Hourly activities:
00:00 - 01:15: Continued to trouble shoot MWD transmision failure. Down linked tool to 3 bit signal density. Started with bit on bottom and reduced pump rate to keep tool in sync. Got good signal with valid drilling parameters.
01:15 - 04:15: Drilled 12 1/4" hole from 2576 m to 2616 m MD with 1. 35 SG OBM, 3340 LPM, 200 bar, 180 RPM, 30 KNM, 2-3 MT wob, ECD 1. 365, ROP 20-25 m/hr. Down linked and performed survey as required. PU off bottom and observed well for losses at 2607 m. Well was static.
04:15 - 04:45: Lost signal from MWD tool on connection. Started with bit on bottom and reduced pump rate to keep tool in sync. Got good signal with valid drilling parameters.
04:45 - 06:00: Drilled 12 1/4" hole from 2616 m to 2640 m MD with 1. 35 SG OBM, 3270 LPM, 189 bar, 180 RPM, 30 KNM, 2-3 MT wob, ECD 1. 37, ROP 20 m/hr. Down linked and performed survey as required.
06:00 - 07:15: Drilled 12 1/4" hole from 2640 m to 2647 m MD with 1. 34 SG OBM, 3300 LPM, 202 bar, 180 RPM, 31-32 KNM, 0-1 MT wob, ECD 1. 37, ROP 5 m/hr. Down linked and performed survey as required.
07:15 - 08:30: Reamed from 2646 m to 2610 m while MWD had signal loss.
08:30 - 18:00: Drilled 12 1/4" hole from 2647 m to 2740 m MD with 1. 35 SG OBM, 3300-3500 LPM, 199-230 bar, 140-180 RPM, 28-44 KNM, 6-8 MT wob, ECD 1. 37, ROP 10-40 m/hr. Down linked and performed survey as required.
18:00 - 19:00: Circulated hole clean at 3600 LPM, 230 bar, 180 RPM prior to taking pressure points. Reciprocated string. Specified where to take pressure samples with statoil geologist.
19:00 - 22:30: POOH and correlated into setting depth at 2697 m, 3425 LPM, 216 bar and no rotation. Down linked tool to 6 bit signal density. Took pressure reading with stetho scope at 2679,4 m according to schlumberger instructions. Up weight 141 MT/DOWN weight 142 MT. Pumped OOH after pressure reading from 2697 to 2640 m, 900 LPM, 21 bar, 90 RPM. Observed 10 MT overpull while POOH after pressure reading.
22:30 - 00:00: Had problems down linking to stetho scope. Made 3 attempts, recycled tool, down linked to sleep mode and back and worked with different flow rates before the tool took the command.

24-hour summary: Drilled 12 1/4" hole from 2640 m to 2740 m MD. Circulated hole clean. Took 3 pressure readings with stethoscope in ty formation. Continued drilling 12 1/4" hole from 2740 to 2766 m MD.
