Home » Marcellus Shale Marcellus Shale: News, Videos, Maps, Lease and Royalty Information Marcellus Shale Formation Marcellus Shale Orientation: The Marcellus Shale, is a black shale of Middle Devonian age that underlies much of Pennsylvania, New York, Ohio, West Virginia and adjacent states. Geologists have long known that the Marcellus contains natural gas, however, the depth of the rock unit and its low permeability made the Marcellus an unconventional exploration target. Within the past few years two technologies, hydrofracing and horizontal drilling, have been tested in the Marcellus resulting in some of the most productive wells in the eastern United States. These developments triggered an explosion of drilling and leasing activity in the areas above this rock unit. The potential of the Marcellus is significant. It is thought to contain about 50 trillion cubic feet of natural gas - enough to supply the entire United States for two years with a wellhead value of one trillion dollars. The Marcellus is also the closest natural gas to the high demand markets of New York, New Jersey and New England. The purpose of this webpage is to aggregate information about the Marcellus Shale and provide a convenient resource for scientists, companies and citizens.
