Boron, from an oil and gas perspective is also a big concern with regard to crosslinked gels used in hydraulic ,fracturing,. Emerging technologies can selectively extract ,boron,, he said. A participant then asked what is known about the brine in the subsurface and whether any research is being conducted on what can be done during hydraulic ,fracturing, to keep the brine in the subsurface and extract ...

What is claimed is: 1. A method for treating ,flowback, water from hydraulic ,fracturing,, comprising: selecting at least one facultative organism; introducing the selected at least one facultative organism into the ,flowback, water from hydraulic ,fracturing, to reduce sulfate reducing bacteria; and adding nitrate for increasing the redox potential of the ,flowback, water.

Identifying the geochemical fingerprints of fluids that return to the surface after high volume hydraulic ,fracturing, of unconventional oil and gas reservoirs has important applications for assessing hydrocarbon resource recovery, environmental impacts, and wastewater treatment and disposal. Here, we report for the first time, novel diagnostic elemental and isotopic signatures (B/Cl, Li/Cl ...

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." This manuscript targets turbidity along with one of the additives; borate-based cross-linkers used to adjust the...

Composition and method for treating fluids with select facultative organisms and/or nutrients. At least one facultative organism is selected and added to a ,fluid, to stimulate/facilitate biological remediation of the ,fluid,. In one embodiment, the select facultative organisms are put into frac pits/ponds containing frac water to inhibit the sulfate reducing bacteria in the frac water.

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 ...

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,.

The study recounts that at 99% TSS ,removal,, the produced water was success- fully blended into a crosslinked-gel-based frac ,fluid, suitable for hydraulic ,fracturing,. Suspended solids come in various shapes and sizes; removing the visible range of solids, the ones that contribute to turbidity, is insufficient when it comes to frac ,fluid, mixology.
