comments: Drilled 12 1/4" hole section with limited ROP from 2227 m MD to 2320 m MD. Parameters : Flow 4000 lpm / SPP 233-237 bar / 140 rpm / torque 12-17 k Nm / WOB 3-4 MT / ECD 1,47 / ROP 18-23 m/hr. Downlinked powerdrive according to Schlumberger procedure.

Reduced ROP due to lack off cuttings skips and the time-consuming job to get content of holding tank within spec and ready for injection. 

6 skips arrived with boat at 04:00. Performed preflush and prepared for kuttings injection while taking cuttings return to skips.
