comments: Halted drilling due to all cutting skips full. Pulled off btm. Circulated and reamed from 1796 m to 1760 m with 3560 lpm / SPP 171 bar / 80 rpm / torque 7 k Nm while waiting for boat.

Attempted to prepare content of slurry holding tank for injection, but were unable to get fluid within viscosity spec. 

Boat arrived location at 16:15. Transfered content of slurry holding tank to boat from 17:50 to 19:45.
