03:15 - 05:15: Established circulation with 1. 44 OBM in 200 LPM steps up to 2000 LPM. Circulated one btms up volume m3) at 2000 LPM 40 bar loss free rate. Meanwhile held pre-job meeting for CMT job. Geoservices had black-out on their system.
05:15 - 06:00: Geoservices worked to restart their system. Meanwhile continued to circulate at 2000 LPM 40 bar.
06:00 - 06:45: Geoservices worked to restart their system. Meanwhile continued to circulate at 2000 LPM 40 bar.
06:45 - 07:15: Performed hand-over and held pre-job meeting for CMT job. Meanwhile continued to circulate at 2000 LPM 40 bar.
07:15 - 07:45: Pumped 6 m3 base oil and 15 m3 1. 55 SG tuned spacer using rig pumps at 2000 LPM 40 bar. Chased spacer to drill floor with 3 m3 OBM.
07:45 - 08:45: Released bottom dart for BTM plug. Kept 20 bar back pressure on top drive. Mixed and pumped 13. 1 m3 1. 90 SG CMT slurry at 800 LPM 30-50 bar. BTM wiper plug sheared at 180 bar. Displaced CMT to rig floor with 500 ltrs DW. Released top dart and pumped 1500 ltrs DW behind CMT. Top wiper plug sheared at 112. 6 bar.
08:45 - 09:30: Zeroed stroke counters for mud pumps. Continued displacing cement with 86. 8 m3 OBM at 2000 LPM 40 bar using mud pumps. Wiper plug sheared at 120 bar 3380 stks. Slowed down rate to 1000 LPM 16 bar approx 4 m3 prior to bump. No bump observed. Stopped after pumping 3980 strokes, theoretical volume 1/2 shoe track. No losses during displacement. Monitored for back pressure. None observed.
09:30 - 10:30: Flushed manifolds and broke off CMT hose to check for back flow.
10:30 - 13:30: Set seal assembly according to vetco procedure. Performed line test of surface line against fail safe valve to 290 bar 5 min. OK. 28 ltrs pumped and 28 ltrs bled back. Closed upper pipe ram and lined up TDS to trip tank to monitor for returns. Pressured up in stages to 207 bar below closed ram. Bled off pressure to zero. Opened rams and took 30 MT overpull MT on weight indicator). Closed ram and pressure tested seal assembly 35/290 bar for 5/10 min. Dropped 1. 5 380 ltrs pumped and 380 ltrs bled back. Reduced overpull to 3 MT. Rotated 4 right-hand turns and released padprt.
13:30 - 14:30: Cleaned and cleared rig floor of excess equipment. Held tool box meeting prior to LD CMT head.
14:30 - 15:00: LD CMT head STD. Dropped sponge balls and flushed string with 1000 LPM using OBM.
15:00 - 17:45: POOH with padprt from 140 m to OOH. Removed ps21 and installed master bushings. Measured lead impression block to be 1 3/4". Lo padprt.
17:45 - 20:15: Held tool box talk before RD handling equipment. Removed elevators and bails. Cleared drill floor of non essential equipment. Monitored well on trip tank. Transferred operation to f-5 NB 9 5/8" casing will be tested to 290 bar as parallel activity on f-5

24-hour summary: Circulated, pumped and displaced cement. Sat and tested seal assembly. LD CMT head. Released padprt and POOH. LD RT. Transferred operation to f-5.
