19/11/2014, · Zhanqing Qu et al. proposed reutilization of guar based ,fracturing fluid, in ,fracturing, process by adjusting pH value of ,flowback, fluids . The viscosities of initial and reusing system being sheared for 90 min are 200 mPa·s −1 and 85 mPa·s −1 , respectively, which are both suitable for ,fracturing,.

Fracture Cleanup Determination by Guar Measurement in ...

Measurement of guar carbohydrate from fluid flowback samples is used to estimate the amount of guar recovered after fracturing treatments. Using a field study and laboratory analysis, this paper demonstrates that the measurement of the guar polymer in fluid flowback can be used as an indication of fracture cleanup.

Hydraulic fracturing - Wikipedia

As the ,fracturing, process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the ,fracturing fluid, to deactivate the gelling agents and encourage ,flowback,. Such oxidizers react with and break down the gel, reducing the ,fluid,'s viscosity and ensuring that no proppant is pulled from the formation.
