Abstract: This paper reviews the latest advances of numerical simulation for gravel packing in horizontal wells. The discussions focus on the following topics: gravel packing process mechanism and technology; calculation model for equilibrium bank height and critical velocity in packing. A description is made on slurry flow in screen/wellbore annuli, carried fluid flow in wash-pipe/screen annuli and fluid transfer between two flow system and fluid leak-off into formation. The mathematical model for bank height in $\alpha $ wave packing, factors affecting horizontal well gravel-pack efficiency and existing problems are also discussed.
