comments: Pumped into the well 3m3 50/50 mix of MEG and sea water, 5 bar, 10m3 wash pill, pressure equalised at 58 bar above DHSV. Continued pumping sea water. Pressure 60-80 bar, 1300l/min. Pressure gradually increased to 150bar. After 180m3 pumped (2x well volumes) shut down pumps. Monitored SIWHP for 20 min. Pressure down to 24 bar.

comments: Continued bullheading into the well w/ 1300l/min, pressure stabilized at 170bar, slowly decreasing to 165 bar. After 360m3 pumped (4x well volumes) shut down pumps. Monitored SIWHP for 15 min. Pressure down to 48 bar.

comments: Continued bullheading into the well w/ 1300l/min, pressure stabilized at 175bar, slowly decreasing to 170 bar. After 630m3 pumped (7x well volumes) shut down pumps. Monitored SIWHP for 15 min. Pressure down to 60 bar. Meanwhile evaluated situation, discussed w/ duty team onshore.

comments: Continued bullheading into the well w/ 1300l/min, pressure stabilized at 182bar. Meanwhile carried out TBT for cementing operation. After 200m3 pumped (2,2x well volumes) shut down pumps. Monitored SIWHP. Pressure down to 95 bar. Confirmed w/ duty team onshore and continued with cementing operation. Totally bullheaded into the well 1370m3

comments: Released bottom dart. Mixed and pumped 27.6m3 of 1.9sg cement slurry at 800l/min. Pressure 116 bar, decreasing to 40bar, indicating cement moving down in the tubing. Displaced lines w/ 0,9m3 of Hi-vis pill. Released top dart. Pumped 7,1m3 of Hi-vis (totally pumped 8m3 of Hi-vis). Displaced w/ 50,4m3 of sea water at initial rate of 1200lpm. Pressure gradually increased to 150bar and then rapidly increased to 260bar, indicating plugging off perforation w/ cement slurry. Started reducing pumping rate in steps to keep pumping pressure below 270 bar. Reduced rate from 1200l/min to 170l/min. Pumped  3m3 of contamination pill, pressure at 260bar. Shut down pumps and monitored WH pressure decline. Recorded final stabilized squeeze pressure of 40bar. Closed swab valve. 
Verified volumes pumped by checking volumes left in the pits and silos. Theoretical top of cement 3172mMD. DHSV was cycled several times after 35m3 of sea water displacement was pumped
