comments: Held toolbox talk prior to setting MS seal. Pressured up to 207 bar with cement unit through kill line for 10 mins to set the MS seal. Volume pumped 272 liters.

comments: Closed shear ram and lined up to pressure up underneath with cement unit. Pressured up with cement unit to 345 bar. Pumped a total of 2630 liter on 1st attempt, good correlation with theoretical volume. Observed trendline which did not stabilize - steady drop observed at around 1 bar/min. Pressured up twice to 345 bar - same trend observed. Total volume pumped 2860 liters Attempted to bleed pressure back to cement unit - nogo, kill line blocked for unknown reason. Bled back to trip tank and recovered 2500 liters. Decided to re-attempt pressure test up cement line.

comments: Troubleshot leakage in well. Pressured up on well to 345 bar from cement unit through cement line. Similar trendline observed with leakage rate of 0,5-1 bar/min. Pressured up on well twice more. Bled off pressure rapidly and lined back to cement unit. Pressure on cement unit rose from 2,8 bar to 7 bar over 2 hrs. Meanwhile discussed situation and way forward. Prepared for running MS seal retrieval tool.

comments: Picked up MS seal retirevel tool and inspected seals. RIH with retrieval tool on 5 1/2" HWDP landing string as per Vetco procedure. Engaged tool by 1/2" turn lefthand. Set down landing string weight of 10 MT instead of the intended 3 MT. Adjusted string weight and string jumped approx 0,3 m, got sudden gain in trip tank of approx 250 liter. Closed annular and pulled MS seal free with 10 MT overpull. POOH with retireval tool and MS seal on 5 1/2" HWDP. Backed off MS seal, re-set running tool and laid down same.
