N2 - The presence of pre-existing faults and fractures in the upper crust contribute to induced seismicity as a result of fluid injection, in hydraulic fracturing, deep storage of CO2, and stimulation of EGS reservoirs. In all of these, either maintaining the low permeability and integrity of caprocks or in controlling the growth of permeability in initially very-low-permeability shales and geothermal reservoirs are key desires. We explore styles of permeability evolution using both experimental and computational methods to explore how fracture permeability changes in response to fracture/fault reactivation and investigate the roles of (1) mineralogy and (2) fracture roughness in conditioning response; together with (3) intrinsic controls of healing on the earthquake cycle and permeability evolution.
