sum24Hr: Drilled 12 1/4" hole section from 1706 m to 1750 m with reduced ROP due to problems with handling oilbased cuttings. Picked off bottom due to problems with cutting shute blocking. Circulated hole clean at 1730 m. POOH and into csg shoe at 1340 m due to Siemens software upload. RIH from 1340 m to 1750 m. Drilled 12 1/4" hole section from 1750 m to 1787 m MD.

comments: Drilled 12 1/4" section from 1640,5 m  to 1706 m MD. Drilling parameters : Flow 3500 lpm /  SPP 180 bar / 130-170 RPM / WOB 0-2 MT / Torque 10-12 kNm / ECD 1,42. Average ROP 12 m/hrs. Drilled with reduced ROP when going directly to skips. Worked to bring down vicosity in DCI milltank/active before injecting slurry.

comments: Waiting on Siemens software update. Meanwhile: 

- Flow checked well before POOH (static).
- POOH from 1750 m to 1530 m. Up weight 140 MT / Down weight 124 MT. Monitored well on trip tank at 1530 m. Ok.
- POOH from 1530 to inside csg shoe at 1340 m MD.
- Continued with PMs and housekeeping/cleaning.
- Continued injecting cuttings into F-12 and flushed with 2 x annulus volumes of water.
- Repaired Barite hopper B.
