Borehole televiewer data analysis of Hole 504B from Legs 137 and 140

Abstract

AU BHTV data were analyzed for borehole breakouts and fractures and compared with previous results from BHTV measurements at intermediate depth sections of this hole under consideration of ancillary information about the nearby tectonic setting. In addition, disturbed (logging after the end of drilling and circulation and undisturbed logging after reentry temperature profiles through the complete borehole were used to estimate the temperature effect on borehole breakout and vertical fracture initiation. -from Authors
