.... The primary objective of this study is to measure the fracture fluid viscosity and elasticity of HVFR and linear guar at room temperature (21°C). Secondly, this work evaluates the proppant settling across HVFR at 3 gpt and linear guar at 20 ppt concentration, using a static model and two mesh sizes (40 and 70...

... that HVFR provided better viscosity and elasticity than linear guar even at a higher fluid concentration. Also, HVFR exhibits a higher resistance of temperature, which was clearly noticed at a temperature below 75 °C, while guar did not show any resistance of temperature even at 50 °C. This work provides...
