    • Methods, apparatus and systems for controllably mobilizing, flowing and maneuvering the flow of hydrocarbon-containing materials within and about a subterranean reservoir. The system comprises selectively positioning at a ground surface level above a subterranean reservoir containing hydrocarbon-containing materials, at least three seismic apparatus spaced apart in a triangulated configuration. The system is provided with an electronic seismic control device configured to controllably communicate with and cooperate with each of the seismic apparatus to concurrently modulate the amplitudes and frequencies of the vibrational energies produced therefrom. The system is provided with a sensing apparatus configured to detect and monitor changes in the fluidity and movement of the hydrocarbon-containing materials about the subterranean reservoir. The electronic seismic control device is controllably manipulated to precisely modulate the frequencies and amplitudes of the seismic vibrational energies emitted by each of the seismic apparatus to controllably maneuver the flow of the fluidized hydrocarbon-containing materials about the subterranean reservoir.
