... The simulation results presented in Fig 6 show that in the inner annulus (between the wash pipe and the perforated liner) the mud is relatively easily displaced by the breaker. The mud and the breaker are both water based miscible fluids although the mud is non-Newtonian and more than two open...

... the screen was on depth prior to pumping gravel pack fluid. In order to achieve efficient fluid displacement, thorough simulation and analysis were run. For sand control strategy, open hole alternate path system was selected in combination with Visco-elastic Surfactant (VES) gravel carrier technology...

... and a conventional DDS at 190 degF is shown in Figure 5 . Model for Degradable Diverter The model adopted to simulate the DDS was developed by Cohen et al. in 2010 . It is based on the extra skin introduced to the near wellbore region by the diverter as it plugs the perforations in a cased and perforated...

The differences in well performance is studied for each case, and analytical equations for the skin factor resulting from each scenario are presented. The anisotropic wormhole networks are obtained from numerical simulations using...
