Stability and conductivity of proppant packs during flowback in unconventional reservoirs: A CFD–DEM simulation study

We present simulations using a coupled Computational Fluid Dynamics–Discrete Element Method (CFD–DEM) approach for a slurry of millimeter-sized particles in water which is squeezed between two walls and then made flow out though a narrow aperture. …

Numerical simulation of proppant transport in a planar fracture. A study of perforation placement and injection strategy

We present numerical simulations, based on a CFD–DEM approach, of the transport and settlement of proppant in a planar vertical cell that mimics a hydraulic fracture. These simulations, with resolution at the particle level, allow for a clean …
