Eagle Ford - update through November 2017
03 / 15 / 2018
This interactive presentation contains the latest oil & gas production data from 19,876 horizontal wells in the Eagle Ford region (TRRC districts 1-4), that started producing since 2010, through November 2017.
Unlike the Permian in the west of Texas, the Eagle Ford has not shown much growth in oil production in 2017. Although the above graph shows November at a lower level than at the start of the year, I expect that once revisions are in, it will be roughly equal.
An important reason for this difference is that well productivity here hasn’t increased significantly in the past 3 years, as can be seen in the ‘Well quality’ tab (which you can compare with my last last post on the Permian).
Of the leading operators, EOG has kept production rather steady since early 2015, while Devon is down by 75% in the same period, mostly due to natural decline (see the ‘Top operators’ overview).
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 quarter in which production started.
Also here, despite somewhat higher initial performance, the lack of clearly better longer term results in oil recovery for newer wells is visible. Natural gas production is better though, as you will see if you switch ‘Product’ to gas.
In the 2nd tab (‘Cumulative production ranking’) you can find all counties in the Eagle Ford region, ranked by the cumulative gas production from horizontal wells since 2010. It shows that Webb is by far the most prolific county, with more than double the gas production compared with the number 2 (DeWitt county).
Next week I plan to have a post on all 10 covered states in the US, and another on the latest production numbers from North Dakota.

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.
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.
