... of Najmi (2015) indicate that higher critical velocities are required with increasing the liquid viscosity, particle size and particle concentration. However, the predictions of the models of Salama (1998) , Stevenson et al. (2001) and Danielson (2007) demonstrate that these models do not take...

... Abstract The goal of this work was to examine the effect of sand sampling location and method on the measurement of particle concentration. Sand concentration is a major factor in finding the optimal operating condition, and pipeline sampling is believed to be an accurate approach to detect...

... Abstract Analysis of particle-laden fluid flow near an individual perforation (and assuming the fracture is only being fed by this one perforation) showed that the efficiency of particle transport to the fracture (ratio of particle concentration in the fracture and in the wellbore) depends...
