Model FS packer is a retrievable, high-performance packer primarily used as the top packer in gravel pack tool systems such as SZGP (Single Zone Gravel Pack), OTMZ (One Trip Multi-Zone), OHGP (Open Hole Gravel Pack). The packer is set by hydraulic setting tools and could be released by retrieving tools.
The key components include a centralizer, a set of bi-directional slips and packing element, a ball needs to be dropped into the service tool before pressurizing to the setting pressure. After the setting is complete, the service tool will be picked up to circulation position for gravel pack pumping.
Despite conventional application in gravel pack and standalone screen systems, FS packer could be also used for water shut-off, production and other purposes.
