comments: Started pressuring up at well. Pumped a total of 1000 lpm before any pressure build up could be seen, probably caused by drained standpipe. Reset volume counter at 5 bar. Pressured up to 75 bar pumping at 100 lpm. Held pressure for 20 min, observed pressure drop of ~1,6 bar / 10 min and ~1,4 bar / 10 min towards end. Hard to determine if leakage rate was improving. Pressured up to 75 bar again. Held test for another 20 min, observed pressure drop of 1,3 bar / 10 min towards end of test, but hard to see further improvement. Estimated leakage rate approx 1,5 l/min. Volume pumped and bled back 943/910 liters. Decided to continue operations.

comments: Pumped 9 m3 LCM pill at 2000 lpm. Chased LCM with 26 m3 seawater. Found that diplacement/spotting of pill was wrong and that the pill had been overdisplaced/dilluted with approx 8 m3 seawater. Discussed situation. Decided to circulate out LCM pill and mix new LCM.
