MAGStar4™ HD Casing Magnet

The MAGStar4™ HD Casing Magnet is a robust, high strength, super capacity casing magnet with a free-rotating centralizer. It can be run individually or modularly as part of the OWS ArmRdillo™ Wellbore Clean-Up System. The MAGStar4™ HD Casing Magnet can be adapted to suit any casing size and drill pipe combination.

Features

  • 3 longitudinal ribs houses rows of high strength and temperature resistant Rare Earth magnets
  • Excellent bypass area and carrying capability
  • Debris is securely retained for retrieval at surface
  • Single piece mandrel for superior strength in heavy duty and high torque applications
  • Optional non-rotating Centralizer minimizes casing and tool wear
  • Magnets are securely retained in integral slots with redundant back-up for maximum security
  • Easily cleaned at surface to allow re-running in the hole
  • No external bolts, clamps or fasteners that can come loose downhole

Benefits

Cost savings

  • High Density magnet arrangement requires less tools and less runs to clean the wellbore during heavy milling operations

Increases Well Productivity

  • A properly executed wellbore clean-up removes ferrous debris which can block screens or interfere with sensitive completions equipment

Integrity

  • High strength mandrel with no internal connections for strength and reliability
  • Available with any proprietary high torque connections eliminating the need for crossovers which reduce string integrity

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 ferrous debris
  • Drill out of completion equipment
  • Post-milling operations
  • Riser/BOP clean-up

Operational

  • The MAGStar4TM HD Casing Magnet can be run standalone or part of a wellbore or riser/BOP clean-up string
  • The MAGStar4TM HD Casing Magnet is typically run above scrapers  and/or filter debris recovery tools in a wellbore or riser/BOP clean-up
  • Whilst running in hole the active magnets will attract and retain and ferrous material
  • During displacement the drillstring can be rotated and reciprocated to improve hole cleaning efficiency without fear of damage to the casing, drillpipe or MAGStar4TM HD Casing Magnet
