Synthetic ,flowback, water was obtained by reacting the synthetic ,fracturing fluid, with 25 g/L shale at 80 ℃ and 83 bar for 24 h simulating downhole conditions encountered in natural gas reservoirs. The variation in these conditions across different gas formations can be large,and its impact on polyacrylamide degradation was investigated previously.

1 Introduction. Among the many well stimulation methods having been developed for increasing oil and gas production, ,hydraulic fracturing, (HF or fracking) did not seem extremely special when first attempted in the late 1940s ().Early treatments injected approximately 4–40 m 3 of ,fluid, under high pressure into the well. The high pressure was necessary at the well bottom, where the ,fluid, ...

After the shale rock is cracked, the liquid is pumped back to the surface to retrieve the natural gas, this ,process, is known as ,flowback, (Allen et al. 2013). After natural gas is retrieved, the fracking liquid is either pumped back into a separate well and then the well is closed; transported to a water ,treatment, facility or re-used for the stimulation of another well.

The advantages of this fracture fluid are: large reservoir volumes stimulated, better fracture containment and damage reduction generated by gels. Its disadvantages are: excessive use of water, narrower fracture widths that other fluids and a poor capacity to carry the proppant toward the interior of the fracture due to its low viscosity.
