These interactive presentations contain the latest oil & gas production data from all 24,208 horizontal wells in the Eagle Ford region, that have started producing from 2008 onward, through November 2019.

Oil production came in again at just over 1.3 million bo/d (after upcoming revisions), as it has since the start of 2019.

Well results have not improved since 2017, as is clearly visible in the bottom chart of the “Well quality” tab. In the core of the oil window, in Karnes and DeWitt, well productivity has slightly declined (select these counties using the “County” filter). This is without taking into account the fact that laterals have gotten longer and proppant intensity has gone up.

In the “Well status” tab the status of all these wells can be found. The bottom chart shows the % of wells by production rate. In November, about 60% of the wells in this basin produced below 25 bo/d. After removing the gas wells (a subscription only feature), this percentage drops to 55%.

EOG’s production fell below the 250 thousand bo/d, a level it first reached 5 years earlier (“Top operators”). Its December production (available in our subscription services) increased again. Meanwhile, Chesapeake set a new production record in November.

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.

In this screenshot, taken from ShaleProfile Analytics, you can see all the horizontal wells in Karnes and DeWitt County, colored by the Gas/Oil ratio in the most recent month. The charts on the right show the production rate and gas/oil ratio versus cumulative oil production, by vintage:

These charts reveal that the wells that came online in 2018 became gassier faster than the wells from the year before (bottom chart), while the decline rate has increased (top chart).

Early next week, we will have a new post on all covered states in the US.

Production and completion 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.
• FracFocus.org
