As the ,fracturing, process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the ,fracturing fluid, to deactivate the gelling agents and encourage ,flowback,. Such oxidizers react with and break down the gel, reducing the ,fluid,'s viscosity and ensuring that no proppant is pulled from the formation.

Flowback from the development of shale gas contains fracturing fluid additives as well as suspended and dissolved constituents from the shale formation including high concentrations of salts and metals (Gregory et al., 2011; Barbot et al., 2013), dissolved and nonaqueous hydrocarbons, and in some locations naturally occurring radioactive material (NORM; Hill et al., 2004; Soeder & Kappel, 2009).

Flowback resurfaces after frac fluid (an abbreviation of fracturing fluid) is injected into an oil or natural gas well to reduce friction pressure and create a fracture. Operators either recycle flowback for reuse in another oil or gas well or dispose of it at an underground injection facility.

direction of ,fluid, flow is reversed, allowing ,fracturing fluid, and naturally occurring substances to flow out of the well bore to the surface. This mixture of fluids is called ,flowback,. •The hydraulic ,fracturing, process mobilizes salts, metals, and radioisotopes from the subsurface and returns hypersaline ,flowback, water to the surface.

Flowback water, (aka backflow water) is the murky, salty water from fracing natural gas wells. It consists of frac ,fluid, which returns to the surface (aka the frac load recovery) as well as produced water.This water contains clay, dirt, metals, chemicals and even diesel that may have been added. The frac load recovery can be anywhere from 15-40% percent of the volume of ,fluid, that is injected ...

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.

Chemicals in Hydraulic Fracturing

Large volumes of water are injected under pressure to fracture the formation and to release entrapped gas bubbles. The gas is subsequently collected at the surface together with the ,flowback, (the reemerging ,fracturing fluid,) and formation water (the emerging geogenic ,fluid,). For process optimization multiple chemical additives are employed.
