Systems and methods are provided for swellable material activation and monitoring in a subterranean well. A sensor system for use in a subterranean well includes a swellable material, and at least one sensor which is displaced to a wellbore surface in response to swelling of the swellable material. Another sensor system includes a sensor which detects swelling of a swellable material. A swellable well tool system includes a base pipe, a swellable material on an exterior of the base pipe, and eccentric weighting for inducing rotation of the swellable material about a longitudinal axis of the base pipe.

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.

Shunt tube flowpaths extending through swellable packers

A swellable packer with composite material end rings. A packer assembly includes at least one generally tubular seal element extending longitudinally between opposite ends thereof. At least one end ring is positioned proximate one of the seal element opposite ends. The end ring includes a nonmetal material. A method of constructing a packer assembly includes the steps of: chemically bonding at least one end ring to a base pipe; providing at least one generally tubular seal element which extends longitudinally between opposite ends thereof; and restricting longitudinal displacement of the seal element relative to the base pipe utilizing the end ring positioned at one of its opposite ends.
