Visualizing Marcellus (PA) oil & gas production (through April 2019)

Recommended Posts

Marcellus (PA) – update through April 2019

This article contains still images from the interactive dashboards available in the original blog post. To follow the instructions in this article, please use the interactive dashboards. Furthermore, they allow you to uncover other insights as well.


This interactive presentation contains the latest gas (and a little oil) production data, from all 8,915 horizontal wells in Pennsylvania that started producing from 2010 onward, through April.


Visit ShaleProfile blog to explore the full interactive dashboards

With March revisions in, it has become clear that another record was set, at 18.4 Bcf/d. April natural gas production was at a similar level.


New wells recover on average more than 4 Bcf of gas in the first 2 years on production (‘Well quality’ tab). It took each of the ~1,300 horizontal wells, that began production in 2013, more than 5 years to reach that level.


The top 4 natural gas producers in Pennsylvania all set new output records this year (‘Top operators’). We still list EQT and Rice Drilling as 2 separate entities.

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.

Improvements in initial well productivity have not yet stalled; the 195 wells that started production in Q4 last year had so far the best start, recovering 1.7 Bcf in the first 5 months, on average.

You can also find here that many wells from the 2010 vintage have now declined to below 500 Mcf/d, while recovering about 3.2 Bcf. The wells from the 2017/2018 vintages are on a trajectory to triple that number, on average.


Tomorrow, Tuesday July 2nd at noon (ET), we will present a 20 minute briefing on all the major tight gas basins in the US, in our ShaleProfile channel on enelyst. Registering is free: enelyst registration page.


Later this week we will have a post on the Permian, and next week on the Eagle Ford. The latest Texas data is already available in our online analytics service. For just $52 per month, you can already always access the latest production data with the Analyst version of ShaleProfile Analytics. This is a monthly subscription service that you can cancel at any time.


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

  • Pennsylvania Department of Environmental Protection
