The Study of Seismo-electrical Effect for Subsurface Water Detection

Seismo-electrical data is a special signal while seismic travelling through the pore fluid media. Due to its sensitivity to the fluid, it can be employed for water resource detection beneath the earth. In this paper, we discussed the property of the seismo-electrical data with the simulated data. It shows that two kinds of electrical data will be generated, the coseismic and radiated wave. The radiated electrical signal is generated from the fluid interface and brings valuable information underground. After that, an experiment was introduced to show the application of seismo-electrical prospecting. The data processing and interpretation were presented after acquiring data from field. The results confirm the previous analysis, and suggest that the seismo-electrical technique can help to detect the water layer at depth of more than 1000m.
