comments: Drilled 8 1/2" hole from 3059 m to 3142 m in Shetland with 1.32 sg OBM. Drilling parameters : 2150 lpm / SPP 145 bar / 160 RPM / torque 15-19 kNm / WOB 11-15 MT / ECD 1.35 sg EMW / ROP 2-5 m/hr. 

Meanwhile started to MU and RB stands of 10 3/4" csg in derrick.

A 10 3/4" csg double slided out of grip when aft PRS was transfering/lifting casing out of double latch at set back. The 10 3/4" csg double fell on to TDS blower hose.

comments: Evaluated situation. Made SJA and held tool box talk for recovering 10 3/4" csg double. Secured lower end of csg and attached pick up elevator on top end.

Meanwhile circulated 8 1/2" hole at minimum rate. Parameters : 1100 lpm / SPP 42 bar / 60 RPM / torque 10-12 kNm. Stopped rotation when man-riding to attach pick up elevator.

comments: Drilled 8 1/2" hole from 3142 m to 3180 m in Shetland with 1.32 sg OBM. Drilling parameters : 2150 lpm / SPP 146 bar / 160-200 RPM / torque 14-18 kNm / WOB 9-12 MT / ECD 1.34-1.35 sg EMW / ROP 2-9 m/hr. Stopped pumps to reset BHA tools. Not able to build angle/no response from Xceed. Decided to POOH to change BHA.
