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, Colorado had 2,992 new wells drilled.

Notes: All data, except enforcement staff, are for the calendar year. The number of wells drilled are "well starts." Enforcement actions are defined as "Notices of Alleged Violation." Enforcement staff represents field inspectors. In addition, about 20 staff members conduct inspection-related field work as part of their responsibilities. Total wells are all active wells.

BLM Data

In Colorado, much of the oil and gas drilling takes place on land that is federally regulated, which can include national parks or Native American reservations. Data provided by the Bureau of Land Management represents wells drilled on that land.

48 enforcement staff for 7,164 wells in 2011

Notes: Data are for the fiscal year. Wells drilled and total wells include federal and Indian wells. Enforcement actions include verbal warnings and incidences of non-compliance. Enforcement staff reflects inspectors who conducted more than 10 inspections in a fiscal year and does not include National Operations Center inspectors. According to the BLM Colorado State Office, about 49 percent of its budget is dedicated to inspections. Total wells are all "usable wells."
