"Total world liquids production as reported by the EIA had reached 85.2 million barrels a day [in mid-2005] ... It briefly passed that level again in June 2006 and June 2008, though mostly was flat or down over 2005-2009 before resuming a modest and erratic climb since then. The most recent number (December 2012) was 89.3 million barrels a day, 4 mb/d higher than where it had been in May 2005 ...
But more than half of that 4 mb/d increase has come in the form of natural gas liquids-- which can't be used to make gasoline for your car-- and biofuels-- which require a significant energy input themselves to produce. If you look at just field production and lease condensate, the increase since May 2005 has only been 1.7 mb/d ... [R]ecent Saudi cutback may have been a deliberate response to U.S. production gains in an effort to prevent oil prices from declining ... [T]hose who assured us that Saudi production was going to continue to increase from its levels in 2005 are the ones who so far have proved to be dead wrong."

Anmerkung: An dieser Stelle sei darauf hingewiesen, dass - trotz der verzweifelten Versuche, kurzfristig die Gesamtölproduktion ["All Liquids"] durch unkonventionelle Kohlenwasserstoffquellen zu maximieren - die konventionelle Rohölproduktion spätestens seit 2005 weltweit rückläufig ist - mit allen weltwirtschaftlichen und geopolitischen Konsequenzen.
