Fat Canyon (6306/3-1 S) – Top hole
What happened:
9 7/8″ pilot hole BHA received before spud but 17 1/2″ followed later. Had spudded well before 17 1/2″ BHA arrived.
What was planned:
Receive 9 7/8″ and 17 1/2″ BHAs together.
What was learned:
MWD/LWD crew have to programme tools on deck then follow up with QA/QC operations which have to be sent to shoreside support and verified. If both BHAs are on deck at the same time crew can prepare both prior to spud. Once drilling operations have started on the pilot hole, crew have to focus 100% on the LWD data being acquired, leaving little time to programme the next 17 1/2″ BHA.
What actions are required:
Ship 9 7/8″ and 17 1/2″ BHAs to the rig so both arrive together.
