comments: RB 1 std from 3510 m to 3478 m. No obstruction encountered.

Worked 1 std from 3478 m to 3437 m, 2200 lpm / 201 bar, 150 rpm / 12-15 kNm.

RB and reamed 1 std from 3437 m to 3397 m. Observed tight spots at 3428 m and 3423 m. Reamed through tigh spots with reduced flow of 1500 lpm due to packing off. Staged up parameteres to 2200 lpm / 200 bar while working through tight spots.

RB 1 std and circulated btms up whilst rotation and reciprocating pipe from 3397 m to 3357 m, 2200 lpm / 198 bar, 100 rpm / 12-14 kNm.
