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 rocks local to borehole. Although the results of borehole surveys are often directly useful, they can sometimes be used to constrain the interpretation of surface geophysical methods.
