Same-day deployment of specialized magnet reduces nonproductive time and fishing complications

MAGNOSHOE Magnet Recovers 1 kg of Large Swarf and Shackle Bolt in North Sea Well

Publication Date: 11/28/2016

After cementing a North Sea well, an operator dropped a 6-ton rated shackle into the 13 3/8-in casing. The oil company halted operations to assess the lost shackle and remove it as quickly as possible. The operator flow checked the well, pumped a slug, and racked back the bottomhole assembly (BHA) in preparation for the fishing package to arrive on location by boat.

To minimize nonproductive time, M-I SWACO proposed running the high-strength MAGNOSHOE magnet to retain heavy, oddly shaped debris. M-I SWACO airfreighted the tool immediately, allowing it to be run in hole the same day. The operator recovered more than 1 kg of large ferrous debris, including the shackle bolt, before the fishing package and personnel arrived at the rig.
