The OPEC 2015 World Oil Outlook came out a few days ago. They basically produce two outlooks, a medium term outlook to 2020 and a long term outlook to 2040. I found their medium term outlook pessimistic in some cases to optimistic in others. But I found their long term outlook to be wildly optimistic… in most cases.  In all cases below I chart crude when it is available and “liquids” only when no other option is available. The data is in million barrels per day.
