• Over/Under Stripper Packer

    Description

    Our over/under design has two independent packers that are compressed by independent pistons. This setup eliminates the need for the tandem packer, which reduces the overall stack height. A pressure chamber between the packers can be used to inject lubricants or inhibitors during coiled tubing operations, extending the life of the packer.

    Features/Benefits

    • Compact profile
    • Packers can be operated independently
      • Snub into well with either packer
      • Utilizes one packer while the other is held in reserve. When first packer is unable to affect a seal, the second packer is actuated, thus doubling the time between packer changes.
      • If the primary packer wears out, the secondary packer can be activated to complete the job.
    • Pressure chamber between packers for lubricating coiled tubing, monitoring pressure and monitoring inhibitor injection
    • Long-life bushings
    • Replaces standard side door and tandem side door packers
    • Side door provides easy access to replace the packers
    • Provides dual barrier instead of a single barrier which increases safety
