Marcellus (PA) – update through March 2019
05 / 28 / 2019
This interactive presentation contains the latest gas (and a little oil) production data, from all 8,853 horizontal wells in Pennsylvania that started producing since 2010, through March 2019.
Gas production in Pennsylvania dropped by a small amount in March, but remained close to January’s record output, at 18.2 Bcf/d. In the first quarter of this year, 147 wells started production, almost unchanged from a year earlier (142).
New wells peak at a level of around 12,000 Mcf/d, which is roughly 20% higher than the peak rate of wells that came online in 2017 (‘Well quality’ tab).
Range Resources was the only operator in the top 5 that increased production in March and it is now just above 2 Bcf/d of operated production (final tab).
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 began production in a certain quarter.
If you go through these quarters (click on a quarter in the legend to highlight the respective curve), you’ll note that initial well productivity has steadily improved over the years. The 195 horizontal wells that started in the final quarter last year had again the best start and recovered 1.4 Bcf of natural gas in the first 4 months on production, on average. If they follow a similar decline path as earlier wells, they will recover around 10 Bcf of gas each, before they’ve fallen to an average production rate of 500 Mcf/d.
In our subscription service you can easily find that these new wells are completed with nearly 18 million pounds of proppants, on average. This is double the amount that was used just 4 years ago.
While output in Susquehanna, the most prolific county, is still rising rapidly, other counties appear to be over their peak. See for example the production in Lycoming and Wyoming in the screenshot below. It reveals the total gas production in the top 6 counties in Pennsylvania. The map on the right shows the exact location of the horizontal wells in these counties.

Next week, we will have new posts on the Permian and the Eagle Ford. Texas recently released production data through February/March, which is now already available in our analytics and data services.
Production data is subject to revisions. For this presentation, I used data gathered from the following sources:
- Pennsylvania Department of Environmental Protection
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.
