COLOSSUS UNC Uncemented Liner Hanger System

Unconventional completions such as slotted liners, screens, multistage stimulation, and steam injection

Uncemented liners are usually deployed with unconventional completions. The Long Reach integral liner hanger packer combines the liner hanger and packer on the same mandrel; both are set simultaneously, maximizing system integrity and simplifying operations. The system’s hydraulic setting capability, combined with its push, pull, and rotation capabilities, allows controlled liner deployment without excessive workstring manipulation.
