DH-1 Liner Running Tool

Pressure-balanced lock sleeve helps you set liners with confidence

Use the DH-1 liner running tool to drill down or ream the liner to the desired depth. The liner may be pushed, pulled and rotated while running into the hole without fear of premature release.

Innovative Features

  • Pressure-balanced activating lock sleeve prohibits premature release during ream-down       
  • Primary hydraulic release       
  • Secondary mechanical release
  • Large ID for increased surge reduction

Deployment

Release the DH-1 through hydraulic activation with right-hand workstring rotation (primary) or through torque activation (secondary). Circulation pressure cannot cause premature release.
