500 lpm/36 bar, choke 13 bar.
600 lpm/43 bar, choke 12 bar.
700 lpm/49 bar, choke 10 bar.
800 lpm/58 bar, choke 9 bar.
while circulating at 800 lpm and attempt to maintain 58 bar on drill pipe. After approximately 300 strokes the drill pipe pressure increased to 70 bar, at same time casing pressure dropped to 2 bar. Close choke. Attempt to trap 15 bar on casing, pumped in 1 m3 and shut down pump after no pressure increase observed. Shut down pumps and casing pressure increased to 14 bar. SIDPP 30 bar. Choke pressure dropped to 7 bar. Started pumping again, 5 spm, pressure increased, casing pressure to 28 bar, choke 15 bar.</witsml:comments>

<witsml:comments>PJSM held prior to circulating bottoms up through the choke. Establish circulation at 5 spm. Step up rate slowly to 800 lpm. Decrease annular closing pressure and rotate pipe every 30 min while circulating to confirm that pipe was free. Rotate with 6 RPM, 33-37 kNm of torque.
Observed max gas of 3,2% gas at bottoms up. No cut in mud weight from gas.</witsml:comments>
