Utah FORGE: Laboratory Fault Reactivation and Permeability Evolution During Fluid Injection
This dataset contains results from controlled shear reactivation experiments performed on cylindrical Westerly and granitoid granite samples with a single inclined fracture. Laboratory faults were pre-loaded near failure and reactivated by fluid injection to examine relationships between permeability and induced seismicity. Experiments were conducted under zero displacement or constant shear stress boundary conditions, with upstream pore pressure incremented stepwise while downstream pressure was held constant or at a fixed differential. Deionized water was used as the working fluid. Shear displacement, fault permeability, and acoustic emissions were recorded throughout reactivation, capturing both mechanical and seismic responses. The dataset includes calibrated acoustic emission (AE) records and mechanical measurements documenting changes in flow and shear behavior following each reactivation event. Fault shear displacement was measured together with AE from the calibrated PZT sensors located at the sample end. Passive AE signals were recorded downstream in this study.
