Initially sceptical about peak oil predictions, he was persuaded by Colin Campbell of the unreliability of oil reserves data and the risks this posed to energy supply projections. His insight was to recognise that future production flows, rather than oil reserves, were the key determinant of global oil supply. Consequently, he developed Peak Flow Analysis based on the future oil flows identified in his own Global Oil Megaprojects Database. Using this methodology he concluded that major supply/demand imbalances would occur by 2007 with actual peak oil flows occurring no later than 2011.
