The state of global oil production
”Assuming that the balancing act between declining and growing [oil producing] countries continues (from Mexico through to Canada) the whole system will peak when the US shale oil peaks (in the Permian) as a result of geology or other factors and/or lack of finance in the next credit crunch, and when Iraq peaks due to social unrest or other military confrontation in the oil-producing Basra region. There are added risks from continuing disruptions in Nigeria and Libya, steeper declines in Venezuela and the impact of sanctions on Iran.”
