What happened in Intermediate section:
Commander 1000 is a very heavy CMT-head. Due to its weight, it is not preferable to use on DSY unless it is needed. It is preferred to use Commander 500, as it is less risky to have it racked in Derrick and it takes a lot less time to move with Hydraracker (HR). HR moves in slow mode due to the weight. There is also limited space to grip the Commander 1000, therefore we need to lift C-1000 stand under the CMT-head causing the load to wobble a bit. This also cause more strain on HR.

What Was Planned

Cement 13 3/8″ Casing using Commander 1000 cement head,

What Was Learned

Use Commander 500 in future operations.
