comments: Gauged and inspected bit and BHA. Upper stabilizer had 1/32'' wear. In addition it was ringed out with a 4cm high and 2-3mm deep cut all around the stab approximately 1/3 from the bottom of it. The hard facing was still in place. The lower stab was worn 1/16''. Also here the hard facing was in place. Bit grading: 2-2-WT-S-IN-HC, some wear also on bit body. B/O bit and M/U new 12 1/4" bit.
