The Seismoelectric Survey Method

The seismoelectric method is a reliable geophysical technique used to locate and quantify underground water sources by inducing an electrical signal from groundwater. With our computerized seismoelectric technology, we collect electric signals generated by seismic compression (sound) waves that are sent deep into the ground. The compression wave slightly displaces the water within saturated layers of sand, gravel, sandstone, and fractured rock. This microscopic movement of water generates a measurable electric signal (like static electricity) that travels to the surface and is recorded by our sensitive instruments.

By measuring these precise electrical responses, we can accurately determine the location and viability of an aquifer before drilling begins.

Unlike traditional electrical resistivity or seismic surveys—which only tell you where structural changes are—seismoelectric surveys are uniquely sensitive to the fluid itself. If there is no water to displace, no electrical signal is generated, making it an excellent tool for reducing the risk of drilling dry holes.

Geologic Assessment

The Seismoelectric survey is coupled with a comprehensive geologic evaluation utilizing readily available industry information. The topography, climate, site geology, hydrology, faulting, and surrounding well information are used to develop an understanding of subsurface conditions. The assessment is prepared by a California-licensed Professional Geologist with over 20 years of industry experience.
