comments: Pumped 490 ltrs water, released dart and continued pumping 400 ltrs water behind cement with cmt unit, to displace surface line volume to rig floor. 

Zeroed stroke counters for mud pumps. Displaced and sheared wiper plug by pumping OBM at 1200 lpm using rig pumps. Wiper plug sheared at 138 bar / 886 ltr.
Continued displacing cement with 102.8 m3 OBM at 2000 lpm using mud pumps. Slowed down rate to 1000 lpm / 33 bar (FCP) approx 4 m3 prior to bump. Bumped plug with 110 bar after pumping 4718 strokes, which gives a pump efficiency of 95.3%.

comments: Bled off pressure to 20 bar and closed IBOP. Equalized pressure and opened lo-torque valve. Pressured up well to 310 bar / 10 min through lo-torque valve to test casing. 1300 ltrs pumped and got 1350 ltrs back. Bleed off and checked for back flow to cmt unit. Disconnected cmt hoses and flushed lines.
