Background of the gf6 in the u.s. and around the world

The GF6 and a seismic source are used together to generate and collect the seismoelectric signal. The seismic source is used to create a sound wave (pulse). When the sound wave moves through aquifers the water in the aquifer moves relative to the rock formation (most of the movement occurs at the top and bottom interface of the aquifer). Ions in the water are dragged away from their partners bound to the rock and the electrical disturbance created travels to the surface at the speed of light and is detected by the antenna array. Each signal is separated in time from its neighbors by the propagation time of the down going seismic pulse. This gives unambiguous depth and thickness data, as with reflection seismic. The form of each signal gives information about the depth, thickness and quality of the aquifer and this is used to estimate the likely yield from a water well drilled at the survey site.

In 2001 Ervin Kraemer brought the technology into the U.S. for the first time.
Since that time he has personally conducted himself and/or assisted with over
3,200 U.S. surveys performed and over 32,500 soundings completed.
•Canada: Nearly 150 surveys performed and over 800 soundings completed.
•Mexico: Over 50 surveys performed and nearly 400 soundings completed.
•New Zealand: Nearly 400 surveys performed and over 4,000 soundings completed.
•Australia: Nearly 40 surveys performed and over 300 soundings completed.
•Africa: Dozens of surveys performed.
•Europe: More than 100 surveys performed.
•India: More than two dozen surveys performed.
