borehole resistivity surveys

Borehole resistivity methods measure the electrical resistivity of the subsurface by lowering a probe down a borehole. Borehole resistivity can be used to study lateral changes and vertical cross sections of the natural hydrogeologic setting. Borehole resistivity can also be used to study soil and groundwater contamination.

Our company has conducted numerous borehole resistivity surveys. All resistivity surveys are conducted by registered professional geologists. We can travel nationwide or worldwide to conduct a borehole resistivity survey.

Borehole Resistivity Applications:

• soil or rock lithology
• aquifer thickness
• water quality or contamination
• saltwater/freshwater interface
• mapping clay layers or sand deposits
• mineral exploration

Borehole Resistivity Method

Resistivity logging is an electrical method that involves lowering a resistivity probe down an uncased borehole and taking measurements below the water table. The electrode configuration consists of surface electrodes and a probe consisting of borehole electrodes.

The electrical resistivity logging tool obtains geologic information from several feet around the borehole. The borehole resistivity probe takes resistivity measurements to a depth of 500 feet.

Company Background
