comments: Pulled bit inside casing shoe at 1350 m MD. Lined up for FIT test to pump down pipe and annulus. Closed annular. Pressured up to 7 bar to fill standpipe and kill line and observed rapid increase in pressure / curve deflection. Pumped 121 liter up to 17 bar. Pressure fell to 13 bar over 15 min, steady leakage rate. Bled back 50 liter.
