Dual String Packer


The DualString Packer is a hydraulic set, mechanically held dual string production packer normally run above a single string hydraulic set or wireline set seal bore packer. Because no tubing manipulation is required to set this packer, the well head can be installed and flanged up before setting.

This packer is available with short string or long string setting capabilities and a variety of tubing connections. This packer is also adaptable for electrical submersible pump applications. This packer features a sequential upper slip release system designed to release each slip individually to reduce the pull required to release the packer. The angles on the upper slips and upper slip body result in the slips releasing smoothly from the casing.


  • Several short string options available: Solid connection (flat top), J-Latch (complete with scoop head), “C” Latch (Snap Latch – complete with scoop head)
  • Feed-through tubes can be added to most designs
  • Accessories: Adjustable unions, Telescoping unions
