This is an older blog post, you will find one on more recent data here
With good well production data available now until June, we can have a look at how US shale has been doing in the first half of this year.
This interactive presentation covers the oil & gas production from 64764 horizontal wells in the 8 states that I currently cover (TX, ND, NM, CO, WY, MT, PA, OH), all of which have started production. Wyoming has been added since the last US update. Total production from these wells reached 5.6 Gbo, while cumulative gas production topped 46 TCF.
What have been the 5 major developments in the first half of 2016:
- About 2800 wells were brought online, compared with 6000 in the 1st half of 2015, and 6600 in H1 2014. (tooltips in the chart reveal this, when you click/tap on the chart)
- Total oil production, after peaking March 2015, is now back at levels close to 2 years earlier, in the summer of 2014.
- High activity levels in 2015 were able to hold production quite steady, but in 2016, until June, only about 60% of the legacy decline (740 kbo vs 1200 kbo) was replaced with new production. Still, this is a large number, given that completion levels were less than half compared with the year before.
- Wells, on average, increasingly deliver more of their eventual returns early on. This can be clearly seen in the “Well quality” tab, by the higher early peaks in recent years, followed by steeper declines. This higher initial productivity is an important factor behind the previous bullet point. For a somewhat fairer comparison, you can exclude the “Appalachia” and “Other” basins, which contain a high proportion of gas wells.
- The number of wells are labelled as spud, but not producing, has been reduced since early 2015 by about 25%. You can see this in the “Well status” tab, if you select the status “2. DUC”. This excludes Texas, for which I don’t have this data.
Note that in these findings I have ignored gas production. However, the presentation includes both oil & gas wells, so for a better picture, both products should be taken into account.
I introduced a way to also see the well profiles of individual wells. In the “Well quality” tab, you can now select the “Show wells by” option “Well”, to see individual wells. Make sure you do this after using the filters to narrow down your selection, to improve the performance of the presentation, and to get a sensible result.
[if you choose this selection straight away without any filtering, you’ll see after 30-60 seconds the profiles of ALL wells; very messy and slow, but an interesting finding from this is that you can see that of all these 60k+ wells, only 1 well has so far topped 1.5 million bo. This is the “USA 2D-3-1H” well in ND, and I count about 10 wells that reached 1 million cumulative bo]
Next week Thursday (October 13th), I plan another update on North Dakota.
[Update: due to a delay in the data release, I will do this update tomorrow (Friday 14th)]
Production data is subject to revisions, especially for the last few months in Texas. For this presentation, I used data gathered from the following sources:
- DMR of North Dakota
- Texas RRC. Well profiles are estimated from well status & lease production data, as individual well production data is not provided.
- Colorado Oil & Gas Conservation Commission
- Wyoming Oil & Gas Conservation Commission
- OCD of New Mexico
- BOGC of Montana
- DEP of Pennsylvania
- DNR of Ohio
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.
