JA Daily Science Report for Expedition 312, 16 November 2005


LOCATION: Site 1256


SCIENCE UPDATE: After reentry the formation began taking weight at 926.6 mbsf. The top drive was picked up, the center bit was dropped, and we began to wash and ream to the bottom of Hole 1256D. The hole is tight between 926.6 and 932.6 mbsf. We were unable to pass an obstruction at 1050.6 mbsf.  We pulled back to 924.6 mbsf, pumped a 50 barrel high viscosity mud pill, retrieved the center bit and dropped a core barrel. We are continuing to wash and ream the tight Hole section between 926.6 to 942.6 mbsf.
