ScourRdillo™ Casing Brush // Connectors NC38 PIN x NC38 BOX Hole Size 7"

The ScourRdillo™ Casing Brush is a robust, 360° free rotating contact, wellbore clean-up tool and can be run individually or modularly as part of the ArmRdillo™ Wellbore Clean-Up System.

The ScourRdillo™ Casing Brush can be adapted to suit any casing size and drill pipe combination.

Features:

• Multiple overlapping wire brush elements which provides 360° contact with the casing wall and generous fluid bypass area for circulation

• Two fluted Centralizer Rings provide centralization, bypass and protects the brush elements

• Free rotating tool design with Internal Bearing Rings to prevent drill pipe, tool or casing wear

• Can be quickly assembled redressed on location or support base with simple hand tools

• No external bolts, clamps or fasteners that can come loose down hole

• Robust assembly method with multiple back-ups

Benefits: Cost Savings

• The ArmRdillo™ Wellbore Clean-Up System has incremental cost savings on logistics, deck space, inspection and maintenance and can also be serviced at the rig-site with basic hand tools Increases Well Productivity

• A properly executed wellbore clean-up reduces fine debris which can block screens and pore throats reducing well productivity Integrity

• The ArmRdillo™ Wellbore Clean-Up System can be provided with any type of rig end connections including premium and high torque connections reducing the need for reduced strength crossovers

• Single piece mandrel with no internal connections for increased strength Reducing Non-Productive Time

• A robust wellbore clean-up is proven to reduce nonproductive time during the completion of the well

• Reduces premature failure of completion equipment by debris which can interfere with valves, electronics and other hardware

Applications:

• Pre-completion wellbore clean-up operations to remove hardened cement sheath, scale, mud solids, cuttings and other detritus from the casing wall

• Typically run as a complement to the RazRdillo™ Casing Scraper for superior hole cleaning

• Drilling casing cement plugs in a single trip

• Extended reach wells where high strength drill pipe connections are required

• Remote locations where logistics are constrained and tool maintenance can be performed at the rig site

• Short tripping where multiple brush tools need to be run on the same string

Operational:

• While running in hole, the Brush Elements of the ScourRdillo™ scour the casing wall removing cement sheath, scale and other debris

• Cement plugs can be drilled inside the casing as required

• The ScourRdillo™ is reciprocated across critical depths to remove cement sheath and other debris

• During displacement the drill string can be rotated and reciprocated to improve hole cleaning without fear of damage or wear of the casing, drill pipe or of the ArmRdillo™ Wellbore Clean-Up System
