Activities:
comments: Drilled 17 1/2" hole from 328 m to 353 m using 5 1/2" HWDP as drilling stand; 4000 lpm, 139 bar, 70 rpm, 2-5 kNm, 1-2 MT WOB. Up weight 102 MT/down weight 100 MT. Pumped 10 m3 hi-vis sweep and spotted 10m3 hi-vis on bottom prior to each WL gyro run. Performed WL gyro surveys at 331m, 339m, and 353 m. Each run taking approx. 1 hr incl. RU and RD.

comments: Drilled 17 1/2" hole from 353 m to 650 m; 4000-4500 lpm, 141-177 bar, 80 rpm, 4-8 kNm, 4-6 MT WOB, ROP 35-70 m/hr. Pumped 3 x 10 m3 hi-vis sweeps and reamed one single pr std. Performed gyro survey every 30 m until more than 15 m away from F-12. Performed gyroMWD survey every std (approx every 40 m) from there on. Slided in following intervals: 480-495m, 530-538m, 560-570m, 595-610m, 632-650m.

Meanwhile inspected TDS and derrick for loose items. Checked die-carriers. Carried out repairs on forward PRS. Pressure tested BOP (6 months tests).
