This is an older blog post, you will find one on more recent data here
These interactive presentations contain the latest oil & gas production data from all 15,503 horizontal wells in North Dakota that started production from 2005 onward, through November.
North Dakota oil production was flat m-o-m in November, at 1.5 million bo/d, while natural gas production set a new record at over 3.1 Bcf/d. The horizontal rig count has stayed just over 50 during the past year. On average, each rig drilled almost 2 wells per month. In November, more than 1 million bo/d was produced from the 3.5 thousand wells that began production since 2017.
Well productivity is basically unchanged from last year, as you can find in the “Well quality” tab. Although initial production rates have steadily increased over the years, decline rates have as well. The 1,800 oil wells that began production in 2012, produced on average 220 bo/d in the first year and 110 bo/d in their second year, a 50% decline. In comparison, the 1,000 wells that came online in 2017 produced 440 bo/d and 180 bo/d in their first and second year, respectively, a 60% decline.
The drawdown of DUCs accelerated in the 4th quarter, which can be seen in the “Well status” overview, if you only select that status. Hess completed almost half of its DUC inventory in those months, which gave a significant boost in output, allowing it to take over Marathon and Whiting (see “Top operators”).
The ‘Advanced Insights’ presentation is displayed below:
This “Ultimate recovery” overview shows how all these horizontal wells are heading towards their ultimate recovery, with wells grouped by the quarter in which production started.
The general picture is a little hard to see with so many curves. But if you click in the legend on the wells that began in “2017 Q3”, you will note that it appears that well productivity has stagnated ever since.
Not only is the gas/oil ratio going up (9th tab, “Gas oil ratio”), the water/oil ratio is as well (10th tab, “Water oil ratio”). The wells that started production since 2018 are now producing 1.2 barrels of water, for each barrel of oil produced.
The following screenshot, taken from our ShaleProfile Analytics service (Professional), shows how the DUC count has evolved over the past 5 years. The DUCs are colored by the year in which they were spud.
Almost 100 of the 700 DUCs in November were spud before 2018. The location of the current DUCs can be found on the map. In our analytics service, this dashboard is fully interactive, e.g. clicking on one year will highlight those wells on the map. You can also use this dashboard to quickly figure out who owns the most DUCs and where they are.
Early next week, we will have a post on gas production in Pennsylvania.
PS. I hope you like our new website! Please comment if you have some feedback for us.
For these presentations, I used data gathered from the following sources:
- DMR of North Dakota. These presentations only show the production from horizontal wells; a small amount (about 40 kbo/d) is produced from conventional vertical wells.
The above presentations have 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.
