Hybrid Lock Mandrel - Annulus Bore

Download Spec Sheet

  • Hybrid Lock Mandrel Web

The Oilenco hybrid lock mandrel is a high performance well isolation barrier that uses our mechanical expanding hybrid seal technology.

The lock mandrel provides a 'best of both worlds' approach as it has the integrity assurance of a bridge plug sealing element, but with the simple operation of a conventional lock mandrel.

The hybrid sealing technology ensures that the seals are run below gauge of the hybrid lock mandrel. Once located in the well bore, the hybrid lock mandrel is set and the seals energised by downward jarring. This engages the locking keys in the profile and allows the seals to energise in the seal bore.


  • Bi-directional sealing and integrity assurance due to proven sealing technology
  • Seals run under gauge to prevent damage to seals during setting
  • Reduced run requirements - 1 run to set and 1 run to recover
