Activities:
comments: Prepared for connection at 941 m and had 10 MT WOB at 934 m, 120 rpm. Slowed down to 30 rpm and re-ran in and got 5 MT WOB at 934 m (had 0-1 MT WOB while drilling this section). Pulled back to 910 m and circulated and swept 2 x 5m3 hi-vis pills. Took time-out to discuss further action. Meanwhile had boat delivering drillwater for mixing mud.

comments: Drilled 8 1/2" pilot hole from 941 m to 1178 m, 2250 lpm/111 bar, 120 rpm/1-5 kNm, 1-2 MT wob, ECD 1.14-1.20 SG. Reamed each stand. Took weight at 978 m, 1027 m, 1040 m and 1060 m, while reaming. Worked through tight spots and continued drilling. Observed max gas  reading of 0.6%. Stringer at 1002-1003 m.
