Activities:
comments: Continued to drill 8½" hole from 3500m to 3580m. Drilling parameters: Flow 2100 lpm / SPP 205-209 bars / String RPM 180 / WOB 3-6 MT / TQ 26-28 kNm / ROP 30-50 m/hour / ECD 1.582-1.604 SG / MUD weight 1.45 SG.
Took survey after every connection. Down linked tool.
Held tool box talk as drilling ahead prior taking pressure points.
Parallel operation: Made up 7" liner in stands and racked back in derrick.
