Hourly activities:
00:00 - 01:15: Continued troubleshoot loss off pressure. Narrowed causes to a open needle valve on surface wellhead. Closed needle valve.
01:15 - 01:45: Lined rig pumps down string and pumped drill water to above diverter packer and closed same.
01:45 - 02:45: Lined up cement unit to drill string. Pressured up well to 11 bar reference pressure. Pressured up to 34 bar using 101 litre. Pressure dropped and stabilized at 24 bar. Re-pressurized well to 34 bar using 34 litres 3 times while checking valves, diverter packer and well head for leaks. Pressure dropped and stabilized at 24 bar at every attempt.
02:45 - 03:00: Discussed situation with onshore duty. Meanwhile continued to check for possible leaking valves.
03:00 - 03:30: Opened diverter. Engaged and released timelock plug.
03:30 - 03:45: Performed TBT for RIH with timelock plug as drift using manual slips.
03:45 - 07:00: RIH with timelock plug from 442 m to 935 m to drift 9 5/8" liner.
07:00 - 07:30: Performed TBT with new crew for drifting 9 5/8" liner
07:30 - 09:15: Lined up manifold and shakers for washing down.
09:15 - 10:00: Started pumping drill water from rig pumps, 300 LPM. RIH to 938 m. Increased rate to 1100 LPM and washed from 938 m to 940 m.
10:00 - 10:15: Performed TBT prior to POOH.
10:15 - 12:30: POOH with timelock plug from 940 m to 572 m while filling pipe with trip tank pump. Pulled at restricted speed to prevent swabbing.
12:30 - 14:45: Lined up to perform line test from cement unit against IBOP. Tested same to 500psi, no good test. Troubleshot and re-tested line-up from cement unit. Not able to get good test through standpipe. Performed line test against valve k-1 on kill manifold, good test.
14:45 - 15:15: Performed TBT for setting timelock plug. Recorded up/down weights prior to setting plug.
15:15 - 15:45: Sat timelock plug at 600 m according to archer procedures.
15:45 - 16:00: Closed ball valve and pressured up string to 35 bar to verify same closed. P/u and released RT from plug.
16:00 - 16:45: R/u side-entry assy and TIW valve. Performed line test with cement unit. Test OK.
16:45 - 17:30: Filled well with drill water above diverter packer, closed same.
17:30 - 18:00: Pressure tested casing with drill water from cement unit through side entry in drill string. Pressured up to 10 bar reference pressure using 190 ltr. Pressured up to 24 bar using 65 ltr and held pressure for 5 minutes. Pumped up to 28 bar using 16 ltr and held pressure for 5 min. Continued pressuring up to 32 bar using 16 ltr. Pressure broke off and dropped to 22 bar, pressure stable at 22 bar.
18:00 - 18:30: Evaluated situation.
18:30 - 19:15: Bled off 22 bar pressure on casing. R/d side entry assembly. Performed TBT with new crew.
19:15 - 19:45: Opened diverter packer. Engaged and released timelock plug according to archer procedures.
19:45 - 20:45: POOH with timelock plug from 602 m to 425 m while filling pipe with trip tank pump. Pulled at restricted speed to prevent swabbing.
20:45 - 22:45: POOH with timelock plug from 425 m to 8 m. Pulled at restricted speed to avoid swabbing.
22:45 - 23:00: L/d primary timelock plug and inspected same. No damages observed on packer elements.
23:00 - 23:15: P/u backup timelock plug.
23:15 - 00:00: RIH timelock plug on 5 1/2" DP from 8 m to 168 m. Avg. Tripping speed 213 m/hr.

24-hour summary: Attempted to pressure test casing to 34 bar without success. Released timelock plug and RIH to top of screen hanger with same to drift 9 5/8" liner. Re-set timelock plug in 9 5/8" liner. Made new attempt to pressure test casing. No good test. Released timelock plug and POOH with same. M/u and RIH backup timelock plug to 168 m.
