We are back to making good progress with hole opening and it looks like we may have the water flow problem (at least partially) under control. On Thursday, we were able to run two sweeps of lost circulation material (a paper based product) through the system and that seems to have slowed down the loss of drilling fluids through the permeable pillow intervals that were giving us problems. Drilling through the hyaloclastite interval from 2130 m to 2230 m went fairly fast. The pillow intervals seem to be more difficult to drill and the massive unit at 2312 m has proven to be tougher yet. We tripped yesterday afternoon to change the bit. We are now at a depth of 7612' (2320 m).
