Activities:
comments: Drilled and oriented 17 1/2" hole from 2047 m MD to 2084 m MD. Drilling parameters : 4500 lpm / SPP 261 bar / 2-3 MT WOB / 140 RPM / Torque 9-13 kNm / ECD 1,45. Controlled ROP to 20 m/hrs due to cuttings handling. Performed MWD survey on connections. Downlinked powerdrive according to DD instructions. Experienced problems when picking up 5 1/2" stand. Meanwhile made up 13 3/8" casing stands in foxhole.

comments: When attempting to pick up a stand of 5 1/2" DP, the stand was bent. Probable cause is that the stand was caught by the wind and/or hit by the flush joint elevator when making the grip with the gripper head. Hence the stand was bent when retracting the arm. Closed additional fingers to secure the stand in the finger slot. Set down stand and made new grip. Inspected stand visually, stand seemed to by straight and undamaged. Meanwhile reciprocated stand with 3000 lpm / 80 RPM.
