Advances in Characterizing Seismic Hazard and Forecasting Risk in Hydrocarbon Systems
Unprecedented seismic activity near hydrocarbon development sites has raised questions regarding the physical mechanisms causing induced seismicity and spurred the expansion of hazard mitigation strategies over the past two decades. Adaptive and data-driven strategies for mitigating seismic hazards associated with hydrocarbon production, rely on real-time monitoring of earthquakes, identification of faults and accurate timely reporting of operational data like downhole pressure. Different kinds of injection and production in operational fields change the reservoir and subsurface stress in space and time. Necessary ancillary data (e.g., sonic logs, 3D seismic data, fault maps and subsurface pressure) are not always publicly available or reported in near-real time. Recent advancements in seismic and geodetic data availability and processing afford opportunities for developing high resolution catalogs and monitoring programs. Such data can be used to drive stress simulations and forecasting scenarios for induced seismicity and the real-time characterization of the evolving seismic hazard that enables stakeholders to make informed decisions on mitigation. 

We seek diverse contributions focusing on hazard mitigation and risk assessment that span disciplines, including insight into the physics of induced earthquakes, the evolution of host faults and rocks, and case studies of successful mitigation. We encourage submissions that showcase innovative datasets made of deep learning, distributed acoustic sensing and large-N arrays, 3D imaging of faults and integrated hydrologic and geomechanical modeling linked to production and injection operational data (including carbon capture sites). Presentations on computational, laboratory and in-situ experiments for understanding fault behavior and fault slip modes under undrained/drained conditions are also encouraged to shed light on hydro-mechanical processes governing the spatiotemporal evolution of micro-seismicity.
