    Borehole geophysics is an aspect of geoscience that deals with the vertical analysis of the conditions of the subsurface and its fluid content. It is the technique employed in order to have a firsthand well evaluation in the exploration for hydrocarbons. One of the main results of Borehole Geophysical experiment is the Time to Depth relation curve. borehole. The gamma log often is used to define lithology and correlate geologic units between boreholes.

Geophysical well logging is a mature technology comprising many separate systems. It is well beyond scope of a short article like this to detail the science and the results of .

    Geophysical logging techniques have been widely used in the investigation of wells drilled for hydrocarbon exploration, as they provide important in-situ properties of possible reservoir rocks. This chapter focusses on the application of geophysical logging techniques that are of special relevance to environmental investigations. 1. Introduction to Borehole Geophysics techniques The importance for ground water exploration is to: ¾Assist in the hydrogeological assessment of an investigation area. Logging in exploration wells is undertaken to collect the information on physical parameters of individual subsurface rock layers which canFile Size: KB.
