There is no evidence from the top three oil producers (Saudia Arabia, Russia and the U.S) that their production will be even close, in total, to current levels by the end of the decade.
Now there comes an Energy Study from Harvard which boldly states that this is rubbish – that by 2020, global production will be at 110.6 mbd and these concerns that most of us have at The Oil Drum (inter alia) are chimeras of the imagination.
It is therefore pertinent to begin with examining where the study (which was prepared with BP assistance) anticipates that the growth in supply will come from.
