A New Model for Matching Fracturing Fluid Flowback ...
A New Model for Matching Fracturing Fluid Flowback ...

The model accommodates formation water having a separate composition from the ,fracturing fluid,. The movements of sodium, potassium, chloride, sulfate, carbohydrate, ,boron,, etc. are modeled during shut-in and production. The compositions of the produced water calculated by the simulator were compared to field production samples.

Treatment Of Flowback For Reuse: An Emerging Oilfield ...

Water recycling is a growing practice in North American hydraulic ,fracturing, operations. While freshwater remains the predominant ,fracturing fluid, across the industry, an increasing number of operators are completing wells with blends of freshwater and brine water that flows back from completed and producing wells (,flowback,).

Laboratory Study on Boron Removal Technology for Reuse of ...

Boron in fracturing flowback, liquid could not only influence the reuse of guar gum ,fracturing fluid, but also pollute environment. The ,boron, in the ,fracturing flowback, liquid which was pretreated through coacervation,chemical precipitation and filtration was removed using selective resin. The experimental results show that: when the ,fracturing flowback, liquid with the pH of 8. 0 and the solid ...

simulated water and ,fracturing flow back fluid, after treatment were added ,boron, content of 10mg/L and 18mg/L respectively, the viscosity of the base ,fluid, to meet the requirements, however, ... Tap water and ,fracturing flowback fluid, after treatment to the sampling for partial ion measurement and No.2 simulated water ions in Table 1. Table 1.

BORON REMOVAL FROM HYDRAULIC FRACTURING …

wastewater generated by hydraulic ,fracturing, is on-site treatment and reuse. In particular, the saline ,flowback, water contains many of the chemicals employed for fracking, which need to be removed before possible reuse as “frac water.” This manuscript targets one chemical of …

Testing for Potential Contaminants Associated with ...

This is called ,flowback, water. The amount of ,flowback, varies, and it can be as little as 10% or essentially most of the water. Typically, 20 - 40% of the water returns to the surface. Initially, this water will primarily contain contaminants found in the ,fracturing fluid,.

In order to treat the ,boron, crosslinker remained in the back flow of guar ,fracturing fluid, so as to recycle the back flow, the complexation of polyalcohol and α-hydroxyl carboxylate on boric acid was investigated, and three efficient ligands were screened out, including mannitol, xylitol and sodium gluconate. Then, their masking effects on residual ,boron, crosslinker were experimentally compared.

Another common incompatibility is caused when ,boron, is higher than 12 ppm, which increases the likelihood of overly cross-linking ,fracturing fluid, and results in substandard ,fluid, stability. Specially formulated bipolymer cross-linked fluids can achieve economic produced and ,flowback, water reclamation, and are not affected by variable water quality.
