Abstract
A seal assembly is disclosed including first and second annular members mutually movable longitudinally to effect a first configuration in which the seal assembly is releasably anchored to a cylindrical body circumscribed by the seal assembly, and a second configuration in which the seal assembly is releasably anchored to a surrounding conduit. Sealing members are carried by the seal assembly to engage the enclosed cylindrical body as well as the circumscribing conduit. Operation of the seal assembly for movement between the first and second configurations is accomplished by manipulation of the cylindrical body which, with the seal assembly anchored to the conduit, is permitted limited longitudinal movement relative to the conduit and seal assembly while maintaining sealing engagement with the seal assembly. A disclosed embodiment includes a well seal assembly, or packer, for sealing a pipe string to a well conduit.
