Bericht zum Bohrlochtemperatur-Logging und zu Messungen thermisch-hydraulischer Gesteinskennwerte an Bohrkernen für die Geothermiebohrungen Gt Schwerin 6/17 und Gt Schwerin 7/20 (Schwerin, MV)

This report summarizes the measurements carried out by the GFZ Potsdam on the boreholes Gt S 6/17 and Gt S 7/20 in Schwerin (Mecklenburg-Western Pomerania). The first part of the report describes the borehole measurements of the unperturbed temperature profiles. The second part describes the compilation of the thermal-hydraulic rock properties (thermal conductivity, porosity, permeability, density, etc.) measured on drill-core material. The shut-in time since the drilling is around 4 years for Gt S 6/17 and around 21 months for Gt S 7/20. Hence, unperturbed borehole temperatures are assumed at the time of temperature logging.
