Another Industry Reported Quake in BC’s Fracking Grounds\u2028<\/a><\/h3>\n

Regulator says tremor likely industry-caused, but company says it’s too soon to say.<\/strong><\/p>\n

Progress Energy, an arm of the Malaysian oil company Petronas, temporarily shut down operations at a wellsite after a 4.5 magnitude earthquake hit an area 114 kilometres northwest of Fort St. John on Aug. 17.<\/p>\n

B.C.’s oil and gas regulator\u00a0said<\/a>\u00a0the earthquake was likely caused by hydraulic fracturing but “has yet to determine the cause of the event.” Progress Energy reported the tremor on Monday. No damages were reported to the regulator.<\/p>\n

“The Commission is working to obtain a reasonable event depth from local seismic-monitoring data and is collecting more information about the event as part of its investigation,” B.C. Oil and Gas Commission spokesman Allan Clay told The Tyee.<\/p>\n

David Sterna, Progress Energy’s director of external affairs, said the company has since resumed operations with approval from the regulator, and that “despite certain media speculation, it is too early to determine whether Monday’s seismic activity was a natural occurrence or related to hydraulic fracturing activities.”<\/p>\n

The epicentre of the earthquake occurred three kilometers from a site where Progress Energy was conducting a multi-stage frack into the Montney Shale, a large swath of land stretching across northeast B.C. into northwest Alberta.<\/p>\n

In B.C., any fracking operation that measures a magnitude 4.0 tremor or greater within a three kilometre radius of the drilling pad must report the event to the regulator and suspend operations. Alberta operates a similar “traffic light” system for earthquakes in the Duvernay Shale around Fox Creek, Alberta.<\/p>\n

That region, which has\u00a0experienced<\/a>\u00a0industry-made quakes for two years, saw\u00a0a 2.6 tremor in early August.<\/p>\n

The shale gas industry injects fluids and sand at high pressure into deep and shallow wells to crack open difficult oil and gas deposits. The injections create a network of cracks that can also connect to water zones, other industry wellsites and faults.<\/p>\n

The reactivation of these faults can then trigger an earthquake, sometimes days after the fracture treatment, scientists say.<\/p>\n
