comments: Pumped 10 m3 hi-vis pill and started drilling 8 1/2" pilot hole from 890 m to 941 m2250 lpm/105 bar, 120 rpm/1-3 kNm, 0-1 MT wob, ECD 1.12 - 1.20 SG . Pumped 10 m3 hi-vi pills according to program. Had to back-ream 1 std every 5-10 m due to high ECD readings. Meanwhile decided to displace well to WBM.
