Pennsylvania’s Drake Well is known for sparking the first oil boom in the United States in 1859. In more recent history, the industry has resurrected hydrocarbon extraction in the Commonwealth through unconventional oil and gas drilling – or fracking. Between 2002 and October 28, 2015, at least 16,826 of these high-impact wells have been approved statewide, and 9,508 drilled.
While standard maps can be useful to show the reach of the industry in aggregate, they aren’t the best way to show how drilling activity has changed over time. Luckily, we have other tools in the toolbox to show the trend. See drilling by year in this time sequence map below.

This representation starts slowly, just as the industry did in the state. Activity begins to pick up around 2008. In later years, watch exploration expand throughout the Marcellus and Utica shale plays. Eventually the activity concentrates in the northeastern and southwestern portions in the state.
