The Globe and Mail reports in its Tuesday, March 22, edition that the Alberta Energy Regulator said on Monday it is implementing additional requirements at Canadian Natural Resources' Primrose oil sands project after concluding excessive steaming caused a 6,648-barrel bitumen-emulsion leak in 2013. A Reuters dispatch to The Globe reports that the requirements include permanent limits on the steam volumes the company is allowed to use to extract bitumen from underground reservoirs, and a requirement that CNRL seek approval for each steaming cycle at its Primrose East site. AER vice-president Kirk Bailey says: "The restrictions do amount to a permanent ongoing reduction in the intensity of the company's operations. The company will not be able to pursue its original operating strategy at Primrose." CNRL has been operating under steam restrictions at Primrose since the seepage was discovered in July, 2013. Bitumen emulsion was discovered oozing to the surface at two locations at CNRL's Primrose project in Northern Alberta in May, 2013. Two more leaks were discovered over the next month, prompting the AER to impose restrictions on the site and launch an investigation.
