ABSTRACT:
A packer element for use in forming a fluid pressure barrier within a wellbore. The packer element uses a thermoplastic component to accomplish the seal against the interior diameter of a surrounding tubular and an energizing component that is preferably formed of elastomeric material. The thermoplastic component of the packer element provides a sealing surface and defines an energizing chamber within. An energizing chamber is defined within the thermoplastic component and contains energizing elements that, when axially compressed, will urge the sealing surface of the thermoplastic component into sealing engagement with the surrounding tubular.
