Gas Drilling's Environmental Impact

Wyoming

How to read these graphs:

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 2008, Wyoming had 1,074 new wells drilled.

State Data

Wyoming’s wells drilled in 2008 and 2009 are estimates from the Wyoming Oil and Gas Conservation Commission.

BLM Data

In Wyoming, 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.
