Location of deep boreholes exemplary for the region around Hannover (Lower Saxony). The boreholes have different ages and development status (data from NIBIS map server; https://nibis.lbeg.de/cardomap3/). The marked areas are representative of selected target areas for investigations in the project. Most of the wells in the figure are abandoned wells, which in Germany are usually filled former production or exploration wells of the hydrocarbon industry
