drilling at Vinzel geothermal site

EnergeÔ has started drilling of the first well at the Vinzel geothermal site in Switzerland with a target depth of 2300 meters. This will take approximately 60 days. The site at Vinzel had been identified as having a high potential for geothermal after a three-week seismic survey across 30 municipalities in the Nyon and Morges districts. The current plan is to drill to target the Dogger formation. Upon completion of the first well, flow and temperature tests will be done to confirm the viability of the resource. A decision will then be made on the drilling of a reinjection well. Completion is expected by summer 2023.

The forecasts based on existing data is a resource with temperatures between 80 to 85°C and flowrate between 30 to 60 liters per second. This resource will make it possible to heat 1500 to 3000 households for at least 40 years.

Upon completion, it will be the responsibility of EnergeÔ to build the “geothermal loop” with surface facilities and heat exchanger. The second circuit will be the responsibility of a company called ThermorésÔ.
