The Best Geophysical Imaging Systems

Geophysical and IP Imaging Case Histories

Using geophysical resistivity equipment and IP imaging systems for many projects around the world has led to discoveries of ancient artifacts to groundwater necessary for survival. Using this equipment has helped researchers and scientists learn more about the history and identify the makeup of an area below the surface as well.

Finding Buried Indian Remains

Using the Sting/Swift, archeologists in Mitchell Springs, located in Southwestern Colorado, performed surveys in an area where they suspected remains of dwellings and kivas existed. Known as pueblos and kivas, the structures were built by the Anasazi People between 800-1200 A.D. Pueblos are normally found underground at a meter or more, while kivas are often deeper. Walls of the structures were made of sandstone, while the interiors were filled with soil, wood, ash, and artifacts. The equipment identified areas where structure walls existed and one anomaly on the graphs showed where a large pit with buried debris existed. In addition, human remains were found in the area as well.

In 2006, using the SuperSting R8/IP, the Engineering Battalion in Thika, Kenya, conducted a deep groundwater survey as part of a training program. The engineers combined three electrode arrays in one survey, which allowed high resolution and deep penetration. In fact, the deep penetration reached 375 meters. Using the AGI Earthlmager 2D inversion software, the electrode arrays were able to be inverted together.

Induced Polarization

In October 1999, in order to investigate a karstic limestone area using resistivity and induced polarization in Austin, Texas, scientists used the Sting/Swift with 28 stainless electrodes at one-meter spacing. The project demonstrated how the AGI Sting R1 IP system images not only standard resistivity but also mapping induced polarization.

Cave and Void Detection

In 1998, researchers needed to locate an underground tunnel in Mery Sur Oise, France, which had been used as a production site for V1 rockets during World War II. The researchers used the Sting/Swift with 28 electrodes at eight-meter spacing and processed with inversion using the Res2Dinv software to pinpoint the location of the tunnel.

These resistivity projects demonstrate the accuracy and precision necessary in geophysical resistivity equipment and IP imaging systems. Throughout the world, researchers and scientists depend on this type of equipment to conduct complicated measurements and surveys in order to achieve specific goals.
