Natural gas production in Pennsylvania was 20.2 Bcf/d in November (Hz. wells only), 1 Bcf/d below the output 12 months earlier.

These interactive presentations contain the latest gas (and a little oil) production data, from all 10,584 horizontal wells in Pennsylvania that started producing from 2010 onward, through March.

Total production

Natural gas production in Pennsylvania was 20.2 Bcf/d in November (Hz. wells only), 1 Bcf/d below the output 12 months earlier. After 10 years of rapid production growth, natural gas production has stagnated since early 2021. In this post, we’ll analyze some of the factors behind this.

Drilling Activity

As of last week, 22 rigs were drilling horizontal wells in Pennsylvania (according to Baker Hughes). Eleven years earlier there were over a 100 rigs, despite natural gas prices at relatively high levels in the past year:

Horizontal rig count in Pennsylvania (left hand side) and natural gas prices (right hand side)

In this overview, you can see how the horizontal rig count (in blue) has fallen since 2011, with an uptick in activity at the beginning of 2022. Natural gas prices (HH) have fallen recently, after surging a year ago.

Well productivity

In the following overview, you can find another reason behind the stagnation of hydrocarbon production in Pennsylvania:

Well productivity over time (top chart) and completion designs (bottom 2 charts) in Pennsylvania

In the top chart, you can see how well productivity, as measured by the average cumulative gas recovered in the first 6 months has trended over time. The horizontal wells that came online in 2011 recovered about 0.5 Bcf of natural gas during the first 6 months, while those beginning in Q2 of 2021 did about 5 times that (2.6 Bcf). However, the trend in the last 2.5 years does appear to be falling, despite long lateral lengths (2nd chart) and high proppant loadings (bottom chart). The 148 horizontal wells that were completed in Q2 of last year were frac’ed with 23 million pounds each, compared with an average of 4 million pounds for wells completed in 2022.

Operator performance

However, not all operators are equally affected by declining productivity. In the next graph you’ll find how well productivity of the top 5 operators has changed over the last decade:

Well productivity of the top 5 natural gas producers in Pennsylvania


In the figure above you can find the performance of the top 5 operators in the past decade, as measured by the same metric (average cumulative gas recovered in the first 6 months). Especially Chesapeake has seen a rapid decline in average output in the past 2 years, although it is still just in the lead, above EQT, which has seen almost continuous increases in productivity.

Top operators

In the final tab (“Top operators”), the output and well locations of the top-10 natural gas producers in Pennsylvania are displayed. You’ll find here that EQT’s overall production has still fallen, despite the growing productivity as we just saw, as it completed far fewer wells; 33 through November 2022, vs 129 in the first 11 months of 2020.
