Abstract
A swellable packer includes a base pipe; a swellable sealing element disposed around the outer diameter of the base pipe; and at least one internal backup ring disposed within the swellable sealing element. It may be manufactured by disposing the internal backup ring on the base pipe; applying an elastomeric material over a section of the base pipe and the internal backup ring; and applying a bonding agent over the section of the base pipe and the at least one internal backup ring. It may be used to isolate a section of a well by disposing a swellable packer in the well, and exposing the swellable packer to a fluid, wherein the fluid exposure causes the elastomeric material to radially expand into contact with a well wall.
