comments: POOH with 13 3/8" P110 72# casing from 2579 m to 2538 m MD on 5 1/2" HWDP while circulating at 400 lpm / 5 bar. Observed rapid pressure increase to 35 bar and shut off pump at 2538 m.

Meanwhile changed head on PDM.

comments: Attempted to free 13 3/8" csg by working string down, but pressure did not bleed off.  Worked string with 35 MT upwards and 45 MT downwards. Pressure dropped off while working pipe upwards.  Pumped 100 lpm while working pipe upwards (pressure increase when stopped pumping) and regained circulation at 2504 m. Staged up pumps to 2300 lpm / 27 bar.
