Eagle Ford - update through September 2017

This interactive presentation contains the latest oil & gas production data from 19641 horizontal wells in the Eagle Ford region (TRRC districts 1-4), that started producing since 2010, through September 2017.

After extreme weather events in August, production in September has mostly recovered in the Eagle Ford to pre-Harvey levels. This is not yet visible in the above graph as production data for September was not yet published for a number of operators and leases, most notably for ConocoPhillips (which operates ~100 kbo/d production from horizontal wells).

In the “Well quality” overview we can see that since 2014 the average well performance has not changed much. A bit more oil is recovered in the initial phase, as well as more natural gas, but the decline curves are very similar. This is unlike the other basins, where we’ve seen larger improvements in the past 2 years.

The ‘Advanced Insights’ presentation is displayed below:



In this “Ultimate Recovery” overview the relationship between production rates, and cumulative production is revealed. For example, by following the orange curve, you can see that the wells that started in 2014 have on average recovered ~132 kbo after 3 years on production, and are now at rate of 45 bo/d. By switching ‘Product’ to gas, you’ll find that in addition these wells have produced ~0.5 Bcf of natural gas.

The 4th tab (“Productivity ranking”) ranks operators by the average performance of their wells. Of the major operators (> 100 wells), Devon & ConocoPhillips  show the best results, as measured by the average cumulative oil production in the first 2 years. If you hover your mouse over (or tab on) the results for Devon, you can see that it has 754 horizontal wells that already have produced for at least 2 years, and that on average they recovered 213 thousand barrels of oil in the first 24 months.

Around the middle of next week I plan a new post on all 10 covered states in the US.

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 data reports.
  • FracFocus.org


The above presentations have many interactive features:

  • You can click through the blocks on the top to see the slides.
  • Each slide has filters that can be set, e.g. to select individual or groups of operators. You can first click “all” to deselect all items. You have to click the “apply” button at the bottom to enforce the changes. After that, click anywhere on the presentation.
  • Tooltips are shown by just hovering the mouse over parts of the presentation.
  • You can move the map around, and zoom in/out.
  • By clicking on the legend you can highlight the related data.
  • Note that filters have to be set for each tab separately.
  • The operator who currently owns the well is designated by “operator (current)”. The operator who operated a well in a past month is designated by “operator (actual)”. This distinction is useful when the ownership of a well changed over time.
  • If you have any questions on how to use the interactivity, or how to analyze specific questions, please don’t hesitate to ask.
