Experimental Study: High Viscosity Friction Reducer Fracture Fluid Rheological Advantages over the Guar Linear Gel

Abstract

During hydraulic fracture operations, fracture fluids play a critical role in carrying the proppant in fracture networks, which aims to obtain better oil productivities in unconventional reservoirs. The main objective of this work is to evaluate the rheological properties of high viscosity friction reducer (HVFR) in comparison to traditional guar linear gel fracture fluids. Two types of HVFRs (anionic and cationic) were also used for further rheological measurement analysis. The first section of the study sought to determine the effect of the fluid concentrations of both HVFRs and guar-based fluid. The second part was conducted to investigate the impact of temperature on the rheology parameters of anionic HVFRs and guar. The last section was performed to study the rheological performance of the use of anionic HVFRs in comparison to the cationic HVFR type. The results showed 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 comprehensive knowledge that can help to estimate proppant transport in unconventional reservoirs.
