Niobrara (CO & WY) - update through November 2016
03 / 16 / 2017
This interactive presentation contains the latest oil & gas production data from 5864 selected horizontal wells in the Niobrara region (Colorado & Wyoming) through November.
Most of the oil in this region is produced in the DJ (Denver-Julesberg) basin, but a significant portion is also coming from the Powder River basin, which overlaps with Northeast Wyoming.
Oil production from this area basically doubled in 2014, and since the 2nd quarter 2016, it was again at a level seen near the end of 2014, of around 350k bo/d. Just over half the number of horizontal wells started production in 2016, compared with the same period in 2015 (741 vs 1305).
Total gas production continued to grow in 2016, although the pace was lower compared with the very steep rise in 2014.
Moving to the 3rd tab (“Well quality”), you’ll notice that despite the steep drop in newly producing wells, well productivity hasn’t changed much since 2014. Wells have become more gassier on average, which can be seen if you switch to gas using the “Product” selection.
In the top graph of “Well status” tab we can see the status of all these wells over time. You may notice that there was an uptick in drilling again in November, as 125 wells were spud. Will this mark the start of a period with rising oil production again?
Declines are rather steep here, and as the bottom graph shows, almost 70% of all these wells, that started production since 2010, were in November at a level below 50 bo/d.
Anadarko and Noble Energy are the largest producers in these 2 states, as the last tab shows. Both have most of their production in Weld county (CO), and both slowed down a little compared with their production tops in 2015.
The new ‘Advanced Insights’ presentation is displayed below:
This “Ultimate recovery” overview shows how all these horizontal wells progress towards their ultimate recovery, while declining over time. The wells are grouped by the year in which they started production (“first flow”).
The 2nd tab ranks all these wells according to cumulative production. Three wells have breached the 400 kbo cumulative production level, while the median well is so far just below 70 kbo.
In the “Well status map” overview we can easily see where all these wells are located. If you select only “First flow” in the “Show well statuses” selection, you can see where new wells started production in November: almost all in, or around, Well county (CO).
Around next week Tuesday I plan another update on Pennsylvania, followed by a post 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.
