ABSTRACT:
A sealing system, particularly useful for packers and anchors, is disclosed. The sealing element or elements are of a nonelastomeric material and are configured with a feature that can add a biasing force on one or both sides of the nonelastomeric sealing element(s) to allow the sealing element(s) to maintain the seal despite temperature or pressure fluctuations in the wellbore. The apparatus allows a packer with a nonelastomeric seal to be set at a broad range of downhole temperatures. The system includes a biasing member in the form of a cylindrical element having narrow width and wider width openings.
