Swab Cup Packoff Assembly

Pressure-tested in-house to stringent criteria

Our versatile swab cup packoff assembly helps you attain reliable hanger settings.

Innovative Features    

  • Robust design accommodates high-pressure testing       
  • Incorporated ball seat promotes reliable hanger setting                 

Applications        

  • Cementing packoff on small and cost-effective liner systems
  • Lower packoff on liner jobs using hydraulically set hangers

Deployment

Run together with a hanger setting ball seat, the swab cup packoff assembly allows for a hanger to be set without increasing the risk of formation damage which occurs when pressuring the entire liner for setting the hanger and expending the setting ball. The ball seat in the running tool string, in concert with the swab cup packoff assembly, allows for pressure to be maintained only in the workstring, therefore decreasing surge on the formation when the setting ball is expended.
