• Subsea Triple Stripper

    The DZA4 Subsea Modular 3 Window Stripper Packer is designed to pack-off on coiled tubing as it is stripped in and out of the well at working pressures up to 10,000 psi.

     

    Description

    This design provides three independent hydraulically-actuated packers within the same body, allowing you to utilize one packer while the others are held in reserve. When the first packer is unable to affect a seal, the second packer is actuated. Once the second cannot affect a seal, the third packer is actuated.

    This effectively triples the time between packer changes. Changing packers is always easier, but it is particularly advantageous when changing packers with tubing in the well. The stripper is designed to create a dynamic seal around the work string while maintaining 10,000 psi full differential well bore pressure. With the appropriate packing element and bushings the stripper will be compatible with pipe sizes ranging from 1" to 2 ⅞". The unique aspect of this design is it is a modular concept, each additional packer required is just adding it into the stack.
