RazRdillo™ Casing Scraper

The RazRdillo™ Casing Scraper 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 RazRdillo™ Casing Scraper 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 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
