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 fit the casing ID, while being stiff enough to provide strong scraping force which ensures true 360° coverage where sprung pad scrapers cannot
• Tungsten carbide cement mill is attached to the tool mandrel to mill cement and other debris
• Two fluted Centralizer Rings provide centralization and protects the Scraper Broach
• Free rotating tool design with Internal Bearing Rings to prevent mandrel, 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

• Combines the functionality of the RazRdillo™ Casing Scraper with the ruggedness of an aggressive fixed blade string mill
• Milling of cement and scraping can be performed in a single trip saving rig time

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

Applications

• Drilling hardened cement, and other accessories inside the wellbore in a single trip
• Pre-completion wellbore clean-up operations to remove hardened cement sheath, scale, mud solids, cuttings and other detritus from the casing wall
• 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 MunchRdillo™ Scraper Broach scrapes the casing wall removing cement sheath and other debris
• Cement plugs and accessories can be drilled inside the casing as required following standard cement drilling practices and parameters
• The MunchRdillo™ mill breaks up any large cement pieces or debris that is carried past the tool into smaller more manageable pieces
• The MunchRdillo™ is reamed across the drilled out cement depths to remove any residual cement sheath in a single trip saving valuable rig time
