What happened in Surface section:
The box end of the 13 3/8″ no cross coupling is too long to allow the use of the casing running tool (CRTi). Measured the CRTi and the length of the box on NCC, found out 15cm of dies before the CRTi comes into contact with the casing.

What Was Planned

13 3/8″ no cross coupling is picked up prior to making up the 18 3/4″ HPWHH

What Was Learned

The CRti was rigged down and the BX-3 elevator was used for this one casing joint

What Actions Are Required

Ensure it is captured in future DOPs to rig down the CRTi and install the BX elevator and rig up the casing tong to M/U the NCC joint
