Negative Equipment LL with Wellesley
Serin (35/12-7) – Production section
What happened:
Had to lay out several joints due to missing threads on top of pin ends, (9 5/8″, #53.3, P-110, VAM21). On some sides on top of pin end, threads were totally missing. Ovality was also measured on some pin ends. Suspected manufacture fault. Pictures were taken and 4 joints were rejected from rig floor during MU, 21 joints were rejected on deck after inspection. (total of 16 jnts, 10% of casing sent out).
What was planned:
Make up 9 5/8″ casing
