Leakage

The study, issued Monday by the Marcellus Shale Education & Training Center, a partnership of the Pennsylvania College of Technology and the Penn State Extension, also said that about half of the land being leased by drillers was owned by people living in those counties in 2009 — the rest was owned by people or firms based out of state or elsewhere in Pennsylvania, or owned by the state itself.

That means much of the leasing and royalty money derived from drilling goes out of the county in which the drilling takes place, according to the study.

It’s an economics phenomenon known as “leakage” — money that looks as if it is benefitting a particular area is actually going elsewhere. And it’s not an economic phenomenon native to gas drilling: Coal interests, limestone and gravel deposits and other mineral-related economic activity is subject to the same kind of leakage.
