Tight gas production in Pennsylvania rose by 1% m-o-m in August, closing in on the all-time high.

But the DUC count is at a decade-low and more rigs will be needed to sustain further growth. Chesapeake is showing some excellent well results recently

These interactive presentations contain the latest gas (and a little oil) production data, from all 10,292 horizontal wells in Pennsylvania that started producing from 2010 onward, through August.

Total production

Natural gas production in Pennsylvania rose with about 1% m-o-m in August, to 20.5 Bcf/d (Hz. wells only). The main reason behind the recent growth in output is that more wells were completed than were drilled. With just over 500 DUCs, the current drilled-but-uncompleted horizontal well count is the lowest in a decade.


In the ‘Well status’ tab, you can find how this DUC count has changed over time, by selecting only the well status ‘DUC’. Below you can see the same overview, but colored by the year in which the wells were spud. The map shows the location of all these wells, using the same coloring:

EQT has with 161 the most DUCs of any operator in this area.

Supply Projection

With just 17 rigs drilling horizontal wells, a number basically unchanged in the last 1.5 years, more growth in natural gas output is unlikely in the near term in Pennsylvania:

Tight gas outlook in Pennsylvania, based on current drilling activity & well productivity

This image was taken from our Supply Projection dashboard and it shows our outlook for natural gas production in the state, based on 17 active rigs and assuming no changes in rig/well productivity.

Well performance

In the 3rd tab, the performance is shown for all horizontal wells, by vintage year of first production. It reveals that well productivity is still at an all-time high. Looking at 5 largest producers, we see that especially Chesapeake is showing strong results:

Well productivity (first 12 month cum. gas) over time, by operator. Horizontal wells only.

The 40 wells that Chesapeake completed in 2020, which already have produced for at least a year, recovered on average 6.7 Bcf of natural gas in the first 12 months. Cabot is the number 2, with just over 5 Bcf for the same metric (62 wells).

Top operators

In the final tab (“Top operators”), the output and well locations of the top 10 natural gas producers in Pennsylvania are displayed.


Next week we will have a post on the Haynesville and one on all covered US states.

Production data is subject to revisions.
