A new technological concept for locating groundwater with exceptional accuracy, low cost, and simple operation procedure.

Where there is the seismoelectric signal, there must be groundwater. If there is no seismoelectric signal, there will be no groundwater.

The DC-4500 Seismoelectronic Groundwater Locater is designed to receive both seismic and seismoelectric signals from the same seismic source in a signal instrument. It can provide the depth and thickness of aquifer, and estimate groundwater conductivity directly. It also carries on the 2-D seismic refractions or reflection survey in order to obtain geological information around aquifers.

DC-4500 water locator can also be used in civil engineering for determining the depth, thickness and conductivity of underground aquifer.

The seismoelectric survey is the only geophysical survey that can provide the groundwater conductivity directly. This method is different from the seismic or electric survey procedure, which registers only seismic velocity or resistivity data in the aquifer. Based on a highly advanced development of Seismoelectric theory, the Seismoelectric signal is produced by a seismic wave traveling through a water-saturated formation, It travels with seismic wave velocity and frequency and it related to permeability of the aquifer.The Seismoelectric signal is an indicator to groundwater. The DC-4500 is patented in US and China.

Biography

Founder and Owner of Seismo Electronics LLC.

BS China Petroleum university in 1982; MS Colorado School of Mines in 1990,

worked on his Ph.D program in Colorado School of Mines on seismoelectric theory until 2000.

He started his career since 1970 as an reservoir technician in Jilin oil field China. He then worked as a geophysicist in civil engineer in Beijing. After moving to the US, he worked as a geophysicist in mining, enviroment and oil exploration, include numerous foreign assignments.

He started doing seismoelectric research in 1988 at Colorado School of Mines, under the aegis of Dr. J. E White, Dr. George Keller and Dr. Skokan. He completed his Master Thesis " Seismoelectric Effect" in 1990. He continued seismoelectric research in his PhD program in CSM until 2000. Most of the theory and practice supporting his invention of DC-4500 are based his unpublished PhD thesis “Using Finite difference Numerical Models of Visco-Elastic Seismic wave form to Model Seismoelectrics signals”.

His is working for Seismo Electronics LLC. To develop business and research on the groundwater locators.
