Cool Tools for considering Future Bakken Output

Webster Hubble Telescope (WHT) has a new blog called Context Earth with a cloud hosted server with some of his oil reserve models. See the Red Queen tight oil model 2.  This inspired me to create an interactive spreadsheet which does something similar. 

The spreadsheet is called bakken2.xlsx and can be found here on Google Drive.

One difference between WHT’s “red queen tight oil model 2” and my bakken2 model is that the EUR of new wells is about 280 kb in his model and 340 kb for my model at 30 years. 

A second difference is that my model allows the new well EUR to decrease at any annual rate from -0.1 to .99 (10 % increase to a 99 % decrease) starting in Jan 2014 and rising to the maximum monthly rate by June 2015.

Future Bakken Crude Oil Output, Oil Price, USGS Estimates, and Decreases in Well Productivity

Summary Chart ND Bakken/Three Forks Scenarios

There is quite a bit of optimism in the US about potential future crude oil output.  Due to the media reports that the US will become self sufficient in oil output, many Americans believe that oil prices are likely to decline in the future due to the abundance of oil resources.  This view may be too optimistic.

The enthusiasm is based on the success in the North Dakota portion of the Bakken/Three Forks play since 2008. The high oil prices over most of the period from 2008 to 2012 has made the high cost oil from North Dakota profitable. Bakken/Three Forks output in North Dakota has expanded from 43 kb/d in Mar 2008 to 719 kb/d in Mar 2013, a 16 fold increase over 5 years. The media believes these increases will continue, but the rate of increase is slowing considerably.
