Can Produced Or Flowback Water Be Reused As Fracturing Fluid?
Can Produced Or Flowback Water Be Reused As Fracturing Fluid?

Once suspended solids and bacteria were addressed, what remained was to test chemical methods of negating the effect of interfering ions, salinity, boron, calcium and chlorides. Two new robust fracturing fluid systems were developed and tested that, when added to the water, result in a clean, low-residue stimulation fluid.

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.
