1. n. [Well Workover and Intervention]
A type of retrievable packer used in squeeze-cementing operations. Key features include a bypass system and hold-down slips. The bypass system prevents surge and swab effects when running and retrieving the packer and enables circulation of the cement slurry to the proximity of the packer before closing the bypass for injection into the treatment zone. The hold-down slip assembly enables application of high squeeze pressure without the risk of the packer unsetting or moving up the wellbore.
Synonyms: squeeze tool
