Independent panel review of the Canadian natural Primrose flow to surface causation report

In 2013, there have been four Flow to Surface (FTS) events at Canadian Natural’s Cyclic Steam Stimulation (CSS) operation at Primrose. The bitumen seeped into a lake, muskeg and the forest for more than a year, killing wildlife and polluting the landscape.
As it turned out, industry-induced fractures penetrated “generally impermeable shales” and passed through groundwater before erupting to the surface more than 500 metres away from the originally targeted zone in the Cold Lake oilsands region of Alberta, thus creating unintended pathways and uncontrolled seepage of hydrocarbons to the surface.
