Technical Examples

A method of conducting seismic evaluation of a subterranean formation wherein a rigid, elongate member having a first end and a second end is positioned such that the first end of the elongate member is at a point on the earth's surface, imparting an impulsive force to the elongate member to urge the member into the earth, the positioning of the rigid member and the impulsive force being sufficient to generate and propagate primary seismic waves into the subterranean formation and positioning one or more seismic wave detectors on the surface of the earth to detect and receive reflected seismic waves from the subterranean formation.
