Abstract:
The invention is an electric seismic vibrator source of the type used in seismic prospecting for hydrocarbons that creates a quasi-impulsive burst of seismic energy onto the ground and into the earth. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground. All of the linear electric motors are driven against the ground in a high power pulse that delivers a band-limited spectrum of seismic energy over a very brief period of time that would like a “pop” and be measured in milliseconds. A quasi-impulsive seismic pulse would create a wave field that resembles the seismic data acquired using dynamite or other explosive seismic systems without the ultrahigh frequencies of a true explosive pulse. The quick burst or several quick bursts may further speed up the survey by minimizing the time that a vibe spends on a source point.
