Settling of Spherical Particles in High Viscosity Friction Reducer Fracture Fluids

Investigating the key factors that impact fluid rheology and proppant static settling velocity in high viscosity friction reducers (HVFRs) is a critical aspect for successful transport hydraulic fracture treatment. In this study, rheological properties of HVFRs were tested at various temperature ranges (i.e., 25, 50, 75, 100 °C) different HVFR concentrations 1, 2, 4, 8 gpt). Three sizes spherical particle diameters 6 mm) selected to measure velocity. The was two models: an unconfined glass model confined rectangular with widths (7 10 mm). models measured using advanced video camera. results exhibited acceptable thermal stability even higher temperatures, also elasticity increased considerably increasing concentration. Increasing cut reducer efficiency suspend particles significant time, observed clearly temperatures reached 75 °C. Spherical freely settled due absence wall effect, decreased significantly as concentration increased. Additionally, angularity substantially slowed both effect several types friction. This research provides insights into parameters fracturing its transporting bounded unbounded networks.
