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
