Workover Risers

Our completion/workover risers system allows increased recovery rates and optimum well productivity levels.


 

Completion / Workover Risers solutions

Tenaris’s completion/workover risers system grants our customers free access to the wellbore from the workover rig deck. This allows increased recovery rates and optimum well productivity levels.

Working in deep and ultra-deep water environments, completion/workover systems must be able to withstand extremely high dynamic loads and challenging environments (sour service and HP/HT). Also, a workover riser column may be built several times in order to work in different fields, which requires a connection capable of withstanding several make-and-break cycles.

To guarantee these requirements, we offer:

  • Heavy wall thickness pipes with upset ends, 90 ksi and 100 ksi steel grades suitable for sweet or sour service applications.

Tenaris experience

Tenaris has provided upset pipe for workover risers for the following sour and non-sour projects:

  • Ormen Lange for FMC Technologies with 90 ksi steel grade tubes and 31.45 mm wall thickness (WT) in the upset
  • Tyrihans for FMC Technologies with 100 ksi steel grade tubes and 37.7 mm WT in the upset
  • Vega for FMC Technologies with 100 ksi steel grade tubes for sour service and 37.7 mm WT in the upset

We also supplied Threaded and coupled solutions for Statoil in the Norne project with 8 5/8“ 68 pound per feet P110 grade tubes and TenarisHydril Wedge 563™ connections.
