into the environment [ibid]. Options available for treatment of residual hydraulic fracturing fluids are limited by high capital and operating costs and thus the most widely used option for the management of flowback water is deep-well injection [2]. A typical fracturing procedure in the Marcellus Shale uses 7,000 to 18,000 cubic meters

Polyacrylamide - Wikipedia
Polyacrylamide - Wikipedia

Polyacrylamide, (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
