What happened in Surface section:
XBAT was run on 17 1/2″ BHA regardless.

What Was Planned

Run XBAT(sonic) on 17 1/2″ only if sonic data from pilot hole wasn’t good enough.

What Was Learned

17 ½” XBAT was M/U and racked prior to completing pilot hole (with XBAT installed).
Criteria for running 17 ½” XBAT should have been included in RAP. Both onshore and offshore organisation failed to follow up on the requirement for running the XBAT.

What Actions Are Required

It must be clearly stated in RAP/DOPs the criteria for running the XBAT.

On,- and offshore needs to be attentive to this in the future.
