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 ...

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

The WaterSure Standard ,fluid, system is a water crosslinking system unaffected by high TDS, ,boron, or chlorides using a conventional base guar gel with specialized crosslinker. It has three major components: a crosslinking function, a pH buffer and a basic gelling agent combined with a high TDS-tolerant surfactant and scale inhibitor.

Alum and ferric chloride were evaluated as coagulants for clarification and ,boron removal, from saline ,flowback, water obtained from a well in the Eagle Ford shale. Extremely high dosages (> 9000 mg/L or 333 mM Al and 160 mM Fe) corresponding to Al/B and Fe/B mass ratios of ∼70 and molar ratios of ∼28 and 13 respectively were necessary to remove ∼80% ,boron,.

One promising water management strategy during hydraulic ,fracturing, is treatment and reuse of ,flowback,/produced water. 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."

Addition of, magnesium chloride, in a single-stage process is a viable option for boron removal from produced and flowback water, but the chemical consumption and sludge production must be kept in mind. Conclusion. The testing conducted on boron removal proved that it can be selectively removed from flowback and produced waters.

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.
