Marcellus waste up by half in SWPA this year

fIt’s no surprise that with a more than 50 percent jump in gas production in southwestern Pennsylvania there is a corresponding spike in flowback water generated from fracking during the first six months of this year, compared with the second half of 2010.

Here’s how the newly-released waste numbers break down for this region.

1.8 million barrels of fracturing fluid, of which 1.1 million is being reused.

For example, EXCO Resources is responsible for a small percentage of fracturing fluid either being injected into an underground well or being taken to the Reynoldsville Sewage Authority, a municipal sewage plant.

2.7 million barrels of brine, of which about 10 percent was injected into disposal wells in Ohio and West Virginia.Read More
