文摘
- •
VES fluids are tested for a flow-regulated viscosifier- and breaker-free system.
- •
The fluid is Newtonian at low flowrates and viscoelastic at high flowrates.
- •
Proppant is suspended in the viscoelastic regime above a critical flowrate.
- •
Viscoelastic behavior disappears upon the secession of high shear rates.
- •
The fluid is low viscosity and Newtonian during flow through a proppant pack.
