Activities:
comments: Closed DHSV and bled off above to 5 bar above. 120 ltrs bled back indicating DHSV not closed. Opened DHSV and pressured up and equalized above to 50 bar. 120 ltrs pumped. Observed drop in pressure on BOT pump indicating DHSV open, but had only 280 ml bled back.  Repeated sequenze 2 more times before we got good indication that DHSV was fully open and had 220 ltrs bled back.

Repeated function test of DHSV. Closed DHSV and bled off above to 5 bar. 80 ltrs bled back. Observed for 10 min to confirm that DHSV was fully closed and not leaking. Ok. Opened DHSV and pressured up and equalized above to 50 bar. 80 ltrs pumped. Observed drop in pressure on BOT pump indicating DHSV open. Bled off pressure down to 5 bar. 220 ltrs bled back.

comments: Pressured up tubing from 5 bar to 380 bar. 1386 ltrs pumped. Kept 570 bar on DHSV CL. Held pressure for 15 min to set packer and test tubing. Ok. Had 1.3 bar drop. 

Observed load vibration noise on rig floor when pressure reached 260 bar. Investigated TH and all well head levels. No findings.

Bled off tubing pressure and observed pressure dropped immediately to zero. Concluded that lead target blocked cmt line. This was in accordance with observed noise. Bled off tubing pressure carefully to zero. Had 1360 ltrs bled back.

comments: Pressured up tubing to 330 bar while keeping 570 bar on DHSV CL. 1157 ltrs pumped. Closed DHSV and bled off pressure above DHSV to 260 bar. 20 ltrs bled off. Inflow tested DHSV to 70 bar diff/15 min. Had 1.3 bar drop.

Bled off pressure above DHSV to 10 bar. 140 ltrs bled back. Inflow tested DHSV to 320 bar diff / 30 min. Had 0.1 bar increase. Equalized pressure by pressuring up to 330 bar above DHSV and opened DHSV. 220 ltrs pumped. Bled off pressure in tubing to zero and kept DHSV open with 570 bar. 1000 ltrs bled back.

comments: Pressured up A-annulus to leak test packer from below and TH from below to 35/380 bar for 5/10 min pumping brine at 70 lpm. Kept tubing open on drill floor and 570 bar on TRSCSSV CL. Pumped 117 ltrs and observed 0.01 bar drop on low pressure test. Pumped 1170 ltrs (total) and observed 0.5 bar drop on high pressure test. Had flow on both tubing and B-annulus while pressuring up A-annulus due to ballooning effect. No flow observed when pumps was shut in. Bled pressure down to zero and had 1100 ltrs in return. Bled off and shut in A and B-annulus. Closed TRSCSSV. Had leak in FWD PRS.
