Remove metallic debris during coiled tubing operations
The CT MAGNET STAR coiled tubing magnet from SHARP RAZOR magnet designed to extract the ferrous debris during coiled tubing cleanout operations. During demanding coiled tubing milling operations, the CT MAGNOSTAR magnet removes heavy metallic debris that cannot be circulated out of the wellbore.
Rely on high strength for a variety of CT challenges
This high-strength, rare-earth magnet is typically fitted above or behind the coiled tubing motor, where it attracts plug slips, metal swarf, and other ferrous material. Available in 2 7/8-in and 2 3/8-in sizes, the CT CT MAGNET STAR magnet can be used with coiled tubing while cutting windows, drilling out plugs, milling stuck isolation valves, or performing a routine cleanup run. Featuring a one-piece full-strength mandrel, CT MAGNET STAR magnet can also be used in fishing operations to collect ferrous debris outside of the standard annular gap via specially designed valleys in the tool.
Meet high-flow and ball-drop requirements
The CT MAGNET STAR magnet is engineered to meet the demands of operations requiring high flow rates and ball drops. It’s through-bore design with a large ID allows balls to be dropped to disconnect a sub below and enables circulating at a high rate whenever necessary.
The tool is run above the motor and collects ferrous material in the valleys of the tool where the high strength rare earth magnets are
located. The design ensures the debris is not “blown” from the magnet area or scraped off as the BHA is removed from the well. The use
of rare earth magnets also allows the tool to maintain a high magnetic field at higher temperatures where common magnets will rapidly
lose their magnetic field.
The C CT MAGNET STAR magnet is added to the BHA, preferably on top of the motor, and is run in the wellbore where the milling operation
is carried out without any changes. Once the CT MAGNET STAR magnet is pulled out of the hole the metallic debris is removed using a
non-magnetic tool. The debris is then classified and weighed.
It is recommended to run as many CT MAGNET STAR magnets as needed to capture the expected debris that will be generated during the
milling operation. This will help prevent the metallic debris from reaching the BOP and lodging in its cavities.
