UniFlex Pro liner hanger/packer system
The UniFlex Pro™ liner hanger-packer is the industry’s first integral liner hanger/packer system for cemented liner applications. It is built on a one-piece mandrel with no internal connections for added dependability. External moving parts are rotationally locked to the body, preventing back-off of threaded outer components, even if demanding conditions call for extensive rotation to reach bottom.
The UniFlex liner hanger includes a hydraulic-set FLEX-LOCK hanger section to provide maximum hold-down capacity and a ZXP liner packer to ensure maximum seal integrity. The liner packer has a single, premium threaded connection at the bottom of the tool. The UniFlex Pro version offers an ISO 13410 V0-qualified liner top seal that can be used when a gas-tight annular barrier is required. The UniFlex ControlSET version includes redundant hydraulic cylinders that allow circulation at high rates while drilling or reaming in a liner; this eliminates the risk of prematurely actuating the hanger slips.
