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, Indiana had 197 new wells drilled.

16 enforcement staff for 8,843 wells in 2011
2,091 class 2 underground injection wells in 2010, according to the EPA | More »

Notes: Data are for the calendar year. Wells drilled are the number of "well completions." Enforcement actions include warnings of non-compliance, notices of violation, civil penalties, administrative orders and actions by the Attorney General's Office. The 16 members of the enforcement staff include nine field inspectors and seven managers who have the authority to initiate enforcement actions. For 2010 and 2011, the budget represents actual expenditures. For 2009, 2010 and 2011, total wells are all existing wells, which Indiana defined as a well that physically exists in the field and has not been plugged and abandoned. Total wells for 2003 through 2009 came from World Oil’s annual count of total oil and gas-producing wells.
