High resolution reservoir characterization using induced seismicity and state of the art waveform processing techniques

摘要

Passive seismic monitoring (PSM) is a well-established but still widely underestimated technique to characterize processes occurring in any type of geo-reservoir (geo-thermal, hydrocarbon,. CO_2 storage and unconventional gas). Despite the great" potential of the method, state-of-the art seismological techniques applied to natural seismic events have not yet been widely applied in geo-reservoir monitoring (Bohnhoff et al., 2010). There are numerous studies using PSM and various processing techniques to characterize and understand physical processes governing induced seismicity in different types of geo-reservoirs (Majer et al., 2007; Bohnhoff and Zoback, 2010; Kwiatek et al., 2010, 2013; Evans et al., 2012; Albaric et al., 2013; Goertz-Allmann et al., 2013; Martinez-Garzon et al., 2013). Their overall purpose is to passively monitor if not mitigate the seismic hazard related to the occurrence of induced seismicity (IS) and to develop strategies for safe and efficient reservoir stimulation and exploitation.
