Niobrara (CO & WY) – update through October 2017

This interactive presentation contains the latest oil & gas production data from all 7,117 horizontal wells that started production in the Niobrara region (Colorado & Wyoming) since 2009/2010, through October.

The Niobrara is on a tear this year. After two years of falling oil production, the growth rate in 2017 is the highest in the history of this region. There was a small dip in September, as Anadarko shut in a large part of its production, but October set a new record again in both oil and gas output.

Initial well productivity is up significantly in 2017, as you’ll see in the “Well quality” tab.  I’ve looked in this overview at the performance of new wells (2016/2017) of the top 5 operators and found that on average EOG, Noble and Devon showed the best results.

In the “Well status” tab you can see the inflection point in 2016 of drilling activity, as operators ramped up drilling and completion activities again.

In the last tab you can clearly see the hit that Anadarko took in September, but in October it got almost back to its high in early 2015.


The ‘Advanced Insights’ presentation is displayed below:



In this “Ultimate Recovery” overview we can see even more clearly the changes in initial well performance, and what it could mean for ultimate recoveries. Wells are grouped by the quarter in which they started production (you can change this to year or month with the ‘Show wells by’ selection). Initial peak rates are up by about 50% over the past 2 years.

The 3rd tab gives an overview of the location and status of all these horizontal wells. If you select September 2017, you’ll notice the large purple blob in Weld county, representing all the shut-in wells of Anadarko during that month in connection to a deadly fire in a house in the area.

Originally I planned to show an update on Louisiana this week, but I needed a bit more time for that. It should be ready next week, after which I’ll post an update on all covered US states.

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.
