04:45 - 06:00: Pulled of bottom started circulating hole clean reciprocating the string. Zero RPM pulling up and 80 RPM working down, pump rate to 1850 LPM SPP 180 bars ECD 1,42 EMW. Average losses 0. 5m
06:00 - 08:15: Continued circulating hole clean reciprocating the string. Zero RPM pulling up and 80 RPM working down, pump rate to 1850 LPM SPP 180 bars ECD 1,42 EMW. 1. 8m gain.
08:15 - 08:30: Monitored well on trip tank, 9. 3m gain, shut well in when the flow was at a rate of 8. 4m
08:30 - 10:45: Closed upper pipe rams, line up to FWD choke. Monitored pressure increase on FWD choke, up to 5. 2bars. Opened choke and bled off approx 0,20m Closed choke and monitored pressure increase on FWD choke, up to 4. 8bars. Opened choke and bled off approx 0,29m Closed choke and monitored pressure increase on FWD choke, up to 4bars. Opened choke and bled off monitoring returns through sample line, flow decreased from 20l/min to 10l/min. Flushed kill and choke lines, opened upper pipe rams.
10:45 - 11:15: Flow checked well static.
11:15 - 13:00: Dropped gyro and pumped down same at 780 LPM.
13:00 - 13:30: Performed gyro rotation shots at 4087m.
13:30 - 17:15: Pumped out of hole from 4087m to 3256m, 20m/min, 730lpm. Due to gyro, pipe to be stationary in slips for 2 min. Before continue POOH.
17:15 - 17:30: Performed gyro rotation shots at 3256m.
17:30 - 19:00: Pumped out of hole from 3256m to 2932m, 20m/min, 730lpm. Due to gyro, pipe to be stationary in slips for 2 min. Before continue POOH.
19:00 - 20:15: Continued pump out of hole from 3932m to 2695m, 20m/min, 730lpm. Due to gyro, pipe to be stationary in slips for 2 min. Before continue POOH.
20:15 - 20:30: Performed gyro rotation shots at 2695m.
20:30 - 21:45: Continued pump out of hole from 2695m to 2531m, 20m/min, 730lpm. Due to gyro, pipe to be stationary in slips for 2 min. Before continue POOH.
21:45 - 22:15: Circulated at shoe. Checked gas levels OK. No excessive gas reading from BTM up. Meanwhile service TDS.
22:15 - 22:45: Flow checked well on trip tank. Well static.
22:45 - 23:15: Pumped 5 m of 1. 62 SG slug. Allowed to settle.
23:15 - 00:00: POOH on elevators from 2531m to 2251m. N. B. Restricted pulling speed to allow hole to take correct volume and gyro restrictions. Due to gyro, pipe to be stationary in slips for 2 min. Before continued POOH. Tripping speed 373 m/hr.

24-hour summary: Circulated hole clean. Dropped gyro. POOH pumping from 4087m to shoe at 2531m. Pumped slug and POOH from 2531m to 706m. Perform gyro rotation shots every 500m. Problems with PS-21 slips.
