Seminole Services launches new liner hanger

Published by
Oilfield Technology,


The PowerScrew™ liner hanger from Seminole Services utilises torsional energy from the top drive to efficiently and safely set a liner, eliminating any need for high pressure in the setting process.

In the PowerScrew’s setting mechanism, rotation of the top drive provides all of the energy required to helically stretch-form the liner top without the application of pressure. This unique mechanical setting process provides a liner top that’s ISO 14310 V0 rated, for improved pressure containment, increased hanging capacity, and an overall higher standard of reliability and safety.

The PowerScrew features a simple design with fewer components, combined with its unique torsional setting process, for ease of operation and a high degree of reliability and functionality. This liner hanger’s patented stretch-forming technique provides a superior connection between drilling/production liners and intermediate casing strings. Additional features of the PowerScrew’s liner top includes profiled packer elements and hardened slip wickers for reliable hanging and sealing performance. In addition, this advanced system’s running tool delivers superior tensile, compressive, and torsional strength, providing for successful deployment and target placement of the liner in any well profile. Currently, Seminole has inventory and equipment for setting inside 9 5/8 in. & 7 5/8 in. intermediate casing.
