comments: Investigated issue with DHSV.
Kept 520 bar on DHSV control line and bled of pressure from well through closed drain. Monitored pressure on DHPG and observed pressure dropping 1 bar / 10 min while bleeding off well. Closed bleed-off valve and observed DHPG pressure increase, indicating that DHSV was in open position.

comments: Staged up rig pumps to 1300lpm/71bar and bullheaded remaining 6,2m3 of wash pill followed by 208 m3 SW.
Meanwhile: Performed TBT for cement job.

After bullheading 118 m3 of SW the pressure increased from 71 bar to 91 bar rapidly. Continued bullheading SW at 1300lpm, pressure stabilized at 90 bar with a slightly decreasing trend.
After bullheading 208 m3 of SW the pressure increased again from 90 bar to 100 bar rapidly. Pressure stabilized with steady trend at 100 bar.

comments: Displaced cement with 41,5 m3 SW from cement unit at 1300 lpm / 85 bar, cycled DHSV 3x after bullheading 30 m3 of SW (while still pumping at 1300lpm).

Continued displacement by pumping 3 m3 contamination pill at 600lpm / 56 bar with cement unit. After bullheading 2,7 m3 contamination pill the formation started to pack off, pressure increased from 56 bar to a final squeeze pressure of 95 bar. Stopped pumping, final static pressure 57 bar.
Estimated TOC 2700 mMD.
