00:45 - 02:00: Slacked off weight to neutral, i. E. 80 MT. Checked inclinometer x/y readings 0,02/0,13. Opened ball valve on cart. Bled off pressure above upper FOSV. Relased cart with 5 clockwise turns while observing conductor housing with ROV. Broke and laid down cementing stand. Picked up and made up 5 1/2" HWDP single, inserted sponge ball and made up single.
02:00 - 02:15: Pumped sponge ball at 2000 LPM to clean string. Confirmed adjacent wells de-pressurized at 02 00.
02:15 - 03:15: POOH with cart/stinger on 5 1/2" HWDP from 188 m to 50 m MD. Meanwhile installed CTS pump/funnel on conductor housing using aft crane and ROV.
03:15 - 04:15: Pulled master bushing. Pulled cart through RT. Installed master bushing. Set down cart on master bushing. Removed inclinometer. Screwed out 5 1/2" HWDP single on top of cart. Rigged up c-plate in rotary, and hung off aluminium string on clamp. Broke and laid out cart.
04:15 - 06:00: POOH with 5 ea aluminium singles using clamps, c-plate, tugger and chain tongs. Rigged down c-plate. Cleared drillfloor.
06:00 - 06:15: Cleared drillfloor. Put aluminium pipe in basket.
06:15 - 07:00: Held toolbox talk for making up BHA. Laid 26" bit/stab/motor on HTS.
07:00 - 07:15: Held toolbox talk/handover meeting.
07:15 - 11:15: Made up 26" drilling BHA comprising of 26" bit/stab/motor, GWD and powerpulse. Established scribeline from bent sub to MWD and recorded correction. Made up UBHO and adjusted landing sub as required. Made 8 1/4" DC stand and DC/JAR stand. Recessed operation for TDS service/repair.
11:15 - 19:30: Changed around stabilizing liners on TDS due to observed wear on drillpipe couplings. Observed rear liner crest more worn than front liner crest. Discussed options. Carried out rig repair of worn liner, i. E. Clad welding. Installed modified liner crests on TDS. Comment new stabilizer liners ordered from rig 30/1-09. Order sendt from maersk office in town to supplier 8/4-09.
19:30 - 21:15: Moved diverter away from setback. RIH and stabbed 26" BHA into 30" conductor assissted by ROV. RIH to 175 m MD. ROV hooked up to CTS hose.
21:15 - 22:15: Made up TDS to test modified stabilizing liner on TDS. Observed scores on DP coupling when rotating pipe. Discussed situation. Opened IBOP and rotated pipe observed no contact between dies and DP coupling. Decided to continue operation without repair/modifications.
22:15 - 23:15: Removed masterbushing and installed auto slips. Staged up pumps for washing down inside 30" conductor. Observed large shocks in drillstring. Ran ROV to observation position by CTS. RIH to 180 m MD, no hang UPS observed. Staged up pumps to 3500 LPM and commenced rotation at 60 RPM. Washed down and tagged shoe/top of cement at 201 m MD.
23:15 - 00:00: Drilled cement and shoe. Parameters flow 2300-3500 LPM SPP 48-95 bar 40 RPM wob 1 MT torque 2-3 KNM. Broke through shoe at 203 m MD. Cleaned out rathole down to 207 m MD, reamed back every 2 m drilled.

24-hour summary: Made up and RIH with 26" drilling BHA. Repaired centralizing liners on TDS. Stabbed 26" BHA into conductor. Tested TDS. Washed down to 201 m MD. Drilled 30" shoe and cleaned out rathole down to 207 m MD. Drilled 26" hole from 207 m to 239 m MD. Performed GMWD surveys as required.
