Abstract: The invention relates to a downhole inertial mass seismic-source system, apparatus and method for use within a wellbore environment to provide seismic signal energy at a wellbore location. The system comprises a first inertial mass apparatus with a fluid plunger that is in contact with a first wellbore fluid chamber and a second wellbore fluid chamber, a second inertial mass apparatus with a fluid plunger in contact with the first well bore fluid chamber, a third inertial mass apparatus with a fluid plunger in contact with the second well bore fluid chamber, an Inertial Mass Control System (IMCS) connected to the first inertial mass apparatus, and a power source providing power to the Inertial Mass Control System.
