Shunt tube flowpaths extending through swellable packers. A well system includes a packer assembly including a base pipe and an annular seal element which is swellable in response to contact with a selected fluid, and a shunt tube flowpath extending through the seal element for delivery of a slurry in a gravel packing operation. A swellable packer assembly includes a base pipe; a swellable annular seal element having a shunt tube flowpath extending through a swellable material; and a valve connected to the flowpath and positioned within the swellable material. Another well system comprises a packer assembly including a base pipe and an annular seal element which is swellable in response to contact with a selected fluid; a shunt tube flowpath extending through a swellable material of the seal element; and a connection between the flowpath and a shunt tube assembly, the connection being positioned within the swellable material.

Passages découlement en dérivation sétendant à travers des garnitures gonflables. Un système de puits selon linvention comporte un ensemble garniture comprenant un tube de base et un élément de joint annulaire susceptible de gonfler en réponse à un contact avec un fluide choisi, et un passage tubulaire découlement en dérivation sétendant à travers lélément de joint afin damener une bouillie lors dune opération de gravillonnage. Un ensemble garniture gonflable comprend un tube de base ; un élément de joint annulaire gonflable comportant un passage tubulaire découlement en dérivation sétendant à travers un matériau gonflable ; et une vanne reliée au passage découlement et positionné à lintérieur du matériau gonflable. Un autre système de puits selon linvention comporte un ensemble garniture comprenant un tube de base et un élément de joint annulaire susceptible de gonfler en réponse à un contact avec un fluide choisi ; un passage tubulaire découlement en dérivation sétendant à travers un matériau gonflable de lélément de joint ; et une connexion entre le passage découlement et un ensemble tube de dérivation, ladite connexion étant positionnée à lintérieur du matériau gonflable.
