Marcellus (PA) - Gas production from unconventional horizontal wells hovered around a record level of 16 Bcf/d in Pennsylvania

Recommended Posts


Marcellus (PA) – update through April 2018

This article contains still images from interactive dashboards available on the blog post. To follow the instructions detailed here, use the interactive dashboards. You can also explore the dashboards to uncover different insights and trends.



This interactive presentation contains the latest gas (and a little oil) production data through April, from all 8,097 horizontal wells in Pennsylvania that started producing since 2010. After the significant jump in output at the end of last year, gas production has remained fairly steady at a level around 16 Bcf/d.





Similar as in other basins, operators have completed their wells since 2017 with on average 30% more proppants than in 2016, and the result can be seen in the ‘Well quality’ tab: significantly more initial production.




Chesapeake and Cabot are the leading operators in this region (see ‘Top operators’), with each above 2 Bcf/d gross operated production capacity, but Range Resources and EQT are narrowing the gap. Although their average well productivity is lower than the first two, by completing more wells they were able to grow production more rapidly.




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 producing in a certain quarter.

Also here the increased well performance in recent quarters is clearly visible. Newer wells can expect to recover 3 Bcf or more in the first 16 months on production, while this took 5 years for wells that started in 2012.




In the 4th tab (‘Productivity ranking’), Cabot is showing the best average well results in this region among the larger operators, as measured by the cumulative gas production in the first 2 years (4.7 Bcf).




Ohio still didn’t release 2018 Q1 production data. Once it does, I will have a post on this state, and include also 2017 production data for West Virginia. Next week I plan to have an update on the Eagle Ford.

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

  • Pennsylvania Department of Environmental Protection
