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.

To free the gas, a mixture of water, sand, and chemicals is injected deep underground into wells vertically and then horizontally at extremely high pressure. The pressurized ,fluid, mixture fractures the rock and allows the natural gas to rise to the surface through the recovered water—called ,flowback, water (FBW).

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.

Before putting the well on ,flowback,, the induced fractures are occupied by the compressed ,fracturing fluid,. Therefore, analyzing the produced ,fracturing fluid, should in principle be able to characterize the induced fractures, and complement the production data analysis. We develop a rate transient model for describing the ,fracturing fluid flowback,.
