Hydraulic fracturing,, also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing, is a well stimulation technique involving the ,fracturing, of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking ,fluid," (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore ...

The viscosity of guar gum-based fracturing fluids is reduced at the end of a fracturing treatment to promote fluid recovery rates. To reduce the viscosity, several materials are used as gel breakers. Most of these materials cause the degradation of the polymer by hydrolysis of the acetal linkage.

Guar gum, a gelling agent, was reported to degrade under the mixed aerobic/anaerobic conditions present in an activated-sludge treatment system (34). However, recent work by Kekacs et al. (27) suggests that the high salinity of UOG wastewater can inhibit aerobic biodegradation of organic carbons, including those in guar gum and ethylene glycol.

The polymers used in ,fracturing fluid, for reservoir stimulation are mostly polysaccharides such as ,guar gum,. The ,guar, molecule is composed of polymannose backbone with galactose branching with an approximate ratio of 2:1. The solubility ,of guar gum, is greatly enhanced by the galactose branching compared to other polysaccharides.
