Resource Insights (2012): "It's wrong not because the range quoted above can't be found in official sources. It's wrong because the numbers include things which are not oil such as natural gas plant liquids and biofuels. If you strip these other things out, then world oil production has been running around 75 mbpd this year. The main thing you need to know about the worldwide rate of production of crude oil alone is that it has been stuck between 71 and 75 mbpd since 2005 (calculated on a monthly basis). And, that has already had huge negative effects on the world economy and world society through high energy prices that are partly responsible for our current economic stagnation."
