Zero Flowback Rate of Hydraulic Fracturing Fluid in Shale ...
Zero Flowback Rate of Hydraulic Fracturing Fluid in Shale ...

ZFR of HFF is a concept compared with the ,flowback, rate of the ,fracturing fluid, for a conventional reservoir. It is worth noting that zero in the ZFR concept does not stand for the absolute number 0. It means that reducing the ,flowback, rate of HFF is the goal of the ZFR strategy.

16/4/2020, · The viscosity of the ,fracturing fluid, is an important point of differentiation in both the execution and in the expected fracture geometry. Many current practices, generally referred to as "slickwater" treatments, use low-viscosity fluids pumped at high rates to generate narrow, complex fractures with low-concentrations of propping agent (0.2-5 lbm proppant added (PPA) per gallon).

Hydraulic ,fracturing, is a stimulation technique used to increase oil and gas production from underground rock formations. Hydraulic ,fracturing, involves the injection of fluids under pressures great enough to fracture the oil- and gas-producing formations. The ,fluid, generally consists of water, chemicals, and proppant (commonly sand).

Polymers in the flowback fluid can be in different states of solution and have significantly different molecular weights from the polymers that were pumped downhole. In many cases, a breaking agent is used to reduce polymer viscosity, which promotes HF fluid flow from the fracture and helps the proppant stay in place during flowback.
