MunchRdillo™ Scraper Milling Tool // Casing Size 4 1/2" Connectors 2 7/8 HT PAC PIN x 2 7/8 HT PAC BOX

MunchRdillo™ Scraper Milling Tool is a robust 360° contact free-rotating wellbore clean-up tool that combines the function of a scraping element and a heavy duty mill on one tool mandrel, which can be run modularly as part of the ArmRdillo™ Wellbore Clean-Up System.

The MunchRdillo™ can be adapted to suit any casing size and drill pipe combination.

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
