Much of the cost for Canadian oil sands are fixed costs and once these costs are incurred production increases can take place over decades say Canadian oil sands company executives. CFO Corey Bieber of Candian Natural, says costs at it large Horizone mine are at $37.13 Canadian dollars per barrel in Jan 2015. He expects to cuts costs by at least $10 Canadian dollars per barrel by higher volume production cutting the operating expenses. Increasing production says Bieber does not mean adding people. As a result most of the Canadian oil sands producers can operate at oil well below US$47 a barrel, as low as $30, and are increasing production in 2015. This means Saudis will have to face competition from Canadian oil. It also means the Keystone pipeline will still be needed to transport Candian heavy oil to Gulf Coast refineries in the U.S. Suncor, the largest Canadian oil-sands producer, is increasing capital spending to C$7.2 and output by 11% in 2015. Canadian Natural is increasing production by 7%, and Syncrude Canada Ltd. is planning a 6% increase for 2015....
