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.
