BORON REMOVAL FROM HYDRAULIC FRACTURING …

fracturing wastewater is only beginning to be investigated. Importantly, boron removal specifically has not yet been established [7]. Boron adsorption onto iron and aluminum hydroxides has been reported to be endothermic [27, 28] and shown to decrease with increasing concentrations of anions such as carbonate, phosphate, and arsenate [28]. We

in most cases, from produced waters sampled from conventional ,oil, and gas wells. In addition, it has been proposed that ,boron, isotope geochemistry can be used to quantify small fractions (~0.1%) of ,flowback, water in contaminated fresh water This is likely to be universally applied to trace ,flowback, waters in other shale basins.

9/10/2014, · However, about twice as much water is used per unit of energy (water-to-,oil, ratio, WOR, vol water/vol ,oil,) in the ,oil, zone (WOR: 1.4) as in the gas zone (water-to-,oil,-equivalent-ratio, WOER: 0.6). We also found large differences in water use for ,oil, between the two plays, with mean Bakken water use/well (2.0 × 10 6 gal/well) about half that in the Eagle Ford, and a third per energy unit.

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.

Guar gum ,fracturing flowback fluid, has become one of the main pollution sources to oilfield water. If the ,flowback fluid, is used to re-mix ,fracturing fluid, after treatment, it not only protects the environment from being polluted, but also saves water resource and reduces operation cost. To simplify the treatment process and to increase the volume of treatment, a method for the ,removal, of ...

Whereas a conventional HF may unload from 200 to 500 bbl of water per well, an unconventional HF may unload from 10,000 to 50,000 bbl of water per well. Conventional HF ,flowback, typically contains emulsified ,oil,, and often contains other stimulation fluids, such as aromatic solvent and/or spent acid.

The ,fluid, opens the rock and carries the proppant. This keeps the fractures open, enabling the rock to release any ,oil, or gas trapped inside and flow to the wellbore. Typically, the ,fracturing fluid, is comprised of about 98 percent to 99.5 percent water, with the proppant and chemicals making up the remaining 0.5 percent to 2 percent. 1

A recent innovative development in the ,removal, of organic species from ,flowback, waters is the potential to use an advanced oxidation process in a batch-wise treatment mode. One unit supplied by Ozonix uses a combination of injection of in-situ generated ozone, hydrodynamic and acoustic cavitation plus electrochemical oxidation to produce the very reactive hydroxyl radicals in the reaction chamber.

Using ,boron, and lithium tracers, scientists can determine if fracking ,fluid, contamination has been released into the environment, which will help identify ways to improve disposal and treatment of shale gas wastewater. Hydraulic ,fracturing, fluids typically contain mixes of water, proprietary chemicals and sand. Mixtures can vary from site to site.

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.
