Animated Map Shows Vertical vs Horizontal Gas Wells in PA
The U.S. Energy Information Administration (EIA) has created a very cool animated map showing the transition from conventionally drilled, vertical natural gas wells to unconventional, horizontally fracked natural gas wells (Marcellus wells) from January 2005 to April 2012 (a copy of the video is embedded below). Just as cool—and startling—are a couple of bar charts (also embedded below) showing the dramatic increase in the volume of natural gas production in PA while at the same time the number of gas wells, the number of holes drilled in the ground, has gone down! How can that be?
Fracked horizontal wells drilled in shale formations are far more productive than conventional, vertically drilled wells.

On Friday the federal Environmental Protection Agency (EPA) released its results of testing for the fourth and final batch of water wells in Dimock, PA. The results are the same as the first three batches: There is and has been no contamination of the area’s water supply by chemicals from nearby hydraulic fracturing of Marcellus Shale gas wells.
