ReGen Fullbore Liner Top Packer

ReGen Fullbore Liner Top Packer

  Onshore        Field-proven Technology
The REGEN™ Fullbore Liner Top Packer (FLTP) is an advanced slim hole HPHT compression-set packer designed to remedy any leak between the liner and parent casing without the requirement of costly cement squeezes. 

The REGEN™ FLTP can be run either as an integral component of the primary liner system, or run separately using an anchor latch system, offering compatibility with both new and existing REGEN™ Liner Hanger system installations. It delivers a HPHT annular seal between the top of the liner hanger and casing, while delivering best in class ID for standard frac plugs in all refrac operations.

  1. Reduces hydrostatic on the cement, helping to avoid losses in the liner lap
  2. Protects liner tops during the most demanding refrac operations
  3. Custom elastomeric seal ensures seal integrity at moderate temperatures and pressures
  4. Metal-to-metal sealing system ensures seal integrity at high temperatures and pressures
  5. Bonded element prevents swab-off while running and cementing
