The decision to move to a SAGD-only operation was described as "entirely economic," and will result in about 350 staff layoffs, most of which will be completed by the end of 2016.

This was caused because of pipeline design incompatible with the muskeg ground conditions, and steps that could have been taken to mitigate the potential for buckling were not addressed. , S; _$ _; H! p! x( y% O* b% I& B9 N

The spill poured up to five million litres of emulsion - a mixture of water, bitumen and sand - into surrounding muskeg. The spill may have been ongoing for up to two weeks when it was discovered in July 2015 by a contractor walking through the area.

In August the Alberta Energy Regulator ordered Nexen to shut down 95 pipelines until the company could prove the pipelines could be operated responsibly. The suspension was lifted in September 2015. 1 p; E5 ^. {4 c
