More than a mile beneath parts of Pennsylvania lies a mostly untapped reservoir of natural gas.

Geologists and energy companies have known for decades about the gas in the Marcellus Shale, but only recently have figured out a way to extract it from the thick black rock about 6,000 feet underground.

Now gas drillers are looking to lease local land in an attempt to find and remove the gas, whose value increases as energy prices soar.

In January 2008 leases were being signed for values near $100 per acre. By May that value had increased to over $2000 per acre.

With lease values changing so rapidly, landowners are unsure at what price to accept a lease offer.

Kenneth L. Balliet, a forestry and business management educator with the Penn State Cooperative Extension, recently took a trip to Fort Worth to see the economic impacts of those deposits. He said leases are being signed for $18,000 per acre in areas where production has proven strong.

Though there are only about 20 wells in Pennsylvania so far, Balliet expects local production to eventually rival Texas’ Barnett Shale. He said a gas company confided it plans to spend $1 billion this year in leasing agreements in Pennsylvania.

Northeastern Pennsylvania is Where the Thick Organic-Rich Shale Intervals are Located.
