Polyacrylamide in hydraulic fracturing fluid causes severe

High MW polyacrylamide (PAM) was the dominant foulant in simulated slickwater hydraulic fracturing (HF) fluids. Fouling rates decreased with the size of PAM as a result of degradation during HF. Temperature and shale during simulated HF impacted fouling rate of flowback more than pressure and salinity.

Hydraulic fracturing - History, Technology, Chemicals Used

Hydraulic fracturing (hydro-fracking) . Hydraulic fracturing is the propagation of fractures in a rock layer caused by the presence of a pressurized fluid. Some hydraulic fractures form naturally, as in the case of veins or dikes, and are a means by which gas and petroleum from source rocks may migrate to reservoir rocks.
