The CNOOC-owned energy company will only be continuing its steam-assisted gravity drainage (SAGD) operations at Long Lake, after it determined a short-term repair was not possible for the hydrocracker unit, which killed two employees when it exploded on Jan. 15, 2016.

Nexen also said it found the root cause of a July 2015 emulsion spill at Long Lake to be a "thermally-driven upheaval buckling of the pipeline, and the subsequent cooldown during the turnaround."* t" @7 X7 S) G3 J9 `' ], B0 K& y
