Short summary
This presentation discusses a series of in situ experiments of fault activation by fluid injection conducted in argillite rock at the Mont Terri underground research laboratory in Switzerland to better understand whether pressurization of natural faults can lead to their reactivation and permeability generation in case such features are present near disposal tunnels. Lessons learned from these experiments help inform the safety assessment of geologic disposal in argillite host rock.
