The pace and extent of Marcellus Shale development across Pennsylvania can be “seen” in animated maps produced by the Penn State Marcellus Center for Outreach and Research. View the animations of Marcellus Shale development across Pennsylvania.
Based on data from the Pennsylvania Department of Environmental Protection, the animations show both the number of drilling permits issued for the Marcellus Shale target and the number of wells drilled by year from 2007 through August 2010.
