ABSTRACT:
Method and apparatus are provided for a new type of geophysical prospecting. The method applies an electric field to a fluid-containing porous subsurface formation to create a fluid pulse from changes in the polarization of pore fluid dipoles. The fluid pulse propagates in the subsurface as a seismic wave that may be detected by an appropriate array of seismic detectors. The apparatus is a pulsed DC or AC source for generating an applied electric field and a seismic detector.
