UltraPak TH Permanent Hydraulic-Set Packer

Weatherford’s UltraPak TH permanent packer, a robust, high-performance
tool, is designed for single-trip, high-differential-pressure, single- or
multiple-zone applications, in straight to highly deviated wellbores. The top
and bottom premium thread connections allow connection of the packer
directly to the tubing string, thus eliminating the need for a threaded latch
anchor.
The UltraPak TH packer has passed rigorous ISO 14310 testing.
Performance rating envelopes display combination loading from pressure
and axial loads.
For more than 40 years, Weatherford has manufactured and installed
packers for operations around the world. The success of the UltraPak
series of packers and accessories is a result of their reliability and
performance in a broad range of operating environments.
Applications
• High-pressure production or testing
• Fracture stimulation
• Monobore applications
• Highly deviated wells and doglegs
• Applications with large flow volumes
Features, Advantages and Benefits
• One-piece mandrel, with premium top and bottom tubing connections,
eliminates the O-ring connection between the mandrel and bottom sub,
thereby eliminating leak points and providing greater reliability.
• One-trip setting requires no rotating or reciprocation of the tubing string,
saving rig time in running and setting the completion.
• Dual O-rings on the hydraulic setting system provide extra protection
against failure from O-ring leakage.
• Large packer bore reduces restriction to maximize flow rates and provide
free access to the reservoir for wireline tools.
• The UltraPak TH packer is fully envelope-tested to ISO 14310.
Options
• An external test clamp is available, which permits testing of the packer
before it is run in the hole.
• Elastomer options are available for hostile environments.
