Cutting samples showing mostly cement grains. The two boxes to the left show pinkish coloured cement chips, from cuttings from 1911 m depth. The boxes to the right show more reddish cement cuttings, from about 1921m depth.

Yesterday, just before noon and after drilling through a soft cement plug, a solid one was reached at 1910 m depth. While drilling through the soft plug, a few pills were pumped down with the circulation fluid to clean the well. From noon yesterday the ROP has been kept around 0.5 m/h and the WOB has gone up to 5 tonnes. Side-track drilling commenced yesterday at 13:00 hours, first by attempting to form a ledge at 1911 m depth by sliding repeatedly over the same interval. At 16:25 pm the actual side-track drilling started and is still continuing today. Circulation losses are around 5.5 L/s this morning.
