comments: Drilled 8 1/2" hole from 3059 m to 3142 m in Shetland with 1.32 sg OBM. Drilling parameters : 2100-2150 lpm / SPP 144-152 bar / 150 RPM / torque 16-20 kNm / WOB 8-15 MT / ECD 1.37 sg EMW / ROP 5-30 m/hr.

Meanwhile prepared for MU and RB 10 3/4" csg. Had to use emergency stop on HTS to stop 10 3/4" csg joint which was moved too far forward and tilted onto drill flor. Investigated problem and recalibrated HTS joy stick.
