Kiskatinaw seismic monitoring report

A recent seismic report says there have been 14 seismic events in the Peace.  

Induced Seismicity Study in the Kiskatinaw Seismic Monitoring and Mitigation Area, written for the BC Oil and Gas Commission was written by Amy D. Fox, Ph.D., P.Geo. and Neil D. Watson, P. Geol.

The study and report that was published by Enlighten Geoscience Ltd following the suspension of the hydraulic fracture operations after a series of three seismic events ranging from 3.4 to 4.5 magnitude in 2018 near the Kiskatinaw Seismic Monitoring and Mitigation Area. (KSMMA)  

“There were 14 associated reports of felt events at the surface, and an active BC Hydro construction site was evacuated as a precautionary measure.” 

The study says induced seismic events have been a growing concern throughout North America, around the world, and increasing numbers have been occurring in historically quiet tectonic areas and appear to be related to localized oil and gas development activity. 

The study included a larger investigation designed to identify key or common factors with induced seismicity and/or to delineate areas of higher induced seismicity likelihood within the KSMMA.

“Data that has been collected in the past, makes it difficult to develop a good understanding of the induced seismicity in the region.”

The study also included proprietary data collation, standardization and quality control/assurance with a limited structural geology, hydrodynamics and geomechanical interpretation. 

Further study is needed to better understand both the state of stress and the distribution of existing faults and fractures in the KSMMA, as well as the implications of the discrepancy between the known seismic events and the most critically stressed fracture/fault orientations. 

The report was written as a preliminary contribution to understanding issues surrounding induced seismicity in the Kiskatinaw Seismic Monitoring and Mitigation Area.

“To aid in the development of standardized pre-assessment methodologies and mitigation protocols,” said the report. 

The ability to predict induced seismicity or infer economic valuations is explicitly not meant to be implied from the report.
