Scientific Core Hole Valles Caldera No. 2B (VC-2B), New Mexico: Drilling and Some Initial Results
Abstract Research core hole VC-2b, the third in the
Research core hole VC-2b, the third in the U.S. Department of Energy�s Continental Scientific Drilling Program efforts in the Valles caldera, was continuously cored to 1,762 km on the western flank of the caldera�s resurgent dome in 1988. Bottom hole temperature is about 295°C within Precambrian (1.5 Ga) quartz monozonite, deep within the liquid dominated portions of the Sulphur Springs hydrothermal system. VC-2b may be the deepest, hottest, continuously cored hole in North America. Core recovery was 99.2%. The only major drilling problems encountered were when temperatures at the bit exceeded 225°C below depths of about 1000m. The result of these conditions was loss of viscosity and/or lubricity in the mud, apparently caused by breakdown of the high temperature polymers.
