Brasse Appraisal (31/7-2 S) – Surface section
What happened:
During M/U 18 3/4″ WHH, threads got cross threaded from side to side when moving the 18 3/4″ WHH. Troubleshoot same. Where able to unscrew 18 3/4″ WHH by lifting with top drive and at same time use casing tong.
What was planned:
Make up 18 3/4″ WH incl. 20″ ext. joint and 13 3/8″ XO to the 13 3/8″ csg
What was learned:
During planning phase: Plan to use a “NO X COUPLING” as a box on last 13 3/8″ casing joint prior to P/U 18 3/4″ WHH. This will help to stabilize the long 18 3/4″ WHH assembly. This is especially a good help if the rig is heaving/moving.
What actions are required:
