Understanding Appalachian Basin
The Appalachian Basin is a large, elongated sedimentary province extending from New York toward Alabama. Its stratigraphic record includes conventional reservoirs and multiple organic-rich shale intervals, most prominently the Devonian Marcellus and the deeper Ordovician Utica/Point Pleasant system. Production type and development intensity vary considerably across the basin’s states and formations.
For modern natural-gas reporting, EIA publishes an aggregate Appalachia series that combines major shale plays within the region. That aggregate is appropriate on this basin-level page but not on a Marcellus- or Utica-only page. State regulation, pipeline constraints and regional pricing create additional differences that a single production total cannot capture.
