From The Pittsburgh Post-Gazette: "The Marcellus Shale is currently the 'largest shale gas play in the world,' and a study from Wood Mackenzie predicts that growth won’t stop any time soon because the formation holds more than $90 billion in remaining value." The article goes to note that "most near-term growth in the Marcellus formation will come from the liquids-rich areas of southwest Pennsylvania and West Virginia, where other valuable natural gas liquids, including ethane and propane, are found in addition to methane."
