Activities:
comments: Took 15 MT weight at 3392 m MD. MU TDS and attempted to work past tight spot with 20-30 MT. Up weight 181 MT / down weight 141 MT. Applied 9400 Nm RH torque when working string up. Released torque when working down.

comments: Broke circulation, 230 lpm / 37 bar and established rate at 530 lpm / 49 bar. Washed down to tight spot applying max 20 MT. Observed pressure increasing to 60 bar. Shut down pumpe. Recorded 22 bar back pressure trapped below shoe. Applied 9400 Nm RH torque and worked string up. Recorded up weight of 151 MT, 30 MT upweight less than previous. Liner hanger RT most likely released from 7" liner.

comments: PU and established up weight at 151 MT. Slacked off weight at 130 MT and observed no drag. Unable to tag liner. Broke circulation 220 lpm / 22 bar which indicated that we were circulating through 5 1/2" DP and liner hanger RT. 7" liner most likely dropped further down.
