Appalachia – Landing Bench Overview

Appalachia Play Map

Horizontal Production by Landing Bench

This graphic presents all Appalachian Basin horizontals completed since 2008. Unconventional reservoirs in the Basin are predominately gas-bearing. Horizontals within the Basin are landed within the following reservoirs:

Marcellus Shale – The Marcellus Shale is a world-class source rock and reservoir, and is the leading source of natural gas production amongst North American shale gas plays. The interval has been developed in a number of states, though most prominently in Pennsylvania.

Utica / Point Pleasant – The Utica interval overlays the Point Pleasant formation, and these zones are encountered below the Marcellus in a significant area of the Appalachian Basin. The Point Pleasant generally has more favorable reservoir characteristics for shale development (e.g., higher TOC and brittleness), and development of these intervals has been heavily concentrated in Ohio.

Other – Since 2008, Appalachian Basin Horizontals completed outside of the Marcellus or Utica / Point Pleasant have been relatively limited. However, these “other” horizontal tests have commonly targeted the Huron Shale.

For additional details regarding development within these formations, please refer to the additional Play Maps included on the Appalachian Basin Overview page.
