Imperial Oil Ltd. says it is still investigating the cause and impact of a pipeline spill in the Northwest Territories that has some residents downstream concerned about the potential impact. The Calgary-based oil and gas company reported on July 27 that it discovered about 55,000 litres of produced water had spilled before it shut down the pipeline in Norman Wells, N.W.T.
Pipeline spills about 400,000 litres, some enters North Saskatchewan River
Contaminated water that leaked from an oilfield pipeline on Christmas Day has entered the North Saskatchewan River but has had no detectable impact on it, says a spokesman for Calgary-based oil and gas producer ARC Resources Ltd. The spill was reported by a local landowner at about 2 p.m. last Friday, said Sean Calder, ARC's vice-president of production, in an interview on Tuesday. "We had guys on site within about an hour and then the pipeline was shut in by 4 p.m., I believe," he said.
