Why Marcellus Shale?
Marcellus Shale, which extends through Pennsylvania, New York, Ohio and West Virginia, is touted to become one of the biggest gas fields in the U.S. In 2002, the United States Geological Survey said the Marcellus Shale contained an estimated undiscovered resource of about 1.9 trillion cubic feet of gas. In early 2008, Terry Englander, a geoscience professor at Pennsylvania State University, and Gary Lash, a geology professor at the State University of New York at Fredonia, said the Marcellus Shale might contain more than 500 trillion cubic feet ( TFC ) of natural gas, of which 50 TFC would be recoverable by advanced drilling techniques. The United States produces about 30 TFC of natural gas each year and if these estimates prove correct, the Marcellus Shale could more than suffice the US natural gas demand and could be one of the biggest natural gas fields in the U.S. Other biggest gas fields in the U.S. include Barnett Shale in Texas, Fayetteville Shale in Arkansas and the Haynesville
