Descriptions
A stress test campaign was undertaken during the completion of the geothermal doublet on TU Delft Campus (Geothermie Delft), in November of 2025. Cased-hole stress tests (micro-frac tests) were acquired in the reservoir section of the injector (DEL-GT-02-S2), after perforation, to determine the stress state before cooling. These measurements are rarely done in geothermal projects.
