06:00 - 07:30: Finished slipping and cutting drilling line time due to recent high winds having fouled hangoff lines in derrick).
07:30 - 12:00: Finished POOH. Changed saver sub on TDS.
12:00 - 17:30: Made up jet sub, 3 stands HWDP, BOP test tool, and RIH. Jetted wellhead MAX gas). Tested BOP on blue pod from drill floor rams, failsafes, and lap to 35/345 bar for 5/10 minutes, uap to 35/241 bar for 5/10 minutes. Function tested BOP from tp office on yellow pod. Tested acoustic system. POOH with test tool and l/d tool and jet sub.
17:30 - 22:00: Made up bit to motor. Dumped memory and changed out MWD'S. Set ako at 1. 2 deg. And checked alignment with MWD. Finished RIH with BHA.
22:00 - 00:00: RIH on drill pipe. Broke circulation every 500 m.

24-hour summary: Slipped and cut drilling line. Finished POOH. Tested BOP. RIH with drilling BHA. Began washing to bottom from 2600 m.
Hourly activities:
