Tomographic Geophysics for Better Subsurface Geologic Informationby Walter E. Heinrichs, Jr., Heinrichs GEOEXploration Co, United States,
Abstract: Geologic skepticism among engineers owes much of its origin to common ambigueties in geologic interpretations and the innate artistic aspects of geology and its related diciplines. Geophysical tomography provides a new means to reduce some of the uncertainty in geophysical results by allowing for greater resolution and accuracy and, in some cases, by providing real time analysis of on going physical changes in the subsurface. Procedures to do these things were developed and tested synthetically by computer. Results demonstrated the value of simultaneous merging of vertical profiling, slope profiling and surface or horizontal profiling, all into one integrated solution. Examples of these results are presented along with a brief review of the evolution of tomographic geophysics.
