1/9/2016, · Fracturing has been the one of the major contributors in increasing the flow of oil or gas from the formation to the wellbore. Polymers have played a major role in the success of the fracturing process. It has been used as, viscosity modifier, of the drilling fluid and as coating to proppant sands.

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.

Then the polymer was employed in the fracturing fluid due to its excellent elasticity using the intermolecular forces, which showed superior sand suspension capacity by dynamic sand suspension measurement. Meanwhile, a theoretical analysis was proposed as to why polymer solution has excellent suspension and drag reduction properties.

It has been used as viscosity modifier of the drilling ,fluid, and as coating to proppant sands. Coating the proppants with ,polymer, not only improves its mechanical property, but also prevents the proppant ,flowback,, reduces the generated proppant fines, and contains the loose proppant fines, which can reduce the oil or gas conductivity.

Salinity is also important, since many of the polymers work best in fresh water. Even if fresh water is pumped into the ground, the fluid that flows back (flowback fluid) may be highly saline. In that case, recycling will involve desalination, which is difficult in the presence of polymer. Solids are typically present in the flowback fluid.
