Hydraulic Set Liner Packer
Liner-top packer + hanger, set when hung
Combines a liner-top packer with a liner hanger. Unlike typical weight-set packers, this tool's packing element is set when the hanger is hung — normally used for screen or slotted liners, and also for scab liners, with the liner-hanger packer as bottom packer and a weight-set packer as top packer straddling a damaged section of casing or perforations.
Uncemented scab liners don't permanently restrict casing ID since the packers can be retrieved by running a solid nut retrieving tool on a work string and picking up to release the packers and liner.
Features
- Hydraulic cylinders match or exceed liner hanger yield strength
- Debris wiper seals on hydraulic pistons
- Can be used as a tension packer when run inverted
- Lock ring ensures packing element remains set
