Tension Tubing Hanger

Overview Library

Robust through-BOP solution to set tubing strings in tension

The Cameron tension tubing hanger's unique two-piece tensioning mechanism is ideal for all completion applications, including natural flow, gas lift, and artificial lift systems in onshore and offshore wells. To continue producing, conventional and unconventional wells will eventually use artificial lift, requiring the tubing string to be placed in tension.

The tension hanger is a two-piece tubing hanger that allows the tubing to rotate independently from the parent bowl, assisting in setting the packer and locking the tubing string in tension. The lockdown mechanism is an integrated J-Slot retention mechanism with positive stops.

Tension Tubing Hanger

Advantages

  • Operational advantages: Tensioning capacity up to 80,000 lbf with 10,000-psi blind load test prevents tubing wear and decreases the effects of thermal expansion and buckling within the wellbore. Tubing centralizer mitigates seal wear during installation and the lifting thread is rated for full connection strength.
  • Versatility: The tubing hanger can be run as a conventional hanger or a tensioning hanger in various bowl profiles.
  • Cost savings: Ability to use a single tubing hanger and adapter for all completion activities results in operational savings. No specialized running tools are required. 
  • Safety: Through-BOP operations eliminate BOP removal and reduce the time spent working below the rig floor. A positive integrity test can be achieved prior to BOP nipple down. Integral positive stops assure proper lockdown.
  • Range of sizes and pressure ratings: Rated for pressures up to 10,000 psi, the tension tubing hanger system is available for nominal wellhead sizes ranging from 7 1/16 in to 11 in and above, with tubing sizes ranging from 2 3/8 in to 2 7/8 in, 3 1/2 in, 4 1/2 in, and more.
