The B.C. Oil and Gas Commission has shut down oilfield fracking operations for at least 30 days in northeastern British Columbia while it investigates earthquakes that occurred there on Nov. 29.
The regulator says the seismic events, which measured between 3.4 and 4.5 magnitude, took place near hydraulic fracturing operations being conducted about 20 kilometres southeast of Fort St. John by Calgary-based Canadian Natural Resources Ltd. Frac – The practice is also known as fracking.
Honn Kao, a seismologist with Natural Resources Canada, told CBC’s Daybreak North that most fracking operations don’t produce induced earthquakes, and when they do, they’re relatively small and shallow.
