comments: Zeroed stroke counters for mud pumps. Continued displacing cement with 86.8 m3 OBM at 2000 lpm / 40 bar using mud pumps. Wiper plug sheared at 120 bar / 3380 stks. Slowed down rate to 1000 lpm / 16 bar (FCP) approx 4 m3 prior to bump. No bump observed. Stopped after pumping 3980 strokes, theoretical volume + 1/2 shoe track. No losses during displacement. Monitored for back pressure. None observed.

comments: Set seal assembly according to Vetco procedure. Performed line test of surface line against fail safe valve to 290 bar / 5 min. Ok. 28 ltrs pumped and 28 ltrs bled back.  Closed upper pipe ram and lined up TDS to trip tank to monitor for returns. Pressured up in stages to 207 bar below closed ram. Bled off pressure to zero. Opened rams and took 30 MT overpull (110 MT on weight indicator). Closed ram and pressure tested seal assembly 35/290 bar for 5/10 min. Dropped 1.5%. 380 ltrs pumped and 380 ltrs bled back. Reduced overpull to 3 MT. Rotated 4 right-hand turns and released PADPRT.
