Borehole Geophysical Methods

Geophysical methods are applied both from the ground surface and within boreholes. This section discusses most of the commonly used borehole techniques. These techniques provide detailed properties of the subsurface materials local to a borehole. Although the results of borehole surveys are often directly useful, they can sometimes be used to constrain the interpretation of surface geophysical methods.


The pages found under Surface Methods and Borehole Methods are substantially based on a report produced by the United States Department of Transportation:
