1/7/2017, · The fracturing fluid has a specifically designed time-dependent rheology, which is shear-thinning while the suspension is pumped down the well, then it gains a yield stress due t delayed cross-linking of the, polymer gel, right before the mixture enters the fracture through perforations, and then the fluid gets shear-thinning again after fracture closure (due to the release of encapsulated breakers …

This returned fluid is called “flowback” and requires treatment for re-use or disposal. The flowback will typically also pick up salt and harmful hydrocarbons from the formation. In 2009, it was estimated that the volume of fracturing flowback produced in Pennsylvania would increase from 9 million gallons per day to nearly 20 million gallons per day in 2011, which is a major waste management challenge.

Information from GWPC published in Modern Shale Gas Development in the United States on the composition of hydraulic ,fracturing, fluids suggests these species rarely, if ever, comprise a ,fluid, mixture used to fracture a well. Some of this mixed ,flowback, stream could contain glutaraldehyde, if used earlier in the process for well fracture.

An estimated average of 5 million gallons of fresh water per well are pumped when ,fracturing, a shale formation. Given the new regulations and increasing droughty conditions, water management has become a crucial step in well planning. Many processes are in place to treat ,flowback, water for reuse or disposal, but various obstacles have also emerged.

Best practice requires that a larger volume of water (,flowback, water) is recovered from a well after hydraulic ,fracturing, is completed, relative to the volume of injected ,fluid,. Issues and impacts Hydraulic ,fracturing, has attracted a large amount of community concern, especially in relation to potential risks to human health and the environment from the chemicals used.
