"Between 2009 and 2011, Pennsylvania's natural gas production more than
quadrupled due to expanded horizontal drilling combined with hydraulic
fracturing (see chart below). 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 above 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
Historically, natural gas exploration and development activity in
Pennsylvania was relatively steady, with operators drilling a few
thousand conventional (vertical) wells annually. Prior to 2009, these
wells produced about 400 to 500 million cubic feet per day of natural
gas. With the shift to and increase in horizontal wells, however,
Pennsylvania's natural gas production more than quadrupled since 2009,
averaging nearly 3.5 billion cubic feet per day in 2011 (see chart above)."
MP: The chart below shows the monthly number of "shovel-ready" energy-related jobs in Pennsylvania, which have almost doubled from 20,000 in early 2006 to almost 40,000 this year in April. With each new shale gas well comes more than 100 new "shovel-ready" jobs as the graph clearly illustrates. Drill, drill, drill = jobs, jobs, jobs.
