Abstract of the Disclosure Disclosed is a hydraulically operable well packer for releasable setting within a well conduit, including a seal assembly for sealing the packer to the conduit and an anchor assembly for anchoring the packer to the conduit. The seal assembly includes sealing members for engaging the conduit as well as secondary sealing members for engaging a central mandrel of the packer, both sets of sealing members being constructed of material which permits the mandrel to remain sealed to the well conduit in the presence of high temperatures. The packer may be released by straight longitudinal movement of the mandrel relative to the outer packer assembly.
