Geophysical borehole logging is one of the most powerful tools for understanding fractured bedrock aquifers. By combining electrical, acoustic, temperature, and flow measurements with high-resolution borehole imaging, hydrogeologists can pinpoint where water enters and exits a well—and why. In the images above and below, the acoustic televiewer (amplitude) and optical televiewer reveals distinct planar features cutting across the borehole wall. These sinuous, high-contrast ba
