retrievable packer

1. n. [Well Completions]

A type of packer that is run and retrieved on a running string or production string, unlike a permanent production packer that is set in the casing or liner before the production string is run. Retrievable packers are most commonly used in well intervention activities, although some completion designs are more suited to retrievable packers than permanent packers.
