Abstract
The present disclosure relates to a releasable anchor, which may be used in a thermal wellbore, such as a SAGD wellbore. The anchor may be combined with a retrievable packer assembly that mechanically locks and seals into a profile sub. The packer assembly can convert to a bridge plug and be run in place with a liner to isolate the wellbore during the liner setting stage or it can be run into a pre-installed profile sub during a work-over stage in conjunction with a production/injection string to divert flow through a particular section of production liner string. The packer assembly may then be retrieved, and the hydraulic anchor released, allowing movement as a result of any thermal liner pipe expansion, while the thermal element on the liner top packer stays set and sealing within the parent casing.
