Preparation of a Novel Fracturing Fluid System with ...

A ,fracturing fluid, was presented as a novel and useful tool for utilization in large-scale fracking. From the results collected from this study’s series of laboratory experiments, the following conclusions can be drawn: (1) The polymer, HELV, was synthesized by radical polymerization and characterized by 1 H NMR.

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.

The reduced or total absence of ,fluid, flow up the annulus when ,fluid, is pumped through the drillstring. Though the definitions of different operators vary, this reduction of flow may generally be classified as seepage (less than 20 bbl/hr [3 m3/hr]), partial lost returns (greater than 20 bbl/hr [3 m3/hr] but still some returns), and total lost returns (where no ,fluid, comes out of the annulus).

The construction time is short, at 18–24 months. In addition, because the modules and reactors are designed only once and then manufactured many times, much of the plant can be standardized and shop-fabricated in ,skid,-,mounted, modules. This reduces the cost and risk associated with building plants in remote locations.
