Deepsea Yantai
N/A Planning LL with DNO
Norma (25/7-11 S) – P&A
What happened:
It was not clearly stated in the HLB cement program how the cement calculations should be carried out other than use of Enhanced method. After discussion with HLB onshore it was decided to calculate the cement/displacement with enhanced method placing the stinger above the cement+ excess cement. What previously done is to calculate the cement op with placing the stinger above the cement (not including the excess)
What was planned:
The cement calculations to be done according to HLB cement Programme for the P&A and KO cement for mainbore.
What was learned:
It should be clearly stated and agreed beforehand how to calculate the cement calculation to avid confusion.
What actions are required:
It should be clearly stated and agreed beforehand how to calculate the cement calculation to avid confusion.
