InSituMetrix to Launch First Pilot at Mont Terri Underground Laboratory
InSituMetrix is proud to announce the signing of an official agreement with the Mont Terri Underground Laboratory to conduct the company’s first field pilot of its in-situ stress measurement technology. Scheduled for 2025, the pilot represents a pivotal step toward the real-world validation of a breakthrough instrumentation solution designed to transform how subsurface stress is measured and understood.
Unlike conventional techniques that rely on hydraulic fracturing and indirect assumptions, InSituMetrix’s technology enables direct, non-invasive measurement of the full stress tensor — including maximum and minimum horizontal stress, as well as vertical stress. While vertical stress is typically derived from overburden calculations, our ability to measure it directly allows for in-situ calibration, improving overall accuracy and confidence in the stress profile — especially in complex geological settings.
“This project marks a turning point for InSituMetrix,” said Angelica Tuttolomondo, CEO and founder. “The Mont Terri pilot offers us the opportunity to demonstrate the precision, reliability, and field-readiness of our technology in one of Europe’s most respected underground research facilities.”
Located in the Jura Mountains of northwestern Switzerland, the Mont Terri Laboratory is an internationally renowned center for research on deep geological repositories and underground engineering. Its controlled environment and multidisciplinary infrastructure provide an ideal testbed for advanced instrumentation.
The project is supported by a group of respected institutions:
BGR (Germany’s Federal Institute for Geosciences and Natural Resources) and TotalEnergies are providing financial support.
swisstopo (Swiss Federal Office of Topography) is contributing institutional and operational support, reinforcing the collaborative and applied nature of the work.
The outcomes of the pilot will support future deployments in energy geotechnics, carbon capture and storage (CCS), hydrogen storage, and deep geothermal energy — applications where accurate stress measurement is essential to design, safety, and regulatory approval.
InSituMetrix is currently seeking additional partners for upcoming field opportunities in 2026 and beyond.
