Marcellus (PA) & Utica (OH) - update through June 2017

This interactive presentation contains the latest gas (and a little oil) production data from all 9105 horizontal wells in Pennsylvania and Ohio since 2010, through June. Data for West Virginia is also included, but deselected in most views, as it contains only data through Dec 2016 (use the “Basin” selection to include this state).

During each of the previous 2 years, gas production did not grow by much during the 2nd quarter, and 2017 was no exception. Still, gas production from horizontal wells was near an all-time high of close to 19 Bcf/d in June, and I expect to see it rise further in the 2nd half.

In the “Well quality” tab you’ll see that new gas wells peak at a rate of close to 10 MMcf/d in 2017, while the wells that started in 2010 are now at a production rate ~500 Mcf/d. Longer laterals, and heavier fracs, have also had a significant effect on the wells in this basin.

Since the 2nd half of 2016, drilling activity has increased in this area, resulting in a larger drilled, but uncompleted, well inventory (see the “Well status” tab).

As the “Top operators” tab shows, all leading operators are close to, or at their highest production levels in history.

The ‘Advanced Insights’ presentation is displayed below:

 

 

This “Ultimate Return” overview shows the relationship between gas production rates, and cumulative gas production, averaged for all horizontal wells that started production in a certain year.

Although Chesapeake is by far the largest producer in this area, you can see (after selecting only this operator in the “Operator” selection) that until recently its best wells started production in 2010/2011. Wells that started since the 2nd half of 2016 appear to finally beat the performance of those earlier wells.

Next week I will have new posts on the Eagle Ford and the Permian.

I’ve made again a major update to the Get the Data page. Now the “US Unlimited” data package is available. This does not only include detailed well data for 80k+ horizontal wells, but also lease and lease production data for Texas and Louisiana, and several other types of data. The idea behind this dataset is to provide detailed insight into the results of the lease allocation algorithm, which is necessary in these 2 states (production is provided by lease, not well).

A new sample dataset is available there as well, which can be freely downloaded. It addresses several issues found in the previous one.

Production data is subject to revisions. For this presentation, I used data gathered from the following sources:

  • Ohio Department of Natural Resources
  • Pennsylvania Department of Environmental Protection
  • West Virginia Department of Environmental Protection
  • West Virginia Geological & Economical Survey
  • FracFocus.org

 

====BRIEF MANUAL====

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.
