Chased spacer to drill floor with 3 m3 OBM. Lined up to pump from CMT unit. Opened lo-torque valve with 20 bar on CMT line to verify line-up. Released BTM dart for BTM plug. Mixed and pumped 23. 25 m3 1. 90 SG silica CMT slurry at 800 LPM 32 bar and 7. 0 m3 g-cmt slurry at 800 LPM/ 20 bar.
06:00 - 07:30: Displaced CMT to rig floor with 500 ltrs of DW at 1000 LPM. Released top dart and pumped 1500 ltrs at 1500 LPM behind CMT using CMT unit. Top wiper plug sheared at 158 bar after 750 ltrs pumped. Lined up through to top drive and zeroed stroke counters on mud pumps. Continued dispacing CMT by pumping OBM at 3000 LPM. Sheared BTM plug at 7219 strks 8 m3) 155 bar. Reduced rate to 1200 LPM at 8400 strks 7 m3). FCP was 53 bar. Bumped top plug at 8552 stks 0 m3) 142 bar.
07:30 - 09:15: Pressured up surface lines to 140 bar to equalize and open lo-torque on CMT head. Attempted to close IBOP. No go. Bled off pressure to 95 bar, closed IBOP and continued to pressure up CSG to 345 bar. Bled off standpipe pressure to 25. 7 bar and monitored for leak through IBOP. Performed pressure test of 13 3/8" CSG to 345 bar 15 min, OK. Bled back pressure to 20 bar and monitored for back flow. No back flow observed. 2. 9 m3 pumped and 2. 9 m3 bled back.
09:15 - 14:00: Sat seal assembly according to vetco procedure. Landing string dropped 8 1/4". Performed line test of surface line against fail safe valve to 345 bar 10 min. OK. Closed lower 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. Pumped 350 ltrs and got 300 ltrs back. Opened rams and took 45 MT overpull. Closed ram and pressure tested seal assembly 35/345 bar for 5/10 min. Dropped 3. 5 bar 15 min. 550 ltrs pumped and 450 ltrs bled back. Reduced overpull to 3 MT. Rotated 4 right-hand turns and released.
14:00 - 15:45: LD CMT head STD. Dropped sponge balls and flushed string with 4400 LPM using OBM.
15:45 - 16:30: POOH with padprt from 135 m to OOH. Removed ps21 and installed master bushings. Measured lead impression block to be 1. 7". Lo padprt.
16:30 - 20:30: MU and RIH with wear busing and WBRT. Washed well head and installed wearbusing at 139. 3 m. POOH with WBRT and lo jet sub and WBRT.
20:30 - 22:30: MU jet sub to HWDP and RIH from surface to 40 m. PU and MU 18 3/4" BOP test plug. RIH with BOP test plug on 5 1/2" DP from 40 m to 175 m and landed off test plug in wearbushing.
22:30 - 23:00: Halliburton prepared unit prior to testing.
23:00 - 00:00: Pressure tested BOP and ibops to 20/345 bar 5/10 min.
