The RizeRdillo™ Advanced Jetting Tool combines jetting action with flow-rate boost effect to maximize riser cleaning efficiency.
Features
- Jetting Sleeve with 9 x offset Jetting Nozzles arranged to jet the riser wall and also to penetrate into the BOP cavities to jet and clean
- 9 x upward angled Jetting Nozzles arranged on the body help to reintroduce jetted debris into the flow path and be carried upwards to surface
- Optional integral pup joint for fast handling
- Optional lower bull nose or pin down connection to suit various applications
Benefits
- Cost Savings
- Maximizing riser cleaning efficiency to reduce operating time and costs on expensive semi-submersibles
- No field maintenance required
- Integrity
- Available with high torque connections minimizing the need for reduced strength crossovers
- Single piece mandrel with no internal connections for increased strength
- Reducing Non-Productive Time
- Reduces premature failure of completion equipment by debris which can interfere or damage valves, electronics and other hardware
Applications
- Deep water pre-completion wellbore clean-ups from semi-submersible drilling units
- Riser cleaning during displacement to sea water before disconnection or moving from location
Operational
- The RizeRdillo™ Advanced Jetting Tool is typically run in conjunction with the RizeRdillo™ Riser Cleaning Tool and XTractR™ BOP Junk Catcher or as a standalone tool
- While jetting in the hole, the Jetting Sleeve washes the riser wall. The staggered jetting nozzles allows full coverage without the need to rotate
- Best practice recommends to function the rams and annular to help dislodge debris before jetting the BOP stack at 35 BPM while rotating slowly, making 3 passes
- It is also recommended to reduce jetting not lower than 20 BPM while passing the annular preventor
- The RizeRdillo™ Advanced Jetting Tool can also be run with a wear bushing retrieval tool below
- The upward angled Jetting Nozzles assist in carrying debris to surface through inducement of turbulent flow
