Liner hangers are downhole devices used to secure the top of a liner string to the existing casing or wellbore. Unlike conventional casing that runs continuity from the surface, liners provide a cost-effective way to extend casing without hauling full strings from the surface.
Liner hangers ensure the liner is mechanically anchored in place and provides a foundation for seal elements or cementing operations that follow.
When deployed properly, liner hangers help maintain wellbore integrity, support pressure containment, and provide a solid launch point for subsequent completion tools such as packers, plugs, and production assemblies.
Liner hangers for lease are installed on the top of a liner string and conveyed into the wellbore using drill pipe or coiled tubing.
Once the hanger reaches the target depth, a mechanical or hydraulic setting mechanism engages expansion slips or retractable elements against the casing wall, creating a strong anchoring point.
Delta Oil Tools’ liner hangers are engineered to set reliably and withstand the differential pressures and loads typical of production or injection zones. After placement, the liner string becomes a stable extension of the casing, ready for cementing, packers, or other completion hardware.
