Niobrara (CO & WY) - update through September 2018

These interactive presentations contain the latest oil & gas production data, from all 9,508 horizontal wells that started production in Colorado and Wyoming since 2009/2010, through September. Since the last post, we’ve also added several other regions in these 2 states, and they are included here.

In August a new record was set, at over 0.5 million bo/d. After revisions are in I believe September will show a higher level again. Weld County produces about 75% of this output (group production by ‘County’ to see this).

Decline rates are fairly high, and most wells are at or below 20 bo/d after 4 years on production, as you’ll see in the ‘Well quality’ tab.

In the ‘Well status’ tab the statuses are shown for all these wells. After selecting only ‘First flow’, you’ll note that the number of wells that started production in July and August (>160) was almost back to the record levels in 2014.

The final tab shows the leading operators and the location of their operated wells. Extraction Oil & Gas tripled its output in the past 1.5 years, and is now the number 3.


The ‘Advanced Insights’ presentation is displayed below:



In this “Ultimate Recovery” graph, the average cumulative production of all these horizontal wells is plotted against the production rate. Wells are grouped by the quarter in which production started.

A major jump in average well productivity can be seen near the end of 2016, marked by the pink and red curves at the top, after which it has slightly fallen.

The 2nd tab ranks all wells by their cumulative production. The best three horizontal wells since 2009 have now produced more than 0.5 million barrels of oil, and they are all located in Campbell County (WY).

Last week we published a post on gas production in Pennsylvania. Tomorrow (Tuesday), at 10:30 EST, we’ll go over that in more detail in our show at enelyst: enelyst ShaleProfile Briefings channel. If you are not an enelyst member yet, you can sign up for free at, using the code: “Shale18

We have upgraded our data release procedure, and are now able to share on a weekly basis our database with ShaleProfile Data subscribers. More info can be found here.

Later this week we will have an update on the Eagle Ford, followed by the Permian early next week.

Production data is subject to revisions.

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

  • Colorado Oil & Gas Conservation Commission
  • Wyoming Oil & Gas Conservation Commission


The above presentation has 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 selected items.
  • 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.
