As much as three geothermal wells for heating will likely be drilled on the web site of the Laakso Joint Hospital in Finland beginning spring 2025.
Laakso Joint Hospital has signed an settlement for the drilling and end-to-end supply of a geothermal nicely for heating with Hanjin D&B (Drilling & Boring). Drilling of the primary nicely start by spring 2025. If the primary nicely is profitable, two related wells will likely be ordered below the identical settlement.
The goal depth for the wells will likely be 3000 to 35000 meters. Along with the drilling work, the contractor will ship the nicely design, take a look at runs, and coaching for the shopper’s representatives. The full worth of the settlement is EUR 14.5 million, of which the primary nicely accounts for EUR 5.9 million and the subsequent two wells for EUR 4.3 million every.

The water hammer drilling expertise developed by South Korean Hanjin D&B is especially appropriate for this objective. As soon as efficiently accomplished, it is going to be one of many deepest geothermal wells to have been drilled in Finland so far, and the deepest drilled with a water hammer expertise in Europe.
“Geothermal wells are perfect for a densely constructed metropolis — a deep nicely doesn’t take up area and it generates an unsurpassed quantity of native environmentally pleasant power in comparison with generally used geothermal heating. As with every new expertise, it does contain dangers, in fact, with regard to points similar to bedrock high quality at nice depths and the warmth manufacturing capability of the finished nicely. These dangers will likely be managed below the settlement,” mentioned Sari Hildén, Chair of the Board of actual property firm Laakso Joint Hospital.
