In subsurface resource development, rock fractures serve as primary fluid pathways. Therefore, accurately understanding the dynamic behavior of fractures under coupled thermo-hydro-mechanical (THM) conditions is essential for improving resource estimation and productivity forecasting. This study focuses on shear slip along pre-existing rock fractures—commonly associated with seismic events—and investigates its impact on the mechanical and hydraulic properties of fractures. The evaluation is primarily based on laboratory rock experiments conducted under controlled conditions, and the results provide insights into the role of fracture slip in subsurface environments.
