Tension Packer

Definition - What does Tension Packer mean?

A Tension Packer is a type of packer that is set by applying tension to a running string. These packers are less common than compression set packers due to the potential difficulties associated with their retrieval. However, in applications where there is insufficient string weight to set a compression packer, a tension packer is more efficient. It is generally used in the injection applications or where thermal shrinkage of the tubing is expected such as treating operations.

Petropedia explains Tension Packer

Tension set packers are also ideally suited for shallow wells where the tubing pressure is likely to exceed the annulus pressure. Some of the advantages of a tension packer include:

  • It has a simple setting and releasing procedure in a borehole.
  • It contains case hardened friction blocks with INCONEL springs.
  • It contains a fullbore mandrel.
  • It contains a secondary rotational release.
  • Its secondary rotational release can be adjusted at the site as well (on-field).
  • With the help of tension packers, the tubing can be left in tension, compression or neutral condition.
  • Tension packer lets the pressure equalization before unsetting the slips.
