Abstract

Hydraulic fracturing treatments may significantly improve the oil production from wells in unconventional reservoirs by enhancing the fracture conductivities. Fracture conductivity can be improved by efficiently transporting and distributing the proppant through the lengths of the fractures. The main target of this study is to evaluate the viscosity and elasticity of high viscosity friction reducer (HVFR) for the purpose of transport and suspend the proppant at a temperature of 25°C. This study an alyzes the settling of proppant across HVFR using two different concentrations, 0.5 and 1 gallon per thousand of gallon (gpt). The tests were conducted using two static models and three different spherical particle sizes (2,4, and 6 mm). Also, the settling of the proppant was performed using proppant size of 40/70 mesh size. The study also assessing the distribution of proppant using a dynamic model. Proppant transport evaluations inside the dynamic model were performed utilizing various concentrations of HVFR and a sand mesh size of 40/70. The findings demonstrated that the viscosity and elasticity of HVFR improved as the concentration increased from 0.5 to 1 gpt. Furthermore, the findings indicated that HVFR at a concentration of 1 gpt is capable of suspending the proppant for a significant time, when compared to the HVFR at a concentration of 0.5 gpt. The work exhibits the settling velocity of the proppant utilizing low HVFR concentrations and examines how the rheology may impact the proppant transport.
