As you may know, the Marcellus Shale is considered to be the world’s second largest natural gas field. Geophysicists and geologists identify suitable well locations in areas with potential for economical gas production by using surface and subsurface geology and seismic techniques to generate maps of the subsurface. The Marcellus Shale formation is roughly 95,000 square miles and spans parts of six states (New York, Pennsylvania, Ohio, West Virginia, Maryland and Virginia).
To learn more about the formation and its geology, we encourage you to visit the Pennsylvania Department of Conservation and Natural Resources’ webpage dedicated to Marcellus and Utica Shale research in Pennsylvania.
