Activities:
comments: Drilled 12 1/4" hole from 3212 m to 3280 m; 3500 lpm, 227 - 230 bar, WOB 6 - 14 tons, 170 rpm, 18 - 30 kNm, ECD 1.34 - 1.35 sg. ROP 30-40 m/hr
Note: Hard stringers from 3227 m to 3229 m, 3262 m to 3280 m. Used different RPM and WOB parameters while drilling stringers. ROP in stringers: 2-5 m/ hrs.
