Because drilling rigs move around and operators often drill multiple wells from each wellpad, this count is a more accurate representation of the number of locations around the Commonwealth where land has been cleared, pipelines have been laid, impoundments have been built, water and chemicals have been trucked in, and equipment has been assembled to drill and frack one or more wells.
Click here or the animation above to explore an interactive map of wellpads observed in 2005, 2008, 2010, and 2013. The animation shows all observed wellpads cumulatively, 2005 = Blue, 2008 = Yellow, 2010 = Orange, and 2013 = Red.
By itself this data might not be much different than what you could generate from looking at permit data and when drilling began, but we have included this phase in all our FrackFinder projects so that we can be sure we are looking at all the right places. Sometimes permit data is backlogged and a dataset you download today may not reflect everything that is happening in the real world. Additionally, having several years of crowdsourced image analysis data will enable us to do some nice comparisons to see how accurate state data are, as well as check the accuracy of our citizen scientists.

To provide some context for all those points on the map, check out these aerial photos from our parters at the Downstream Project. Wellpads are typically 3-5 acre gravel parking lots surrounded by roads, impoundments, pipelines, and other related infrastructure. In high-density drilling areas, or areas with a lot of steep terrain, these sites can occupy 15-20 acres of interconnected industrial activity. Ultimately, we are doing these studies so that we can better understand the public and environmental health implications of living near these operations.
Stay tuned for news about a new FrackFinder project coming up for a brand new state (Hint: It's a very mountainous state and the only one in the Union with this cardinal direction of the compass in its name).
