Hourly activities:
00:00 - 01:00: Balanced cement plug m 2580 m mixed and pumped 9,2 m3 of 1,9 SG cement slurry, 630 l/min. Displaced the cement to the rig floor with 2900 l of drill water. Zeroed volume counters. Displaced the cement with 30,7 m3 strokes) of SW, 2000 l/min/ 3 bar.
01:00 - 01:45: Pulled out of cement to 2295 m MD. Theoretical TOC 2330 m MD.
01:45 - 03:00: Installed sponge ball, m/u TDS, pulled to 2287m. Pumped 10m3 of hi-vis pill. Circulated total of 74m3 at 2700lpm-38bar until clear returns observed.
03:00 - 03:15: POOH from 2287m to 2219m.
03:15 - 04:45: Installed BOP jetting tool, washed BOP cavitied with 1450lpm, 8bar, made 5 passes. Function tested BOP and washed another 5 passes.
04:45 - 05:45: POOH from 2215m to 1843m.
05:45 - 07:45: Removed ps21 slips and r/u casing pulling equipment
07:45 - 08:00: Performed pre-job meeting for pulling tubing
08:00 - 08:30: Broke swage, r/b stand of drill pipe and changed BX elevator inserts
08:30 - 13:45: POOH with 7in tubing from 1816m to 1366m joints or 450m of tubing), removed clamps and spooled control line. Average pulling speed 7. 2 joints/hour, MAX pulling speed 10 joints/hour. Cut control line and secured to tubing with clamp on the last joint. Observed fluid spraying out of control line
13:45 - 14:00: Performed pre-job meeting for engaging spear and r/d casing pulling equipment. Observed fluid spraying out of control line
14:00 - 14:30: Crimped control line to stop fluid spraying out. Removed spooler and scaffold shelter from setback area
14:30 - 15:00: P/u spear and engaged in 7in tubing. RIH w/ spear below rotary to change slips
15:00 - 16:30: R/d casing equipment and installed ps21 slips. Removed tong from frame in preparation for next operation. Meanwhile change BX elevators out for offline inspection and inspected and greased 10 3/4in grapple
16:30 - 17:15: Serviced both prss
17:15 - 17:30: Cleared rig floor, meanwhile installed inserts in BX elevators. Doped pipe in derrick
17:30 - 19:00: RIH w/ tubing on spear to 2278m. Avg. Tripping speed 680 m/hr.
19:00 - 20:15: Washed down from 2247m to 2320m with 560l/min and 6 bar. Did not find hard cement. Decreased flow to 222lt/min 1. 2bar and continued to wash down to 2359m
20:15 - 21:30: POOH from 2359m to 2335m and circulated bottom up with 1350l/min 53bar and then increased to 2020l/min 109bar. In the end of circulation some loose cement was observed in the shakers along with consolidated clumps of cement. Otherwise mostly clean fluid in returns. Meanwhile recalculated BHA figures after discrepancy was found
21:30 - 22:30: Washed down from 2335m to 2420m with 560l/min 7,4 bar. Did not encounter hard cemtent. 60m left to go before hitting minimum length of plug 2480m). When making connections observed back flow from DP indicating heavier fluid in annulus
22:30 - 00:00: POOH from 2420m to 2398m and circulated BTM up with 2020 l/min, 106bar. Reduced flow just before BTM up due to possible cement in returns. After BTM up increased flow to 2660 l/min and 180bar and continued to circulate. Observed some loose cement in returns on shakers.

24-hour summary: placed balanced cement plug in 9 5/8 CSG pulled 450m of 7in TBG OOH and l/d same RIH w/ remaining 7in TBG on spear, attempted to tag cement
