This presentation introduces the viewer to borehole geophysical tools commonly used in hydrogeologic investigations. These tools include gamma, temperature, conductivity, caliper, borehole video, acoustic and optical televiewers, heat-pulse flowmeter, and borehole deviation.. Examples and case studies follow illustrating the usefulness of data obtained through the utilization of these tools, especially when used to design packer tests and multi-level discrete-zone sampling strings. In addition, borehole tools commonly used in shallow oil/gas well abandonment are presented.
