comments: Observed lost return to pit and falling standpipe pressure. Picked off bottom and reciprocated stand from 2827 m to 2841 m MD / 10 rpm.  No drop in active, annulus full, i.e. no downhole losses detected. Ivestigated situation. Inspected lines from pit to TDS, found no leakages. Closed IBOP and attmepted to pump, found that problem was related to the surface system.

comments: Lined up cement unit to circulate on well. Circulated in well at set intervalls using cement unit pumping at 1200 lpm / SPP 26 bar. Reciprocated stand and rotated 10 rpm. Monitoed well on trip tank when not pumping - well static. Performed troubleshooting on pumps and circulation system.

comments: Found likely cause of problem to be blocked splitter valve in suction module. Not able to use pit#7 as active pit. Lined up to pump from pit #15 taking retuns to pit #15 and #7 and used mixpump for levelling the two pits. Stepped up pumprate to 3400 lpm and RIH to 2853 m MD.
