In borehole investigation, geophysics provides a means of evaluating a great variety of physical properties of subsurface rocks, sediments and fluids. Borehole logging offers an economical alternative to continuous sampling or coring, furnishing continuous, objective data sets in a graphical form that can be rapidly interpreted in the field. Additionally, geophysical logging provides information about the subsurface that cannot be obtained through standard drilling and sampling techniques.
When the geological and hidrogeological data are lost or insufficient, geophysics can bring precious information, sometimes being the only meaning to obtain an image of geological layering.
In aquifer exploitation drilling, geophysics can contribute with important information at determining the characteristics of the aquifer and establish the technical requirements for borehole tubing.
