Positive Operational LL with DNO
Norma (25/7-11 S) – Top hole
What happened:
Drawwork in landing mode. No change in hookload while cementing and displacing.
What was planned:
Drawwork in landing mode during 20″ casing cement job.
What was learned:
Good practice to have the drawwork in landing mode when using an inner-string stinger into the float to avoid it stinging out due to heave etc.
What actions are required:
Have the drawwork in landing mode when using an stab-in stinger for 20″ casing job.
