This interactive presentation contains the latest oil & gas production data from all 13,253 horizontal wells in North Dakota that started production since 2005, through February 2018.
February oil production in North Dakota came in at 1,175 kbo/d, after another small month-on-month drop of ~0.5%. Completion activity in January & February was low, with just 60 and 71 new wells brought online respectively. The number of DUCs has almost stayed constant compared with a year ago (800 vs 806).
Gas production rose by double the growth rate of oil in the past year (22% vs 11%), to over 2 Bcf/d. You can see this if you switch the ‘Product’ selection to ‘Gas’.
In the ‘Well status’ overview the status of all these horizontal wells is shown over time. In February, the number of wells that were not producing (‘inactive’) rose to a new high, although it is typically at an elevated number during the winter months.
Whiting, which is the 2nd largest oil operator in the region, produced the lowest amount of oil in more than 5 years, at just over 100 thousand barrels of oil per day (see the ‘Top operators’ tab).
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.
Improvements in initial well performance are clearly visible here. Especially the wells that started in Q3 2017 had an excellent start, as shown by the light blue curve at the top, as they produced 107 thousand barrels of oil in just the first 6 calendar months.
But if the wells in the years before are an indication, it does appear that the decline after the first 1-2 years is a little steeper than before, hurting ultimate recoveries. This is for example visible if you compare only the 2010 and 2016 vintages using the ‘Year of first flow’ selection.
This may be related to the increase in gas production, which is shown when you select ‘gas’ in this overview, or view the 9th dashboard (‘Gas oil ratio’). The blue curve in the bottom graph in the latter one shows that the average gas / oil ratio in the basin has doubled in the past 7 years.
By Tuesday next week I will have a new post on the Niobrara region, followed with an update on the Eagle Ford.
If you missed my post on a projection of future oil & gas production from existing wells earlier this week, you can still find it here.
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 30 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.
