comments: Lined up for mud displacement. Pumped 8 m3 WBM spacer and 10 m3 hv-vis OBM spacer. Tripped in to TD at 2284 m MD. Pumped 200 m3 og 1,30 sg OBM at 3000 lpm / SPP 170 bar. Decreased pump rate to 1000 lpm / SPP 25 bar towards end of displacement. Took WBM back to pits and separated treatable and non-treatable interface.

comments: RIH to 2280 m MD and attempted to establish drilling parameters. Pumped at 3000 lpm but got overflow on shakers. Cut back rate to 1700 lpm to be able to handle flow. Stepped up rate to 3000 lpm as dictated by flow on shakers.
