Nexen is investigating why its “failsafe” leak detection system failed to detect what turned out to be a massive spill that leaked 5,000 cubic metres of bitumen, sand and wastewater into an area of northern Alberta so remote the oil and gas company needs to build roads from scratch just to access the spill site.
