The current depth of the SE-2B hole is 80 m, with 55 m completed in the last 20 hours. Filtered, UV-sterilized seawater has been used as drilling fluid and attapulgite mud to condition the hole. The PQ casing of the conductor hole has slipped again, due to issues with cementing beginning three days ago. The HQ casing has been tripped out and the PQ casing will now be hung in place.
