Activities:
comments: Drilled and oriented 17 1/2" hole from 1467 m to 1478 m MD. Obtained first good survey at 1478 m MD. Drilling parameters : 4500 lpm / SPP 228 bar / 3 MT WOB / 80-100 RPM / Torque 10 kNm / ECD 1,43-1,44. Attempted to increase ROP to 20 m/hrs, resulted in blockaged in cuttings injection system (active tank). Dercreased ROP to 15 m/hrs as dictated by cuttings handling. Downlinked powerdrive according to DD instructions.

comments: Drilled and oriented 17 1/2" hole from 1608 m to 1635 m MD. Got problems with cuttings handling. Mill loop on active tank got blocked. Worked to unblock line. Meanwhile continued drilling at lower ROP and routed cuttings to skips as required. Drilling parameters : 4000 lpm / SPP 195 bar / 2-3 MT WOB / 130 RPM / torque 8-10 kNm / ECD 1,44. Controlled ROP to 5-10 m/hrs as dictated by cuttings handling and toubleshoting.
