Improving geothermal doublet efficiency in multiple sandstone horizons in Hannover/GermanyNARA Subscribed
Grundwasser · 2025 · Vol. 30 · Issue 1 · Springer
Jonas Suilmann; Torsten Tischner; Thomas Graf
In Hannover, Germany, a deep borehole was drilled to explore the use of geothermal energy for the heat supply of office buildings. The targets are multiple subdivided sandstone horizons of the Wealden formation (Lower Cretaceous) at a depth of 1200–1300 m and a temperature of around 70 °C. The technical feasibility of the doublet operation is assessed by numerically investigating the effects of well spacing, injection/producti...
