US - update through May 2018

This interactive presentation contains the latest oil & gas production data through May, from 91,810 horizontal wells in 10 US states. Cumulative oil and gas production from these wells reached 8.9 Gbo and 98.6 Tcf.

Their total oil production was close to 5.5 million bo/d in May, or more than half of total US oil supply, while gas production topped 50 Bcf/d.

If you group this total oil production by ‘production level’, using the ‘Show production by’ selection, you will find that in May ~4 million bo/d came from just ~12 thousand wells that each produced over 100 bo/d. All other wells combined (~80k) produced just the remaining 1.5 million bo/d, although that also includes gas wells.

The ‘Well status’ tab shows the status of all these wells over time. Looking at the ‘First flow’ status, or wells that have just started production, reveals that since the 2nd half of 2017 between 800 and 1,000 new horizontal wells were brought into production each month (taking into account upcoming revisions), versus less than 600 in 2016.


The ‘Advanced Insights’ presentation is displayed below:



This “Ultimate recovery” overview shows the relationship between cumulative production, and production rates, over time. The oil basins are preselected, and wells are grouped by the year in which production started.

As the curves show, well productivity improved each year since 2012. The ~5.3 thousand horizontal wells that started in 2016 recovered each on average 134 thousand barrels of oil in the first 18 months, and they are on a trajectory to recover one more time that amount, before declining to level of ~20 bo/d.

Early next week I will have a new post on North Dakota.

We are still handing out free trial accounts for our ShaleProfile Analytics service, which covers more dashboards and up-to-date data. If you’re interested, you can apply for a trial here.

Production data is subject to revisions. For these presentations, I used data gathered from the sources listed below.

  • Colorado Oil & Gas Conservation Commission
  • Louisiana Department of Natural Resources. Similar as in Texas, lease/unit production is allocated over wells in order to estimate their individual production histories.
  • Montana Board of Oil and Gas
  • New Mexico Oil Conservation Commission
  • North Dakota Department of Natural Resources
  • Ohio Department of Natural Resources
  • Pennsylvania Department of Environmental Protection
  • Texas Railroad Commission. Individual well production is estimated through the allocation of lease production data over the wells in a lease, and from pending lease production data.
  • West Virginia Department of Environmental Protection
  • West Virginia Geological & Economical Survey
  • Wyoming Oil & Gas Conservation Commission


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.
