Hourly activities:
00:00 - 01:00: Continued drilling cement in shoetrack from 1355 m to 1358 m MD. Drilling parameters 4000 LPM SPP 130 bar 90 RPM 3-5 MT wob torque 16 KNM.
01:00 - 04:15: Drilled cement in rathole from 1358 m to 1367,5 m MD. Drilling parameters 4000 LPM SPP 131 bar 50-80 RPM 3 MT wob torque 15 KNM. Reamed back to shoe for every 2 m drilled. Reamed through shoe without rotation last time no obstructions. Performed toolbox talk prior to displacement.
04:15 - 05:45: Displaced well to 1,35 SG performadrill KCL mud. Pumped 25 m3 hi-vis followed by 30 m3 of drillwater and 220 m3 1,35 SG performadrill. Pump rate 2000-4000 LPM SPP 80-190 bar rotation 20 RPM. Closed dumpline valve and routed interface mud to pit#12.
05:45 - 06:00: Routed mud returns to pit#7 and circulated on closed system. Picked up single 5 1/2" DP for drilling rathole.
06:00 - 07:00: Drilled from 1367,5 m to 1372 m MD with reduced ROP due to problems with cold mud overflowing the shakers.
07:00 - 08:00: Criculated and conditioned mud at reduced rate 2200 LPM due to overflowing on shakers.
08:00 - 08:15: Pulled back into 20" casing without pumping.
08:15 - 10:00: Circulated and conditioned mud with bit inside 20" casing. Changed shaker screens to 145 mesh. Established flowrate of 4500 LPM.
10:00 - 10:15: Lined up cement unit down standpipe and kill line. Flushed lines with mud prior to XLOT. Closed BOP on 5 1/2" DP.
10:15 - 10:45: Performed XLOT. Pressured up 1st cycle at 100 LPM. Did not achieve expected response.
10:45 - 11:00: Verified line up by closing in and releasing 10 bar down drillstring and kill line OK.
11:00 - 12:00: Continued XLOT. Pumped 1000 liter at 100 LPM to get to 8-10 bar, zeroed counter. Pumped an additional 500 liter to 26 bar. Unexpected respons. Bled back pressure.
12:00 - 13:30: Pressured up again with same volume at 200 LPM. Monitored trip tank for leakage above BOP none detected. Repeated cycle twice more up to approx 50 bar at 100/200 LPM. No definitive leak off pressure could be determined. Prepared for work on standpipe valves.
13:30 - 15:45: Dismanteled manual choke valve on standpipe manifold. Greased valve s2, 10 and 11.
15:45 - 17:15: Pressure tested standpipe manifold. Valves s3, 6, 7, 8 and 11 tested OK.
17:15 - 18:45: Lined up pumps and flowline for drilling. Stepped up rate to 4500 LPM. Cycled flowrates 3800/4500 LPM to set powerdrive according to instructions from DD. Fast procedure failed. Reverted to long procedure, powerdrive set OK.
18:45 - 22:30: Drilled 17 1/2" section from 1372 m to 1422 m MD. Inserted and drilled with 1 singel to complete tally. Drilling parameters flow 4500 LPM SPP 235 bar 120 RPM 10 MT wob torque 15-20 KNM.
22:30 - 23:00: Started setting powerdrive for corrections needed according to directional plan. Cycled rate 3800/4500 LPM. Had overload of cuttings conveyer belt which was shut down by safety switch. Had to stop pumping because the cuttings conveyer belt had stopped.
23:00 - 23:30: Worked to clean and re-start cuttings conveyer belt.
23:30 - 00:00: Continued cycling rate at 3800/4500 LPM to set powerdrive. Continued drilling from 1422 m to 1431 m MD.

24-hour summary: Performed XLOT to 1,70 EMW. Drilled 17 1/2" hole from 1369 to 1461 m MD. Serviced standpipe manifold valves. Cleaned cuttings conveyer belt after unintentional stop.
