Activities:
comments: Contined drilling 12¼" hole section from 1979 m to 2145 m MD. Drilling parameters : Flow 3500 lpm / SPP 180 bar / String RPM 150 / WOB 2-11 MT / Torque 10-22 kNm / ECD 1.37-1.395 sg EMW / ROP 30-45 m/hour.
At 2000m started to increase the mud weigth. Took survey after every connection.

Simultaneously MU and RB 9 5/8" csg. stds. Total in derrick 36 stds.

comments: BHA torqued up and stalled out. Released torque and pulled with 50 MT overpull. Attempted to free pipe by rotation. No indication that hole had packed off. Had full circulation. Fired jars two times and came free. Established rotation at full circulation 3500 lpm, to circulate clean the BHA. Experienced sticky tendencies when going down to 2402m.
