This article contains still images from the interactive dashboards available in the original blog post. To follow the instructions in this article, please use the interactive dashboards. Furthermore, they allow you to uncover other insights as well.

This interactive presentation contains the latest oil & gas production data from all 23,030 horizontal wells in the Eagle Ford region, that have started producing from 2008 onward, through May 2019.


Oil production has stayed at a level of around 1.3 million bo/d in the first 5 months of this year, after revisions. Although not all well completions are reported yet, so far the number is lower than last year (688 vs. 809 through May).

An important reason why the Eagle Ford has been struggling can be seen in the “Well quality” tab. Since 2017, well productivity has no longer improved. Normalized for lateral lengths, well results have even slightly deteriorated.

Declines are steep in this area. Of the 17.5 thousand horizontal oil wells that came online before last year, over 10 thousand are currently producing below 25 bo/d. Fewer than 1 thousand of those wells are still producing more than 100 bo/d. In our advanced analytics service, these findings can be analyzed in full detail.

The ‘Advanced Insights’ presentation is displayed below:



This “Ultimate recovery” overview reveals the relationship between production rates and cumulative production. Wells are grouped and averaged by the year in which production started.

Also here you can see that the almost 2 thousand horizontal wells that came online last year are closely tracking the performance of the wells that started the year before. The wells that began production in 2010 have now fallen to an average rate of about 10 bo/d. However, many of these wells are gas wells (switch ‘Product’ to gas to see that).

Production data is subject to revisions, especially for the last few months.

For this presentation, I used data gathered from the following sources:

- Texas RRC. Production data is provided on lease level. Individual well production data is estimated from a range of data sources, including regular well tests, and pending lease reports.
