A method comprising a) providing a packer comprising a tubular mandrel, a swellable elastomeric body supported on the mandrel, and first and second end caps secured to the mandrel, each end cap having an inner bore therethrough and being positioned such that a first end of each end cap abuts an end of the swellable elastomeric body, wherein the first end of at least one end cap includes a strain absorbing undercut formed in the inner bore thereof; b) positioning the packer within a wellbore; c) providing a swelling fluid into the wellbore; d) forming a fluid seal against the wellbore with the swellable elastomeric body; and e) extruding the swellable elastomeric body into the undercut.

Strain absorbing downhole packer

A method for anchoring a casing string within a wellbore is disclosed. The method includes providing a casing string, where the casing string being generally tubular, and coupling a swellable elastomeric material on at least a portion of the exterior of the casing string. In addition, the method includes positioning the casing string within a wellbore, exposing the swellable elastomeric material to a swelling fluid, and sealing the swellable elastomeric material to the wellbore.

Swellable casing anchor

A swellable packer which includes a generally tubular mandrel having a central axis and an exterior cylindrical surface. The swellable packer further includes a swellable elastomeric body fixed to the exterior cylindrical surface of the mandrel, wherein the swellable elastomeric body includes a plurality of grooves and wherein the generally tubular elastomeric sleeve has a circumference and a thickness.
