The bar charts on the right show the actual values for each year we have data. For example, in 2011, Illinois had 503 new wells drilled.

Notes: Data are for the fiscal year. Enforcement staff is the number of inspectors and their district managers. Numbers for enforcement staff from 2003 through 2008 have been amended. The state's Department of Natural Resources informed ProPublica that the original numbers they provided were not correct, but could not account for the discrepancy. You can view the original data sent to ProPublica here. Total well count is the total producing oil and gas wells and reflect World Oil’s annual count of total oil and gas-producing wells.
