EIA Video: Cumulative Natural Gas Wells Drilled in Pennsylvania

Between 2009 and 2011, Pennsylvania's natural gas production more than quadrupled due to expanded horizontal drilling combined with hydraulic fracturing. This drilling activity, which is concentrated in shale formations that cover a broad swath of the state, mirrors trends seen in the Barnett shale formation in Texas.

The animation illustrates Pennsylvania's relatively recent transition from conventional vertical wells (black diamonds) to horizontal wells (red diamonds), drilled mostly in sections of the Marcellus, Utica, and Geneseo/Burket shale formations located in the northeast and southwest portions of the state. The animation also shows that as horizontal drilling increased, the number of vertical wells [which are typically less productive] fell, resulting in an overall decline in the state's new well count.
