The AER says hydraulic fracturing operations targeting the Duvernay underground formation or deeper are prohibited within five kilometres of the Brazeau dam infrastructure.
Oilfield firms that engage in hydraulic fracturing within five kilometres of the dam must report any seismic events greater than 1.0 magnitude and operations must cease if any event of 2.5 magnitude or greater is detected, the AER says. A 4.6 magnitude earthquake a week earlier was felt in Red Deer and Sylvan Lake in central Alberta and prompted the AER to order producer Vesta Energy Ltd. to suspend fracking at its well site, report all previous seismic activity and file a plan to eliminate or reduce future seismic activity from fracking.
