Liner Systems


Liner Systems inspecting liner

Wells with extreme temperature ranges and high-pressure differentials can cause equipment failure and, in turn, threaten well integrity with costly consequences. These environments require robust, reliable liner systems that can get the liner to total depth safely and efficiently while withstanding harsh conditions.

Liner systems reduce costs by eliminating the need to extend a single, long casing string all the way up to the top of the wellbore. Instead, casing can be suspended inside the previous casing string to reduce material cost and provide greater flexibility when selecting the completion.

Liner Systems north sea

Originally developed for harsh North Sea environments, Weatherford liner systems have evolved to succeed in quality-critical applications such as deepwater, shale, HPHT, and other tough well construction environments.

Our integrated liner-hanger, running-tool, and cementing systems are supported by our highly trained professionals and job involvement from planning to execution.

Weatherford is a true single-source, liner-hanger provider with equipment for virtually any application.

We combine our experience with liner-hanger, cementing, drilling, and tubular running products all under one roof. We improve system capability by designing and manufacturing every component of our liner-hanger systems and cementing equipment in-house. Our integrated product and services portfolio helps you reach total depth reliably, safely, and cost effectively.

The SwageHammer™ integrated liner-hanger system

The SwageHammer™ integrated liner-hanger system delivers the benefits of both conventional and expandable liner-hanger technologies in an easy-to-install, unibody platform.

In conditions where wellbore integrity is critical and the cost of failure is high, our SwageHammer system reduces uncertainty and risks. Engineered to the strictest sealing requirements and tested to ISO 14310 V0 criteria, the system is validated for safe operation up to 400°F and 12,500 psi (204°C and 86.2 MPa). The highly reliable gas-tight seal provides security in harsh high-angle, extended-reach, deepwater, and HPHT wells. The all-in-one body eliminates the hydraulic cylinder, ports, and internal seal—and the leak paths common to conventional liner hangers. Most importantly, the pressure-balanced running tool enables rotating, reaming, pushing, pulling, and drilling the liner to TD while withstanding premature setting or release. 


We deliver a comprehensive portfolio, plus engineering and executional experience, that helps get you to total depth safely and efficiently.
