sum24Hr: Worked NPR pulling string to be able to pass production PBR at 2972 m. Attempted to change seal stem position in sheared PBR by applying 100/200 bar on annulus. No sucess. Performed 35/345 bar 10 min pressure test of tubing and production packer from below. Worked NPR pulling string with 345 bar on tubing to change seal stem position in PBR. No sucess. RIH to TCP gun hanger at 3089 m and freed GS pulling tool from NPR plug. POOH and LD GS pulling tool.

comments: Pressured up tubing to 10 bar with cement unit. Volume pumped was 40 ltrs. RIH and latched plug at 3014.8 m MDRKB. Observed for pressure drop for 15 min when equalizing the plug. No pressure drop observed. Jared plug free and waited for 30 min to let plug elements retract. Confirmed that plug was free. No pressure drop observed.

comments: POOH with NPR plug from 3014.8 m to PBR at 2972 m. Made attempt to pass PBR with max overpull of 785 kg. Bled off pressure in tubing to zero and waited another 30 min to ensure that elements was released. Bled back 80 ltrs. No returns on A-annulus. Continued to attempt to pass PBR. Max overpull 900kg. Unable to pass restriction at 2972 m MDRKB, but free to go down.

comments: Worked to free NPR pulling string from 3020 m to 2972 m. PU weight was 950 kg. 

Filled tubing up to neddle valve on lubricator and checked for swabbing effect.

comments: Closed A-annulus valve. Moved hose from A to B-annulus. Pressured up to 200 bar to equalize pressure against B-annulus. Opened B-annulus valve and bled off pressure to zero. Bled back 1390 ltrs. Closed B-annulus.

Menwhile adjusted TRSCSSV CL pressure and RU overboard line to A-annulus.
