Integrated Liner Hanger Tieback System
Metal-to-metal, gas-tight system
Solve problems with long casing strings by connecting a liner to a tieback string with full V0-qualified casing integrity.
Remove excessive compression and tensile loading from the hanger and tieback seal, extending their use by deploying the metal-to-metal load anchor.
The load anchor is set against the previous casing above or below the hanger to mange the compression load. It can also be used to prevent movement of the tieback casing to help maintain the integrity of traditional seal stacks and PBR systems.
As a part of the COLOSSUS M2M metal-to-metal expandable liner hanger system portfolio, the load anchor system provides full metal-to-metal anchoring of tieback casing, effectively enabling the use of conventional liner hanger equipment that would otherwise be unable to support the heavy axial loads.
The unique Metalmorphology metal-to-metal sealing and anchoring technology shapes metal downhole so it conforms perfectly to the shape of the upper casing string.
