Tandem Packer

The Tandem Tension Packer provides an efficient and economical method of isolating multiple zones. This packer has been designed to be used as the upper packer(s) in single string tandem hookups, where a Retrievable Tension or Permanent Type Packer is used as the bottom packer.

The packer is available with either the high performance three element system or a more economical single element system.

Operation

Once the packers are in position the bottom packer is set in the usual manner. A 4,500 daN (10,000 lbs.) upstrain will shear the screws used to prevent premature setting of the Tandem Tension Packer(s). As soon as these screws shear, the packing element(s) packs off and remains packed off so long as the tubing tension is maintained.

The Tandem Tension Packer can be released by simply slacking off the tension and rotating to the right one half turn. This rotation moves the J-Pin into a position that prevents pack-off during retrieving operations.

The Tandem Compression Packer is similar to the Tandem Tension Packer except that it uses tubing compression to pack-off instead of tubing tension. It is designed to be used as an upper packer(s) in single string tandem installations where a Retrievable Compression or Permanent Type Packer is used as the bottom packer.

This packer is available with either the high performance three element system or a more economical single element system.

Operation

Once the packers are in position, the bottom packer is set in the usual manner. A Shear System in the Tandem Compression Packer used to prevent premature setting will shear, packing off the element. The packer will remain packed-off as long as the compression is maintained on the packer.

The packer is released by simply picking up on the tubing. The packer can then be reset and retrieved.
