- Induced Seismicity Risk Management Strategies: Montney Case Study | Presentation/Poster
Change of in-situ stresses due to hydraulic fracturing activities may induce earthquakes on critically-stressed faults when pressure pathways exists for communication to the nearby faults. Although such events are mostly small in magnitude and typically generate ground shaking well below the perception threshold, a small number of M>3 events, correlated with fracturing operations, have been observed in western Alberta and north eastern British Columbia. This has raised concerns on potential risks associated with induced
seismicity. Regulatory bodies have mandated risk mitigation strategies to control the associated operational activities. These strategies include induced seismicity monitoring (ISM) programs, which involve the deployment of real-time seismic networks in the vicinity of operation sites. In this study, we present learnings on the management of induced seismicity risk from a 2-year monitoring program of multi-pad hydraulic fracturing site in western Canada.
