Image log analysis of in-situ stress orientation, breakout growth, and natural geologic structures to 2.5 km depth in central Scandinavian Caledonides: Results from the COSC-1 borehole
This paper presents a detailed description of the stress-induced structures observed with acoustic imaging in a deep borehole in western Sweden, an area where few measurements of this sort have previously been made. The occurrence of breakouts and foliation data are used to constrain the geotectonic models, and these data are fully integrated with lighological data and put into structural context. By far the most interesting aspect of this work is the time-delayed overlap in image logging that is documented: a rare dataset indeed. The interpretation made by the authors on borehole breakout creep over time is also interesting and worthy of consideration by geomechanisists working with these types of data for stress characterization.
