Abstract
The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. 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 in a recurring fashion along with driving the source from location to location through a survey area. The seismic source includes systems for driving the acoustic energy systems using electric energy concurrently from both the generator and an electric energy accumulator such as a capacitor or battery, systems for adjusting the weight on the acoustic energy delivery system by raising and lowering wheels individually and an active energy isolation to isolate the chocks and impulses of the acoustic energy delivery system from the remainder of the seismic source.
