Methods and apparatus provides an improved shunt nozzle which is part of an alternative pathway for a slurry to by-pass an obstruction such as a sand bridge during gravel packing. The nozzle includes a hardened insert that lines a surface of an aperture in a shunt. A jacket secured to the shunt receives the insert, which is trapped from movement relative to the jacket.

Appareil et méthodes concernant une buse de dérivation améliorée qui fait partie d'une voie alternative permettant à une boue de contourner une obstruction, par exemple un pont de sable, lors d'une opération de gravillonnage. La buse comporte une pièce d'insertion durcie qui recouvre la surface d'un orifice dans la dérivation. Une gaine fixée à la dérivation reçoit la pièce d'insertion, ce qui en empêche tout mouvement par rapport à la gaine.
