00:15 - 02:15: Attempted to install 10" diverter elements, not possible due to damaged elements. Changed master bushing for PS 21 slips.
02:15 - 04:45: Continued RIH with 12 ¼" drilling BHA on 5½" DP to 859 m, made up to TDS, established circulation, washed down from 859 m with 1180 LPM 30 RPM. Tagged TOC at 880 m.
04:45 - 06:00: Drilled cement/float from 880 m to 881 m with sea water 3060 LPM, 70 RPM and 84 bars.
06:00 - 11:00: Continued drill out shoe track from 881 m to 898 m, 3200 LPM, 99 bars, 70 RPM, 3-6 KNM, 2-3 MT wob, pumped 20 m hi-vis at 898 m.
11:00 - 11:30: Took out the PS-21 slips and installed the 10" diverter inserts, re-installed the PS-21 slips.
11:30 - 13:15: Continued drill out shoe track from 898 m to 908 m 13 3/8" shoe. Drilled out rat hole from 908. M to 916. 5 m, 3200. LPM, 100 bars, 70 RPM, 4 KNM, 1 MT wob.
13:15 - 14:00: Cleaned rat hole. Held tool box talk prior to displace hole to WBM.
14:00 - 15:30: Displaced well to 1. 28 SG soludril-n WBM, 3200 LPM, 90 120 bars SSP. Density of mud in returns 1,26 SG.
15:30 - 17:30: Continued to drill ahead from 916. 5 to 959 m. 3200 LPM, 90 120 bars, wob 1-10 MT, 70-180 RPM, torque 3-20 KNM. ECD 1. 29 SG EMW. MP-1 shut down.
17:30 - 18:00: Pulled off bottom circulating with MP-2, 1700 LPM, 42 bars SSP. MP-1 was re-started, the shut down caused by electrical error.
18:00 - 18:15: Continued to drill ahead to 970 m, stand pipe pressure dropped 40 bars.
18:15 - 19:00: Trouble shooted stand pipe pressure drop, tested/ checked MP-1 and MP-2, found no indication of surface error. Stand pipe pressure back to normal.
