In this presentation, I provide the results of analyzing seismic activity in the northern Montney Play of British Columbia in 2015 and its connection with fluid injection. Using an industry-provided earthquake catalog, spatial and temporal correlation of serismic activity with the fluid injection was investigated. Moreover, some depth constraints were obtained on the events close to the operations with a best-fit moment tensor solution for the largest event. Ground motion from the Mw 4.6 event clipped the seismic sensors at distances up to ~40 km from the epicenter indicating large ground motion amplitudes for an event of this size.


Ali Mahani (Ph.D., P.Geo.) is a seismologist with expertise in ground motion analysis and seismic hazard assessment. He is currently the project seismologist for Induced Seismicity Monitoring Project in northeast BC. He has presented his works in several journals and conferences including Bulletin of Seismological Society of America, Seismological Research Letters, and American Geophysical Union.
