completed, fracturing fluid flows back to the surface along with gas and oil. The flowback and produced waters are collectively called “HF water”. This flowback fluid and water that remains underground is a great threat to the environment and is estimated that only 5-60% of the fracturing fluid flows

T he number of hydraulic ,fracturing, (fracking) shale oil and gas wells in the US and worldwide continues to increase. However, as more come into operation, so does the stress on surface water and groundwater supplies. Up to 3,785m 3 of fresh water per wellhead is required to carry out the fracking process alone. Equally important is the growing volume of wastewater generated from fracking ...

The case for designing a ,bactericide, program to match, and not exceed, the required amount of bacterial control is clear, but rarely is the bacterial load determined during and after the job to verify this balance. Herein, we report a case study undertaken to evaluate the bacterial load of field mix water and ,flowback, water during and after a large hydraulic ,fracturing, job in the Marcellus Shale.

21/3/2013, · Breakers are added to the ,fracturing fluid, to reduce the molecular weight of the various polymers used. This reduces the viscosity and facilitates the blowback of residual polymer which allows for cleanup of the proppant pack. The inappropriate use or ineffective breakers can cause significant damage in the proppant pack and a reduced PI.

Proppant suspended in a viscosified fracturing fluid is then carried out and away from the wellbore within the fractures (as the fractures are created) and extended with continued pumping. Ideally, upon release of pumping pressure, the proppant materials remain in the fractures, holding the separated rock faces in an open position forming a channel for flow of formation fluids back to the wellbore.
