Activities:
comments: Drilled 26" section from 350 m to 525 m MD. 
Drilling parameters :
Flow 4000 lpm / SPP 112-116 bar / WOB 4-8 MT / Torque 1-10kNm / String RPM 40 / Bit RPM 160. ROP 26-46 m/hr. Average ROP 29 m/hr.  Pumped 10 m3 hi-vis sweep for every single drilled. Used sling and tugger on centralizer deck on drillpipe to stabilize same before taking survey. At 500m stopped using slings prior to take survey.

Sliding from 349 m to 378 m
                      398 m to 407 m
                      438 m to 447 m

Parallel activity: Tested drilling BOP. Removed wire line unit from rig floor as good MWD survey.
