The Allach Th1 geothermal borehole on the MTU Aero Engines facility in Munich, Germany (supply: Erdwerk)
The primary geothermal borehole drilled on the MTU Aero Engines web site in Munich, Germany has proven good temperature and hydraulic efficiency.
Drilling and pump testing of the primary properly drilled for the geothermal heating venture of plane engine producer MTU Aero Engines AG (MTU) in Munich, Germany has been accomplished, with information thus far indicating a productive properly. The drilling rig will then be skidded to the placement of the second properly, which will likely be drilled by mid-April.
First reported in 2020, the geothermal venture goals to provide course of and house heating for the buildings of MTU, lowering the present fossil gas utilization by as much as 88%. ERDWERK has been managing the venture since 2020, beginning with the fundamental investigation, help within the mining approval course of together with the appliance for the Karlsfeld-Ost allow subject, the feasibility research, detailed planning, and the tendering course of. German drilling firm Daldrup & Söhne AG has been awarded the overall contract for the development of the geothermal doublet.
Drilling for the MTU formally began on the finish of January 2024. With a complete distance of 2650 meters, the primary borehole (Allach Th1) was deviated to the south and hit the Malm formation on the 18th of March after nearly two months of drilling. Mud losses throughout drilling within the Malm have been early indications of fine hydraulic situations.
Brief-term pumping exams indicated a productiveness index (PI) of over 50 L/s/bar at roughly 120 L/s. This makes Allach Th1 one of the vital greatest Malm wells when it comes to hydraulic efficiency within the Molasse Basin. The information obtained thus far signifies a really productive borehole, with an excellent movement fee of properly over 100 liters per second and a temperature of round 70°C.
With this drilling, the superb hydraulic properties of the Malm thermal water reservoir have been demonstrated for the primary time within the northwest of Munich (and on the venture web site of the MTU plant in Munich-Allach).
