Liner hanger systemsfrom Baker Hughes provide a means to hang the liner in the previous casing string, enabling the liner to be cemented while in tension and providing a solid bottom against which to set a liner top packer.
Our liner hanger portfolio features both mechanical- and hydraulic-set hangers with options for ultrahigh hanging capacity, high bypass, and rotation while cementing. They can be deployed in moderate environments of 10,000 psi (689 bar) and up to 300°F (149°C) to extreme high-pressure, high-temperature (HP/HT) and HP, low-temperature (LT) conditions requiring a pressure rating up to 15,000 psi (1,034 bar) and 450°F (232°C).
The FLEX-LOCK V™ liner hanger is the latest version in the FLEX-LOCK-style hanger family and has been optimized for extreme downhole conditions such as heavy drilling fluids, high solids content, and liner rotation, to reach the desired setting depth. The FLEX-LOCK V offers a slip seat wedge profile and slip rail design for increased resilience to solids packing off and for greater hanging reliability. It is available with a rotationally locked option to prevent component back-off, yet can still be equipped with a bearing to allow for rotating after the hanger is set while cementing. A hydraulically balanced ControlSET™ hydraulic-set liner hanger is also available, which provides the ability for unrestricted circulation rates without risk of prematurely setting the hanger, and it is useful for ream-down or drill-down applications.
