The 2nd Pilot Well / 1st multi-use well executed in June 2021 and the 3rd Pilot Well / 2nd multi-use well executed November 2021.  

The 3rd Pilot Well was a casing exit operation (13 3/8” casing 72# N-80) from a platform on the NCS. Operational planning and preparation were performed together with Equinor and their contractors for the milling services.

 

The tool was positioned 340m above bottom of the BHA at a deviation of 27 deg, 1330m MD and OBM 1.56 s.g. During a total of approximately 12h milling time a total collection of 839kg swarf/mud was collected distributed over 750 kg inside the Swarf Container, 60kg on the Magnet Sleeve and 29 kg on the string magnet positioned above the Swarfix® WCT.
