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.

16/4/2020, · By comparison, for conventional wide-biwing fractures the carrier fluid must be sufficiently viscous (normally, 50 to 1000 cp, at nominal shear rates from 40-100sec -1) to transport higher proppant concentrations (1-10 PPA per gallon). These treatments are often pumped at lower pump rates and may create wider fractures (normally 0.2 to 1.0 in.).
