Abstract
The invention is an electric power accumulator used with 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 to drive a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion. The source may also be designed to use electric power to drive the source from location to location through a survey area. A large electric power accumulator is provided to store electric power when the generator is able to produce excess power and the accumulator may deliver power along with the generator to drive the rods and deliver acoustic energy. With a large electric power accumulator, such as a battery or capacitor, the engine and generator combination may be engineered to be somewhat smaller, less costly and more efficient than a system where the engine and generator were sized to provide the electric power at times of maximum electric draw.
