comments: Drilled shoetrack from 1348 m to 1350 m MD. Meanwhile held pre-job meeting before displacing well to 1,40 OBM. Emptied slurry holding tank into pit #1 and #5 to obtain more buffer for cuttings slurry. Pumped hi-vis .Displaced well from seawater to 110 m3 1,40 OBM. Stopped pumping when OBM interface at surface.
