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
