comments: Continued drilling 8 1/2" hole section from 3302 m to 3327 m MD. Drilling parameters : Flow 2100-2200 lpm / SPP 216-238 bar / String RPM 180 / WOB 3-8 MT / Torque 11-20 kNm / ECD 1,61-1,63 sg. Limited ROP to and cut back flowrate to 2100 lpm due to increasing ECD. Downlinked powerdrive to stop build. Got problems with mudpump#2 and mudpump#3.
