Hourly activities:
00:00 - 01:45: Evaluated situation. Discussed situation w/ onshore organisation, callled well integrity duty meanwhile prepared papers and serviced/drops checked rig floor equipment
01:45 - 03:30: Continued discussing way forward. Discussed risks, barrier status, well control contingencies. Agreed to attempt to pull tubing hanger with 152bar trapped pressure below DHSV. Updated change log. Meanwhile applied 20 bar to tubing and inflow tested DHSV, good. Continued with rig maintenance and pressure tested valves s1 and c26, good
03:30 - 03:45: Performed pre-job meeting for pulling tubing hanger as per agreed new plan
03:45 - 04:30: R/d cementing hose, chiksans. Attempted to back off weco1502 swedge. Collar backing off together with swedge. Torqued up collar to 15000 ft lbs and manage to break off swedge, l/d same
04:30 - 05:30: Installed circulating swedge for TDS. M/u TDS and unlock tubing hanger. Pull tubing hanger free with 185t hook load overpull). Observed drop in trip tank indicating that a-annulus was not 100 full. Waited for trip tank level to stabilize, total of 2 m3 lost
05:30 - 07:00: Continued to pull landing string to th. After pulling further 9m, observed gain in trip tank indicating seals pulled out of PBR. Stopped and flowchecked, after 270l gain trip tank static. Gain volume corresponded to expected volume value due to trapped pressure below DHSV
07:00 - 07:15: Performed pre-job meeting to l/d THRT and to POOH 7in tubing w/ control lines
07:15 - 08:00: Cut control lines. L/d th and THRT 2 pup joints from 2976m to 2962m
08:00 - 08:45: Connected control lines to reel. Removed master bushing and installed compact spider slips. Pull 1x joint while doing adjustment on slips and tong
08:45 - 10:30: Pull 7in tubing from liner 2951m to 2737m. Measured radioactivity every 10 joints. Average pulling speed 6,8joints/hour
10:30 - 10:45: Performed time out for safety w/ crew due to radioactivity recorded in 7in tubing. 10-16 bq/cm2 and 1-2usv/h recorded
10:45 - 12:45: Continued to pull 7in tubing from 2737 to 2473m. DHSV assy in rotary. Average pulling speed 10joints/hour continued to measure radioactivity at 9-12 bq/cm2 and 1-2usv/h on inside of tubing and 3-4 bq/cm2 and 0. 5usv/h on the outside of the tubing
12:45 - 13:15: R/d compact spider, install master bushing
13:15 - 13:30: P/u 1x joint and cut control line to avoid having control line across BOP during WL operation. RIH w/ same and l/d DHSV
13:30 - 14:15: Lifted WL equipment and tool string to rig floor. Meanwhile cleaned and cleared rig floor
14:15 - 14:30: Performed pre-job meeting to r/u WL equipment
14:30 - 16:30: R/u for WL and m/u logging tool string Performed surface check prior to RIH
16:30 - 18:15: RIH with logging BHA on WL. From surface to 2960m. Checked pick up weights every 500m. Average running speed 28m/min
18:15 - 20:45: Logged USIT across interval 2960 2506 m. Performed repeat pass across interval 2960 2860 m. Processed and uploaded data into interact system. Confirmed quality of data with logging duty. Received confirmation from logging duty that following intervals had high cement quality 2895-2960m, 2660-2671m
20:45 - 21:45: POOH from 2500 m to surface. Average pulling speed 42 m/min.
21:45 - 22:30: R/d WL equipment and change elevator inserts to 5,5in DP. Meanwhile function tested DHSV on deck. Observed indication of sleeve moving and flapper openning/closing
22:30 - 22:45: Performed pre-job meeting to r/d tubing tong
22:45 - 00:00: R/d tubing tong

24-hour summary: pulled th to surface pulled 500m of tubing and l/d DHSV RIH and performed CBL log r/d WL
