The Short Time Jetting Tool is a simple and robust wellbore clean-up tool and can be run individually or modularly as part of the OWS ArmRdillo™ Wellbore Clean-Up System. The Short Time Jetting Tool is designed to jet the BOP cavities to dislodge debris during wellbore clean-up operations.

Features

  • Single piece Mandrel
  • Available with slick OD, solid bladed Ribs, or removable Jetting Sleeve
  • Available in various OD’s to suit onshore, platform or sub-sea BOP stacks
  • Available with standard and high torque drill pipe connections
  • Typically open ported design with optional BHA shut-off
  • Adjustable jetting ports can be configured to select direction and total flow area
  • Can be quickly assembled redressed on location with simple hand tools

Benefits

  • Cost savings
    • Simple BHA shut-off, does not require the use of the TIW valve or bull nose
  • Integrity
    • Available with high torque connections reducing the need for reduced strength crossovers
    • Single piece mandrel with no internal connections for increased strength
  • Reducing Non-Productive Time
    • BOP cavities are known to collect debris and junk Jetting before installing the completion can prevent premature failures

Applications

  • Pre-completion wellbore clean-up operations before running in the hole, when pulling out of hole, or both
  • After milling operations to remove swarf which can damage the BOP rams and annular

Operational

  • The Short Time Jetting Tool is typically deployed immediately above the OWS XTractR™ Wellbore Filter Tool or other types of gravity junk baskets during BOP jetting to capture dislodged debris
  • It is also recommended to run a dedicated magnet below the Short Time Jetting Tool to capture additional debris, particularly after milling operations
  • Best practice recommends to function the rams and annular to help dislodge debris before jetting the BOP stack at 10 BPM while rotating slowly, making 3 passes
  • It is also recommended to reduce jetting to 5 BPM while passing the annular
  • The Short Time Jetting Tool can also be used to jet behind the wear bushing after it has been removed
