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 14,263 horizontal wells in North Dakota that started production since 2005, through November.
Oil production in North Dakota dropped 1% m-o-m to 1,376 kbo/d in November, after a record output in October. The main factor behind this drop appears to be the smaller number of wells that went into production in October (119) and November (108), after a busy summer (~140 completions per month).
The 2nd tab (“Well quality”) shows that the wells that came online in 2018 perform slightly better on average than the ones from the year before.
Each of the 5 largest operators produces over 100 thousand barrels of oil per day (gross) in this state (“Top operators”), and all of them increased output in 2018. Together they are responsible for over 40% of all oil produced in November.
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 year in which production started.
The graph shows clear improvements in initial well productivity over the last couple of years. Interesting is however also that wells from the 2008-2011 period decline slightly slower than those from 2012-2015. This effect remains even after correcting for refracs (which is possible in our advanced analytics service).
The gas/oil ratio (GOR) has steadily climbed in North Dakota, as is depicted by the orange curve in the bottom graph on the 9th tab (“Gas oil ratio”). The reasons behind that are revealed in the plot above it; the GOR normally climbs over the life of a well, but newer wells are also starting with a higher GOR, and see their GOR rising faster.
In the coming days we’ll have a new update on gas production in Pennsylvania, on which we will also report in our chat tomorrow morning on enelyst (10:30 am EST).
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.
