Oil companies were not profitable in 2013 when oil was $100 per barrel. The investment required to maintain existing production levels has been increasing at about 17% per year because the oil that’s left is harder to get. Oil companies today need $130 per barrel to be profitable but the price is $60 because consumers cannot afford $130 oil.
We can expect trouble.
