Case Study Arkansas: New CT MAGNOSTAR Magnet Recovers Plug Slips in Milling Operations
The CT MAGNOSTAR magnet recovered 2 lbm [0.91 kg] of fine metal shavings and pieces of the plug slips, some of which were longer than 1 in [2.54 cm].
The CT MAGNOSTAR coiled tubing magnet from M-I SWACO is the industry’s only 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.
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 MAGNOSTAR 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 MAGNOSTAR 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.
The CT MAGNOSTAR 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.
