The RizeRdillo™ Riser Cleaning Tool combines brushing, wiping and debris extraction technology on a robust mandrel to effectively clean subsea drilling risers.
Features
Rows of overlapping brushes to scour the riser wall to remove debris
Heavy duty elastomeric wiper rings to wipe mud cake
Large fluid bypass area to circulate debris to surface
High capacity gravity junk basket to capture debris for retrieval at surface
Soft blade stabilizers to prevent riser wear
Can be quickly emptied for re-run
Brushes and wipers can be redressed quickly onsite if required
No external bolts, clamps or fasteners that can come loose down hole
Benefits
Cost Savings
Maximizing riser cleaning efficiency to reduce operating time and costs on expensive semi-submersibles
Field serviceable at the rig with basic hand tools
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
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™ Riser Cleaning Tool is typically run in conjunction with the RizeRdillo™ Advanced Jetting Tool and XTractR™ BOP Junk Catcher or can be run as part of a pre-completion wellbore clean-up string
The RizeRdillo™ Riser Cleaning Tool brushes and wipes the riser wall whilst running in the riser to capture debris that can not be circulated out easily
When the riser is displaced the RizeRdillo™ Riser Cleaning Tool can be rotated and reciprocated to assist in the cleaning action
The gravity junk bucket collects debris which cannot be circulated out of the riser for retrieval at surface
