Deepsea Yantai
Negative Planning LL with Wellesley
Carmen (35/10-10S) – Surface section
What happened:
The centralizers was placed close to the bottom of the casing joint and was difficult to handle on the drill floor with the monkey tail.
What was planned:
To run casing with centralizers
What was learned:
To place the centralizers approx. one meter longer up, towards middle of the joint, for easier handling on rig floor
What actions are required:
To inform the service company delivering the centralized joints to place the centralizer further up from the pin (0.5-1 m).
