SEAL BORE PACKERS
Target Completions T691
PRODUCT DESCRIPTION
The Target Completions T691 RaZor Single string hydraulic set double grip production packer. This high performance hydraulic set packer offers the reliability of the Optima Series permanent packer but can be retrieved easily without milling. The RaZor basic design is a cut to release hydraulic set removable packer, but the RaZor design has incorporated the Target Completions patent pending release system into the design of this tool allowing the slips to unset from the casing I.D. with less than 15,000 lbs tension.
The RaZor is a centerline out design improving the performance, interchangeability of parts, added gage rings allowing for specific casing weight reducing extrusion gap and increasing performance of the element system, improved releasing / upper slip system and adding the Target patent pending release system into the design. The RaZor also has a longer stroke cylinder section for customized element systems. The RaZor can be supplied with peek backups, custom element systems and materials for specialized HPHT applications.
RaZor can be set up to run:
- CUT TO RELEASE MANDREL (CHEMICAL OR BLADE CUT MANDREL)
- SHEAR RELEASE MANDREL (TYPICALLY 120,000 LBS SHEAR)
- WIRELINE RELEASE MANDREL (ALLOWS UNSETTING WITH W/L JAR )
(THE WIRELINE RELEASE MODE CAN ALSO CUT TO RELEASE OR SHEAR TO RELEASE)
OPERATION
Setting: Run packer to desired depth and pressure tubing string to the recommended set pressure and the packer will set shearing the setting shear pins, engage the slips into the casing wall and packing off the element system. The RaZor packer sets without any tubing manipulation, so tubing can be flanged up at surface before setting of the RaZor packer. The setting shear screws are field adjustable.
Release: Straight pick up of the tubing string will shear the releasing shear screws, further pick-up engage the mandrel pickup ring to the upper slip housing releasing the slips and removing the packer from the casing. The RaZor release modes are:
- Cut to release, continued pick up engaging the upper slips unsetting the packer
- Shear to release, continued pick up engaging the upper slips unsetting the packer
- Wireline release, continued pick up engaging the upper slip unsetting the packer
(wireline release can also be cut to release and shear to release)
