ABSTRACT:
A packoff (10) with an elastomeric seal ring (16) interposed between two metallic seal rings (12) and (14) with retrievable characteristics in the form of a relatively thin apertured curved cylindrical band (50) extending between the two metallic seal rings (12) and (14). The metallic band (50) is such that it does not interfere with the deformability of the elastomeric material when the packoff is set, but provides a mechanical connection between the upper and lower metallic rings (12) and (14) thus providing the packoff with retrievable capabilities.
