Hourly activities:
00:00 - 07:30: Layed out 7in TBG from derrick. Pressure tested BOP. Carried out maintenance on both prss. Continued monitoring WH pressure on XT gauge. As pressure increased from 40 bar squeeze pressure) to 60 bar due to temperature effect it was bled off back to 40bar. Had to bleed off several times. Cycled HMV and MMV valves on XT every 1 hour. Meanwhile WOC
07:30 - 08:00: Performed pre-job meeting for pressure testing and inflow testing cement plug and DHSV. Continued monitoring WH pressure on XT gauge.
08:00 - 09:15: Performed line test, rigged up bleed off line from cement unit to closed drain
09:15 - 10:00: Closed HMV and bled off pressure between HMV and swab valve. Opened SV and equalized pressure above HMV according to final pressure on XT gauge of 51bar
10:00 - 10:45: Opened HMV and increased pressure in tubing to 320 bar with SW using cement unit. Closed SV and performed cement plug pressure test to 320 bar/10 min. 763liters pumped from 51bar to 320bar.
10:45 - 13:15: Carried out inflow test of cement plug. Bled down pressure in tubing through bleed valve to closed drain to 30 bar. Monitored pressure for 10 min. Slowly increasing. Bled down pressure in tubing to 20 bar. Monitored pressure for 10 min. Slowly increasing. Bled down pressure in tubing to 10 bar. Monitored pressure. Pressure steadily increased 11 bar/1 hour. Bled off from 21 bar to 10 bar. Monitored pressure for 30 min. Pressure increased 4. 5 bar with clear decreasing trend towards the end. Good inflow test.
13:15 - 16:00: Carried out inflow test of DHSV. Equalized pressure and opened swab valve and applied 310 bar to tubing. 830l pumped. Closed DHSV. Bled off pressure in tubing above DHSV to 240 bar. Checked pressure on DHPG to confirm DHSV is closed. OK. Monitored pressure above DHSV for 30 min for 70bar LP inflow test. Pressure increased 2. 5bar in 30 min with decreasing trend towards the end. Good LP inflow test. Bled down pressure in tubing above DHSV to 10bar. Checked pressure on DHPG to confirm DHSV is closed. OK. Monitored pressure above DHSV for 30 min for 300bar HP inflow test. Pressure increased 2bar in 30 min with decreasing trend towards the end. Good HP inflow test. Equalized pressure above DHSV, pressured up control line to DHSV to 520bar to open DHSV. Bled off tubing pressure
16:00 - 16:15: Performed pre-job meeting for rigging down cement spool.
16:15 - 19:00: Started to rig down cement spool. Observed light fluid flow from KWV side of XT. Evaluated situation and concluded to trap 20bar under DHSV to have a differential across DHSV. Reconnected hose and swivel to cement spool. Confirmed line up. Pressured up tubing to 20bar. Bled off pressure above DHSV to 0 bar. Confirmed with DHPG that DHSV closed. 20bar differential pressure from below. Flow checked the well on KWV. Stable.
19:00 - 20:45: Rigged down cement spool. L/d cement spool in moonpool
20:45 - 21:00: Performed pre-job meeting to instal BPV and XT cap
21:00 - 22:15: Lowered BPV on tugger into XT and landed BPV in tubing hanger. Installed XT cap
22:15 - 23:15: Disconnected hydraulic hoses and lines from XT
23:15 - 23:30: Removed scaffolding on XT deck, meanwhile performed TBT to remove hatches in moonpool
23:30 - 00:00: Removed hatches on f-15 and f-10 in moonpool

24-hour summary: layed out 7in TBG from the derrick pressure tested BOP pressure tested and inflow tested cement plug pressure tested and inflow tested DHSV r/d cement spool installed BPV started n/d XT
