Sting/Swift Case histories from our customers:

Ground water case history (541k PDF file)

Sting/Swift with 56 electrodes locates a water well with 5,100 GPM capacity for the City of Waverly, Iowa. This case shows the profits that can be made by employing resistivity imaging methods in search for community water supplies.

 

Amistad Dam site, comparison of methods

At the Amistad Dam site an investigation was made with a 56 electrode STING/Swift system to determine the location of leaks which have effectively drained the giant dam of water. As it was not immediately obvious which array type would return the best data three different arrays were recorded on the same electrode layout. The resulting three 2D profiles show both similarities and differences.

 

Pellissippi Parkway, sink hole survey

This is a highway built on a location where numerous cave-ins have occurred over the years. The objective at this site was to determine if there were any voids in the subsurface that could be expected to cause another cave-in. At this site the Dipole-Dipole method was used with a 56 electrode STING/Swift system.

 

Sting Cave

This was the first test of the Sting/Swift system for cave investigations. The objective at this site was to determine if there were any caves that had so far not been detected. At this site the Dipole-Dipole method was used with a 28 electrode STING/Swift system.

 

Hyderabad Boulder site repeatability test

This test was done to demonstrate the data quality of the Sting/Swift system. Two independent resistivity sections were recorded on the same electrode layout and the resulting inverted sections compared. At this site the Dipole-Dipole method was used with a 28 electrode STING/Swift system.The geology of the area includes many buried granite blocks, one of which showed up in the measured section.

 

Horizontal Drilling investigation

This investigation was done to demonstrate the feasability of determining the most favourable depth for horizontal drilling using resistivity imaging. At this site the Sting R1 resistivity meter with the built-in Dipole-Dipole array functions were used to acquire a dataset from 28 Swift smart electrodes. Results obtained could explain the reason for time delays in a previous drilling on site and also suggest a more favourable depth.

 

Marine Submerged Survey

A utility tunnel between the mainland and Fisher Island in Miami, Florida was going to be constructed. As part of pre-construction investigations the Sting/Swift system was utilized to obtain a resistivity imaging profile along the stretch of the tunnel. Thanks to the waterproof Swift cable and the extremely high resolution of the Sting R1 resistivity receiver good data was obtained in spite of the adverse conditions with the electrodes in constant contact with sea water.

 

Korean highway tunnel survey

A tunnel was going to be constructed as part of an expansion of an existing highway in Korea. The total length of construction is many kilometers and included a 2 kilometer tunnel. Prior to the start of the tunneling activity, Hyundai Engineering and Construction Co., Ltd. performed a site investigation using their Sting/Swift automatic resistivity imaging system.
