comments: Continued drilling 8 1/2" hole section from 3103 m to 3265 m MD. Added LCM materials to mud prior to entering reservoir. Drilling parameters : Flow 2200 lpm / SPP 220-231 bar / String RPM 180 / WOB 3-8 MT / Torque 11-20 kNm / ECD 1,61-1,62 sg. ROP 10-30 m/hrs. Observed top of Hugin reservoir on logs 3250 m MD / 2987 m TVD. Max gas at top reservoir lag depth 5 %.

Performed pit drill at 16:25 hrs. Good response from loggers and driller.
