The graphs on the left show the rate of growth compared to the earliest year for which we have data -- in most cases 2003. The gray lines represent a theoretical constant annual rate of change. The bar charts on the right show the actual values for each year we have data. For example, in 2011, Pennsylvania had 2,932 new wells drilled.


1,861 class 2 underground injection wells in 2010, according to the EPA | More »

Notes: Data are for the calendar year. Wells drilled, enforcement actions and total wells come from databases and reports from the state's Department of Environmental Protection. No data was provided on the number of enforcement staff for 2010 and 2011. The state's Office of Oil and Gas Management is funded by the Well Plugging Account. The budget numbers reflect this line item in the state budget. Total wells include active and inactive wells but do not include Marcellus Shale reservoirs. Pennsylvania's Class 2 injection well program is administered by the EPA and not by the state's oil and gas program.
