Between 10% and 100% of this fluid will return to the surface, and is then known as flowback fluid, becoming a waste stream. In Pennsylvania, the average amount of fracking fluid injected into production wells exceeds 10 million gallons in recent years according to data from the industry’s self-reporting registry known as FracFocus .

1/2/2014, · The total amount of flowback fluid in case of tight gas ranges from 30% up to 50%, while in case of shale gas it ranges from about 5 to 70% (King, 2012, USEPA, 2010). Injected fracturing fluid consists of water (98–99.5%) with the addition of various chemicals (polymers and biocides) and proppant (sand quartz or special granulate) ( Modern Shale, 2009 ).
