This means that using the low-density proppant (small ρ p) and low-viscosity fracturing-fluid (small μ w) in hydraulic fracturing treatment, assists in recovering the fluid and inhibiting the proppant flowback.

Flowback Fluid, Handling. After the hydraulic ,fracturing, process is complete for each zone, fracture fluids ,flow back, up the well under formation pressure. These ,flowback, fluids may represent as little as 3% or as much as 80% of the fracture fluids initially injected into the well. Traditionally, ,flowback, fluids have been stored in lined pits.

Fracturing, fluids – a mix of water and sand plus several additives – is then injected at high pressure into the formation to create fissures (a narrow opening or crack). When the pumping of the fluids is stopped, the internal pressure of the geologic formation causes most of the injected fluids to rise to the surface; this ,fluid, is called ,flowback, .

There are two types of fracking wastewater: ,flowback, and produced. ,Flowback, water refers to the ,fluid, that returns to the surface upon completion of a ,hydraulic fracturing, event prior to production. Produced water refers to the ,fluid, that returns to the surface once the well starts producing natural gas and oil.

The vacuum multi-effect membrane distillation system as a more effective treatment system has been proposed for treatment of flowback. However, the quantity of waste water needing treatment and the improper configuration of sewage plants have become an issue in some regions of the United States.

A single well hydrofracture in the Marcellus may require two million to five million gallons ,of fracturing fluid,, of which an average of 25 percent may be returned to the surface as ",flowback," or "produced water." Historically, ,flowback, and produced water has traditionally gone to metals-precipitation plants, where metals and items are removed.

Mechanism. Hydraulic ,fracturing, is the process of pumping ,fluid, into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.
