Activities:
comments: Drilled 17 1/2" hole section 2403 m to 2417 m MD. Drilling parameters : Flow 4500 lpm / SPP 275 bar / 180 rpm / 18 MT WOB / Torque 20 kNm / ECD 1,37-1,38. 

ROP down to 4-6 m/hrs.

comments: Due to decreasing ROP, picked 0,3 m off bottom to clean the bit. Increased pump rate to 4700 lpm and rotated at 220 rpm and held for 10 mins. Got problems with mud pump #3, took pump out of service, reciprocated on stand pumping 2000 lpm. Lined up mud pump #2. RIH and stepped up pumps to 4500 lpm for commencement of drilling.
