Activities:
comments: Drilled and oriented 8 1/2" hole from 3376 m MD to 3561m MD with 2290 liter/min, 181-185 bar, 180 rpm, 16-19 kNm, WOB 2-7 MT, 1.39-1,45 sg ECD.
Average ROP: 18 m/hr.

At 3380 meter commenced weighing up mud system from 1,28 sg to 1,32 sg.
At 05:00 hrs. restricted ROP to 15 meter/hr due to increase in ECD.
Top Hugin formation at 3561 meter.
