Abstract
A packer adapted for thermal applications to provide sealing integrity between the tubing and casing in a subterranean well is disclosed in combination with a tubing anchor seal assembly for providing secured sealing integrity between the tubing and the seal bore of the packer. The tubing anchor seal assembly comprises an inner mandrel attached to the tubing string. Annular seals are disposed on the exterior of the mandrel. A latch prevents upward movement of the tubing anchor seal assembly relative to the packer, while downward movement is prevented by abutting shoulders. A concentric sleeve engages the seals and radial protrusions on the mandrel transmit longitudinal force to the seals trapped against the sleeve to energize the seals which need not be elastomeric.
