Hourly activities:
00:00 - 00:45: RIH with 10 3/4" CSG from 2574 to 2617 m MD. Filled every joint with 1. 40 SG mud using FAC tool. Average running speed 4-5 jnts/hr. Up weight 261 MT down weight 193 MT.
00:45 - 02:45: RD FAC tool and changed bails. Changed to 5 1/2" HWDP hadling equipment.
02:45 - 05:30: PU and MU 10 3/4" casing hanger padprt assembly. Marked running tool to make sure it is not backing out. Took out master bushing and ran hanger assy through rotary. Re-installed master bushing. Removed CSG tong.
05:30 - 06:00: RIH with 10 3/4" x 9 5/8" CSG on 5 1/2" HWDP landing string from 2626 to 2698 m MD.
06:00 - 06:30: RIH with 10 3/4" x 9 5/8" CSG on 5 1/2" HWDP landing string from 2698 to 2740 m MD.
06:30 - 07:15: PU cement head and broke circulation in steps up to 2000 LPM, 500 LPM 20 bar and 2000 LPM 56 bar
07:15 - 07:45: RIH slowly and landed off hanger. Observed 10 MT drag prior to landing off. Pumped 500 LPM and observed weight dropped off.
07:45 - 09:00: Circulated 1 CSG volume with 1. 40 SG OBM at 200 LPM 57 bar. Meanwhile hed pre-job meeting for CMT job.
09:00 - 09:30: Lined up and pressure tested CMT line 245 bar 5 min. Verified correct line-up by holding and releasing 10 bar through low torque.
09:30 - 10:15: Pumped 10 m3 base oil and 20 m3 spacer at 2000 LPM 48 bar. Mixed and pumped 17,3 m3 1. 90 SG cement slurry at 800 LPM 40-45 bar.
10:15 - 12:15: Pumped 490 ltrs water, released dart and continued pumping 400 ltrs water behind cement with CMT unit, to displace surface line volume to rig floor. Zeroed stroke counters for mud pumps. Displaced and sheared wiper plug by pumping OBM at 1200 LPM using rig pumps. Wiper plug sheared at 138 bar 886 ltr. Continued displacing cement with 102. 8 m3 OBM at 2000 LPM using mud pumps. Slowed down rate to 1000 LPM 33 bar approx 4 m3 prior to bump. Bumped plug with 110 bar after pumping 4718 strokes, which gives a pump efficiency of 95. 3
12:15 - 13:45: Bled off pressure to 20 bar and closed IBOP. Equalized pressure and opened lo-torque valve. Pressured up well to 310 bar 10 min through lo-torque valve to test casing. 1300 ltrs pumped and got 1350 ltrs back. Bleed off and checked for back flow to CMT unit. Disconnected CMT hoses and flushed lines.
13:45 - 14:30: Lined up top drive to trip tank to monitor returns. Tested surface lines against fail safe valve to 207 bar 10 min. Closed upper pipe ram and applied 207 bar to set seal assembly.
14:30 - 15:00: Took 40 MT overpull. Attempted to pressure test seal assembly without sucess.
15:00 - 17:30: Released padprt, lo cement head and 2 jnts of 5 1/2" HWDP. POOH with running tool on 5 1/2" HWDP landing string from 120 m to OOH.
17:30 - 22:00: RIH with BOP test plug to 139 m to test MS seal. Closed upper pipe ram. Attempted to pressure test seal assembly to 35 bar 5 min without sucess. Closed annular to test upper pipe ram and found that upper pipe ram was leaking. Closed lower pipe ram and pressure tested seal assembly to 35 bar 5 min and 345 bar 15 min. 463 ltrs pumped and got 450 ltrs back. POOH with BOP test plug.
22:00 - 00:00: RIH and installed wear bushing at 139 m MD.

24-hour summary: Landed 10 3/4" x 9 5/8" CSG. Circulated, pumped and displaced cement. Sat seal assy, but could not get a good test. Released padrt and POOH. LD CMT head and 12 1/4" BHA. RIH with test plug to 139 m and tested MS seals. Installed wear bushing. RIH and sat 10 3/4" RTTS w/storm valve.
