Advances in Understanding Fault Systems through Scientific Drilling
Session ID#: 249502
Session Description:
Scientific drilling provides access to study in-situ conditions of the subsurface and deployment sites for at-depth instrumentation to sample travel paths different from surface-only deployments. Recent and ongoing drilling projects have targeted active fault zones and geothermal systems, and long-term borehole observatories provide insight into local and regional seismic activity and stress states.We welcome research from a broad range of borehole-related studies including fault zone dynamics, geothermal and fluid migration, borehole geophysical observations (passive and active seismic, distributed acoustic/thermal/strain sensing), lithostratigraphic studies, and mechanical/hydrologic properties of borehole samples, from drilling projects such as the Deep Fault Drilling Programme, Frontier Observatory for Research in Geothermal Energy, Hawai’i Scientific Drilling Project, and the Source Physics Experiment, as well as projects in the planning phases. We particularly encourage interdisciplinary submissions exploring how petrophysical properties, stress distribution and conditions at depth (temperature, fluid pressures and chemistries), and fault zone materials influence one another.
