What is liner hanger systems? 

Definition:

Liner Hanger is a tool/system that is used to hang a liner in a production well.Liner is similar to casing. But it is not run to the full depth of the well. As casing Liner hanger systems , it could be mechanical or hydraulic, premium or standard, rotating or non-rotating, conventional or expandable and pocket slip.

  We has been providing specialized tools to the oil and gas industry for over a century. Our liner hanger systems, designed to work in every well condition, have been used around the world on some of the deepest and most difficult wells, on state-of-the-art horizontal completions and in deep water applications or where customers simply want the most reliable completion equipment available.

  Our Liner Systems are available in expandable, hydraulic and mechanical settings. It can be configured for rotation, reaming or drill down capabilities.

  Our product portfolio includes liner packers, liner hangers, setting tools and accessories, surface cementing equipment, down hole cementing accessories such as port collars and stage cementing tools and tieback equipment.

  The Consists Of a Liner Hanger Systems

1 Liner HangersExpandable Liner Hanger System is designed to run with standard liner applications and incorporates industry-proven expandable technology to provide a liner top anchor/sealing device unmatched in the industry.We also offers a variety of mechanical and hydraulic set liner hangers, available in both single and multi-cone models. Our liner hangers are engineered to provide superior performance and dependability in well circumstances such as high load capacity, fluid bypass and collapse resistance.
2Liner Top PackersRun with the liner hanger, liner top packers provide a positive liner-to-casing seal at the liner top, reducing the possibility of formation breakdown, fluid loss and gas migration in both low and high-pressure applications. We manufactures a variety of liner top packer models for specific service requirements from low to moderate applications as well as high-pressure and extreme environments. Packoffs are available in various material and design to meet the environment and pressure requirements.
3Setting CollarsSetting collars provide a connection point for the drill string and setting tool to carry the liner load while running the well. The setting collar usually will contain profiles for the cement bushing as well as profiles for rotation of the liner assembly. In most cases the setting collar includes a tie back receptacle for future liner extension.
4Setting Tools & AccessoriesWe offers an extensive variety of setting tools and accessories designed to provide a variety of down hole functions and allow operators multiple operational options when deploying liners. Whether the need is simply to carry the liner in the hole, set right hand mechanical hangers, rotate and/or ream liners or hydraulic release for horizontal wells, We has the right tool to meet these requirements.
5Surface EquipmentCement manifolds, used at the surface, allow fluids to be pumped into the liner and cement displacement plugs to be dropped. TIW’s surface equipment is designed to support tension loads from drill pipe and liner, and to support a Top-Drive Drilling System or a power swivel as the drill string power source.
6Tieback EquipmentTieback equipment allows existing liners with a receptacle to be extended to the surface or farther up hole, and provides a high-pressure seal at the top of a cemented or uncemented liner. We offers variety of tieback seal nipples and tieback packers to accommodate liner top extension and remedial operations.
Casing hanger. In petroleum production, the casing hanger is that portion of a wellhead assembly which provides support for the casing string when it is lowered into the wellbore. It serves to ensure that the casing is properly located.
Tie-Back Liner. Tie-back is a string to connect a liner back to well head. It is fairly common for oil and gas wells and they almost always run for geothermal with sometimes 2 on one well. Depending on where the wellhead is, the liner can betied back to rig floor (platform) or seabed.
