Eagle Ford - update through April 2018

This interactive presentation contains the latest oil & gas production data through April from 20,207 horizontal wells in the Eagle Ford region, that started producing since 2008.

Despite significant future upwards production revisions, which are typical for Texas, it appears that total oil and gas production has declined in the Eagle Ford since December.

It also appears that the wells that started producing in 2018 are so far closely tracking the performance of wells from last year (see the ‘Well quality’ tab). However, on closer inspection (by selecting to show wells by ‘Quarter of first flow’), you can see that there were some minor improvements since the 2nd half of 2017.

All leading operators have been unable to grow production here since early 2015, although EOG is close to its previous high (‘Top operators’ tab). Devon Energy shows the largest decline among them, with a ~60% drop.

The ‘Advanced Insights’ presentation is displayed below:


In this “Ultimate Recovery” overview the relationship between production rates, and cumulative production is revealed. Wells are grouped by the year in which production started.

For example, the 1,850 horizontal wells that started in 2011 (represented by the red curve) are now at an average rate of 15 bo/d, after having recovered 130 thousand barrels of oil and 0.8 Bcf (switch ‘Product’ to gas to see this).

Based on average cumulative production in the first 2 years, Devon Energy is still showing the best results (at 220 thousand bo/d) of the operators with at least 100 wells, while EOG is the number 5 (‘Productivity ranking’ dashboard).

Later this week I will have a post on all 10 covered US states, followed by an update on North Dakota early next week.

As you will have noticed, we have performed a major upgrade of our website. Besides this free blog, we now offer two services with which the developments in the shale oil & gas industry can be closely monitored:

  1. ShaleProfile Analytics, an online portal with similar user-friendly dashboards as shown here on the blog, but with new dashboards, and access to more up-to-date data, such as lateral positions, proppant loadings, and lateral lengths. You can request here a free trial.
  2. ShaleProfile Data, where you can subscribe to our underlying data platform, and receive monthly updates with the latest data.

You can bookmark https://shaleprofile.com/blog/ , if you wish to get quick access to the latest blog posting here.

Please tell me what you like and especially don’t like about this new setup!

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.

    Why does the Eia have the Eagle Ford producing almost 1.45 million barrels of oil per day?

    It sure looks like the Eagle Ford will be luck to produce 1.25 million barrels a day even with the updated data in about a couple of months.

    I have always thought that the EIA has be overestimating the Eagle Ford and I think they will have to continue to correct down there estimates for the Eagle Ford.

      I advice not to compare my numbers directly with the EIA, as their methodology is quite different from mine. Just a couple of differences that I am aware about:
      1. I only report horizontal wells, while the EIA reports all wells
      2. The EIA may use slightly different basin boundaries
      3. The EIA also models incomplete/missing production data, while I just report what the Texas RRC reports (which is known to be incomplete, especially for the recent 3-6 months).

  • Nick Gjergji says:

    The job present a clear picture about Eagle Ford unconventional reservoirs developed with long horizontal wells and multifracture. The services offered from Enno Peters are even more valuable on unconventional development.
    One thing is very clear on Eagle Ford unconventional reservoirs, the initial production rates are improved every year. This is related with increasing the well length, the number of fracture and the fracture solution volumes and composition plus the volume of propant. These can be seen on two services Enno Peters provide.
    On addition to these, the wells on Eagle Ford pay produce for many years, but we see that within 7-10 years the wells are stripper wells and these wells have very high cost on production if the operators will keep on production for long time.
