Toppand East (35/11-5, 39/11-29S) – Top hole
What happened:
– Due to short length from bit to stab ( approx 0.5m) it is challenging to install master bushing between stab and bit.
– Short shank on top of stab (approx 90 cm) makes it impossible to set slips on shank above stab.
– Managed to install MB between bit and stab, but then the top og connection above the stab is to high for the HT to make up the connection. Managed to do it, but some parts of the dies of the HT back up clamp was partly on the 7 5/8″ XO.
What was planned:
26″ Cleanout assy from SLB. Challenging to M/U 7 5/8″ XO to 26″ clean out assy.
What was learned:
Need a premade minimum 3m pup on top of stab. Pup to be a part of the BHA.
What actions are required:
Needs to be implemented in Gnomoria 26″ Cleanout BHA.
