Abstract:
Anti-extrusion devices, packer elements, and inflatable packers include shape memory polymer (SMP) materials to enhance the operation of a packer, a bridge plug, or other downhole isolation tool. Seal system use seals of various material including SMP materials as booster for the seal produced. Tool for flow shut-off and sliding sleeve applications use SMP materials to open or close off flow through a tool.
