Negative Equipment LL with Wellesley
Serin (35/12-7) – P&A
What happened:
Believed that the HP housing lock ring was not set or only partially set, alternatively it was accidently released due to the movements during cutting operations. During first cut at 384.10 m, HP housing came free of LP housing with 25 t overpull while cutting. Unable to reset (3 attempts). On POOH, cement evident around lock ring and landing shoulder. Suspected cement was holding the overpull until 20″ was cut.
What was planned:
Cut & Pull 20″ x 30″
What actions are required:
Awaiting report from DQ. Limit amount of overpull while cutting.
