DESCRIPTION
A series of graphs and maps detailing production of shale gas and shale oil (tight oil) in the US, based on an analysis of over 63,000 wells in every shale play in the country.The full report can be found at shalebubble.org/drill-baby-drill.

Overall field decline for the Eagle Ford play based on production from wells drilled prior to 2011
(data from DI Desktop, HPDI, September, 2012)
Overall Field Decline = 27%
The actual overall field decline is likely steeper than shown as many pre-‐2011 wells were being connected over the subsequent months as indicated by the rising well count in 2011 and 2012. If the 27 percent rate is accepted, it would require 723 new wells producing at 2011 rates to offset field decline each year from current produc/on levels.
