UltraMag™ HD Casing Magnet

The UltraMag™ HD Casing Magnet is a highly robust, high-capacity casing magnet with free-rotating upper and lower centralisers. It can be run individually or modularly as part of the OTL Wellbore Clean-Up System and can suit any casing size and drill pipe combination.


  • Three longitudinal ribs housing rows of high-strength and temperature resistant Rare Earth magnets
  • Magnets can be removed to enable full MPI inspection of the mandrel
  • Excellent bypass area and debris retrieval capability
  • Debris is securely kept within the longitudinal ribs for retrieval at the surface
  • Optional non-rotating Upper & Lower Centralizers providing centralisation and minimise casing and tool wear while improving magnet efficiency


  • Cost savings
    • UltraMag™ offers superior debris retrieval with fewer runs to clean your wellbore due to the design and increased length of the tool
  • Increases Well Productivity
    • A well-executed wellbore clean-up removes ferrous debris, which can block screens or interfere with sensitive downhole completions
  • Integrity
    • High-strength mandrel with no internal connections for strength and reliability
    • Available with any proprietary high-strength connections eliminating the need for crossovers which reduce string integrity
  • Reducing Non-Productive Time
    • High-performance magnets are recognised for helping to reduce non-productive time during the completion of the well
    • Reduces premature failure of completion equipment caused by debris which can interfere with valves, electronics and other downhole equipment


  • While tripping or circulating, the UltraMag™ HD Casing Magnet attracts ferrous debris from the wellbore and captures it for removal at surface
  • Heavy-duty milling/drilling operations, fishing and workovers can be performed utilising the UltraMag™ HD Casing Magnet in the string.


  • The UltraMag™ HD Casing Magnet can be deployed immediately below the wellhead when jetting BOPs to capture any dislodged ferrous 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 UltraMag™HD Casing Magnet
