Is PA Sitting on the Largest Natural Gas Reserves in the World?

Interesting comments about the scope of natural gas reserves in both the Marcellus and Utica Shales under Pennsylvania, from a state DEP official:

Pennsylvania might be sitting on the largest gas reserves in the world, a Pennsylvania Department of Environmental Protection official said in Laporte on Friday.

The Marcellus Shale is the second largest natural gas reserve in the world, said Scott Perry, the director of the Pennsylvania Department of Environmental Protection’s Bureau of Oil and Gas Management. And underneath the Marcellus Shale lies another source of natural gas, the Utica Shale, "which is potentially as productive at the Marcellus Shale, maybe even more so," Perry said.

Together with other existing underground reserves of natural gas in the Commonwealth, "Pennsylvania might be sitting on the largest gas reserves in the world," Perry said at a meeting of Sullivan County Energy Task Force in Laporte.*
