comments: Drilled 36" hole section from 145 m to 165 m MD with reduced drilling parameters : Flow 600-1000 lpm / Rotation 10-25 rpm / WOB 1-3 MT / Torque 3-16 kNm. ROV observed that drill guide bushing landed in funnel. Survey at 165 m MD 0,21 deg. High torque and excessive rattling in string from 160-165 m MD.
