Activities:
comments: Drilled 12 1/4" hole section from 1886 m to 1895 m MD. Drilling parameters : Flow 3500 lpm / SPP 184 bar / String RPM 150 / WOB 2-3 MT / Torque 14-20 kNm / ECD 1.37 sg EMW. Drilled with limited ROP 20 m/hr to observe proper operation of mill pump and slurry system. Stopped drilling due to exhaust fumes on drillfloor. RU cascade system on drill floor.

Meanwhile shut down csg. equipment. A total of 29 stds 9 5/8" csg RB in derrick.
