In Libya strikes by oilfield workers have reduced daily production of crude oil dramatically from 1.6 million barrels a day to an estimated 250,000 barrels a day. In Iraq there have been bombings of pipelines which have interrupted production and promise to put a cap on Iraq’s ability to increase oil production. In Nigeria production has fallen by 10%  daily due to leaks caused by the plundering of the oil by political trouble-makers.
