Features

• Strong, self-sprung, single piece Scraper Broach machined from a single billet of steel with multiple rows of overlapping teeth
• Scraper Broach flexes to perfectly fit the casing ID, while being stiff enough to provide strong scraping force which ensures true 360° coverage where sprung pad scrapers cannot
• Two fluted Centralizer Rings provide centralization, bypass and protects the Scraper Broach
• Free rotating tool design with Internal Bearing Rings to prevent drill pipe, tool or casing wear
• Can be quickly assembled redressed on location 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 ScourRdillo™ 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 tools need to be run on the same string

Operational

• While running in hole, the teeth of the RazRdillo™ Scraper Broach scrapes the casing wall removing cement sheath and other debris
• Cement plugs can be drilled inside the casing as required
• The RazRdillo™ is reciprocated across critical depths to remove hardened 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
