Meanwhile inspected AFT PRS and found damage on drag chain. Barried off rig floor.

comments: Pressured up to 35 bar on B-annulus. Pressured up to 175 bar with MP2 using packer fluid on csg side. Observed 17 bar pressure increase on B-annulus due to ballooning (35-52 bar)

Attempted to pressure up B-annulus to 220 bar with cmt unit. Stopped pumping at 97 bar and only 16 ltrs pumped (theoretical volume to 97 bar = 280 ltr).

comments: Bled off B-annulus and csg to 0 bar and investigated surface lines. Disconnected 5K hose from cmt unit to surface wellhead and flushed through to verify no restrictions. Reconnected 5K hose to B-annulus and performed new line test 30/225 bar 5/10 min against closed outer valve on wellhead outlet. Pressured up to 50 bar on B-annulus with only 23 ltr pumped (23 ltr corresponds to pressuring up volume down to subsea wellhead, indicating blockage in 10 3/4" hanger annulus ports).

comments: Held tool box talk for testing 10 3/4" x 14" annulus. Performed line test to 20 bar to verify correct line up for both BOP kill line and B-annulus. 

Pressured up csg with MP2 to 50 bar/400 ltrs - Recorded 10 bar on B-annulus from cement unit.
Pressured up csg with MP2 to 70 bar/155 ltrs - Recorded 12,4 bar on B-annulus from cement unit. 
Pressured up csg with MP2 to 156 bar/644 ltrs - Recorded 21 bar on B-annulus from cement unit.

Observed leak into B-annulus at 156 bar, confirming communication through annulus ports in 10 3/4" hanger from below (recorded pressure increase above ballooning effect). Recorded 1,9 bar/10min pressure increase on B-annulus with 135 bar differential pressure.

comments: Had time-out to evaluate further action. Made arrangements for punching holes in 9 5/8" csg.

Meanwhile logged pressure on csg and B-annulus. Recorded 0,25 bar/10min pressure increase on B-annulus with 56 bar differential pressure.

comments: Waited for tubing puncher equipment and schlumberger personnel to arrive on the rig. 

Bled off pressure on B-annulus from 60 to 2 bar in preparation to test shear rams. Observed pressure on csg driopping from 116 bar to 106.4 bar while bleeding off on B-annulus (due to balloning effect).

RIH with WBRT and pulled WB. RIH with 2 stds of 5" DP and test plug to 100 m MD. Sat test plug.
