After two failed makes an attempt, productive flowrate and temperature have been reported on the Kirchweidach-Halsbach geothermal undertaking in Germany.
The corporate Naturwärme Kirchweidach-Halsbach GmbH & Co. KG has reported profitable outcomes after the drilling of a geothermal borehole close to the Waldweinacht website in Halsbach in Bavaria, Germany. After intensive testing, the properly has been discovered to provide thermal water at a temperature of over 107 °C and a circulate fee of over 100 liters/second.
Drilling for the undertaking began again in January 2023, initially concentrating on a depth of 3500 meters. This was reached in Could 2023, however properly testing indicated that the flowrate of the properly didn’t help business operations though the temperature was sufficiently excessive at 125 °C. A choice was then made to drill a sidetrack properly into one other pre-defined goal. The sidetrack properly was additionally not commercially productive.
After intensive analysis and evaluation of the drilling knowledge, a second sidetrack properly was drilled, concentrating on the Hochscholle area of the Malm aquifer. This lastly resulted within the hoped-for productiveness. The measured drilling depth was 4750 meters at a complete depth of 3050 meters.
The subsequent step for the undertaking would be the drilling of the reinjection borehole. On the floor, the 2 wells will solely be 10 meters aside. On the subsurface, the underside of the wells might be spaced round 1 kilometer aside to stop thermal breakthrough.
Naturwärme Kirchweidach-Halsbach was based as a joint undertaking between the businesses Präzisionsbau Steiner and Biohof Kirchweidach, along with the municipality of Kirchweidach. The geothermal undertaking is supposed to provide warmth to the greenhouses of the 2 corporations, in addition to the municipal district heating community.
Kirchweidach can also be the positioning of the primary Kirchweidach geothermal undertaking, a mixed warmth and energy (CHP) that began with greenhouse heating operations in 2013. The undertaking was then modified with geothermal energy technology via modular energy models in 2019 and a 4-MW binary system in 2020.
