comments: Reduced flow and attempted to come down. Parameters : 1100 lpm / SPP 41 bar / 50 RPM / torque 9-11 kNm. Tagged 2595 m and observed 30 bar increase in pressure. Pressure dropped back to 41 bar after 1 m drilled. Drilled 8 1/2" hole from 2595 m to 2603 with 1.25 sg OBM . Drilling parameters : 1100 lpm / SPP 41 bar / 50 RPM / torque 16-18 kNm / WOB 8 MT / ECD 1.27 sg EMW. 

Observed torque increase and WOB fluctuate from 6-12 MT when stabilizers passed 2595 m. 
Continued drilling 8 1/2" hole from 2603 m to 2616 with 1.25 sg OBM . Drilling parameters : 2000 lpm / SPP 123 bar / 80 RPM / torque 12-15 kNm / WOB 4-7 MT / ECD 1.28 sg EMW.
