Activities:
comments: 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.

comments: 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.
