Activities:
comments: Continued drilling 36" hole section from 157 m to 170 m MD. Drilling parameters : Rotation 70 rpm / WOB 2 MT / Flow 4100 lpm / Torque 6-12 kNm . Performed survey on every single - got unreliable data at 157 m and 170 m MD.

comments: Due to unreliable survey data and suspected inclination build up => Performed reaming trip back to 150 m MD.

Meanwhile discussed situation. Found out that surveys had been taken while string was rotating which again gave wrong / unreliable readings.
