Hourly activities:
00:00 - 00:30: Installed diverter in housing.
00:30 - 02:15: Ran slickjoint and landed same on top of BOP. Removed running slings from bails and installed elevator.
02:15 - 03:30: Function tested BOP shear ram OK. RIH with test plug for testing BOP connection. Function tested BOP rams and annular OK. Landed test plug in surface wellhead. Performed line test and verified line up by opening HCR with 35 bar OK.
03:30 - 04:15: Pressured up to 35 bar using cement unit mismatch pumped vs theoretical volume. Suspected pressuring up against GT plug. Opened b-annulus valves to vent underneath plug and pressure dropped immediatly. Leakage observed across test plug despite steady pressure 35 bar indicating that plug did not vent into pipe when doing pressure test. Discussed situation decided to re-attempt test while keeping b-annulus valves open.
04:15 - 05:15: Increased pumprate to 50 LPM and put 100 bar differential across plug, leakage decreased and pressure curve indicated that plug was sealing. Achieved steady pressure curve at 100 bar. Bled off pressure to 35 bar and held test for 5 mins bar drop 5 min). Steady fluid returns observed from b-annulus. Pressured up to 345 bar and tested connectors inner a annulus valve for 10 min 1,3 bar drop OK. Shifted valves on a annulus. Held pressure and pressure tested outer a annulus valve for 10 min 0,7 bar drop OK. Pumped and bled back 43 liter 345 bar). Still minor fluid returns from b-annulus outlet but gradually decreasing.
05:15 - 05:30: POOH with 5 1/2" DP stand and test plug. Observed dirt/mud residues plug. Found pieces of steel in the mud residues. Strapped pipe and found landing point 20,45 m vs theoretical 20,81 m but likely that plug landed too shallow.
05:30 - 06:00: Made up bowl protector to running tool and made up to stand of 5 1/2" DP. Meanwhile hooked up tension cylinders on BOP.
06:00 - 08:30: Installed bowl protector according to vetco instructions. POOH with 5 1/2" DP stand and laid down RT. Meanwhile hooked up BOP tension cylinerders in moonpool.
08:30 - 09:00: Held toolbox talk prior to retrieving annulus insert.
09:00 - 09:30: Checked equipment prior to RIH.
09:30 - 10:30: Picked up and made up annulus insert j-slot retrieval tool.
10:30 - 10:45: RIH with retrieval tool on 5 1/2" HWDP landing string from surface to 76 m MD.
10:45 - 11:00: M rsk crewchange. Held toolbox talk prior to continuing operation.
11:00 - 12:00: RIH with retrieval tool on 5 1/2" HWDP landing string from 76 m to 120 m MD. Made up TDS and took torque readings wiith annular closed psi on strip bottle). Torque 0,3-0,6 KNM at 5 RPM.
12:00 - 13:30: Tagged annulus insert at 139,68 m MD. Engaged j-slot and confirmed with 1 MT overpull.
13:30 - 14:15: Closed annnular and backed out insert with 3 lefthand turns. MAX torque 5 KNM. Observed for pressure build up none obeserved. Continued backing out annular insert with another 3 lefthand turns observed 6" travel OK.
14:15 - 14:30: Opened annular. Attempted to pull free had 18 MT overpull. Continued rotating left and came free with annular insert.
14:30 - 15:00: Flowchecked well well static.
15:00 - 15:45: Emptied trip tanks. Displaced well to 1,03 SG completion fluid at 1000 LPM. Pumped a total of 26 m3.
15:45 - 16:45: Broke out TDS. POOH with annular insert on 5 1/2" HWDP landing string from 138 m MD to surface.
16:45 - 17:00: Broke out annular insert RT. Worked to free annular insert free from j-slot running tool due to debris jamming the sleeve.
17:00 - 17:15: Held toolbox talk prior to making up smith 10 3/4" spear.
17:15 - 18:15: Made up spear to 5 1/2" HWDP checked serial no OK. Broke spear and inserted 9,632" nominal grapple. Made up spear using rig tongs.
18:15 - 19:45: Made up adjustment sub setting tool to stand of 5 1/2" HWDP checked serial no OK.
19:45 - 21:30: Performed extra washing trip in order to clean tie-back adapter. Made up bullnose/jet sub. RIH on 5 1/2" DP from surface to 140 m MD. Stepped up pumps to 3500 LPM SPP 68 bar. Passed tie-back adapter and pulled back while pumping and rotating with 5 RPM. Pumped a total of 25 m3. Took returns to separate pit. POOH with jet sub.
21:30 - 22:00: Made up bowl protector RT and RIH on stand of 5 1/2" DP to 20 m. Caught bowl portector and POOH.
22:00 - 22:15: Held toolbox talk prior to rig up 10 3/4" casing running equipment.
22:15 - 23:15: Cleared and tidied drillfloor prior to bringing in casing running equipment.
23:15 - 00:00: Installed BX-3 elevator, changed inserts and function tested same.

24-hour summary: Installed bowl protector. Retrieved annulus insert in 10 3/4" hanger. Displaced well to 1,03 SG packer fluid. Made extra washing run to clean tie-back adapter. Retrieved bowl protector. Rig up for running 10 3/4" tie-back casing.
