4-1/2 x 7″ Powerscrew Assembly

See E&P magazine’s 2018 Shale Technology Showcase, July issue, page 54.  To view the published brief: print or online.

Seminole Services, LLC offers metal formed liner hangers to advance shale drilling and completion operations through well construction and well integrity tools.  Designed specifically for shale operators, our recently developed 4-1/2 x 7 in. PowerScrew™ Liner Hanger allows longer liner runs, larger completion tools, and priority placement of pressure activated equipment in a production string.

Our tool was created to minimize reliability risks while offsetting  costs associated with other expandable hangers and long-string casing designs.  Also, with our patented mechanical setting process, safety risks from high pressure, high compression loads, and cone extraction have been engineered out of the tool, creating more value than cost savings alone.

5-1/2 x 7-5/8 Powerscrew Assembly

Seminole Services has commercialized a second Powerscrew Liner System.  Sized to set inside 7-5/8 intermediate casing, our next stretch formed liner hanger will provide more opportunities for operators in applications requiring 5in. or 5-1/2in. liners.  Driven by market demand, the new system has incorporated several improvements which allow for quicker assembly, better rig handling, and more versatility in sizing different intermediate casing weights.  The tool has been rigorously tested and qualified under ISO 14310 (API 11D1) with a V0 rating. Oiltool Engineering Services performed the third party testing service at their laboratory in Willis, TX .

Seminole Services installs first Powerscrew Liner System!

Catoosa Well, Lucy 6G; Hallet OK….Seminole Services successfully installed a 7-5/8 39lb liner inside a 9-5/8 32.3lb intermediate casing string after reaming the liner to total depth.  A rotating cement head was utilized during the job to better facilitate the cementing operation.  The liner top was forged downhole through the use of a unique helical stretch forming technique that utilizes torsional energy from the top drive.  With a drop in torque, the liner top was fully integrated into the 9-5/8 casing and the setting tool retrieved from the well.  A perfect first run!
