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 MAGStar4^TM HD Casing Magnet can be run standalone or part of a wellbore or riser/BOP clean-up string
• The MAGStar4^TM 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 MAGStar4^TM HD Casing Magnet
