sum24Hr: POOH with 17 1/2 drilling BHA from TD m to surface. Overpulls up to 10-15 mT mT experienced at 1385 m MD. Worked string past obstructions with flow of 3000 lpm and rotation of 15-50 rpm. Worked area from 1385 m MD to 1357 m MD. Observed peaks of 20 kNm at 1370 m MD and 1381 m MD. Stopped rotation and circulation and pulled from 1385 m MD to 1357 m MD with no overpull. Racked back BHA in derrick due to high winds. Jetted BOP and wellhead. Retrieved nominal seat protector. Rigged up casing running equipment. Ran 13 3/8" casing to 40 m MD. Checked float.

comments: Installed casing tong on IR tracks. Made up DP x-over to 13 3/8" casing swadge. 

Meanwhile lined up cement unit to pump down F-14 injection annulus. Stepped up pressure from 126 bar to 138 bar when sudden leak off to 60 bar was observed. Continued injection and stepped up pump rate to 1000 lpm / CUP 71 bar. Injected 150 m3 seawater at 1000-1200 lpm. After shut in the pressure stabilized at 50 bar after 1 hour (still 50 bar at 07:00).
