Visualizing US shale oil production, Eagle Ford – update through December 2016
https://shaleprofile.com/index.php/2017/04/04/eagle-ford-update-through-december-2016/
This interactive presentation contains the latest oil & gas production data from 18858 horizontal wells in the Eagle Ford region (TRRC districts 1-5), through December 2016.
Oil production in this region kept falling in December, and came in just below 1050 kbo/d. As you can see from the light blue area, production from all wells that started before 2016 declined during 2016 from 1440 kbo/d to 675 kbo/d. This means that the overall annual decline rate was just above 50%. For gas this metric was a little less steep (just above 40%). Future revisions will increase the displayed production numbers for the last few months a bit.
The production profiles for all these wells are shown in the “Well quality” overview. The rather straight shape of these curves, on a semi-log plot, indicate a close to exponential decline rate.
The top graph in the “Well status” overview shows the number of new horizontal wells put on production each month in this region. The major pullback since late 2014 is visible, as the monthly new well additions dropped to a level of about 100 wells a month, which was last seen in 2010 when the Eagle Ford just started to boom.
The performance of the largest operators is visualized in the last tab (“Top operators”). Here you’ll notice that Devon Energy increased production significantly in the final month of 2016, but still ended the year about 1/3rd lower.

Really nice interactive graphs, maps and the like at the link.
