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.
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 Weatherford suite of liner systems includes the IntegraLine® high-performance liner system with swage technology, which helps secure integrity in even the most critical conditions.
Our IntegraLine liner system comprises three main components of premium quality to meet your critical well needs. The SwageSet liner-top packer features a proprietary seal that is swaged to the host casing to provide a positive annular-pressure barrier at the liner top. The SwageSet polished bore receptacle (PBR) is made up to the top of the packer to form a pressure vessel. Available in rotating and static versions, the IntegraLine liner hanger provides a hanging capacity of up to 1,000,000 lb (453,592 kg). With these components, our high-performance system meets challenges in such demanding environments as ultradeepwater, extended-reach, and sour-gas wells with high pressure and temperatures.
