THESIS FRAC FLOWBACK WATER BLENDING AND TREATMENT ...

A framework for optimizing produced water ,reuse, is presented as part of this study. Typically, some volume ,of fracturing fluid, is retained in wells; further, portions of ,flowback, fluids might be injected into disposal wells. Produced water must be treated to meet recycled water quality requirements.

Hydraulic ,fracturing, is a controlled, high-pressure injection of ,fluid, and proppant into a well to generate fractures in the rock formation containing the oil or gas. After the hydraulic fracture procedure is completed, the injected ,fluid, is allowed to ,flow back, into the well, leaving the proppant in the newly created fractures.

Hydraulic ,fracturing, for natural gas extraction from shale produces waste brine known as ,flowback, that is impounded at the surface prior to ,reuse, and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compounds, and result in biocorrosion that complicates water and waste management and increases production costs.

Environmental impact of hydraulic fracturing - Wikipedia

Recycled flowback water can be reused in hydraulic fracturing. It lowers the total amount of water used and reduces the need to dispose of wastewater after use. The technique is relatively expensive, however, since the water must be treated before each reuse and it can shorten the life of some types of equipment.
