Fluid‐induced slip on a rate‐and‐state fault during co‐ and post‐injection: The interplay of fluid pressure diffusion and poroelastic stress

Subsurface fluid injection, widely employed in enhanced geothermal systems, CO₂ geological storage, and unconventional hydrocarbon extraction, can reactivate pre‐existing faults and induce seismicity. We present a physics‐based numerical framework that integrates fluid pressure diffusion, poroelastic stressing, and...
