Activities:
comments: Drilled 17 1/2" section from 314 m to 475 m MD. Drilling parameters : Flow 3200-4000 lpm / SPP 74-160 bar / WOB 3-8 MT / Torque 2-5 kNm / String RPM 40 / Bit RPM 136-160. ROP 40-65 m/hr, average ROP 26.8 m/ hrs. Pumped 10 m3 hi-vis sweep for every singel drilled. Performed gMWD survey on connections. Used sling and tugger on centralizer deck on drillpipe to stabilize same before taking survey.

Sliding intervals: 314 - 328 m
                           355 - 380 m
                           395 - 407 m

comments: Drilled 17 1/2" section from 475 m to 556 m MD. Drilling parameters : Flow 4000 lpm / SPP 114 bar / WOB 3-4 MT / Torque 2-5 kNm / String RPM 40 / Bit RPM 136-160. ROP +/-35 m/hr, average ROP 18.0 m/ hrs. Pumped 10 m3 hi-vis sweep for every single drilled. Performed gMWD survey on connections. Used sling and tugger on centralizer deck on drillpipe to stabilize same before taking survey. Up weight 112 MT / down weight 107 MT.

At 556 m made 3 attempts to take gMWD survey. Decided to drill on with MWD inc and azimuth. 

Sliding intervals: 475 - 487 m
                           516 - 529 m
