comments: Pumped 15m3 1.3sg 400kg/m3 LCM pill @ 550 LPM. 
When pill starts to exit string, decreased pump rate to 160l/min. Lined up TT and kept volume in TT static by adjusting pump rate between 160-200l/min to avoid LCM going up annulus and avoid SW from annulus dropping down and mix with LCM. 
Pumped and pulled to top of stand when +/- 2 m3 LCM left in the DP string. Stopped pumping after all LCM volume out of the DP string.   
Loss rate during pumping and displacing LCM pill +/- 11m3/hr
