Hydraulic ,fracturing fluid, (HFF) additives are used to enhance oil and gas extraction from unconventional shale formations. Several kilometers downhole, these organic chemicals are exposed to temperatures up to 200 °C, pressures above 10 MPa, high salinities, and a pH range from 5–8. Despite this, very little is known about the fate of HFF additives under these extreme conditions.

Analysis of the fluid returned to the surface (flowback fluid) after hydraulic fracturing indicates that as little as 30 to 45% of the, guar-based polymer, pumped during the treatment returned from the well during the flowback period. 3 Polymer residues that remain in the fracture significantly contribute to lower proppant-pack permeability, leading to a loss in fracture treatment effectiveness. 1
