“By our calculations it will require additional debt formation of $39 trillion over the next decade to keep petroleum production operating.  Where that funding will originate from, when it is very unlikely to ever be repaid, will be of tantamount importance.  It will take very strong-willed societies to make such sacrifices.  If those sacrifices are not made, the integrated global production system will have disappeared by 2026.  2016 will be witness to the beginning of this event with dramatically increasing closures and bankruptcies throughout the world’s petroleum industry.
