comments: Pumped baseoil in to tubing at 200 lpm to obtain underbalance in well. Pressure increased from 0,5 bar to 6,9 bar during displacement. Pumped a total of 10 m3. Took up/down weight 170/150 MT.

comments: Ran in and attempted to land TH in wellhead. Unable to enter PBR at 2615,4 m MD. Picked up and attempted several (12) times to enter PBR - negative. Set down max 7 MT. At last attempt, observed that string moved incrementallly (2-3 cm) for each time weight was set down. Discussed situation - meanwhile maintained ~5 MT downweight. Observed sudden drop in applied weight - stinger free to move downwards. Drained riser. Landed tubing hanger at correct datum mark. Observed pressure buliding up from 6 bar to 11 bar indicating sealstem travel.
