<comments>Observed higher up weight to get string in movement - 520 klbs. Dropped to 470 klbs when we had movement in sting.  Attempt to break connection with Unitong, not able to brake connection with 97 kft/lbs. Inspected dies on unitong - found dies in ok condition. Rotated string frequently with top drive to confirm free string.  Ran back in hole and broke off top single and laid out to deck. 

Flow checked well 15 min while attempting to break connection and inspecting dies in unitong - well stable. </comments>

<comments>Continued to POOH with 5 1/2" DP from 4425 m to 3845 m wet. Observed similar force(520 klbs) to get stand number two in movement. Up weight dropped to 470 klbs while pulling.  Observed weight increase 20-40 klbs when pulling through Lower sele/Forties/Upper sele/Balder (4038-3902 m). Worked through area by running back in to confirmed free string and pulled back through with flickering weight.
