comments: Performed line test of cmt hose to 345 bar/10 min. Ok. Pumped 8 m3 of base oil at 1760 lpm followed by 20 m3 1.67 sg tuned spacer E at 1760 lpm using rig pumps. Chased spacer to drill floor with 3 m3 OBM. 

Lined up to pump from cmt unit. Opened lo-torque valve with 20 bar on cmt line to verify line-up. Released btm dart for btm plug. Mixed and pumped 23.25 m3 1.90 sg silica cmt slurry at 800 lpm / 32 bar and 7.0 m3 g-cmt slurry at 800 lpm/ 20 bar.

comments: Displaced cmt to rig floor with 500 ltrs of DW at 1000 lpm. Released top dart and pumped 1500 ltrs at 1500 lpm behind cmt using cmt unit. Top wiper plug sheared at 158 bar after 750 ltrs pumped.

Lined up through to top drive and zeroed stroke counters on mud pumps. Continued dispacing cmt by pumping OBM at 3000 lpm.  Sheared btm plug at 7219 strks (159.8 m3) / 155 bar. Reduced rate to 1200 lpm at 8400 strks (185.7 m3). FCP was 53 bar. Bumped top plug at 8552 stks (189.0 m3) / 142 bar.

comments: Pressured up surface lines to 140 bar to equalize and open lo-torque on cmt head. Attempted to close IBOP. No go. Bled off pressure to 95 bar, closed IBOP and continued to pressure up csg to 345 bar. Bled off standpipe pressure to 25.7 bar and monitored for leak through IBOP. Performed pressure test of 13 3/8" csg to 345 bar / 15 min, Ok. Bled back pressure to 20 bar and monitored for back flow. No back flow observed. 2.9 m3 pumped and 2.9 m3 bled back.
