* the growth rate has been incredible to say the least. Alberta's unconventional light oil plays are under-going a similar revolution at present.
The U.S. Energy Information Administration (EIA) reported that U.S. tight oil production more than tripled over the past three years, from 250,000 b/d at the beginning of 2009 to just under 900,000 b/d in November 2011. The Bakken formation in North Dakota and the Eagle Ford shale in south Texas accounted for 84% of total U.S. tight oil production in November 2011. The EIA noted that while oil output from the Bakken formation is currently about 1.5 times greater than production from the Eagle Ford shale play, oil production in the Eagle Ford increased more than 200% during 2011, while Bakken output rose approximately 45% over the same period.
