1/7/2017, · Flowback in, fractures, (or a branching, fracture, network in shales) includes the following different stages: flowback of, fracturing fluid, (and, sometimes, suspended proppant) from the, fracture, system while, fractures, are closing on proppant (in this case the, fluid, is being ‘squeezed’ out of the system into the wellbore (Walton and McLennan, 2013)) and the filtration in a closed propped, fracture, (or partially propped, fracture, …

This is likely due to fracturing. Fractures in frozen fluid develop preferentially at the sites of microbubbles due to dissolved gas phase prior freezing. Fluid containing a larger amount of dissolved gases takes a longer time to transfer into a solid than the fluid containing a smaller amount of dissolved gases.

15/12/2018, · At the moment, it is noteworthy that viscosity of, fracturing fluid, could be recovered quickly. The, fracturing fluid, is supposed to have maximum recovery in a very short duration so as to transport the proppants into the, fracture, most effectively without any interruption. Because of high shear rates, polymer was broken and the gel became very thin.
