Canadian Natural Resources said on Tuesday its Horizon oil sands operation has resumed production after a seven month gap caused by a fire. The Calgary-based company said expects to reach full capacity of 110,000 barrels per day of syncrude – a light oil manufactured from bitumen – by next week. The Horizon outage led to a shortage of syncrude which helped Alberta’s producers attract a premium of $18 above benchmark US oil.

Western Canada Select in turn trades at $13 a barrel below US levels which on Tuesday was $84 a barrel.
