description Methods and apparatus for completing wells and gravel packing an interval of a wellbore use a perforated shroud (20) having an internal sand screen (21) disposed therein. Particulate material is injected into the annuli between the sand screen and the perforated shroud and the perforated shroud and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. The perforated shroud has a flow-controlling means for restricting fluid movement between the casing/shroud and shroud/screen annuli during gravel packing.
