A seismic marketing campaign Géothermie Préalpes SA will begin this November as a part of a geothermal potential analysis examine in Gruyère, Switzerland.
Géothermie Préalpes SA will probably be conducting an information acquisition marketing campaign as a part of a examine to discover the geothermal potential in Gruyère, Switzerland. All through the month of November 2023, particular autos will journey the roads of the Gruyère district with the intention of mapping the subsoil and assessing the presence of geothermal water.
We had first reported on plans to look at the geothermal potential in Gruyère earlier this 12 months, with partial funding by the Swiss Federal Workplace of Power.
After a preliminary examine revealing an fascinating hydrothermal potential in Gruyère, Géothermie Préalpes SA will perform an information acquisition marketing campaign to higher perceive the subsoil of the area. If the potential is confirmed, Géothermie Préalpes SA might take into account exploiting this native, renewable, clear and protected vitality supply.
Géothermie Préalpes SA hopes to have the ability to verify the presence of usable water tables between 3,000 and 4,000 meters deep. These pure scorching water reservoirs might be used to provide Gruyère Energie’s district heating (CAD). If the temperature of the geothermal water is excessive sufficient, it might even be potential to think about electrical energy manufacturing.
Particulars on the seismic marketing campaign
Waves will probably be despatched by the measurement autos into the bottom which can then be mirrored by the completely different geological layers and captured by units referred to as geophones. The info from this marketing campaign will make it potential to create a subsurface map and higher characterize a possible geothermal useful resource.
Measurements will probably be taken primarily throughout the night time to cut back background noise throughout acquisition and procure extra dependable knowledge. Vibrations could also be felt close to the autos for just a few seconds, then they are going to transfer just a few tens of meters to the subsequent measurement level. On the finish of the marketing campaign, the measuring gear will probably be recovered with out leaving a hint on the bottom.
Information acquisition will happen within the following municipal territories:
- Bulle
- Corbières
- Hauteville
- Pont-en-Ogoz
- Sorens
- Echarlens
- Marsens
- Riaz
- Sâles

- Vuadens
- Bas-Intyamon
- Broc
- Gruyères
- Le Pâquier
- Châtel -sur-Montsalvens
- Crésuz
- Val-de-Charmey
The motion of the measurement autos can be tracked in real-time on the challenge web site.
Through the summer season of 2023, the brokers of Géothermie Préalpes SA contacted the landowners within the exploration space with the intention to request the mandatory rights for the set up of geophones and the passage of measurement autos. As well as, all of the municipalities involved responded positively to the request for the usage of public property for the passage of those cell convoys. The canton of Friborg gave its authorization by granting a floor analysis allow by its decree of March 7, 2023.
After the survey, interpretation of the info collected is predicted to take a number of months. It is going to represent the idea for outlining the subsequent steps which might happen between 2024 and 2027. This may notably contain a second marketing campaign of geophysical measurements over a extra restricted space and a reconnaissance drilling.
