Today I planned an update with more advanced analyses than I typically show. However, I still need about a week to get that right.
Instead, I’ve added a new state to my coverage area (8 now) : Wyoming! A significant portion of the Niobrara basin is located here.
The results are presented in the above interactive presentation, and here follows just a brief discussion. I’m showing all horizontal wells in Wyoming that started production since 2010.
Although smaller than Colorado, total oil production from horizontal wells still topped over 120 kbo/d early last year, after a very steep climb in just 5 years. But now activity levels have dropped significantly, and you can see the impact of that on the decline in oil production (and less so in gas). Last year about 270 horizontal wells were brought online, vs just 35 until May this year. The DUC count has not dropped significantly; you can see this in the “Well status” overview, when you select there only the “DUCs”.
It could be that I include some horizontal wells in formations that are not formally recognized as shale formations. If you happen to see that, I hope you’ll let me know.
I intend to keep Wyoming in future updates for the US as a whole, and may sometimes post an update on the Niobrara where I’ll then include production from Colorado & Wyoming.
Around Friday next week (Sep 30th), I also plan another update on the Eagle Ford.
For this presentation, I used data gathered from the following sources:
- Wyoming OGCC (with great support!)
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, and include or exclude categories.
- 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.
