Negative Planning LL with Faroe
Rungne (30/6-30) – Intermediate section
What happened:
The 5 1/2″ DP handling pup made up to the 9 5/8″ casing hanger running tool was too short. The length was 3.89 m. With this length, the shear ram will cut into the tooljoint of first 5 1/2″ DP single made up this pup.
What was planned:
Running 9 5/8″ casing
What was learned:
This means that the shear ram can’t be used during the cementing operation. No issue if the 5 1/2″ handling pup had been 0.5 m longer.
What actions are required:
DQ to look at the BOP spaceout drawing when planning & providing handling pup to the RT for future wells.
