Drilling is currently ongoing for a geothermal project in the municipality of Yverdon-les-Bains in the district of Jura-Nord, Canton of Vaud, Switzerland. The project by Malménergie Naturelle aims to extract water at 45 degrees Celsius from a depth of about 1100 meters to supply heat to the vegetable-producing greenhouses of the family business Stoll Frères SA.
The project has an investment cost of CHF 17.5 million (approx. USD 18.75 million) and is expected to be commissioned by 2023.
Drilling for the project began on November 21, 2022. The plan is to drill two wells to create a geothermal doublet. Both wells will target the middle Malm aquifer, a well-studied aquifer that has already been tapped by the thermal baths in Yverdon-les-Bains and has been productive for several years. Geothermal water is expected to be extracted from this aquifer at temperatures between 45 and 50 degrees Celsius and flow rates of 50 to 150 L/s.
The first well, Montagny-2, is a deviated well that is expected to be completed by December 20. Tests will then be conducted on the well to determine its flow rate and temperature. Results from the tests will help refine the drilling strategy for the second well, Montagny-2, to be drilled by February 2023 from the same well pad.
