Pennsylvania shale gas production is starting to show the effects of a partial retreat by drillers struggling with low prices and a shortage of pipelines.
The 2.25 trillion cubic feet of natural gas that companies pulled from the Marcellus and other shale formations beneath Pennsylvania during the first six months of the year was about 5.6 percent higher than the last six months of 2014, the most recent state data show. That compares to double-digit increases for every previous six-month reporting period dating to 2009.
Statewide production posted monthly drops in April, May and June, falling to nearly 360 billion cubic feet from more than 395 billion cubic feet in March. The state only required monthly reports from producers starting this year.
