comments: Drilled 17 1/2" hole from 215 m to 266 m using 5 1/2" HWDP as drilling stand; 3100-3400 lpm, 75-87 bar, 60 rpm, 1-6 kNm, 1 MT WOB. Up weight 97 MT/down weight 93 MT. Pumped 10 m3 hi-vis sweep and spotted 10m3 hi-vis on bottom prior to each gyro run. Performed gyro survey every single drilled.  Strapped pipe to one side at centralizer deck using 6 MT moonpool tugger to enhance quality on survey. Gyro kept hanging up while RIH at 110 m from bit (inside 5 1/2" HWDP) and needed several attempts to be able to pass.
