sum24Hr: Drilled 12 1/4" hole section from 1653 m to 1895 m MD and sorted out problems with mill pump and slurry system. RECORDED ON F-99: Circulated hole clean, flow checked and POOH with 12 1/4" BHA from 1884 m to inside 13 3/8" csg shoe at 1381 m due to exhaust fumes on drill floor. Circulated inside 13 3/8" csg shoe to keep MWD batteries alive.

Activities:
comments: Drilled 12 1/4" hole section from 1522 m to 1653 m MD. Drilling parameters : Flow 3300-3500 lpm / SPP 159-179 bar / String RPM 120 / WOB 2-4 MT / Torque 13-17 kNm / ECD 1.37-1.38 sg EMW / Drilled with limited ROP 20-40 m/hr due to problems transfering slurry from milling tank through active tank to holding tank.  

Meanwhile MU and RB 9 5/8" csg. stds. A total of 14 stds 9 5/8" csg RB in derrick.

comments: Drilled 12 1/4" hole section from 1672 m to 1793 m MD. Drilling parameters : Flow 3500 lpm / SPP 172-174 bar / String RPM 120-150 / WOB 3-4 MT / Torque 12-19 kNm / ECD 1.37-1.38 sg EMW. Unable to drill on because holding tank was full (unable to inject slurry because it did not meet viscosity requirement) and cuttings screw going to skip clogged up.
