Applied Geophysics, Inc., with headquarters in Salt Lake City, Utah, has served the U.S. and international oil, gas, and mining exploration communities since 1971. By January 2006, AGI had successfully completed 267 airborne survey contracts (386 survey grids); acquiring, processing, and interpreting 1,372,535 line kilometers of fixed wing and helicopter-borne data in 30 states, plus extensive surveying in Paraguay, South America. Included in these statistics are 177,000 line kilometers of data flown for the U.S. Geological Survey in 18 states. At present we have no survey aircraft, but we subcontract the flying to other competent organizations. An important specialty is obtaining more and better geologic information from previously flown surveys.

In addition to the long-standing history of accomplishments outlined above, AGI in 1975 developed the first microprocessor-based digital data acquisition system designed for airborne applications - the Commander 7000, a predecessor to the personal computer. In 1980, AGI was the first organization to successfully fly and compile continuous flight path at low levels in rugged topography with an inertial navigation system (a DOE funded project). That was before the advent of GPS. AGI was also instrumental in convening the First International Conference on the New Basement Tectonics in 1974, primarily through the efforts of its founder and chief geophysicist, S. Parker Gay, Jr. These conferences, held every two years, have helped focus the attention of explorationists and academicians worldwide on the importance of basement control on the geologic development of the earth. Additionally, the Basement Tectonics Conferences are in part responsible for the recognition of, and resurgence of interest in, the influence of basement geology on the development of structural and stratigraphic hydrocarbon traps in the overlying sedimentary section.{}

For twenty five years, through the many ups and downs of oil, gas, and mineral exploration, Applied Geophysics has engaged in a research and development effort directed toward improving the interpretability of aeromagnetic data. The goal of this effort is to bring geological interpretations of these data within the capability of the explorationist not trained in potential field geophysics. This effort bore fruit early on with the development of NewMagŪ, a data reduction technique which isolates and maps the effects of geologically significant basement features such as faults and lithologic contacts. Fine scale features associated with subtle variations in the lithology of the basement surface are also well displayed. In the twenty three years following the development of NewMagŪ, Applied Geophysics has applied these procedures in over 100 exclusive and non-exclusive surveys for over 170 clients in 25 different petroleum basins. In addition to NewMagŪ clients, 124 different organizations utilized AGI's geophysical services during our early years in over 300 separate mineral exploration projects (1971-1981).

In view of the recognized importance of basement control on structure and stratigraphy in the overlying sedimentary section of many basins, NewMagŪ, can provide your company with a significant competitive edge by supplying you with geologic information heretofore unavailable.
