Borehole Geophysics as Applied to Geohydrology

A large amount of geophysical data is recorded in water wells and test holes but interpretation is subject to significant uncertainties. The data are used in ground-water models; to evaluate potential waste disposal sites; the effects of ground- water contamination, and to guide aquifer development, including geothermal reservoirs. The development of quantitative log interpretation techniques to derive more accurate data and to evaluate the statistical uncertainities in the data will reduce costs in ground-water investigations. Project objectives are to evaluate presently available logging equipment and log intrepretation techniques and develop improved instrumentation and analytical techniques for specific ground-water problems such as: site selection and monitoring for disposal of radioactive, municipal, and industrial wastes; improve log derived data such as porosity; attempt to relate the log character of fractures to their hydraulic conductivity and to refine computer techniques for plotting hydraulic conductivity proflies from logs; develop the capability of making quantitative intrepretation of borehole gamma spectra; and to make a statistical analysis of the magnitude and sources of errors in log derived data.
