Below-Tension-Ring Rotating Control Device (BTR RCD)

Contain hydrocarbons during offshore MPD operations

The below-tension-ring rotating control device (BTR RCD) is used during drilling and tripping for making a seal around the drillstring, thereby containing hydrocarbons or other wellbore fluids and preventing their release to the atmosphere.

Pressure ratings for the sealed rotating system (SRS) and internal seals have been determined through in-house lab testing with a test plug installed.

Applications

  • Operations with an MPD and riser-gas handling (RGH) integrated riser joint
  • Drillships and semisubmersible rigs
  • MPD, pressurized mud-cap drilling, underbalanced drilling, and containment
  • Stand-alone operation, as part of the integrated riser joint, or the Schlumberger integrated deepwater MPD system

Advantages

  • Saves time during installation and removal of the SRS
  • Enables drilling to continue while isolating potentially harmful wellbore fluids
  • Prevents release of the SRS in the presence of wellbore pressure
  • Improves operational efficiency with redundant, reliable design that requires no wear sleeve
