09:45 - 10:00: Evaluated situation. Meanwhile greased and checked dies on IRN.
10:00 - 10:15: POOH w/ RTTS on 5 1/2" DP from 788 m to 645 m.
10:15 - 11:00: Changed BX inserts to 5". L/d the RTTS and safety joint.
11:00 - 11:30: P/u and m/u 3m pup for space out. Pulled master bushing and installed PS-21 slips.
11:30 - 12:15: RIH w/ EZSV RT on 5 1/2" DP from 648 m to 854 m Avg. Tripping speed 275 m/hr. Tagged EZSV w/ 2 ton to confirm depth.
12:15 - 12:45: P/u and m/u pump-in sub. Stung into EZSV and set down 10 ton. Connected cement hose and installed lo-torque valve to pump-in sub.
12:45 - 14:30: Closed UPR lined up and pumped 10m3 push pill at 1000lpm 12 bar. Circulated SW at 1000-1800 LPM 12 bar until clean returns. Meanwhile performed TBT for cement job.
14:30 - 14:45: Opened UPR and flow checked well, static.
14:45 - 16:45: Lined up and pumped 20m3 wash pill at 1285 LPM 11. 5 bar. Closed upper FOSV and trapped 20 bar behind. Applied 20 bar from cement unit to drill floor and confirmed line-up. Pumped 33 m3 1. 90sg cement slurry at 600 LPM. Added well-life to the first 10m3 of cement slurry kg/m3). Chased cement by pumping SW at 1000 LPM 12 bar. After catching up with cement, continued displacing cement with SW at 1000 LPM 12 bar, then reduced rate to 800 LPM the last 1. 7m3. Pumped totally 11. 7m3 SW. Pressure increased from 12 bar to 47 bar, indicating that cement entered annulus. Recorded 1. 8m3 losses during displacement. Estimated TOC in annulus at 480 mmd.
16:45 - 17:15: Released from EZSV plug and rigged down cement hose. L/d pump-in sub.
