04:30 - 04:45: Performed pre-job meeting for displacement annulus behind 13 3/8in CSG,
04:45 - 07:00: Circulated annulus behind 13 3/8in CSG to clean sea water, increased flow rate from 250 to 1250lpm, pumped 2 bu or total of 144 m3, until clear sea water confirmed in returns. Observed h2s of MAX 14ppm on baker sensor in gas trap. No h2s in air measured on gas sensor in shaker room. Treated returns with sourscav to remove h2s and soda ash increase ph) to prevent forming new h2s
07:00 - 07:45: Flow checked well on full opened choke static. Opened UPR and continued monitoring well on trip tank. Static. Meanwhile performed TBT for cement job
07:45 - 08:15: Performed line test prior to cement job to 100 bar. Good test. Checked line up, prepared for pumping cement job
08:15 - 10:00: Cement plug in annulus between 13 3/8in CSG and 20in CSG. Theoretical height from 850m to 450m Pumped 20 m3 of wash pill, 1200 l/min/ 13 bar. Mixed and pumped 35 m3 of 1,9 SG cement slurry, 600 l/min. Displaced the cement with cement unit with 11 m3 of drill water, 1200 l/min, pumping pressure went up to 50 bar.
10:00 - 10:30: Stang out of EZSV w/ running tool, p/u 3. 5m above EZSV. Balanced cement plug. Theoretical height from 840m to 740m Mixed and pumped 7,7 m3 of 1,9 SG cement slurry, 600 l/min. Displaced the cement with cement unit with 7,8 m3 of drill water, 800 l/min, pumping pressure of 10 bar.
