Better manage that debt carefully. The 30 year price of oil subsequent to WW2 adjusted for inflation was very stable at $20-22 bbl.  Erratic prices historically began when the OPEC nations decided to cartel the price (supply management).  Today, with many more players in the gig, and significant new technologies for finding and mining oil, the world is experiencing an abundance of oil and the resurgence of market competition pricing.  Cenovus is lucky to see $45 bbl at this time as opposed to a return to $22 bbl, a price that oil companies were making good money at those decades ago.
